This is the sixth and final paper of a series studying various symptomatic, physical and social aspects of a sample of 47 cases of infantile psychosis (I.P.) and 33 cases of late onset psychosis (L.O.P.). They were seen at the Park Hospital for Children, Oxford, and the Newcastle Child Psychiatry Unit.
