[|Human|] Hi, I have a 75 year old father-n-law who is experiencing seeing people in his house that is not there.  This morning he said that my mother-n-laws Indian statue collection was looking at him and laughing at him and he saw a rabbit or squirrel under a shirt on a foot stool.  His only medication he takes is aricept and has been on this for year or so.  Is this part of dementia?
[|AI|]  Hi, Thanks for using Chat Doctor. I have gone through your available history. Visual hallucination and delusions are part of psychotic symptoms associated with dementia. You should consult psychiatrist for detailed evaluation and management. After confirming diagnosis and ruling out other causes, doctor may advise him to take risperidone or aripiprazole like anti-psychotic agents in addition to cognitive enhancers. Doctor may advise Vitamin B12 blood test to rule out its deficiency as a cause. I hope It may help. Thanks.
