F20-F29: Schizophrenia, schizotypal and delusional disorders

F24: Induced delusional disorder

Someone close to you has delusions. Delusions can be caused by mental illnesses. With hallucinations, your assessment of reality is wrong. You are then firmly convinced of something that does not correspond with the reality.

If you are very close to someone who has delusions, these convictions can be passed on. This is how your delusions were triggered.
