lewy body dementia
"My husband was recently diagnosed with Lewy Body Dementia, and the worst part was the hallucinations he was having of people coming in the house, threatening him, stealing things, hiding things and pretending to be me or one of his daughters.  There was no dealing with these imaginary people.  Our Neurologist suggested trying Donepezil (Aricept) and we started with 5 mg. and moved to 10 mgs since he had no side affects.  It was amazing: his hallucinations stopped completely by the third day!  They have never come back."
