### input:
My mom is 85 and declining rapidly with no short term memory. I am her live-in, full time caregiver, bt in the last month she has become obsessive, (lost her sunglasses a month ago and I discuss it 15 hours a day with her). She gets agitated easily and angry with me, she knows Im doing everything to help her but think the restaurant she was at a month ago has them. Ive driven her there three times, shes sure that they call her every night and wants me to pick them up. Shes driving these poor people nuts. I go through it about firty times a day, she wakes me at midnight, I hide in the am until Im ready to start another day in paradise. Its the rapid increase in the dementia that  is my concern. Had her at a neurologist last week twice, she doesnt want to see any more drs. She had od on Aricept in March(?) after 5 days on it, was hospitalized four day later because I had been counting them, much to her dismay, lost all her electrolytes and was very sick. They put her on a low dose Exelon patch which I used for two months but she just kept getting worse. Theneurologit put her on Namenda last week an will treat her for Parkinsons after she is established on the Namenda. Id prefer giving her Atavan or something to calm her down. The depression is a new symptom and she hates living this way.  She wants to maintain control over herself and I understand, I help if she asks while I sit there quietly. Im living in hell with her and her body is much stronger than mine. I smashed my patella 8 mos ago and never healed properly because Ive always take care of everything here Do you think there is any med out there to help relieve her obsessiveness and extreme anxiety and unhappiness without kowing her specifics?.
