Stroke with abnormal side effects

My uncle just suffered a stroke the day after his son's wedding (stroke occurred yesterday.) He is able to walk around, go to the bathroom without help, etc but he is completely incoherent in regards to who is around him and his speech is awkward. He's speaking with proper grammar and so forth, but his sentences just break off. He kept repeating things like "I was driving and then (total change of tone to high pitch) I saw the cutest little fishing lure!" He seems to think it's 1979 and many of his random sentences involve fishing (major hobby of his), girls from 1979 and his car from back then. The car could actually be either or, but the sentences seem pretty 1979 themed except the fishing stuff. He has no noticeable drooping, paralysis, etc. He just keeps crumbling up into a fetal position, talking randomly, etc. He went to the bathroom on his own and he keeps talking about how he has to get out of there (being the hospital.) He was unconscious in his car in a parking lot.

I would agree that the doctors have been unhelpful. However, there care so far has seemed pretty standard and up-to-date. Where they are clearly failing, though, is communicating with you and informing you as to what may or may not be happening.

Strokes are caused by a lack of blood flow to part of the brain--this in turn can have many causes, including (but not limited to) head trauma, seizures, clots, brain tumors, brain infections and so on. The MRI is not just to confirm he had a stroke, but to perhaps determine the cause of the stroke. In addition, it will tell you how large the stroke is, and this, in turn, can tell you what to expect in terms of recovery.
