<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been having trouble sleeping lately and sometimes I feel weak in one side of my body. I have also been seeing and hearing things that arent really there.  <response>: Based on the symptoms you described, it sounds like you may be experiencing a type of dementia. Depressive and psychotic symptoms, insomnia, focal weakness, and delusions or hallucinations are common in people with dementia. I recommend further evaluation and testing to confirm a diagnosis and discuss treatment options.
