My uncle is about 80 years old he has some strange behaviour and nobody can figure out what is wrong. He repeats sentences over and over, he will go into detail how he went to the washroom, or did other daily things. He keeps saying stuff like " do you want me to tell you how i went to the washroom" he goes into detail of the color of something like he says " the brown table brown table brown table" or if he washed dishes he will start talking then seem to get stuck like his brain is skipping "i wiped and i wiped and i wiped"etc. He also thinks he will choke if he eats says he can't shave or eat but he can he just panics... he complains he feels weak and dizzy all the time... he thinks his son is trying to make him drink other peoples beverages and will hit the drink away etc. I am concerned I have never seen this happen to somebody before and I am hoping to find out what might be causing this to happen. Thanks
