Delusions: Symptoms & Signs

A delusion is a false personal belief that is not subject to reason or contradictory evidence and is not explained by a person's usual cultural and religious concepts (so that, for example, it is not an article of faith). A delusion may be firmly maintained in the face of incontrovertible evidence that it is false. Delusions are common in psychotic disorders such as schizophrenia. Delusions can also be a feature of brain damage or disorders. Delusions can be accompanied by other psychiatric symptoms or by physical symptoms when these occur related to a medical condition. Delusional disorder is a specific psychiatric condition that was formerly known as paranoid disorder. Examples of delusions include the sufferer believing that one has an unusual power or talent, believing that someone else (possibly a prominent figure or famous person) is in love with them, believing that one is being persecuted, or believing that one has a nonexistent medical problem.
