Psychological Test Performance in Patients Over Sixty. II. Paraphrenia, Arteriosclerotic Psychosis and Acute Confusion

The previous paper of this series (Roth and Hopkins, 1953) described test performance in senile and affective psychosis. The same tests have been administered to patients in three other diagnostic groups: paraphrenia, arteriosclerotic psychosis, and acute confusional states. These five clinical categories account for the majority of mental hospital admissions in patients over the age of 60.
