Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by problems with inattention, hyperactivity, and impulsivity. While ADHD has historically been considered a disorder of childhood, it is now known that symptoms frequently persist into adulthood. A new pilot study published in the Journal of Clinical Psychiatry provides the first data indicating that a newer …
Advanced analysis of multidimensional EEG data reveals significant differences in brain activity patterns between Generalized Anxiety Disorder (GAD) and Depressive Disorder (DD). The distinguishing factors seem to be differences in beta brain waves and functional connectivity between various brain regions. Key Facts: Patients with DD exhibited higher power spectrum density (PSD) values and fuzzy entropy …
A new study provides promising evidence that delivering transcranial direct current stimulation (tDCS) remotely in people’s homes could be an effective treatment approach for major depressive disorder. The key facts are: tDCS is a form of non-invasive brain stimulation that uses electrical currents to modulate activity in targeted brain regions. When applied to the left …
New research suggests a U-shaped relationship between dietary niacin and depression risk, with the lowest risk around 36 mg/day. Key Facts: Moderate niacin intake was associated with a 24-32% lower odds of depression compared to the lowest intake. The relationship was U-shaped – higher and lower intakes were associated with higher depression risk. 36 mg/day …
A study suggests that mindfulness training can not only improve mindfulness, but also make functional brain reconfiguration more efficient in older adults with sleep issues. Mindfulness training enhanced measures of “mindfulness” (i.e. the quality or state of being conscious or aware) as well as functional brain connectivity patterns – relative to a control intervention. Key …
Researchers have uncovered a critical role for the metabolic enzyme acetyl-CoA synthetase short-chain family member 2 (ACSS2) in depression, identifying it as a novel target for rapid-acting and long-lasting antidepressant therapies. Findings show ACSS2 regulates both brain-derived neurotrophic factor (BDNF) levels to improve synaptic plasticity and serotonin synthesis through tryptophan hydroxylase 2 (TPH2) to mediate …
A new study published in Translational Psychiatry found evidence that genetic predisposition to depression is associated with increased risks of 12 different gastrointestinal diseases, including irritable bowel syndrome, non-alcoholic fatty liver disease, gastroesophageal reflux disease, ulcerative colitis, and more. The study helps establish a causal relationship between depression and gastrointestinal disease risk while minimizing confounding …
