Please can anyone tell me why Tegretol is being used in the elderly with vascular dementia. My aunt was taken into hospital from her care home 6 weeks ago and she has declined rapidly - we're not sure what is going on, they (the doctors) seem to be changing her medication on a whim. She is now on Tegretol and Lorazapam. My aunt hasn't had any seizures, although she has been very agitated and can be aggressive.
