Combined electroconvulsive therapy and clozapine in treatment-resistant schizophrenia.

1. To assess the efficacy and safety of combining electroconvulsive therapy (ECT) and clozapine in patients with treatment-resistant schizophrenia, the authors reviewed use of this combination in four treatment-resistant schizophrenic inpatients and one inpatient with schizophrenia who was intolerant of clozapine doses needed to control her psychosis. 2. The combination of clozapine and bilateral ECT was modestly effective in two treatment-resistant patients and markedly effective in three patients. There was significant overall improvement in patients' Clinical Global Impression (CGI) and Global Assessment of Functioning (GAF) scores (p < 0.005 and p < 0.0004, respectively), however in patients where marked symptomatic improvement was noted, effects were not sustained. 3. One of the patients that showed dramatic yet transient improvement followed by relapses received maintenance ECT but relapsed despite this. 4. The authors saw no adverse effects in connection with the combination of ECT and clozapine. 5. Supplementing clozapine with a course of bilateral ECT appears to be safe and is effective in some patients with refractory schizophrenia, however its beneficial effects may be short-lived. The long-term impact of ECT on the course of schizophrenia in patients incompletely responsive to clozapine is not fully elucidated.

Does neuroanatomy predict ECT response?

1. Structural neuropathologic abnormalities have been associated with severe psychiatric illnesses, including bipolar disorder, major depressive disorder, and schizophrenia. In the latter, ventricular enlargement has been variably associated with symptom severity and poor treatment response. In patients with severe depressive disorders, the relationship between cortical and subcortical pathology and ventricle enlargement, symptom severity, and response to treatment is far from clear. 2. The present study investigated the relationship between structural CNS pathology, symptom severity and treatment response in patients undergoing ECT. It was hypothesized that patients with greater neuroanatomic abnormalities would demonstrate greater initial symptom severity and poorer response to ECT. 3. The subjects were 57 patients with unipolar or bipolar depression admitted for ECT treatment. Symptom severity was quantified using the Hamilton Depression Rating Scale (HRSD) at baseline and post-ECT. 4. Lateral and third ventricle-brain ratio (LVBR, 3VBR) were determined from CT scans and cortical atrophy was rated by a faculty neuroradiologist. 5. Contrary to our first hypothesis, structural pathology was not associated with baseline symptom severity. In terms of treatment response, the number of treatments required to achieve benefit was correlated with larger 3VBR; CT variables were not related to total post-treatment or change in HRSD score. Third ventricle enlargement may be an index of generalized pathology or regional brainstem abnormalities that influence ECT response rate by limiting individual seizure efficacy or neurochemical responsiveness, thereby necessitating a greater number of ECT treatments, without significant impact on overall response.

Electroconvulsive treatment in adolescents with pharmacotherapy-refractory depression.

The effectiveness and safety of ECT in pharmacotherapy-refractory depression was examined in 11 hospitalized adolescents (ages 16.3 +/- 1.7 years, 10 females) with a primary DSM-III-R diagnosis of mood disorder, which had failed to respond to three or more adequate trials of antidepressant pharmacotherapy. After a thorough diagnostic evaluation, patients received a course of ECT involving 11.2 +/- 2.0 (range 8-15) administrations. ECT was commenced with bilateral treatment in 2 adolescents and nondominant right electrode placement in 9 patients; 5 of the 9 patients were subsequently changed to bilateral treatment. All 11 patients improved to a clinically significant degree. Significant improvements were noted in scores on the Children Depression Rating Scale-Revised (CDSR-R) and the Global Assessment of Functioning Scale (GAF) (p < 0.05). Euthymia, defined as CDRS-R score < or = 40, was achieved by 64% (7/11) of patients. The Mini-Mental State Examination showed no significant decline in cognitive functioning. Neuropsychological testing completed in 5 subjects both before ECT and 1-5 days after the last treatment, indicated a significant decline in attention, concentration, and long-term memory search. Minor side effects, experienced within the first 12 hours of treatment, were headache (80% of patients) and nausea/vomiting (64%). The potentially serious complication of tardive seizure (after full recovery of consciousness) occurred in 1 adolescent. Prolonged seizures (> 2.5 minutes) were noted in 7 of the 11 patients (9.6% of the 135 ECT administrations). Pending further research on ECT in youth, it is recommended that ECT should only be administered to youth in hospital settings, that all regularly administered psychotropic medications (including antidepressants) be discontinued before ECT and restarted after the final administration of ECT, and that physicians be aware that 12 treatments are usually sufficient, but that 15 treatments may occasionally be necessary for treating depressed adolescents. With the understanding that scientific evaluation of ECT in youth is lacking, it appears that ECT can be an effective and relatively safe treatment for depressed adolescents who have failed to respond to antidepressant pharmacotherapy.

Electroconvulsive therapy and intracranial aneurysm.

Little has been written regarding the safety of electroconvulsive therapy (ECT) administered to patients with intracranial aneurysms. The literature is reviewed and we report two additional cases of ECT safely and effectively employed to treat depressed patients with intracranial aneurysms. We found no reported cases of aneurysm rupture associated with ECT. We do not feel the presence of intracranial aneurysm is a contraindication to ECT, in most patients, with appropriate monitoring and control of arterial blood pressure.
