Thank you. No he doesn't have a uti. Was recently checked. Neither does he have anaemia. Forgot to mention that he has parkinsons due to TIA's. Also has han a stroke one year ago.i would contact the doctor just in case of a uti, any other conditions anaemia, just to rule out things. how long has he had it? my husband has had vascular dementia for 4 years, diagnosed 3 years and he can sleep for england. all night but some of the day too.
