To facilitate the systematic description of catatonic signs, we developed a catatonia rating examination, rating scale and screening instrument. We constructed a 23-item rating scale and a truncated 14-item screening instrument using operationalized definitions of signs ascribed to catatonia in published sources. Inter-rater reliability was tested in 44 simultaneous ratings of 28 cases defined by the presence of > or = 2 signs on the 14-item screen. Inter-rater reliability for total score on the rating scale was 0.93, and mean agreement of items was 88.2% (SD 9.9). Inter-rater reliability for total score on the screening instrument was 0.95, and mean agreement of items was 92.7% (SD 4.9). Diagnostic agreement was high based on criteria for catatonia put forth by other authors. Seven per cent (15/215) of consecutively admitted patients to an academic psychiatric in-patient facility met criteria for catatonia. It is concluded that catatonia is a distinct, moderately prevalent neuropsychiatric syndrome. The rating scale and screening instrument are reliable and valid. Their use facilitates diagnosis, treatment protocols, and cross-study comparisons.
Background: Deep brain stimulation (DBS) of the subcallosal cingulate white matter (SCC) has shown promise as an intervention for patients with chronic, unremitting depression (TRD). To test the safety and efficacy of DBS for TRD, a prospective, randomized, sham-controlled trial was conducted. Methods: Participants with TRD were implanted with a DBS system targeting bilateral SCC white matter and randomized to six months of active versus sham DBS followed by six months open-label SCC DBS. The primary outcome was response rate at the end of the six-month double-blind phase. Response was defined as a 40% or greater reduction in depression severity from baseline. A futility analysis was performed when approximately half of the proposed sample received DBS implantation and completed the double-blind phase. At the conclusion of the 12-month study, a subset of patients continued to be followed for up to 24 months. Findings: Prior to the futility analysis, 90 participants were randomized to active (N=60) versus sham (N=30) stimulation. Both groups showed improvement, but there was no statistically significant difference in response rate during the double-blind, sham-controlled phase. Participants continued to improve during the six months open-label phase. Long-term response and remission rates for all participants receiving active DBS open-label were, respectively, 40% and 19% at 12 months, 51%
Each electrode placement is a very effective antidepressant treatment when given with appropriate electrical dosing. Bitemporal leads to more rapid symptom reduction and should be considered the preferred placement for urgent clinical situations. The cognitive profile of bifrontal is not substantially different from that of bitemporal.
Case material and retrospective studies support the use of both lorazepam and ECT in treating catatonia, but few prospective investigations exist and none employ quantitative monitoring of response. In this study we test their efficacy in an open, prospective protocol, and define a "lorazepam test' with predictive value for treatment. Twenty-eight patients with catatonia were treated systematically with parenteral and/or oral lorazepam for up to 5 days, and with ECT if lorazepam failed. Outcome was monitored quantitatively during the treatment phase with the Bush-Francis Catatonia Rating Scale (BFCRS). In 16 of 21 patients (76%) who received a complete trial of lorazepam (11 with initial intravenous challenge), catatonic signs resolved. A positive response to an initial parenteral challenge predicted final lorazepam response, as did length of catatonic symptoms prior to treatment. Neither demographic variables nor severity of catatonia predicted response to lorazepam. Four patients failing lorazepam responded promptly to ECT. It is concluded that lorazepam and ECT are effective treatments for catatonia. The rating scale has predictive value and displays sensitivity to change in clinical status.
Bilateral ECT is effective in relieving severe major depression. Remission rates are higher and occur earlier in psychotic depressed patients than in nonpsychotic depressed patients. These data support the argument that psychotic depression is a distinguishable nosological entity that warrants separate treatment algorithms.
Objective-This study assessed the incidence, severity, and course of expressed suicidal intent in depressed patients who were treated with ECT. The data are from the first phase of an ongoing, collaborative multicenter study, the overall aim of which was to compare continuation ECT with pharmacotherapy in the prevention of relapse after a successful course of ECT.Method-Suicidal intent, as expressed by patients during an interview, was scored at baseline and before each ECT session with item 3 on the 24-item Hamilton Depression Rating Scale in 444 patients with unipolar depression.Results-One hundred thirty-one patients (29.5%) reported suicidal thoughts and acts (score of 3 or 4) at baseline. Scores decreased to 0 after 1 week (three ECT sessions) in 38.2% of the patients, after 2 weeks (six ECT sessions) in 61.1%, and in 80.9% at the end of the course of treatment.Conclusions-Expressed suicidal intent in depressed patients was rapidly relieved with ECT. Evidence-based treatment algorithms for major depressive mood disorders should include dichotomization according to suicide risk, as assessed by interview. For patients at risk, ECT should be considered earlier than at its conventional "last resort" position.Suicide and suicide attempts are risks of the major psychiatric illnesses, with mortality rates markedly higher than for the general population (1). A lifetime risk of 15% for suicide was the conclusion of a meta-analysis of hospitalized patients by Guze and Robins (2). A reanalysis of studies of suicide in affective illness in three groups of patients-outpatients, inpatients, and suicidal patients-found a risk of those ever hospitalized of 8.6% (3). Other studies confirmed the risk of suicide to be particularly high in hospitalized depressed patients (4-6). Profound hopelessness, hypochondriacal ruminations or delusions, and thoughts of suicide or self-harm during depression predict future suicide (7).Antidepressant medications are the principal agents used to treat affective disorders today. Their impact on suicide risk is not well defined, however, and they are generally viewed as less effective than ECT in relieving depression and suicidal thoughts. Hordern et al. (8) reported no suicides at the 6-month follow-up in 34 women treated with ECT but found two in the 84 patients treated with antidepressants (2.4%). Avery and Winokur (9) suicidal behavior in the 6 months following the treatment of depression in 519 patients. Suicide attempts were recorded in 0.8% of the ECT patients compared to 4.2% of those who had received "adequate" and 7% "inadequate" antidepressant medication treatment. Khan et al. (10) found antidepressant drugs to be no more effective than placebo in reducing suicide rates in seriously ill depressed patients.The experience with ECT is also unclear. A comparison of the frequency of suicides in different decades found decreased rates when ECT was the dominant treatment for mental illness (11). An examination of the records of 1,397 completed suicides in Finland within a 12-m...
The augmentation of clozapine with ECT is a safe and effective treatment option. Further research is required to determine the persistence of the improvement and the potential need for maintenance treatments.
