hi people,i have noticed I have a new problem and I don't know if its common in vascular dementia. recently when I am reading anything I keep seeing the wrong words and misunderstanding the article.its very strange because I re read what I have read and I still cant make sense of it,but if I look later the right word is there and its making sense again.its very random when this happens.also I am not sleeping at night but I don't feel tired I can go on 3 or 4 hours sleep.the odd thing is my usual bedtime was between 10.30 to 11.30.but the nearer bedtime comes im less tired and a bit fidgety .I have tried going to bed but cant settle so up again after half hour.is this normal.
