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:

Withdrawal from benzodiazepines

Bipolar disorder

Alcohol

Pharmaceutical drug (abuse or side effects)

Fever

Alcohol withdrawal

Narcolepsy

Sleep disorders

Delirium tremens

Mental disorder

Stress

Grief (yes, sadly)

Migraines

Brain Tumors

Affective disorders

Alzheimer's disease,

Dementia with Lewy bodies

Parkinson's disease

Seizures

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

Hallucinogen use

Head injury

PTSD

Infection

Charles Bonnet syndrome

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