ABSTRACT
There are two methods by which the subject of childhood psychosis can be attacked. By one method mental disease organizations that are well known in adult psychiatry can be described as occurring before puberty and in the years of early childhood. Creak (1952) takes one type of psychosis in which there is an organized introversion, with consequent bizarre behaviour pat terns and secondary disturbances of physical functioning, and she clearly describes a type of child that must be well-known to all child psychiatrists and to paediatricians. In the same way it would be possible to take melancholic states, manic-depressive mood swings, hypomanic restlessness, various kinds of confusional states, and to trace their common occurrence in childhood; the material for such a study is abundant.
