hi im hoping you can help me.
my dad is 57 years old and a hard worker,but today as he had no work he was at home,he looked very tired,but he was fighting it,he was walking around the house looking for his car keys,then started looking for the dog which was sat in front of him,he kept saying he was cold,then said oh its hot,it was like he was coming out in a cold sweat,but he kept asking for things that was near him,he was walking around the house looking confused.then he cuddled my mother and didnt want to let go.she tols him to go to bed but he wouldn't go so he has now fallen asleep on the sofa.
could you tell me if this is a sign of alzheimer's? if not what is wrong with my dad?
