Article Synopsis
  • - The study aimed to explore how well people diagnosed with fibromyalgia understand their condition and the effects this knowledge has on their ability to manage the disease.
  • - Conducted in Rio de Janeiro, Brazil, the qualitative research involved interviews with 30 participants, mostly women aged 41 to 60, many of whom were unaware of the disease's name and causes but recognized common symptoms like pain.
  • - Findings highlight that misconceptions about fibromyalgia contribute to stigma and challenges in seeking treatment, with many patients relying on support groups to share their experiences and cope effectively.

Objective: To analyze the effects of transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) on the cognitive function of individuals with Alzheimer's disease (AD).

Methods: This systematic review with meta-analysis and meta-regression included randomized clinical trials published until 05/2022. We included studies conducted with individuals with AD of both sexes, aged between 55 and 85 years, treated with tDCS, TMS, or both.

Naturalistic paradigms are being increasingly applied to investigate human brain function. Compared with resting-state and task-based paradigms in neuroimaging, naturalistic stimuli and situations can be potentially more readily translated to daily-life applications. Among neuroimaging modalities, functional near-infrared spectroscopy (fNIRS) is particularly suitable for naturalistic investigations and applications.

Objectives: We aimed to examine the effects of multisite anodal transcranial direct current stimulation (tDCS) combined with cognitive stimulation (CS) over 2 months on cognitive performance and brain activity, and the relationship between them, in patients with Alzheimer's disease (AD).

Methods: Patients with AD were randomly assigned to an active tDCS+CS (n=18) or a sham tDCS+CS (n=18) group. Cognitive performance was assessed using the Alzheimer Disease Assessment Scale-cognitive subscale (ADAS-cog) and brain activity using EEG (spectral power and coherence analysis) before and after the intervention.
