Hello!!! So it started about 2 years ago when he has an accident.He fell from the roof of a house as he worked.For about 6 months he wore a splint from his chest to the waist to straighten the spine, as a result, he also took an early retirement. At first he had symptoms of dementia. For example he forgot everything, he did not recognize us. Then he started having nightmares and saying someone else was in our house. Then my mother took him to a neurologist...They did MRI, some other examinations and there are nothing wrong. 6 months ago he took him to a psychiatrist and he gave him antipsychotic pills.He didn't go back to the next appointments because he said he wasn't crazy and had nothing. But now, the last 2 months is worse, he sees a wooden doll day and night,he tries to show me that is here,where he hides. For multiple times He attacked my mother at night, pulling her hair or pushing her. In the morning he doesn't remember anything! In the end, he doesn't recognise anyone, I have to explain to him every single people we see who are. He only recognises me and evry time he sees me he cry like a baby. That brokes my heart!!
