A chronically under-active thyroid can lead to slowly progressive dementia , delirium , and in extreme cases to hallucinations , coma , or ...
The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 1 ]
