Alcohol withdrawal
Brain Tumors

Affective disorders
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:

Head injury
Mental disorder
Alcohol
Grief (yes, sadly)
Stress

Parkinson's disease
Seizures

Pharmaceutical drug (abuse or side effects)
