CLASSIFICATION of DELUSIONS:
Delusions can be classified as:
a) Primary delusions, also known as apophanous delusions, delusions proper or true
delusions. They are the result of a primary delusional experience which cannot be
deduced from any other morbid phenomenon. The essence of primary delusional
experience is that a new meaning arises in connection with some other psychological
event.(1)
Fish (1967b) has linked them to the " brain wave " of normal individual where an idea
presents itself suddenly in consciously, but primary delusion has the characteristics(1).
Schneider has suggested that experiences can be reduced to three; viz delusional mood,
delusional perception (apophanous) and sudden delusional ideas (autochthonous
delusion).
