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

Narcolepsy

Alcohol

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

Seizures

Grief (yes, sadly)

Bipolar disorder

Head injury

Sleep disorders

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

Migraines

Parkinson's disease

Alcohol withdrawal

Withdrawal from benzodiazepines

Stress

Hallucinogen use

Infection

Pharmaceutical drug (abuse or side effects)

Alzheimer's disease,

Dementia with Lewy bodies
