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

Bipolar disorder
Hallucinogen use
Stress
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Alcohol withdrawal
Seizures
Brain Tumors
Withdrawal from benzodiazepines
PTSD

Pharmaceutical drug (abuse or side effects)
Grief (yes, sadly)
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
