Can certain diseases cause paranoia similar to that seen in...

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

Dementia with Lewy bodies

Parkinson's disease

Alcohol withdrawal

Narcolepsy

Bipolar disorder

Infection

Charles Bonnet syndrome

Seizures

Withdrawal from benzodiazepines

Stress

Head injury

Hallucinogen use

Sleep disorders

Fever

Mental disorder

Brain Tumors

Grief (yes, sadly)

Alcohol

Migraines

Delirium tremens

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

Affective disorders

Alzheimer's disease,

PTSD

Pharmaceutical drug (abuse or side effects)

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