Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Pharmaceutical drug (abuse or side effects)
Head injury
Delirium tremens

Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
