Mom went to rehab (6wks) started drinking again soon after. Has made questionable financial decisions, also sexually uninhibited, Has gone to several therapists but stops after a few visits, She is not like this all the time, Much of the time she is lucid, rational and a delight to be with, but she frequently gets confused, extremely emotional, and angry. It's at these times she takes off in the car and endangers her life and others. It's like a roller coaster. Is it alcoholism, dementia or both?
