We (my sisters and I) feel that our other sister has some signs of Alzheimers and/or dementia. The visible symptoms are memory loss: long and short term. Signs of depression; highly emotional. Cries easily. She has an ill husband, a daughter and 3 grandchildren (all under 4) living with her. She recently retired from the work force and assumes most of the parenting responsibilities. She is diabetic. Recently called husband hysterical because she thought she had lost one of the children.What doctor /specialist should we see first to start the diagnosis process?
