Question

depression me brain ka kon sa part damage hota hai? sahi batana nhi to pungi baja dunga

Answer 1

Brain damage is caused by persistent depression rather than being a predisposing factor for it, researchers have finally concluded after decades of unconfirmed hypothesising.

A study published in Molecular Psychiatry today has proved once and for all that recurrent depression shrinks the hippocampus - an area of the brain responsible for forming new memories - leading to a loss of emotional and behavioural function.

Hippocampal shrinkage has long been linked to depression but previous studies haven’t been conclusive. Small sample sizes, varying types of depression and treatment levels, as well as variance in methods for collecting and interpreting results, have together led to inconsistent and often conflicting findings.

Now, with the help of what co-author Ian Hickie from the Brain and Mind Research Institute has called “a new spirit of collaboration” a global, cross-sectional analysis of brain scans of 9,000 people has conclusively linked brain damage to depression.
