Delusional disorder is a mental health condition characterized by the presence of delusions —fixed false beliefs held with absolute certainty, despite strong evidence to the contrary. These delusions are usually inconsistent with a person’s cultural rules.
Delusional disorder tends to develop in mid to later life and is more common in women than it is in men.
Schizophrenia vs Delusional Disorder
Unlike schizophrenia, mood symptoms in delusional disorder tend to be brief or absent, and hallucinations are not usually present. If they are, they are often minimal.
