Hi All, Long time no see. But right now I need the benefit of your experince. Some time ago I posted about mam and her belief that dad was having an affair, (absolutely not true). This week everything blew up. My phone rang, I answered, no-one replied but I could hear mam and dad arguing. Shouting, screaming, threatening. Then the phone went dead.it was all about mam accusing dad of the affair. I rang back, mam asked me to pick her up so I did. She stayed at my house for a few days, refusing to see my dad or speak to him. My brother rang the memory clinic. A cpn and social worker got involved and now she is in a home for 2 weeks. The cpn mentioned "fixed beliefs" and the possibility of medication. She also said they had no record of this problem when I had taken aside the psych and nurse numerous times to tell them about it. Mam and dad are of that generation where private things are just that, private, and it is incredibly difficult to get either of them to talk about it. However this is the root of their difficulties at home. Anyway, I was wondering if anyone else had experience of this and how best to deal with it. Has medication helped? Sorry for the long post but any advice/experiences gratefully received. .
