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 …
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 …
Statins are among the most commonly prescribed medications worldwide. While best known for lowering cholesterol, emerging evidence suggests that statin drugs may also impact mental health – but in complex, and sometimes contradictory, ways. Key Facts: Animal and some human studies show statins may have antidepressant effects by altering neurotransmitters, promoting neurogenesis, and reducing inflammation. …
A new study reveals an association between higher dietary acid load and increased risk of depression and anxiety, particularly in women. The research highlights the potential role of diet in mental health and wellbeing. Key Facts: Women with high dietary acid load had 20% higher odds of severe depression compared to those with low acid …
Celecoxib, a selective COX-2 inhibitor, shows promise as an effective and safe adjunct treatment for major depression and mania, according to a new comprehensive systematic review. The analysis also found celecoxib improved symptoms when used as a standalone antidepressant in patients with somatic disorders. However, evidence for efficacy in bipolar depression remains unclear. Key Facts: …
