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

Bipolar disorder

Head injury

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:

Migraines

Infection

Narcolepsy

Delirium tremens

Withdrawal from benzodiazepines

Alcohol

Stress

Seizures

Sleep disorders

Charles Bonnet syndrome

Affective disorders

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

Brain Tumors

Mental disorder

Grief (yes, sadly)

Pharmaceutical drug (abuse or side effects)

PTSD

Alzheimer's disease,

Parkinson's disease

Dementia with Lewy bodies
