Luckyirl , my OH has PD and related dementia , but he just tries to ring neighbours and sell cattle !! Yesterday he was convinced he was in Australia , it is usually related to something he overhears or sees on TV . There is no way I can keep his condition from my Children . Another point is he is much worse and very agitated when he has a UTI . This can be really bad , so now he is on permanent antibiotics . It is so wearing to have to keep reassuring him that he is home in his own house and to not have a sensible conversation , the delusions you mention can be the side effect of one of the tablets , OH took up gambling not the side effect I think you mean !! sadly he is chairbound and can no longer work the phone or the computer or we would be broke !! , you do have to laugh or you would spend the day in tears .Please confide in someone , you cannot bear this alone , the children might not be as shocked as you think
