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

Head injury
Delirium tremens
Alcohol withdrawal
I just cannot wake up early, even if I sleep on time. What should I do?
Stress
Grief (yes, sadly)
Withdrawal from benzodiazepines
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Parkinson's disease

Charles Bonnet syndrome
Mental disorder
