ABSTRACT
Deep transcranial magnetic stimulation (dTMS) is an Food and Drug Administration-approved treatment for treatment-resistant depression (TRD). Our study aims to examine the impact of baseline insomnia severity on mood outcomes of dTMS and the impact of dTMS on comorbid insomnia in patients with treatment-resistant depression using a retrospective analysis. Twenty-five patients with treatment-resistant depression who underwent dTMS were divided into two groups: "low insomnia" and "high insomnia," depending on Insomnia Severity Index scores at baseline. Significant improvements in depression and anxiety from baseline to final dTMS session were noted in both groups. Baseline insomnia severity was not associated with poorer treatment outcomes after dTMS. Final insomnia scores of the two groups were not significantly different, suggesting dTMS alleviated insomnia symptoms in patients with treatment-resistant depression. Further research incorporating a prospective study design in a multicenter setting is warranted to replicate these findings and elucidate the mechanistic action of dTMS on insomnia outcomes.

Somatic Symptom disorders (SSDs) are characterised by the presence of persistent somatic symptoms associated with excessive thoughts, feelings and behaviours related to the symptoms. However, current treatment modalities are non-specific with modest effects. We aim to explore the safety and outcome of high-frequency transcranial magnetic stimulation at medial Prefrontal Cortex in ten such patients. Patient Health Questionnaire-15, Hamilton Rating Scale for Depression and Hamilton Anxiety Rating Scale were applied to ten patients with Somatic Symptom Disorder. 15 sessions of 15Hz TMS using a double cone coil with 2500 pulses/session were administered. All patients completed their sessions except one. Eight of the nine patients reported significant improvement with a reduction of 33%-80% from their baseline PHQ-15 scores. One patient reported significant adverse effects. Double cone coil TMS at medial Prefrontal Cortex appears to be a safe therapeutic intervention with potentially good outcomes in SSDs.
ABSTRACT
To raise awareness of attention-deficit/hyperactivity disorder (ADHD) as an underdiagnosed, undertreated disorder in adult patients with comorbid substance use disorder (SUD) who are misdiagnosed with other common psychiatric illnesses and to reduce fear and hesitancy in prescribing stimulants as treatment in such a patient population. ADHD diagnosis is easier in the child and adolescent population than the adults due to comorbidities of other psychiatric illnesses and SUD. However, diagnosing ADHD appropriately in an increasing number of adult patients presents challenges. Even if they get diagnosed appropriately, the stigma of substance use disorder holds the providers prescribing stimulant medications for such patient populations due to the high comorbidity of ADHD with SUD. Accurate diagnosis of ADHD in adults is a worthwhile endeavor as this diagnosis is comorbidly present in many mood and substance use disorders patients. Treating ADHD in this population can improve clinical symptoms and overall quality of life.
ABSTRACT
Background: The nosological tradition in psychiatry defines diagnostic criteria for disorders based on expert consensus than objective biological markers reflecting underlying neurobiological correlates. Endophenotypes have been researched as heritable biological markers that can be quantified and defined to represent intermediate measures of a psychiatric illness. In obsessive-compulsive disorder (OCD), various putative biomarkers such as neuropsychological, neurophysiological, neuroradiological, brain-derived neurotrophic factor (BDNF), etc., have been explored. Aim: The study aimed to compare levels of serum BDNF in individuals with OCD and their unaffected first-degree relatives (FDR) with healthy controls (HC). Methods: This cross-sectional study compared serum BDNF levels in medication-free/naive individuals with OCD (n = 30) to their FDR (n = 30) and age-sex matched HC (n = 30). Intergroup comparison was done using analysis of variance (ANOVA) and post-hoc Tukey's test. Correlation analysis was conducted to find the relationship of sociodemographic and clinical correlates to serum BDNF as well as dimensional subtypes of OCD. Results: No significant difference in BDNF levels was observed between OCD and HC (P = 0.13) but a significantly higher level was found in the FDR group compared to age-sex matched HC (P = 0.02). Conclusion: BDNF levels may have a complex interplay influencing the genetic inheritance and clinical manifestations of OCD. Further research is required before considering it a viable biomarker.
ABSTRACT
Clonidine, an alpha-2 adrenergic agonist, has been proposed as an antimanic agent that acts by reducing noradrenergic transmission. We conducted a systematic review to examine the efficacy and safety of clonidine for acute mania/hypomania. A comprehensive literature search was performed to identify randomized controlled trials (RCT) and non-randomized studies investigating the efficacy and safety of monotherapy/adjuvant treatment with clonidine for acute mania/hypomania in patients with bipolar disorder (BD). Nine studies (n = 222) met our inclusion criteria, including five RCTs (n = 159) and four non-randomized studies (n = 63). Non-randomized studies showed clonidine to help reduce symptoms of mania. However, data from placebo controlled RCTs were inconsistent. One RCT showed adjuvant clonidine as superior to placebo, whereas another RCT reported that clonidine was not better than placebo. In individual RCTs, lithium and valproate offered better antimanic effects compared to clonidine. Studies reported hypotension, depression, and somnolence as common adverse effects. Significant differences in study design and sample size contributed to high heterogeneity. This systematic review suggests low-grade evidence for clonidine as an adjuvant treatment for acute mania with mood stabilizers and inconclusive efficacy as monotherapy, warranting further well-designed RCTs.
ABSTRACT
OBJECTIVE: This review aims to synthesize and critically evaluate the existing literature on kratom use and its possible association with induction of psychotic and manic symptoms, in order to identify potential areas for future research that would improve our understanding of the risks of kratom consumption. METHODS: An electronic search was performed using five major databases: including PubMed, Scopus, Google Scholar, Web of Science, and PsycINFO. keywords such as kratom, Mitragyna speciosa, mania, psychosis, bipolar disorder, schizophrenia, schizoaffective, case report, and case series. The retrieved articles on initial search were screened based on predefined inclusion and exclusion criteria for this study, and then data synthesis was performed to analyze relevant information from the included studies. RESULTS: Six prior papers were found using (1 case series and 5 case reports). These included 10 cases, involving kratom use association with mania and psychosis. The ages of patients ranged from 28 to 55 years mean age was 38, and (SD 13.74), the majority were males (8 out of 11). Patients had durations of kratom use ranging from 2 wk to 15 years. Significant association was found between kratom use and the worsening of psychotic and manic symptoms in individuals with psychiatric conditions. CONCLUSIONS: Our research highlights the possibility of worsening preexisting psychiatric conditions in the context of kratom use. This study emphasizes the need for clinical evaluation of patients for kratom use. Additional research is required to gain a deeper understanding of the potential mental health implications of kratom use, especially among vulnerable populations.
