Pharmaceutical drug (abuse or side effects)

Stress

Alzheimer's disease,

Mental disorder

Hallucinogen use

Affective disorders

Infection

Grief (yes, sadly)

Parkinson's disease

Charles Bonnet syndrome

Migraines

Brain Tumors

Narcolepsy

Dementia with Lewy bodies

Sleep disorders

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

Alcohol

Alcohol withdrawal

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

Head injury

Delirium tremens

Withdrawal from benzodiazepines

Bipolar disorder

Fever

PTSD

Seizures

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