The recent Nigerian study that found no difference at the end of treatment also failed to find any significant differences 20 weeks later (Ukpong et al., 2002). Thus of eight follow-up studies (four on depression, four on ‘schizophrenia’) seven found no difference at the first follow-up and one, a ‘schizophrenia’ study (comparing ten ECT patients with ten SECT) found a significant difference at two weeks, but not four.
