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

Alzheimer's disease,

Migraines

Hallucinogen use

Why do I sweat so much? I’m 17 but I feel like I always need to re-apply deodorant and I am always self-conscious that I smell because I feel sweat under my arms.

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

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:
