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

Mental disorder
Fever
Pharmaceutical drug (abuse or side effects)
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
Charles Bonnet syndrome
Dementia with Lewy bodies

Grief (yes, sadly)
Infection
Alcohol

Parkinson's disease

Narcolepsy

Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Alzheimer's disease,
Bipolar disorder
Brain Tumors
Head injury
Affective disorders
Hallucinogen use
Delirium tremens
