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

Narcolepsy

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

Dementia with Lewy bodies

Grief (yes, sadly)

Fever

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

Stress

Migraines

Alcohol

Infection

Affective disorders

PTSD

Charles Bonnet syndrome

Delirium tremens

Parkinson's disease

Bipolar disorder

Pharmaceutical drug (abuse or side effects)

Brain Tumors

Head injury

Seizures

Hallucinogen use

Alzheimer's disease,

Withdrawal from benzodiazepines

Mental disorder

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