⁉️sources from my experiences and internet research ⁉️

Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:

Brain Tumors

Pharmaceutical drug (abuse or side effects)

Head injury

Delirium tremens

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

Narcolepsy

Dementia with Lewy bodies

Alcohol withdrawal

Sleep disorders

Affective disorders

Alcohol

Alzheimer's disease,

Withdrawal from benzodiazepines

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