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

Sleep disorders

Fever

Alzheimer's disease,

Charles Bonnet syndrome

PTSD

Head injury

Alcohol

Pharmaceutical drug (abuse or side effects)

Parkinson's disease

Infection

Bipolar disorder

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

Alcohol withdrawal

Affective disorders

⁉️sources from my experiences and internet research ⁉️

Delirium tremens

Grief (yes, sadly)

Dementia with Lewy bodies

Mental disorder

Hallucinogen use

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

Brain Tumors

Seizures

Migraines

Withdrawal from benzodiazepines

Stress

Narcolepsy

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