Delusional disorder is a mental illness that causes a person to have delusional thoughts for a prolonged period.
A person with delusional disorder will have delusional thoughts that are not entirely bizarre or unrealistic. They are usually based on something that could possibly happen to the person in real life, such as someone following or deceiving them.

Delusional disorder is a rare condition, with estimates suggesting that the probability of a person developing it during their lifetime is as low as 0.05–0.1%.

Some of the more common types of delusions are:
•Delusional jealousy: A person may incorrectly think that their partner is being unfaithful.
•Romantic: The individual may believe that another person is in love with them.
