Sleep disorders

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

Dementia with Lewy bodies

Mental disorder

Migraines

Alzheimer's disease,

Pharmaceutical drug (abuse or side effects)

Charles Bonnet syndrome

Alcohol withdrawal

Affective disorders

Can certain diseases cause paranoia similar to that seen in individuals with paranoid schizophrenia, even if they do not have the disorder?
