question: My husband had a stroke when he was six years of age.  He now is 39 we have started to notice signs of memory loss, increased anger and irritablilty.  Our primary doctor said it should not get any worse however our nerologist said it looks like the first stages of dementia.  I am confused if it is vascular dementia why would our primary Doctor tell us it should not get any worse.  He is showing signs of disoringtation etc..  Please help my utter confusing and should i be worried something could happen to him in the next few years?
