This is a study of fourteen patients originally suffering from obsessive-compulsive symptoms, seven of whom developed depressive states and seven schizophrenic (including paranoid) states.

Depressive conditions accompanied by obsessive-compulsive symptoms tend to display aggressive, destructive, obsessional ideas and compulsions along with suicidal impulses. The obsessive-compulsive symptoms often overshadow the depressive state which is easily missed.

In the schizophrenic group primitive impulses are often released which were previously kept under control with the aid of the obsessional and compulsive
