The author compared 94 depressed patients with 94 nondepressed patients who had a personality disorder in a matched control study. A family history of depression, parental loss before 17 years, and unemployment were found to be risk factors associated with depression in the women. In the men, however, parental loss was the only factor associated with depression.
In a matched controlled study 37 chronic schizophrenics who had taken LSD preceding the onset of their illness were compared with schizophrenics who had not. There were no significant differences between the groups either on age at onset of symptoms or for age at first admission.

The computer-instigated development of graphic depictions showing rationales and decisions required in the care of patients has allowed clinicians to standardize science in the art of clinical medicine. Such condensation of medical judgment and information into algorithms is particularly important for emergency medicine. This paper describes the background and development of such algorithms in a research setting, and suggests modes for adaptation to clinical settings.
In a matched controlled study 102 patients with neurotic depression were compared with other neurotics. There was significantly more parental loss before 17 years of age in the depressive patients.
Among 231 cases of manic-depressive illness parental loss before 17 years was high but was not associated with earlier onset of illness.
Amongst 100 chronic paranoid schizophrenics depression occurred in 30 per cent over a mean 6 years and was significantly associated with parental loss before 17 years.
