has anyone noticed if there are any signs of T.I.As in vascular dementia. my husband has A & Vascular but i have noticed he gets very aggressive not violent but very threatening (which would upset him if he could remember) this carries on for a few days and then he will sleep forall night (lovely) and all day if left afterwards he has lost more memory. I just wondered if any on else had noticed this or is it a symptom alspo he cannot remeber anyu thing about the last two weeks that's fairly normal for him
