Patients treated with electroconvulsive therapy (ECT) were divided into those with less severe depression and those with more severe depression. In the less severely depressed group, high somatic anxiety and hypochondriasis predicted a low likelihood of sustained remission with ECT. In the more severely depressed group, these traits were not predictive of ECT outcome.
Continuation and maintenance electroconvulsive therapy (ECT) are used to prevent relapse of depression after a successful course of index ECT. Such a course of treatment is typically extended for as long as a year. However, some patients seem to require longer courses of maintenance ECT. Little is known about the outcomes of long-term use (> 1 year) of maintenance ECT. We reviewed our maintenance ECT practice for the year 2000 and found that 43 patients had been receiving maintenance ECT for more than a year. This retrospective study reviews the outcomes of these patients. All patients had depression associated with either unipolar or bipolar disorder or schizoaffective disorder. These patients had multiple medication or psychotherapy trials or both and multiple hospitalizations before receiving maintenance ECT. Effects on depressive symptoms, level of functioning, health care use, frequency of hospitalizations, and cognition are discussed. We conclude that extended maintenance ECT is efficacious and well tolerated and reduces hospital use for a population of chronically depressed patients refractory to medication.
Patients with dementia and depression are commonly encountered in ECT practice. A large body of case reports and case series in demented patients attests to the utility of ECT in treating concomitant depression in this population. However, there are no reported cases of patients with suspected Lewy Body dementia and depression treated with ECT. We describe our experience in treating seven such patients. All of them enjoyed substantial relief from depression with ECT, which they tolerated well. It is concluded that ECT can be effective in treating depression associated with probable Lewy Body dementia.
OBJECTIVE: Factitious disorder with physical symptoms characterizes patients who strive to appear medically ill and assume the sick role. Clinical suspicion is highest for female health care workers in the fourth decade of life. This study was designed to analyze the diagnosis of factitious disorder, the demographics of affected patients, and intervention and treatment. METHOD: Retrospective examination was of 93 patients diagnosed during 21 years. Two raters agreed on subject eligibility on the basis of DSM-IV criteria and absence of a somatoform disorder and a plausible medical explanation. RESULTS: The group included 67 women (72.0%); mean age was 30.7 years (SD=8.0) for women and 40.0 years (SD=13.3) for men. Mean age at onset was 25.0 years (SD=7.4). Health care training or jobs were more common for women (65.7%) than men (11.5%). Most often, inexplicable laboratory results established the diagnosis. Eighty had psychiatric consultations; 71 were confronted about their role in the illness. Only 16 acknowledged factitious behavior. Follow-up data were available for only 28 patients (30.1%); maximum duration of follow-up was 156 months. Two patients were known to have died. Few patients pursued psychiatric treatment. Eighteen left the hospital against medical advice. CONCLUSIONS: Factitious disorder affects men and women with different demographic profiles. Diagnosis must be based on careful examination of behavior, motivation, and medical history and not on a stereotype. Laboratory data and outside medical records help identify suspicious circumstances and inconsistencies. Confrontation does not appear to lead to patient acknowledgment and should not be considered necessary for management.
