Delusions - false beliefs which persist in spite of incontrovertible evidence to the contrary and which are out of harmony with the individual's cultural and religious background. Primary delusions arise 'out of the blue' (e.g. sudden delusional ideas, delusional perception, delusional mood). Secondary delusions arise from a 'morbid' experience such as an hallucination.
