Parkinson's disease

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

Sleep disorders

Infection

Mental disorder

Pharmaceutical drug (abuse or side effects)

Alcohol

Migraines

Affective disorders

Bipolar disorder

Alzheimer's disease,

Head injury

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)

Withdrawal from benzodiazepines

Charles Bonnet syndrome

Hallucinogen use

Dementia with Lewy bodies

PTSD

Alcohol withdrawal

Seizures

Fever

Brain Tumors

Delirium tremens

Stress

Narcolepsy

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