Parkinson's disease
PTSD
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:

Withdrawal from benzodiazepines
Alzheimer's disease,
Delirium tremens
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
