Speaking of dementia in general, what are its symptoms?
Dementia symptoms are varied and depend to a great extent on the underlying disease or disorder causing them. Not all people with Alzheimer’s disease experience hallucinations (sensual perceptions of things that don’t exist), for example, while most people with Lewy body dementia, an illness that resembles Alzheimer’s, do hallucinate. In fact, symptoms may differ somewhat even among people with the same underlying disease or disorder. The symptoms a person develops depend in part on her underlying illness, in part on the severity and location of brain damage and in part on the person herself.
