Ever since I was diagnosed with PV 18 months ago I have had ever increasing memory problems. I won't talk to anyone on the phone because I can't find the words I am looking for and I have to ask my husband what I need to say. Also at times of added stress I always lose my train of thought and forget what I was talking about. As for names, forget it. If I see someone on TV I sit for hours wondering what their name is. I don't know if this confusion is part of PV, a side effect of taking the Hydroxy or, heaven forbid, the start of dementia. I wonder at times if I could have had a mild stroke? I cannot stand the not knowing how so I am going to ask my consultant when I see her next week. Just wanted to know if anybody else has these problems?
