Is anyone else coping with this? My husband falls asleep as soon as he sits down and then when he wakes or I wake him, he can become very confused. Consultant trying to improve his nightime sleep with melatonine to prevent daytime sleepiness but not working. He was diagnosed 9 years ago and is taking Stalevo TDS. I am so worried that this may be the start of Parkinson's dementia. He is often uncommunicative, then at other times he seems quite alert again. Up and down seems to b a feature of this horrid condition.
