Quantitative electroencephalography (qEEG) data can facilitate the monitoring of treatment progress and the evaluation of therapeutic responses in patients with Major Depressive Disorder (MDD). This study aims to compare the qEEG data of MDD patients and healthy controls, both before and after treatment, to assess the effect of treatment response on neural activity. A total of 72 patients, aged 18-60, who had not used any psychopharmacological medication for at least two weeks, were included in the study.

Article Synopsis
  • - This study aimed to explore how having nocturnal enuresis (NE) during childhood affects the development of overactive bladder (OAB) later in life.
  • - Researchers gathered data from 103 patients with OAB symptoms, noting their backgrounds and conducting assessments on urinary habits and bladder function.
  • - Findings suggest that individuals with a history of NE in childhood tend to experience OAB symptoms earlier and more severely, indicating that NE could potentially be a contributing factor to developing OAB.

Previous studies revealed that rapid eye movement (REM) parameters, such as REM latency (RL) and REM density (RD) could be used as electrophysiological markers of depression. Yet these finding should be re-tested in a comorbid-free and drug-free sample. The present systematic review and meta-analysis was conducted to investigate whether drug-free and comorbid-free patients with unipolar depression differentiate from controls with respect to the RL and RD.

  • Deep Transcranial Magnetic Stimulation (dTMS) is an FDA-approved non-invasive therapy that effectively treats depression and OCD.* -
  • A study involving 29 OCD patients found that after 30 sessions of dTMS, all participants showed at least a 35% reduction in OCD symptoms, measured by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).* -
  • QEEG data indicated significant decreases in theta, alpha, and beta brain rhythms, with the reduction in OCD severity linked to decreased beta activity, suggesting dTMS may alter brain oscillations related to treatment response.*

  • Skin picking disorder (SPD) involves compulsive skin scratching without a primary skin condition and is often linked to psychiatric issues like OCD and depression.
  • A case study of a 32-year-old woman with SPD shows that after a four-week paroxetine treatment, her OCD symptoms reduced significantly, and her skin lesions healed completely, with only minor discoloration remaining.
  • The study suggests that treating SPD when associated with OCD and abnormal EEG readings can lead to successful outcomes with paroxetine, indicating a need for further research in this area.
