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

Infection
Parkinson's disease
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
Withdrawal from benzodiazepines
Stress
Alcohol withdrawal
Grief (yes, sadly)
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Mental disorder
Pharmaceutical drug (abuse or side effects)
Seizures
