Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Migraines
Dementia with Lewy bodies
Grief (yes, sadly)
Sleep disorders
Affective disorders
Parkinson's disease
Alcohol
Fever
Brain Tumors
Infection
Alcohol withdrawal
Eos iste et tenetur sunt rerum eligendi.
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
