Each of one hundred and twenty-six patients who received insulin coma therapy and seventy-four patients who received electronarcosis were evaluated two weeks after the completion of therapy. The method of evaluation is outlined and tables of the results are supplied. The highest percentage of satisfactory results was correlated with the administration of ten or more treatments and with a duration of illness not exceeding twelve months. The patients who received insulin coma therapy did better than those who had electronarcosis. The EEG changes were severe in both the improved and unimproved patients who had undergone electronarcosis, while the patients who had insulin showed severe changes in the EEG only when improvement was noted and little change where there was no improvement. In nine mental functions (estimated by a battery of psychological tests) the insulin coma group showed either a greater gain or a smaller loss than the group which received electronarcosis. The findings suggest that it is of doubtful value to prolong electronarcosis beyond thirty treatments. This is not true of insulin coma.
