Hi, my father in law is in the early stages and is going through dizziness and foggyness in the mornings, sometimes losing his balance and generally feeling not upto much. This seems to fade after a few hours and he is ok. It does not happen every day either, some days he is just a little slow. Is this usual with Alzheimers or is this something else. The doctor came out to see him last week after a bad turn and checked him over saying very little and leaving us in the dark about why he is like this. Any ideas? Thanks
