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

Charles Bonnet syndrome

Affective disorders

Seizures

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

Migraines

Narcolepsy

Pharmaceutical drug (abuse or side effects)

Stress

Withdrawal from benzodiazepines

⁉️sources from my experiences and internet research ⁉️

Bipolar disorder

Infection

Delirium tremens

Grief (yes, sadly)

Dementia with Lewy bodies

Brain Tumors

Head injury

Alcohol

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

Parkinson's disease

PTSD

Hallucinogen use

Sleep disorders

Mental disorder

Alzheimer's disease,

Alcohol withdrawal

Fever

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