My mom has always been a very gentle person. She was almost always soft spoken and rarely cussed. in all of my 43 years I have only heard her use the F word perhaps twice and she didn't even finish saying the word. It is now her new favorite thing to say. She will now tell me to ----- off if i don't agree with what she is saying. My mom is now rude to people in public or on the phone. She has threatened doctors office employees over the phone that she was going to go down to the office and hurt them. My mom and i have always had open communication about sex and intimacy. But, not with too much detail. She is now speaking about sex to everyone she meets. She has talked to my teen (18 and 19 yr old) daughters about her sex life and has offered to purchase them umm lets just say gadgets. She becomes enraged when a conversation is in opposition to her views. Flipping over a kitchen table or throwing her cell phone down on the cement. She has spent all of their money in days and has not paid bills or rent. She will call my home at midnight to chat and not think anything of it. She can tell me a story then leave the room to put her shoes on and when she returns she will tell me the same story as if I had never heard it. My mom was never a drinker. She very rarely had even a glass of wine. She has begun drinking brandy now and will drink a bottle of brandy within a week. My dad doesn't know what to do. He is very concerned! I don't know what to do! We have been to doctors for other health reasons (she has edema issues that she is being tested for) they are running tests but tell us psychologically she is fine. Most of these behaviors are not every day. Her money spending and new obsession with sex is though. Does this sound like typical aging as I am being told or do some of these drastic personality changes sound like something is happening neurologically?
