I'm worried about my father and thought I'd see if anyone could help. He's in his 60s and his personality seems to have changed. He used to be very get up and go but now he is quite spaced out and it seems like he is not quite with it. His driving has become erratic and he also sleeps a lot more than before, he used to get up quite early but this has been replaced by lie-ins. He's been to hospital for checks but we have to wait a while for any results. I'm always cautious about diagnosing online but I've got an issue at home at the moment too so want some information or hunches really. Any help appreciated x
