Sleep disorders following stroke (PSSD) are common complications affecting a significant proportion of patients, with estimates as high as 78%. These disorders greatly impact the quality of life for patients and their recovery of motor functions. This article aims to evaluate the effectiveness of non-invasive brain stimulation (NIBS) as a potential treatment for improving sleep quality in patients suffering from PSSD. Through a comprehensive review of available studies, we highlight how this therapeutic modality impacts sleep parameters, reduces levels of depression, and enhances neurological needs. We will review the methods used in this research, as well as the main results and future recommendations, providing valuable insights for developing effective treatment strategies to address these challenges.
The Importance of Sleep Disorders After Stroke
Sleep disorders after stroke (PSSD) are common complications affecting a significant number of patients, with some research indicating that up to 78% of patients suffer from them. These disorders include several forms such as insomnia, sleep apnea, and excessive daytime sleepiness, which greatly affect the quality of life for patients. A lack of good sleep exacerbates neurological damage and delays nerve regeneration, hindering the overall healing process. Therefore, effective management of these disorders is an important part of the rehabilitation strategy for stroke patients.
Research shows that sleep disorders are directly linked to the ability to recover after a stroke. For instance, good sleep periods play a vital role in enhancing neuroplasticity, which is the brain’s ability to reorganize itself after injury. If sleep quality is affected, this may delay recovery, which in turn impacts the cognitive and motor performance of patients. These disorders can also increase the risk of secondary strokes, raising rates of disability and mortality.
Non-Invasive Brain Stimulation Techniques
Non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), are promising treatments for sleep disorders after stroke. These techniques target the neural circuits responsible for sleep and wakefulness, modifying neural activity and improving sleep quality. For example, TMS works by using a magnetic coil that generates a magnetic field that passes through the scalp and reaches the cerebral cortex. Studies have shown that TMS can improve sleep architecture and increase the duration of deep sleep.
Results indicate that repetitive TMS (rTMS) may improve sleep quality, reduce depressive symptoms, and increase levels of brain-derived neurotrophic factor (BDNF), a factor that plays a vital role in nerve health and neurogenesis. The improvement in sleep status resulting from rTMS is an example of how these techniques positively affect the overall recovery of patients after stroke.
Results of Studies and Comprehensive Analysis
Systematic reviews and analyses of multiple studies have clarified the effects of NIBS on sleep disorders after stroke. Results showed that rTMS, for instance, contributed to a reduction in depression scores and improved sleep quality, with significant improvements reported in the Pittsburgh Sleep Quality Index. Additionally, improvements in BDNF levels were observed in patients, demonstrating the positive impact of these techniques on neurological health.
Moreover, stimulation using TBS also showed improvements in sleep quality in these patients, showcasing both the efficacy and safety associated with non-invasive brain stimulation. Significant improvements in total sleep duration and sleep efficiency were noted, alongside observable positive effects on patient well-being. Compared to traditional therapies, NIBS offers a non-pharmacological solution that can enhance recovery for stroke patients.
Challenges
Future Opportunities in the Treatment of Sleep Disorders
Despite the effectiveness of non-invasive brain stimulation (NIBS), there are still some challenges related to the widespread reliance on these treatments. The consumption of these technologies requires specialized knowledge and dedicated training for healthcare professionals, which limits their availability in some contexts. Additionally, there is a need for further studies to determine optimal treatment criteria, stimulation duration, and the necessary session frequency to achieve the best results.
It is also important to enhance patient access to these technologies through the implementation of educational and promotional strategies to raise awareness of the benefits of NIBS. As research progresses and more confirmed studies emerge, these upcoming treatments could become a preferred option for many patients suffering from sleep disorders post-stroke, contributing to improved quality of life and recovery rates.
Sleep Assessment Indicators and the Role of NIBS in Modulating Neural Circuits
Sleep assessment indicators, such as polysomnography, are used to identify different sleep patterns and evaluate its quality. Research shows an increasing role for non-invasive brain interventions (NIBS) in modulating neural circuits “in vivo.” This is particularly significant as it opens a new avenue to tackle the complex interactions between sleep, neuroplasticity, and functional recovery post-stroke. Sleep quality can impact the recovery of motor and cognitive functions in stroke patients, making the study of the effect of NIBS on post-stroke sleep disorders (PSSD) essential. However, there is a lack of conclusive evidence regarding the effectiveness of NIBS, due to limitations related to sample sizes, diversity in inclusion criteria, and variability in methodologies. This indicates a need for further clinical studies and systematic reviews to evaluate the effectiveness of NIBS in a compelling and organized manner for treating sleep disorders after stroke.
Research Strategies and Selection Criteria for Studies
The available literature was reviewed through a systematic search across several databases such as PubMed, Web of Science, and Cochrane Library, and the first phase of the search retrieved nearly 952 articles, which were filtered to remove duplicates. The study focused on randomized controlled trials (RCTs) discussing the effectiveness of NIBS in treating PSSD. Inclusion criteria involved participation of adults suffering from medically diagnosed PSSD, regardless of gender. Additionally, the quality of the intervention was ensured as NIBS was used for the purpose of assessing conditions, compared to a control group that received routine treatment or sham stimulation. The primary outcomes measured sleep quality using scales such as the Pittsburgh Sleep Quality Index, alongside secondary measures such as certain protein levels and potential side effects. Studies that did not meet the established criteria were excluded, contributing to ensuring the quality of the analyzed results.
Quality Assessment of Studies and Results Obtained
The research team used the risk assessment tool recommended by the Cochrane collaboration, which addressed six areas to ensure the quality of the writings. Studies were evaluated according to criteria such as selection bias, outcome reporting, attrition bias, and others. Among the included studies, despite the majority describing random methodologies, there were some reports that contained biases in how adjustment and follow-up were conducted. Further analyses revealed greater variability in sleep outcomes when studied, helping to deepen the understanding of the impact of NIBS. The main outcome reached was that NIBS significantly contributed to improving sleep quality in many cases, which is a positive point for moving forward in the clinical use of non-invasive techniques.
Data Analysis and Preliminary Results from the Meta-Analysis
A conducted
The meta-analysis summarizes data and aggregates various indicators taken from studied research. Results for improving sleep quality emerged prominently, as a set of studies showed that transcranial magnetic stimulation (rTMS) sessions had a significant impact on sleep quality by reducing Pittsburgh Sleep Quality Index scores. In comparison, the effect resulting from tDCS was less pronounced. This suggests the potential for NIBS to outperform traditional treatment options in improving sleep quality for patients suffering from PSSD. The analysis also demonstrated that high-frequency stimulation had a better effect than low frequency, opening up future studies to evaluate different frequencies and tactics within clinical usage systems.
Conclusions and Clinical Applications
Non-surgical brain interventions have shown promising effects in the field of therapy and rehabilitation post-stroke. In particular, NIBS is a modern and innovative tool that may aid physicians in improving the sleep quality of stroke patients. These effects are backed by evidence from several studies, highlighting the need for more research into combining NIBS with traditional treatments, in addition to new ideas for systematic usage strategies of these interventions. Emphasizing the importance of sleep quality reflects its greater significance in future treatments, contributing to improving the operational life of patients after strokes.
Effect of Non-Invasive Stimulation on Sleep Quality
Non-invasive stimulation plays an increasing role in addressing sleep disorders post-stroke, a vital topic that requires a deep understanding of the techniques used and their effectiveness. Studies have shown that transcranial magnetic stimulation (rTMS) can significantly improve sleep quality compared to groups receiving only pharmacological treatment or sham groups. Comprehensive analyses were conducted, revealing that the sleep quality assessment scores (PSQI) were significantly better in non-invasive stimulation groups. For example, data indicated a clear score difference between the rTMS group and the other group. However, there were no statistically significant differences between the rTMS group and the medication-only group, suggesting that non-invasive stimulation may yield better results, but it is not necessarily a complete substitute for medications.
Sleep is a vital process that affects physical and mental health. Many patients after a stroke suffer from sleep disorders that impact their recovery capabilities. Based on study results, it is evident that incorporating rTMS as part of the treatment plan may significantly enhance sleep quality, aiding patients in resting better and promoting the restoration of their neurological functions after a stroke.
Despite the encouraging benefits demonstrated by the studies, further research is needed to understand how these results can be enhanced. For instance, future studies could focus on the number of stimulation sessions, their frequency, and the interaction with other factors like genetic patterns and patient sleep characteristics. Moreover, understanding the differences between various types of stimulation, such as rTMS and tDCS, can assist in finding more effective therapeutic protocols.
Clinical Efficacy of Non-Invasive Stimulation in Improving Sleep
One of the main dimensions of studying non-invasive stimulation lies in evaluating its clinical efficacy. Advanced graphical analysis shows that non-invasive stimulation treatment led to a marked improvement in sleep quality-related performance metrics. There have been multiple studies addressing the positive effects of various patterns of rTMS and tDCS on patients suffering from sleep disorders post-stroke. By analyzing those results, alongside the available techniques, health services can enhance patient care.
Studies have shown…
The results indicate that the use of stimulation and magnetic stimulation has achieved a significant improvement in the key factors of sleep quality, such as sleep efficiency, time taken to fall asleep, and repeated awakenings during the night. This clinical success may encourage doctors and practitioners to integrate these techniques into regular treatment plans, leading to an enhancement in patients’ lives.
For example, a study showed that the improvement in sleep efficiency in a group of patients who underwent magnetic stimulation sessions was significantly greater compared to the group that received only medication. Such results reinforce the idea that non-invasive stimulation is not just an additional treatment method but an effective option that may have long-term effects on quality of life.
However, caution should be exercised when interpreting this data, as the significant variability in treatment response among patients highlights the necessity of tailoring treatments according to each patient’s condition. There is a possibility that greater improvement could be achieved by combining non-invasive stimulation with other therapeutic aspects, such as psychotherapy and emotional support.
Side Effects and Tolerance to Treatments
Evidence suggests that non-invasive stimulation as a treatment protocol can reduce the rates of side effects compared to traditional treatments. Research indicates that the occurrence of side effects was significantly lower in the non-invasive stimulation group than in those receiving prescribed medications. This positive development is important for doctors and senior practitioners as they work to minimize the risks associated with treatment and achieve effective results without increasing the burdens faced by patients.
Analyses also emphasize the necessity for close monitoring of patients receiving non-invasive stimulation. This is an important part of assessing the benefit of these treatments. Some studies have shown that some individuals may experience different responses to magnetic stimulation, necessitating continuous adjustments to the protocols used. For example, the spectral settings of stimulation devices may require calibration to make the treatment more effective.
Additionally, there may also be a need for awareness and psychological support for patients undergoing such treatments, as this is part of assessing their overall quality of life. Through the insights provided in studies, it becomes clear that treatments that support improving mental and psychological health are an integral part of non-invasive stimulation programs for patients.
This knowledge can be used in clinical practice strategies, enabling the provision of more effective and efficient care for patients. In summary, improvements in clinical outcomes, the notable reduction in side effects, and personalized treatment plans are indicators of a promising future for non-invasive stimulation in treating sleep disorders after a stroke.
The Importance of Sleep for the Nervous System and Neuroplasticity
Sleep plays a vital role in mental and physical health, being one of the key factors that directly impact cognitive performance and physiological processes. Deep sleep, known as slow-wave sleep (SWS), is associated with enhanced neuroplasticity, the process that allows the brain to adapt to changes and repair itself after injuries, such as a stroke. Research indicates that good sleep enhances cognitive performance and the ability to learn, as it helps in forming and strengthening neural connections. For instance, it has been observed that individuals who receive long periods of deep sleep achieve better results in memory tasks compared to those suffering from sleep deprivation. Environmental and psychological factors interact complexly with sleep quality, necessitating research into techniques that can enhance this quality.
Non-Invasive Brain Stimulation (NIBS) Techniques and Their Effects
Non-invasive brain stimulation techniques, such as repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), are gaining popularity as treatments for improving various types of psychological disorders. Studies have shown that rTMS can be used to improve sleep quality in patients with post-selective serotonin reuptake inhibitor (PSSD) sexual dysfunction, where findings demonstrated that combining rTMS with pharmacotherapy increases treatment efficacy. Nevertheless, no significant variance in improvement was recorded between rTMS and pharmacotherapy alone, indicating that the enhancements may result from multiple factors, including the stimulation site, intensity, and treatment duration.
Patterns
sleep and changes in examination standards
Research indicates that PSSD patients experience significant changes in sleep structure, with an increase in light sleep stages (N1 and N2) and a decrease in total sleep time (TST) and sleep efficiency. Responses to treatments such as rTMS and tDCS have proven effective in improving KtS and SE but have not been effective in reducing sleep onset time. Additionally, results have shown that rTMS can reduce certain sleep stages. Therefore, understanding how these techniques affect various sleep parameters requires further study.
Synthesis between different treatments and future research
The possibility of combining rTMS and tDCS with pharmacological treatments represents an important step toward improving treatment planning for patients, and although initial results are promising, there is a clear need for more long-term studies to determine the effectiveness and durability of the outcomes. Identifying the optimal parameters for each therapeutic technique is key to achieving better results, which also necessitates focusing on diversifying the patient sample and potential effects of environmental and psychological factors. In other words, a variety of studies should be prioritized to discover the precise relationship between treatment and improvement in sleep quality.
The impact of non-invasive stimulation techniques on chronic sleep disorders
Chronic sleep disorders are a common health issue that affects individuals’ quality of life and their ability to perform daily activities normally. Modern techniques such as repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) have shown effectiveness in improving sleep quality. Studies have demonstrated that non-invasive stimulation can positively influence sleep quality and individuals’ beliefs about sleep. The dorsolateral prefrontal cortex (DLPFC) is an important center in neural and emotional control, helping to reduce the impact of negative emotions and increasing the ability to recognize positive emotions.
The relationship between stimulating cortical activity and its effect on sleep quality has been highlighted, in light of research indicating that stimulation has yielded noticeably positive results. Techniques such as rTMS are considered very beneficial, although the effects of medications used in the treatment of sleep disorders may play a significant role in treatment outcomes. For example, the use of medications that affect GABAergic and glutamatergic transmissions may lead to conflicting improvements in the effectiveness of these techniques when combined with medications. Drugs such as estazolam are particularly effective in improving sleep but may leave negative effects such as transient drowsiness the next day, impacting mental functions.
Studying the effect of transcranial direct current stimulation (tDCS) on patients with sleep disorders related to strokes is intriguing, as research suggests that stimulating electrical activity in the brain can provide improvements in mood and sleep. Although current research lacks a sufficient number of comparable studies, preliminary results indicate that there is an improvement in sleep quality and alleviation of depressive symptoms.
Improving mood and sleep in PSSD patients
Recent research has shown the impact of non-invasive stimulation techniques on improving depressive symptoms in patients with post-selective serotonin reuptake inhibitor (SSRI) syndrome (PSSD). Subgroup analyses have shown that both rTMS and tDCS had a positive effect on improving mood in these patients. The results confirm the conclusions of meta-analytical studies conducted in 2023, which indicated a close relationship between sleep disorders and negative emotions in stroke patients, where depression and anxiety were found to exacerbate sleep problems.
The role of
Non-invasive stimulation plays a significant role in modulating the excitability of cortical neurons and results in improving the activity of certain areas in the brain, thereby providing enhancements in emotions and sleep for patients suffering from stroke-related disorders. Studies have shown that increased levels of brain-derived neurotrophic factor (BDNF) play an important role in regulating sleep, which is one of the cited relationships between magnetic stimulation and the development of sleep states. Elevating BDNF levels can help improve sleep quality, particularly in the non-rapid stages of sleep and in the transition from stage 3 to rapid eye movement (REM) sleep.
Other potential factors include the relationship between sleep and daily quality of life, as studies have indicated that improving sleep quality can lead to enhanced cognitive performance and memory, which is critical for maintaining quality of life. Therefore, future research needs to examine the effects of transcranial electrical stimulation on BDNF levels in PSSD patients and improve the sleep experience in more detail.
Interactions Between Pharmacotherapy and Non-invasive Nerve Stimulation
Medications play a key role in the effects of non-invasive stimulation on sleep quality, as current results have shown that there may not be a significant improvement in sleep parameters when combining rTMS with medications compared to taking medications alone. However, research suggests that the combined use of neuromodulation technologies and medications may offer new opportunities to address the complex processes related to sleep.
Medications used to treat sleep disorders can significantly influence the effectiveness of rTMS, as the interaction between medications and non-invasive stimulation techniques can yield interesting results. For example, taking estazolam with LF-rTMS has shown greater success especially in improving sleep quality and increasing cognitive performance in older patients. Research indicates that estazolam provides benefits regarding sleep onset speed, but long-term use may show negative effects that need careful scrutiny.
Understanding how medications and non-invasive nerve stimulation interact can contribute to the development of more effective therapeutic strategies. Researchers need to examine how medications affect brain activity and the structural sectors that play a role in the potential improvement or deterioration of mental functions. Therefore, future studies are vital to provide more evidence on how to achieve greater benefits from therapeutic interventions.
Future Research on Non-invasive Stimulation Techniques
Current studies highlight the importance of conducting in-depth research on the application of non-invasive stimulation techniques in treating sleep disorders and related conditions. Preliminary results indicate the effectiveness of these techniques in improving sleep quality and alleviating symptoms arising from mental conditions such as depression. However, the scope of application and analysis of the effectiveness of techniques like TBS and tDCS still requires further investigation.
Research procedures should focus on collecting larger samples and conducting multicenter studies, adhering to strict standards to avoid biases and derive accurate conclusions. Diversity in clinical approaches and methods used in trials, including age characteristics and different health issues among participants, should also be considered. This will enable the development of more suitable and effective therapeutic methods.
Developing non-invasive stimulation techniques requires a delicate balance between clinical outcomes and foundational studies to understand the long-term effects. It is also essential to combine neuroscience with clinical approaches to ensure the best healthcare is provided to patients, contributing to enhancing their quality of life and reducing the negative effects of medications used. In summary, the need for future studies goes hand in hand with innovation in current treatment systems, making it possible to better utilize non-invasive stimulation techniques to achieve the highest levels of health improvement.
Treatment
Light and Its Impact on Sleep and Quality of Life After Stroke
Stroke is one of the leading causes of motor and psychological disabilities, significantly affecting sleep quality. Recent studies have unveiled the effectiveness of bright light therapy as a method to address sleep disorders following a stroke. According to research such as that conducted by HS et al., bright light therapy has shown positive effects on improving sleep quality and mood in patients suffering from insomnia after stroke. The idea is that exposure to bright light at specific times can help adjust the body’s biological clock, thereby enhancing sleep quality.
Light therapy works by simulating sunlight, which helps boost serotonin production, contributing to improved mood and sleep. This type of therapy is used in clinical settings, where patients are directed to receive light treatment at certain times of the day. Clinical trials have demonstrated that patients who received light therapy achieved significant improvements in sleep quality, positively reflecting on their daily lives.
Moreover, light therapy can be particularly beneficial for patients experiencing severe conditions such as post-stroke depression. The treatment generally involves using specialized equipment to emit intense light, which directly affects electrical activity in the brain and reorganizes normal sleep patterns. These benefits support the notion that light therapy is not just a treatment for symptoms but can also enhance the psychological and emotional state of patients after a stroke.
Acupuncture as an Effective Treatment for Insomnia After Stroke
Research indicates that acupuncture represents another effective option for treating insomnia faced by patients after a stroke. Zhou et al. conducted a systematic review of multiple studies involving 26 randomized controlled trials and found that acupuncture had a strong effect on improving sleep quality. Acupuncture works by stimulating specific points in the body, believed to enhance energy flow and relieve tension and anxiety.
Supporting research highlights acupuncture’s ability to modify the chemical balance in the body, including hormones that control sleep. This process promotes the release of melatonin, known for its role in enhancing natural sleep. Similarly, there are numerous patient experiences illustrating how acupuncture positively affected anxiety and depression levels, thereby improving overall sleep quality.
Furthermore, acupuncture is considered a good alternative to traditional pharmaceutical treatments, especially for patients who cannot tolerate medications or suffer from side effects. This treatment promotes the concept of complementary care, where therapies such as light therapy and acupuncture can be combined to achieve the best possible outcomes in treating insomnia after a stroke.
Transcranial Magnetic Stimulation and Clinical Applications for Insomnia After Stroke
Recent research has focused on using transcranial magnetic stimulation (TMS) as an effective tool for treating insomnia after a stroke. Studies by Lanza et al. indicate that TMS can modify electrical activities in the brain, helping to restore normal sleep patterns. The treatment involves sending magnetic pulses to specific areas of the brain, and numerous trials have shown that this therapy leads to noticeable improvements in sleep and quality of life for patients.
By targeting specific areas associated with sleep and mood, TMS can induce positive changes in the brain’s neural circuits. For example, one study by Jiang et al. showed TMS’s effectiveness in reducing insomnia levels and improving psychological well-being for patients who had experienced a stroke. Magnetic stimulation does not cause significant pain and is considered a safe treatment compared to traditional medications.
As research continues to grow…
The popularity of this technology in clinical practices, where TMS is used not only as an alternative to medication but also as part of a comprehensive strategy for the treatment of insomnia. Magnetic stimulation opens a new horizon for the care of stroke patients, helping them restore the quality of their sleep and thus improve their quality of life.
Sleep Disorders After Stroke
Sleep disorders after a stroke are common complications faced by patients following the incident, with research indicating that up to 78% of patients experience some form of sleep disturbance. Among these disturbances, post-stroke insomnia is one of the most common patterns, with prevalence rates ranging from 30.1% to 46.5%. This condition shows a significant impact on patients’ quality of life, affecting their ability to concentrate, mood, and overall health. Additionally, sleep disturbances can lead to further delays in the recovery process from a stroke.
It is important to understand how a stroke affects the brain structures that control sleep, such as the limbic system, the pituitary gland, and essential sleep circuits. The effects of a stroke vary depending on the sites of injury, leading to multiple impacts on the level and functioning of sleep. Recognizing and treating these disorders is essential for improving the quality of life of patients and helping them cope with the challenges they face after a stroke.
Studies indicate that sleep disturbances exacerbate other issues related to stroke, such as depression and memory loss. Good sleep has been shown to be crucial for brain health, and thus addressing sleep disorders can have positive effects on overall recovery. For instance, improving sleep quality may enhance cognitive performance and psychological support, alleviating the negative symptoms of stroke.
Non-Invasive Brain Stimulation Techniques
Recent research suggests that non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), may be effective in treating sleep disorders after stroke. These techniques are considered a potential alternative to medication, as they work to modify electrical activity in the brain and increase blood flow to areas responsible for sleep.
Several studies show that low-frequency transcranial magnetic stimulation can significantly improve sleep quality, reducing episodes of insomnia in patients. For example, a 2022 study found that using TMS at low frequencies contributed to improving the sleep condition of patients suffering from insomnia after stroke. The technology supports new strategies for treatment and is often used in conjunction with cognitive behavioral therapy (CBT) for better results.
These stimulation techniques require specialized expertise, but the potential benefits make them an attractive option for patients and neurologists. Furthermore, these treatments are not associated with significant side effects, making them a possible alternative to traditional treatments such as sleeping medications.
Treating Insomnia Using Behavioral and Psychological Therapies
Treating sleep disorders after a stroke sometimes goes beyond medical uses. Evidence suggests that cognitive behavioral therapy for insomnia (CBT-I) can be particularly effective in addressing post-stroke insomnia. This type of therapy targets negative thinking patterns and habits related to sleep, working to replace them with positive ones. CBT-I strategies involve improving sleep habits, and there has been notable success in enhancing sleep quality among patients who received this treatment.
Programs also include relaxation and meditation techniques, which have been shown to reduce anxiety levels and facilitate sleep. The therapy focuses on developing a regular sleep routine and addressing the psychological factors leading to sleep problems. Results from the use of CBT-I among patients who experienced a stroke have shown significant improvements in sleep quality and mood.
the role of sleep disturbances in stroke recovery
Sleep disturbances after a stroke can significantly impact patient recovery and overall well-being. Recognizing the importance of sleep in the rehabilitation process is crucial for developing effective treatment strategies. The connection between sleep quality and brain health suggests that addressing sleep-related issues can enhance recovery outcomes. Therefore, healthcare providers should prioritize the assessment and management of sleep disorders as part of a comprehensive approach to stroke recovery.
Treatment to Improve Sleep Quality
Despite the impact of sleep disorders on patient health, these disorders often remain unrecognized and inadequately managed, leading to worse recovery outcomes. Therefore, addressing PSSD through appropriate therapeutic strategies is crucial. Available therapeutic approaches include pharmacological and non-pharmacological interventions. Pharmacological interventions typically involve medications such as benzodiazepines, non-benzodiazepine sleep medications, melatonin receptor agonists, and sedative antidepressants.
However, long-term use of these medications can lead to multiple side effects, drug dependence, and withdrawal reactions. Thus, it is essential to seek safe and effective non-pharmacological treatments for patients suffering from PSSD. Non-pharmacological therapies include cognitive behavioral therapy, light therapy, acupuncture, traditional Chinese medicine, and non-invasive brain stimulation.
Cognitive behavioral therapy for insomnia, which is the preferred first-line approach for non-pharmacological treatment, faces challenges in scaling due to a shortage of therapists and economic constraints. While the internet opens new avenues in terms of promotional campaigns at low costs, improving the standards and personalization of digital therapies still needs development. In the same context, acupuncture and traditional Chinese medicine have limitations, as their effectiveness may vary based on the skills and practices of the practitioners.
Non-Invasive Brain Stimulation as Treatment
Non-invasive brain stimulation (NIBS) has garnered interest as a promising treatment for PSSD, particularly due to its capacity to enhance neuroplasticity, which is critical for functional recovery. Emerging evidence suggests that NIBS, by targeting neural circuits, can stimulate synaptic plasticity, reorganize neural networks, and optimize sleep architecture, making it a valuable tool in addressing PSSD. Studies have shown that NIBS can modulate cortical excitability, such that transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) can reduce cortical excitation, increase deep sleep duration, and improve overall sleep quality in stroke patients.
Non-invasive brain stimulation techniques include transcranial electrical stimulation (TES) and TMS. TMS involves the use of Faraday’s law of electromagnetic induction, where magnetic coils produce a pulsed magnetic field that penetrates the skin and skull without affecting the approach, reaching the cerebral cortex. TMS can modulate excitability and plasticity in targeted areas, affecting neuronal activity and enhancing neurotransmitter release.
Both TMS and TES show significant improvements in sleep quality, and studies have also demonstrated that brain network stimulation can influence melatonin levels and regulate neurotransmitter levels, contributing to the maintenance of natural sleep cycles. Results related to improved sleep quality in patients who have had strokes are promising indicators that NIBS may be one of the key future treatment strategies worth further research and development.
Future Research Challenges in Treating Sleep Disorders
Despite promising results, it should not be overlooked that current research on NIBS remains limited in terms of sample size, varying inclusion criteria, and heterogeneous methodologies, making the evidence inconclusive regarding its efficacy and safety. Therefore, it is strategic to consider larger cohorts and more cohesive experimental designs to ensure that study results are consistent and generalizable.
Exploring the efficacy of NIBS as a treatment for PSSD requires a better understanding of the relationship between sleep and neuroplasticity. Future research should focus on evaluating the impact of various treatments on neural circuit activation to improve functional recovery rates post-stroke. Additionally, a deeper understanding of the potential side effects of these treatment strategies is critical to ensuring safe and effective options for patients.
For this
The purpose is to better assess the relationship between NIBS and sleep disorders in upcoming studies by identifying the underlying neurophysiological mechanisms, effects of non-pharmacological treatments, and potential associated risks. These research directions gain particular importance when it comes to developing the healthcare system and comprehensive management of patients after stroke, leading to improved clinical outcomes and quality of life.
Inclusion and Exclusion Criteria
The inclusion and exclusion criteria in any scientific studies involve a meticulous process beginning with reviewing titles and abstracts to identify suitable studies. This is essential to ensure the exclusion of duplicate data and to conduct a thorough screening of the existing data. At this stage, inclusivity and accuracy are verified by engaging directly with the original authors of the studies to obtain additional information if necessary, especially in cases of missing data. This procedure is effective in enhancing the reliability of the data included in the final analysis. Studies that did not sufficiently present data or had inadequate information were carefully excluded after exhaustive efforts to obtain the necessary information. Most often, the presence of two researchers working together to develop standardized criteria is beneficial for eliminating bias and ensuring study accuracy. To confirm the validity of these procedures, a third party was involved in cases of dispute to provide an unbiased assessment.
Quality Assessment
The issue of quality assessment is a fundamental point to consider during the literature review. A specific study used the risk assessment tool recommended by the Cochrane Collaboration, which focuses on evaluating six different areas of bias. These areas include selection bias, performance bias, detection bias, attrition bias, reporting bias, and other biases. Each area was classified according to the level of associated risk as “high risk,” “low risk,” or “unclear.” These practices reflect the extent of verification and confirmation that has been carried out to ensure that the included studies were of high quality providing reliable information. There is no doubt that the presence of two researchers working together to form evidence-based opinions on the risks surrounding each study is of great importance in this context, keeping in mind the possibilities for open discussion to resolve any disagreements.
Statistical Analysis
The statistical analysis of the studied studies was conducted using RevMan 5.4, where outcome indicators from the studies were processed using weighted mean differences (MD) for continuous outcomes and relative risk (RR) for dichotomous outcomes. The significance of this data was based on applying a 95% confidence interval (95%CI) with a significance level of α = 0.05. These criteria are integral to the experiment, as a specific format is utilized to produce detailed and realistic results.
Among the materials necessary for evaluating the variance between studies, the Cochran Q test was applied, and I2 statistics were used. In the absence of significant variance (Q test p > 0.1, I2 < 50%), a fixed-effects model was used. In cases of significant variance (Q test p ≤ 0.1, I2 ≥ 50%), the implementation of a random-effects model was required. This systematic approach contributes to uncovering multiple facets of variance and enhances the accuracy of results. Stata 14 was also used for bias-related assessments and conducting sensitivity analyses and subgroup analyses to uncover sources of variance.
Analysis Results
The results obtained from a comprehensive study included a collection of points from 952 articles, with 412 duplicate articles excluded, leading to a final analysis that included 18 studies representing 1482 patients. This figure represents significant evidence of the ability to apply common results from large data sets. The included studies varied between multicenter trials and studies using different techniques such as NIBS, tDCS, TBS, and rTMS, adding depth to the analysis results. Different stimulation methods were also employed, including both low-frequency and high-frequency stimulation, where specific areas of the brain (such as the dorsolateral prefrontal cortex) were commonly targeted for stimulation.
This analysis reflects the improvement in sleep quality indices through the use of tools like the PSQI. Studies balanced between the use of various therapeutic methods and comparisons between NIBS and traditional medical treatments showed a noticeable trend towards significantly positive outcomes.
Assessment
Quality and Final Results
Overall, 18 studies were able to determine how non-surgical stimulation affects sleep quality, calling for the necessity of more studies to enhance the evidence. Part of the overall findings reveals clear comprehensive reports on the effects that can occur and the differences that may affect sleep quality, especially with PSQI indicators. Data were also analyzed using sleep monitoring and various sleep value assessments. These results are significant as they highlight the potential use of NIBS as an effective tool for improving sleep quality in patients.
Undoubtedly, these results will shape future directions which may include the development of clinical applications for this stimulation; if future studies can assist us in documenting these results further, the potential benefits may extend to cover a wide range of clinical treatments in psychological research and clinical guidelines.
Fixed Effect Model and Random Effect Model
During the implementation of statistical analyses regarding the effect of transcranial magnetic stimulation (TMS) on sleep factors, a fixed effect model was used when the level of variance between studies was low. However, it was found that the variance of some other parameters did not decrease significantly, prompting researchers to apply a random effect model. When analyzing sleep parameters unrelated to REM sleep, the results indicate that excluding studies with high bias did not significantly affect the remaining meta-analysis outcomes. Thus, the results were generally reliable, reflecting their stability. However, the study by Sheng et al. was excluded, as the results regarding the REM sleep parameter showed significant changes. This study emerged as a sensitive element in maintaining variance due to the large differences in the percentage of REM sleep between the experimental and control groups. Such differences may be attributed to the alternating stimulation pattern and the high and low frequencies used in Sheng’s study, which necessitates cautious interpretation of the results.
Analysis of Secondary Results and Their Impact on Datasets
The HAMD-17 scores were evaluated in five randomized controlled trials. In one of these studies, the data were not normally distributed, preventing accurate extraction of the mean and standard deviation, which hindered their inclusion in the meta-analysis. However, when examining the remaining four studies, significant variance in the results was found, leading to reliance on a random effect model. The meta-analysis results showed that HAMD-17 scores in the NIBS group were significantly lower than in the control group. It is noteworthy that sensitivity analysis after excluding the Dong study proved that the variance between studies became minimal, ensuring the reliability of the results and adding significant value to clinical evidence. Furthermore, various subgroup analyses showed that HAMD-17 scores were significantly lower in the rTMS and tDCS groups compared to the control group. This analysis demonstrates how transcranial stimulation techniques can contribute to improving the management of depression associated with sleep disorders.
Negative Factors and Side Effects of NIBS Techniques
When studying side effects, a number of occurrences were reported in the studies. The results showed that the rate of adverse effects in the NIBS group was much lower than that in the control group.
