Abstract

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) symptoms have been linked to suicidal behavior. However, little is known about the mechanisms involved in this association. This study examined ADHD symptoms and suicidal ideation during the COVID-19 pandemic and the role of self-perceived stress in this association. METHOD: Data were analyzed from an online sample of 1,452 Japanese individuals aged 18 to 89 obtained in February 2021. Information was collected on past-year suicidal ideation. ADHD symptoms were assessed with the Adult ADHD Self-Report Scale (ASRS) Screener while stress was measured with the Perceived Stress Scale (PSS-14). Depressive symptoms were assessed with the Patient Health Questionnaire (PHQ-9), while the Generalized Anxiety Disorder scale (GAD-7) was used to assess anxiety symptoms. Logistic regression was used to examine associations. RESULTS: Fifty-one (3.5%) individuals had ADHD symptoms, while more than one in ten (11.7%) of the respondents reported past-year suicidal ideation. In an analysis adjusted for sociodemographic factors, ADHD symptoms were associated with eight times higher odds for past-year suicidal ideation. However, adjusting the analysis for mental health variables (anxiety and depressive symptoms) attenuated the association which became non-significant (odds ratio [OR]: 1.96, 95% confidence interval [CI]: 0.92-4.18). In contrast, in an analysis adjusted for mental health, individuals with ADHD symptoms and stress had significantly higher odds for suicidal ideation (OR: 3.72, 95%CI: 1.43-9.67) whereas, ADHD symptoms without stress were not linked to suicidal ideation (OR: 1.25, 95%CI: 0.38-4.18). CONCLUSIONS: Self-perceived stress is important in the association between ADHD symptoms and suicidal ideation among individuals in Japan during the COVID-19 pandemic. Detecting and managing stress and its effects in individuals with ADHD/ADHD symptoms should be a therapeutic focus for improving health-related outcomes in t

28. A Meta-Analysis of the Effect of Multisession Transcranial Direct Current Stimulation on Cognition in Dementia and Mild Cognitive Impairment

Abstract

There have been increasing efforts to investigate the effects of neuromodulation techniques, such as transcranial direct current stimulation (tDCS), on cognitive impairment in dementia and related conditions. In this systematic review and meta-analysis, we assessed the efficacy of multisession anodal tDCS compared with sham stimulation for improving global cognition and specific cognitive domains in both Alzheimer's disease and mild cognitive impairment. Eight articles meeting the criteria for inclusion in the meta-analysis were selected. Five studies used the Mini-Mental State Examination to examine mild cognitive impairment and dementia. In a fixed-effect model, there was a mean difference in the change score of -0.13 points. Three trials for dementia using the Alzheimer's Disease Assessment Scale-Cognition showed a mean difference of -0.53 points. At present, there is a lack of clear evidence concerning the efficacy of multisession anodal tDCS due to the small number of studies and different measures used. This underscores the need for further investigations using larger samples and common outcome measures.

Abstract

Aims: This systematic review aimed to evaluate randomized controlled trials (RCTs) to examine the effect of maternal and infant sleep intervention during women's pregnancy for the purpose of preventing perinatal depression. Method: A systematic search (from inception to January 28, 2019) for RCTs using five electronic databases—the Cochrane Controlled Register of Trials (CENTRAL), Embase, PubMed, PsycINFO, and Ichushi Web (Japan Medical Abstracts Society)—was conducted. Twelve investigators independently conducted initial screenings based on title and abstract, and then, two researchers performed full‐text reviews one by one. A meta‐analysis would be conducted if at least three studies were found. However, only two articles that met inclusion criteria, and narrative data synthesis was conducted for these two articles. The study protocol has been registered at PROSPERO (CRD42019119999). Result: A total of 13 654 studies were initially searched. After removing duplicates, 10 547 studies were screened, and finally, two studies met the inclusion criteria. In both studies, the intervention was a one‐time face‐to‐face session during pregnancy to deliver the behavioral knowledge and skills for optimizing sleep hygiene for both infant and mother. Effectiveness of the intervention in improving maternal mood was not significant in one study. In the other, there was a significant difference in maternal mood between the intervention and control group. No mood comparison was made between baseline and postintervention. Conclusion: This study found limited evidence to support the effectiveness of sleep intervention for all pregnant women, which means "universal intervention," to protect maternal mental health. Further well‐designed RCTs are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Photobiomodulation (PBM) is a novel strategy for cognitive enhancement by improving brain metabolism and blood flow. It is potentially beneficial for patients with Alzheimer's disease (AD). We present a study protocol for a randomised controlled trial designed to evaluate the efficacy and safety of PBM., Method and Analysis: This is a single-centre, parallel-group, randomised, sham-controlled study. We enroll patients with mild cognitive impairment or dementia due to AD and assigned them to receive either active or sham stimulation at home for 12 weeks, with three sessions per week (20 min each). The stimulation involves invisible near-infrared light delivered by five applicators (one in a nostril, one on the frontal scalp, and three on the occipital scalp). The primary outcome will be the mean change in the Alzheimer Disease Assessment Scale-cognition from baseline to Week 12. We will also measure cognitive function, activity of daily living, behavioral and psychological symptoms, and caregiver burden. We will collect data at clinics at baseline and Week 12 and remotely at home. We estimate a sample size of 30 (20 active and 10 sham) based on an expected mean difference of -6.9 and an SD of 4.8. We use linear models for the statistical analysis., Ethics and Dissemination: The National Center of Neurology and Psychiatry Clinical Research Review Board (CRB3200004) approved this study. The results of this study will be published in a scientific peer-reviewed journal.
