Depresia, legată de reducerea unei zone-cheie a creierului. Descoperirea ar putea explica legătura cu demența

A recent study reveals that individuals with depression have a smaller volume in a specific hippocampal region, potentially linking depression to cognitive decline and Alzheimer's disease. The research analyzed brain scans of over 2,000 adults aged 50 to 90, finding that those with depression exhibited reduced volume in the CA23DG region, crucial for memory. This association persisted even after accounting for various factors. The study suggests that the duration of depression may impact structural changes in the hippocampus more than the severity of symptoms. However, the observational nature of the study means causality cannot be established, and further research is needed to explore these relationships.
