Some results suggest that depression is associated with hippocampal atrophy, perhaps due to a progressive process mediated by glucocorticoid neurotoxicity.We observe the evidence for hippocampal atrophy in Cushing syndrome, which is characterized by a pathologic oversecretion of glucocorticoids; episodes of repeated and severe major depression, which is often associated with hypersecretion of glucocorticoids; and posttraumatic stress disorder. I hope that left hyppocapus will work and he will not have following up symptoms. We can not treat atrophy. But we should improve his blood circulation in brain by giving of Nootropil, B complex with lysin, multivitamins, exercising.
