My dad was diagnosed with PSP 3 years ago. He was reasonably well, but now seems to have suddenly detiorated in the last month. He is falling more, incredible tiredness & waking up at odd hours in the night, unable to sleep. He is finding it difficult to swallow.
What is now worrying me most is whether he is delusional after waking up? He packs bags, saying he has a flight to catch & will refuse to listen otherwise. He gets ready to go to work, call his previous colleagues to meet him at office. My mother had to physically stop him from leaving the house. He would search for my sister in the house saying she was there a while ago when she had not visited. He goes to take a shower very early in the morning. Mostly some of his odd behaviour stops because he is too tired & will try & lie down on his own. I would be grateful if somebody can clarify if there is a range of cognitive impairments for people with PSP?
