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

Withdrawal from benzodiazepines
Sleep disorders
Alcohol withdrawal
Delirium tremens
Migraines
Narcolepsy
Affective disorders
Hallucinogen use
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:

Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
