Hi, I've just joined TP and rather bewildered by all the info! My husband Rod now has dementia on top of Parkinsons. Its because of the strong medication he is on. The dementia takes the form of obsessive thoughts which are overwhelming him. Its all very scary and I dont know where to go for help. The doctor prescribed a pill which gave him sickness and diarrohea and he is now saying whatever medicine he has may have the same effect so where do we go from here? I dont know what to do to help him. I've read some of the other Threads and you all seem much worse and I am wondering how do you all cope? I think its because this is a new aspect of Rod's illness that I am frightened of the future. I have been coping with his Parkinsons OK but this is something else!!
