Unlocking Therapeutic Potential: The Role of Theta Burst Stimulation in Multiple Sclerosis Management.

Objective: Current therapies for multiple sclerosis (MS) often have limited efficacy and side effects, necessitating alternative approaches. Noninvasive brain stimulation (NIBS), such as transcranial direct current stimulation and transcranial magnetic stimulation (TMS), offers potential solutions. Among NIBS techniques, theta burst stimulation (TBS) is notable for its ability to modulate cortical activity. The objective of this systematic review is to assess the impact of TBS on MS symptoms.Data Sources: The study conducted rigorous systematic searches in PubMed, Google Scholar, and Scopus databases up to June 2023, using specific Medical Subject Headings terms related to NIBS and MS, such as TMS and TBS, in conjunction with terms like MS or demyelinating disease. Additionally, the bibliographic references of included studies, book chapters, and original articles were manually reviewed.Study Selection: The study selection process involved a 2-tiered screening mechanism, beginning with an evaluation of titles and abstracts, followed by a full-text review of selected articles. Inclusion criteria incorporated randomized controlled trials (RCTs) focusing on TBS with MS patients. Exclusion criteria included non-qualitative, non-MS, and non-TBS studies. Risk of bias assessment was conducted using the 2008 Cochrane Risk of Bias 2 Scale for RCTs.Data Extraction: Data extraction was conducted by thoroughly reviewing each research article and systematically recording the relevant information using a standardized data extraction form, ensuring consistency and accuracy throughout the process.Results: In a systematic review encompassing 5 randomized controlled trials involving 117 individuals with relapsing-remitting or secondary progressive MS across Italy, France, and Russia, various forms of TBS were applied. These interventions ranged from intermittent TBS (iTBS) to continuous intermittent TBS (c-iTBS) that demonstrated favorable outcomes. Notably, TBS interventions led to significant reductions in spasticity, fatigue, and pain, with c-iTBS combined with vestibular rehabilitation showing additional improvements in vestibular-ocular reflexes, gait, and balance. While specific protocols varied among the studies, collectively, the results suggest promise for TBS approaches in alleviating MS-related symptoms.Conclusions: The findings of this review suggest that TBS may hold promise in addressing specific MS symptoms, notably fatigue and spasticity. Future research should include a more diverse participant pool to explore TBS effects across different MS subtypes and aim for larger sample sizes to enhance statistical power and result reliability.Prim Care Companion CNS Disord 2024;26(2):23r03645.

Association of Body Dysmorphic-Induced Anabolic-Androgenic Steroid Use With Mental Health Outcomes: A Systematic Review.

Objective: To explore the relationship between body dysmorphic disorder (BDD), anabolic-androgenic steroid use (AAS) use, and mental health outcomes and to identify potential interventions and treatments that may help mitigate these detrimental effects.Data Sources: PubMed, Scopus, CINAHL, Embase, and PsycINFO were searched from 1992 to 2022 with no language limits. Search terms included "AAS" AND "mental health outcomes" AND "body dysmorphia" and were expanded in PubMed to include "anabolic steroids induced depression," "anabolic steroids induced depression in athletes," "steroids," "mental health," and "performance-enhancing drugs."Study Selection: Forty-one articles were identified, and 37 remained after duplicates were removed. After full-text appraisal, 33 articles were included in the final review.Data Extraction: Two reviewers independently screened studies for inclusion criteria, extracted pertinent data, and assessed the quality of evidence.Results: Bodybuilders and fitness athletes may be more susceptible to developing muscle dysmorphia, having disordered eating habits, and using performance-enhancing drugs like AAS. The COVID-19 pandemic increased reliance on social media and online interactions, which was previously associated with disordered eating patterns and negative body image. Being a member of a sexual minority may increase one's risk of developing muscle dysmorphia and other types of BDD, as these individuals may experience additional stressors and difficulties due to stigma and discrimination, which may worsen one's sense of self and body image.Conclusion: The development and evaluation of interventions such as cognitive-behavioral therapy, mindfulness-based interventions, and peer support programs, should be prioritized to deter AAS use in people at risk.Prim Care Companion CNS Disord 2023;25(5):23r03532.
