<bot>: Hi, Thank you for posting your query. I have noted your husbands' diagnosis of Parkinson's disease (PD) and his current symptoms of hallucinations and agitation. There are two main possibilities in this case:The most common cause for his hallucinations are medication-related. Levodopa is known to produce side effects of hallucinations, bad Chat Doctor.  To relieve this side effect, the dose of levodopa may be reduced, and the last dose should be completed before 7 pm. The other possibility could be an alternate diagnosis of DLBD (diffuse Lewy Body disease), which has clinical features similar to PD, but also has prominent hallucinations. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health,
