ECT has high response rates for aggression and agitation in dementia

The researchers said that it may be particularly beneficial to try ECT in patients who showed an insufficient response to three or more antipsychotics or those treated with clozapine prior to admission, as these patients showed markedly superior outcomes when given ECT versus non-ECT. However, further studies of the effects of ECT on rates of relapse, readmission, or suicide in schizophrenia are needed.
