Pollock[223] has made a most interesting study of 1,739 cases of alcoholic psychoses, the total number admitted to the New York state hospitals between October 1, 1909, and September 30, 1912. Seventy-six and five-tenths per cent of these were men, and 23.5 per cent, women. The different conditions represented were as follows: Pathological intoxication, .7 per cent; alcoholic deterioration, 7.7 per cent; delirium tremens, 4.7 per cent; Korsakow's psychosis, 18.8 per cent; acute hallucinosis, 36.7 per cent; chronic hallucinosis, 2.2 per cent; paranoid states, 13.7 per cent; and all other forms, 15.5 per cent. Among the males, acute hallucinosis predominated, while Korsakow's psychosis constituted the largest percentage in the female patients. Of the ascertained cases, .4 per cent showed a defective make-up, 10.3 per cent were inferior and 89.3 per cent were reported as normal. In seventy-four per cent of the cases there was no history of insane heredity. The father of the patient was insane in 3.7 per cent of the series and the mother in four per cent; 25.8 per cent in all had a history of insane heredity. Thirty and five-tenths per cent of the male and thirty-seven per cent of the female patients had alcoholic fathers and three per cent of the men and 8.8 per cent of the women had alcoholic mothers. Pollock found the percentage of intemperate fathers twice as high in the alcoholic psychoses as in the patients suffering from other conditions. In 94.1 per cent of the cases there was no family history of nervous diseases. Eighty-one and one-tenth per cent of the men and 93.4 per cent of the women came from cities. Of the male patients 26.8 per cent were unskilled laborers; 16.1 per cent of the women were seamstresses, and 11.7 per cent, the wives of laborers. The alcoholic cases constituted fifteen per cent of the male, five per cent of the female, and ten per cent of the total first rate admissions during the three years in question. The rate of alcoholic psychoses was over twice in as great in the foreign born population as in the native.
