Hi. My 72 year old Husband was diagnosed 5 years ago, also has other symptoms form Heart and diabetic conditions. Generally PD is not over severe, he is just really slow, bad and tremor and a little forgetful at times though PD progression has been slow. Some could be age related anyway. One weird thing is his facial expression. I have heard of a ‘mask’ which I can see at times in his general expression but he does really strange things with his mouth. (Sounds odd to describe really). Even in conversations he has his mouth wide open a lot and keeps putting his tongue out. Its almost like a grimace when people are doing something executive like lifting heavy objects etc. But he does this all the time. It almost looks scary and he doesn’t realise he is doing it. Could this be related to his PD?
