1. One hundred and two long-term schizophrenics were treated with ECT during a period of 15 months.2. Eight were released from the hospital; 8 are expected to be released; 35 showed marked improvement; 20 showed improvement in attitude and behavior; and 31 are considered unimproved.3. ECT is considered a useful method in long-term schizophrenics, provided it is given in sufficient amount for a long enough period of time. Although the percentage of those discharged from the hospital is small, a large percentage of these patients have become much better adjusted to hospital life. An important result is marked improvement in the morale of patients and personnel.4. Long duration of illness should not be a reason for denying ECT to schizophrenic patients, nor should the diagnostic subtype be considered a contraindication to treatment.5. The possible value of maintenance treatment is pointed out by the fact that 66 of the 102 patients are continuing on maintenance treatment successfully to date. Further investigation is necessary to come to a definite conclusion as to its value.
