Background: Despite affecting 2-4% of the population worldwide, fibromyalgia often remains refractory to treatment. Here we report the first international randomised double-blind, sham-controlled trial developed to assess the efficacy of repetitive transcranial magnetic stimulation (rTMS) as an add-on therapy for fibromyalgia.
Methods: Women aged ≥18 yr with fibromyalgia refractory to best available treatment were enrolled in Brazil, France, and Japan, and randomised to 10 Hz motor cortex (M1) rTMS, 3000 pulses day, or sham stimulation.
Importance: Intermittent theta-burst stimulation (iTBS) is an established treatment for treatment-resistant depression (TRD). Sessions conducted more than once daily (ie, accelerated TBS [aTBS]) may enhance antidepressant effects. However, evidence is limited to small trials, and protocols are time-consuming and can require neuroimaging-based targeting.

While transcranial direct current stimulation (tDCS) is an effective treatment, its impact on symptoms remains underexplored. This ancillary study investigated home-use tDCS effects on depression symptom clusters.

They exerted preferable efficacy and had been considered as an alternative or add-on treatment to the traditional pharmacotherapy. However, the risk of complication of seizure had seized the clinicians so that they feared about this potential complication.

Transcranial Direct Current Stimulation (tDCS) has shown promise in improving cognitive performance in stroke patients. We explored the effects of tDCS on cognitive performance in PSD.

Attempts to enhance it using transcranial direct current stimulation (tDCS) have shown mixed results, possibly due to large inter-individual variability. This study assessed whether baseline regional brain volume was associated with working memory performance following tDCS.
View Article and Find Full Text PDFBackground: Magnetic seizure therapy (MST) has emerged as a promising alternative to electroconvulsive therapy (ECT) for treatment-resistant depression. Previous systematic reviews and meta analysis already showed its primary results, however, there are no recent reviews updating these findings.
Objectives: This systematic review aimed to make an updated systematic review of MST on unipolar and bipolar depression.
Objective: To identify the COVID-19 pandemic impact on well-being/mental health, coping strategies, and risk factors in adolescents worldwide.
Method: This study was based on an anonymous online multi-national/multi-language survey in the general population (representative/weighted non-representative samples, 14-17 years of age), measuring change in well-being (World Health Organization-Five Well-Being Index [WHO-5]/range = 0-100) and psychopathology (validated composite P-score/range = 0-100), WHO-5 <50 and <29, pre- vs during COVID-19 pandemic (April 26, 2020-June 26, 2022). Coping strategies and 9 a priori- defined individual/cumulative risk factors were measured.
Background: While loneliness is a global public health problem, the literature lacks studies assessing loneliness predictors in low- and middle-income countries. Therefore, we aimed to analyze clinical and lifestyle predictors of loneliness.
Methods: We conducted a 2-year longitudinal study in Brazil based on a snowball sample and online surveys (baseline: May 6 to June 6, 2020).
Headache
November 2024
Background: While headache disorders are linked to low physical activity levels, the impact of depression on this relationship is unclear.
Objective: To assess how single and comorbid diagnoses of migraine and tension-type headache (TTH) interact with depression and leisure-time physical activity (LTPA) levels in The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).
Methods: In this cross-sectional analysis based on the ELSA-Brasil baseline data, the relationship of migraine, TTH (both assessed with the International Classification of Headache Disorders, Second Edition), and depression (assessed with the Clinical Interview Schedule-Revised) with LTPA levels (International Physical Activity Questionnaire) was investigated by employing linear regression models.
Background/objectives: Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation intervention that shows promise as a potential treatment for depression. However, the clinical efficacy of tDCS varies, possibly due to individual differences in head anatomy affecting tDCS dosage. While functional changes in brain activity are more commonly reported in major depressive disorder (MDD), some studies suggest that subtle macroscopic structural differences, such as cortical thickness or brain volume reductions, may occur in MDD and could influence tDCS electric field (E-field) distributions.

Background: Ultraprocessed foods (UPF) consumption has been associated with depression risk, but its association with depression persistence is unclear.
Objective: The objective of this study was to evaluate the association of UPF consumption with depression persistence and incidence.
Design: The Brazilian Longitudinal Study of Adult Health is a multicenter prospective cohort study with 3 waves (2008-2010, 2012-2014, and 2017-2019).
Objective: Gender differences may interfere with the association between Negative Life Events (NLEs) and prevalent/incident depression. This study evaluated the effect of gender in this association using data from the ELSA-Brazil cohort.
Methods: The authors analyzed 15,088 participants (mean age, 52.
Transcranial magnetic stimulation (TMS) represents a distinctive technique for non-invasive brain stimulation. Recent advancements in image processing have enabled the enhancement of TMS by integrating magnetic resonance imaging (MRI) modalities with TMS via a neuronavigation system. The aim of this study is to assess the efficacy of navigated TMS for cortical mapping in comparison to surgical mapping using direct electrical stimulation (DES).

Methods: Data were collected between July 2020 and June 2021 (N = 1,078). Anxiety, depression, and posttraumatic stress symptoms were assessed using three self-report scales (GAD-7, PHQ-9, IES-R).
Background: There is scarce data concerning the relationship between negative life events (NLEs)* and current and new depressive episodes by age.
Methods: Cross-sectional (baseline) and prospective analyses (4-year/8-year follow-ups) were performed in 15,105 civil servants in 6 cities in Brazil classified according to age strata at baseline: 1st(35-44), 2nd(45-54), 3rd(55-64), and 4th(65-74) years. The independent variable was NLEs in the last year (robbery, hospitalization, death of a relative, financial hardship, and rupture of a love relationship) collected at baseline.

Background: Home-based transcranial direct current stimulation (Hb-tDCS) is a non-invasive brain stimulation technique that utilizes low-intensity electric currents delivered via scalp electrodes to modulate brain activity. It holds significant promise for addressing inattention in adults with attention-deficit/hyperactivity disorder (ADHD). However, its effectiveness varies among individuals, and predicting outcomes remains uncertain, partially due to the influence of individual differences in ADHD-related brain anatomy.
