Of 100 cases of hysteria observed in soldiers in the U. S. Army Hospital for War Neuroses at Plattsburg Barracks, N. Y., there was a neuropathic family history in 64, a negative family history as regards neuropathic conditions in 35, and data unascertained in the remaining case. In the same group of cases it was found that there was a history of social maladjustment in some form prior to enlistment in 51 cases, a negative history as regards social maladjustment in 47 cases, and history unascertained in 2 cases. As evidences of neuropathic heredity were counted cases in the family of epilepsy, fainting spells, sick headache, insanity, feeblemindedness, alcoholism, criminalism, eccentricities, temperamental anomalies, nervous breakdown, etc. As items of social maladjustment were counted the following data in the personal history: poor progress in school, poor showing in work, intemperance, criminalism, etc. In 77 out of the 100 cases there was either a neuropathic family history, or a history of social maladjustment in the individual, or both.
Thus, it would seem that hysterical phenomena arise on a basis of neuropathic constitution.1
