I am trying to figure out what is going on with my 82 year old father. He was recently diagnosed with vascular dementia after getting two MRIs and a EEG (along with some other tests). But his symptoms are strange:
1. He has had these episodes where he collapses into semi-consciousness, then wakes up totally confused, to the point he can't remember his own name, the date, etc. He doesn't recognize family members and is "out of it". But he then recovers to some degree, and becomes more coherent and lucid. This has happened at least twice, and the last time it landed him in the hospital for 7 days. In addition to the problems above, he was combative and uncooperative.
2. Over the last couple of years, he has become much weaker, walks very slowly, and has very poor balance (has to grip onto things to keep from falling). He has some back and shoulder problems (arthritis), but the physical symptoms have gotten much worse in the last 6 months or so. He tends to drag his right foot a bit.
3. He has memory issues, but they aren't always obvious. he will say his grandson is 10 years old, when the actual age is 16. He forgets dates, and has trouble with his finances. He can't write a check, and has to have someone else do it for him.
4. After checking him into a rehab facility after the last major "episode", he was found wandering the halls naked in the middle of the night.
5. He is depressed, anxious, and his personality seems to have changed to some degree.
What confuses me are the "ups and downs" --sometimes he is obviously impaired, and at other times he is pretty lucid (although his eyes seem glazed, almost as if he is drunk --he is on a lot of meds).
Is this normal with vascular dementia? To have these periods of lucidity followed by major cognitive episodes?
