I have recently seen real improvement in my husband's so-called dementia, as three different doctors told me he had. An adjustment in meds and addition of a good anti-depressant has given us both a normal life again. It appears that his supposed dementia was medication induced. He had extreme surgery ten years ago in which his esophagus and 2/3 of his stomach removed. He has been on pain meds and anxiety meds ever since: Tramadol and Clonazepam. The dose of the latter was reduced and Mirtazapam added. The change was almost overnight.
