Acute embolic stroke in a patient with atrial fibrillation after electroconvulsive therapy.

Although patients with atrial fibrillation (AF) have an increased risk of embolic stroke, some clinicians hesitate to provide anticoagulation therapy for these patients during electroconvulsive therapy (ECT), which is widely applied for the treatment of intractable depression, bipolar disorder, and catatonic schizophrenia, because of potential intracerebral hemorrhage. We report on a 77-year-old female depressive patient with AF treated with aspirin but not on anticoagulation therapy because of poor compliance who developed embolic stroke 1 day after the last ECT. The CHADS2 score of this patient was 2 and included the age and hypertension. The present case suggests that anticoagulation therapy should be considered for patients with obvious risks of embolic stroke when they are subjected to ECT.

Repeated electroconvulsive therapy courses improved chronic regional pain with depression caused by failed back syndrome.

BACKGROUND: Electroconvulsive therapy (ECT) is reported to be effective for intractable chronic pain with depression. However, not much has been done to clarify the ECT target in patients, whether the pain or the depression. We report a case of intractable chronic regional pain syndrome (CRPS) with secondary depression in which the depression was treated successfully with an initial acute ECT course, and the pain finally improved with two additional ECT courses. CASE REPORTS: The patient was a 48-year-old woman with CRPS and depression caused by failed back syndrome. The CRPS with depression did not respond to standard treatments. A course of bilateral acute ECT (12 sessions) improved the depressive symptoms but not the pain. The depression relapsed 1 month after the response to ECT. A second course of acute ECT (20 sessions) followed by continuation ECT (11 sessions) improved the depression but not the pain. The depression recurred 1 year after the response to acute ECT. A third course of acute ECT (12 sessions) finally improved the pain and resolved the depression. CONCLUSIONS: Our experience in thin case suggests that the therapeutic target in patients with chronic organic pain and secondary depression should be the pain; repeated ECT courses are likely to be effective for the pain, although the depression may resolve first.

A case of catatonia resembling frontotemporal dementia and resolved with electroconvulsive therapy.

We describe a case of catatonia in a 51-year-old man in whom the catatonic symptoms could not be distinguished from symptoms of frontotemporal dementia (FTD) until they were resolved with electroconvulsive therapy (ECT). When it is difficult to distinguish between catatonia and FTD in patients with frontal dysfunction associated with frontal lobe atrophy, we believe that sequential administration of benzodiazepines and ECT is important for therapeutic diagnosis because the risk of missing a diagnosis of catatonia outweighs the risks associated with administration of benzodiazepines and/or ECT.

Safety of electroconvulsive therapy in psychiatric patients shortly after the occurrence of pulmonary embolism.

We encountered 2 patients with a psychiatric disorder (depression in one and catatonia in one) accompanied by motor inhibition that was complicated by pulmonary embolism (PE). In both cases, the psychiatric disorder was safely resolved with electroconvulsive therapy (ECT) during anticoagulant therapy. The 2 cases direct our attention to at least 3 important points regarding safe administration of ECT shortly after the occurrence of PE, that is, careful evaluation of cardiac function and residual deep vein thrombosis before the start of an ECT course, adjustment of anticoagulants, and prevention of recurrent deep vein thrombosis and PE by methods in addition to anticoagulant therapy (fluid infusion, use of support hose, and timely ECT).

Catatonia complicated by pneumothorax successfully treated with electroconvulsive therapy.

We describe 2 patients with catatonia who developed the complication of pneumothorax, the accumulation of air in the pleural cavity leading to collapse of a lung. Electroconvulsive therapy was safely administered to resolve catatonia, with special attention to managing pneumothorax by insertion of a thoracostomy tube and careful management of ventilation.

Resolution of catatonia by successful seizure induction via electroconvulsive therapy with electrodes applied bilaterally to the parietotemporal region.

Electroconvulsive therapy (ECT) has been shown to be effective in cases of medically intractable mood disorder and schizophrenia. However, some patients receiving ECT have only a short electroencephalographic seizure or no seizure at the maximum stimulus intensity and thus fail to obtain a therapeutic effect. A new treatment option is needed to induce therapeutic seizures in such patients. We report a case of catatonic schizophrenia that was resolved by successful seizure induction by means of ECT with electrodes applied bilaterally to the parietotemporal region after bifrontotemporal ECT failed to induce adequate seizure. We note that parietotemporal ECT can induce therapeutic seizures in patients with a high seizure threshold because more current penetrates the brain due to a decrease in shunted current.

Agitated depression successfully treated with electroconvulsive therapy combined with steroid cover in a patient with Addison's disease.

We report the case of a 70-year-old man with Addison's disease who developed severe agitated depression resulting in life-threatening medical conditions. The depression was treated safely with electroconvulsive therapy (ECT) combined with steroid cover. Administration of steroid cover just before each ECT session may increase safety of the ECT procedure in psychiatric patients with Addison's disease.

Improvement of psychiatric symptoms after electroconvulsive therapy in young adults with intractable first-episode schizophrenia and schizophreniform disorder.

Schizophrenia is a serious psychiatric disorder that develops mainly in young adults. Electroconvulsive therapy (ECT) is known to be effective and safe in patients with schizophrenia with acute psychotic exacerbation. Because of the shortage of systematic studies, we conducted a prospective naturalistic study to examine the short-term effects of acute ECT and its safety in young adults with medically intractable first-episode schizophrenia. Subjects were seven consecutive patients, 15-35 years of age, with first-episode schizophrenia or schizophreniform disorder (Diagnostic and Statistical Manual of Mental Disorders, 4th edition; DSM-IV), who had failed to respond to neuroleptics. The seven patients were treated with a first course of ECT, and their clinical symptoms were evaluated on the basis of the Brief Psychiatric Rating Scale (BPRS) (18 items, rated 0-6) and Global Assessment of Functioning (GAF) Scale. The GAF Scale is presented in DSM-IV as a means of assessing global functioning of a psychiatric patient. Scores range from 1-100; the higher GAF score indicates the higher global functioning. Adverse effects resulting from acute ECT were also evaluated. The total BPRS score 1 week after the final session improved significantly compared to the total pre-ECT BPRS score. The GAF score also improved significantly compared to the pre-ECT GAF score. There were no adverse effects during the acute ECT course, except for mild delirium. We conclude that ECT may be an effective and safe treatment option for young adults with intractable first-episode schizophrenia.

Adjusting the frequency of continuation and maintenance electroconvulsive therapy to prevent relapse of catatonic schizophrenia in middle-aged and elderly patients who are relapse-prone.

The purpose of the present paper was to study the effect of continuation electroconvulsive therapy (ECT) on the prevention of relapse in middle-aged and elderly patients with intractable catatonic schizophrenia. It was found that continuation ECT is efficacious to sustain remission for patients who suffer relapse after response to acute ECT despite continuation neuroleptics. However, three patients suffered relapse during continuation ECT, therefore the effect of adjusting the frequency of continuation ECT and maintenance ECT was investigated in these patients with catatonic schizophrenia who relapsed during continuation ECT. These patients with DSM-IV catatonic schizophrenia who relapsed during continuation ECT were treated with more frequent continuation ECT and subsequent maintenance ECT after response to acute ECT. The patients' Brief Psychiatric Rating Scale (BPRS) scores were prospectively evaluated until relapse. Patients were considered to be relapsers if they had a BPRS score >or=37 for 3 consecutive days. The three patients with catatonic schizophrenia who relapsed during continuation ECT were treated successfully with more frequent continuation ECT and subsequent maintenance ECT. No patient experienced a severe adverse effect from continuation or maintenance ECT. More frequent continuation ECT and maintenance ECT deserves consideration in middle-aged and elderly patients with intractable catatonic schizophrenia who suffer relapse during continuation ECT. Large-scale systematic studies are warranted to investigate the optimum use of continuation and maintenance ECT in patients with catatonic schizophrenia.

Catatonic stupor superimposed on hereditary spinocerebellar degeneration resolved with electroconvulsive therapy.

We report a 58-year-old woman with catatonic stupor superimposed on hereditary spinocerebellar degeneration (SCD) and psychotic depression. The catatonia and psychotic depression resolved with 11 sessions of electroconvulsive therapy (ECT). Early recognition of catatonia during the course of SCD is important for timely administration of ECT.

Epileptic seizures superimposed on catatonic stupor.

PURPOSE: Some patients with nonconvulsive status epilepticus are known to exhibit catatonic stupor. Thus it is necessary to rule out ictal catatonia by electroencephalography in patients with catatonic stupor. However, few reports are available on epileptic seizures superimposed on catatonic stupor. METHODS: We report three cases of epileptic seizures superimposed on psychiatric catatonic stupor without a prominent predisposing factor, including high fever or encephalitis. None of the patients had a personal or family history of neurologic disease, including epilepsy. RESULTS: In all three patients, catatonic stupor persisted after resolution of the epileptic seizures with administration of phenytoin. In two of the three patients, catatonic stupor resolved with electroconvulsive therapy, which caused no marked adverse effects. CONCLUSIONS: Because it is possible that catatonic stupor itself predisposes patients to the development of epileptic seizures, electroencephalographic examinations in patients with catatonic stupor are indispensable for early recognition not only of nonconvulsive status epilepticus but also of epileptic seizures superimposed on catatonic stupor. Electroconvulsive therapy deserves consideration when catatonic stupor persists after resolution of epileptic seizures.

Resolution of SPECT-determined anterior cerebral hypoperfusion correlated with maintenance ECT-derived improvement in residual symptoms in a case of late-life psychotic depression.

A 70-year-old widow with recurrent psychotic depression was successfully treated with maintenance electroconvulsive therapy (ECT) for 4 years up to the present. Anterior cerebral hypoperfusion visualized by single photon emission computerized tomography (SPECT) before ECT persisted (second SPECT study 14 days after the last ECT session) despite a response to the first course of acute ECT. Only mild symptoms remained. Relapse occurred 2 weeks after the post-ECT SPECT study. The hypoperfusion improved after response to a second course of acute ECT (per SPECT 5 days after the last ECT session), and perfusion was normalized after 2-year maintenance ECT (per SPECT 14 days after the last ECT session). The normalization coincided with improvement in depressive symptoms remaining after the second course of acute ECT. We speculate that the effectiveness of maintenance ECT might have been in part the result of the improvement in residual symptoms and that resolution of the persistent anterior hypoperfusion, which might underlie medical refractoriness, illness chronicity, and relapse tendency in late-life depression, might have been associated with the improvement in residual symptoms achieved by maintenance ECT.

Successful use of continuation electroconvulsive therapy in a case of late-onset Leonhard's confusion psychosis.

A 56-year-old married woman with late-onset Leonhard's confusion psychosis was treated successfully with acute electroconvulsive therapy (ECT) after failing to respond to antidepressants, neuroleptics, and benzodiazepines. Symptoms relapsed within 1 year despite the combined use of olanzapine and paroxetine. The patient responded to a second course of acute ECT, but a second relapse occurred within 3 months despite her use of olanzapine and paroxetine. The symptoms resolved with continuation ECT and lithium combined with paroxetine after response to a third course of acute ECT. To date, relapse has been prevented for 2 years. Continuation ECT and lithium combined with paroxetine after response to acute ECT may be effective in maintaining remission of Leonhard's confusion psychosis.

Continuation electroconvulsive therapy for relapse prevention in middle-aged and elderly patients with intractable catatonic schizophrenia.

The authors have previously studied the short-term effect of the first acute electroconvulsive therapy (ECT) course (phase 1 study) on intractable catatonic schizophrenia and the 1-year relapse rate after response to the acute ECT (phase 2 study) in middle-aged and elderly patients. Results indicated that, although acute ECT has an excellent short-term effect, the 1-year relapse rate after response to acute ECT is high despite the use of continuation neuroleptics. In the present prospective study the effect was explored of continuation ECT with neuroleptics on the prevention of relapse after response to a second acute ECT course in the relapsed participants of the phase 2 study. The present study included seven consecutive patients > 45 years of age with catatonic schizophrenia (Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) who relapsed (despite the use of neuroleptics) within 1 year after response to the first acute ECT course, and then responded to the second acute ECT course. The patients were given continuation ECT combined with neuroleptics; four ECT sessions at weekly intervals, then four ECT sessions every 2 weeks, then three ECT sessions every 4 weeks. Clinical symptoms were evaluated by means of the Brief Psychiatric Rating Scale (BPRS) weekly for 48 weeks or until relapse. Relapse was defined as a BPRS score of at least 37 for 3 consecutive days. Three out of the seven patients (42.9%) had a sustained response to ECT during the 1-year follow-up period. In the seven patients the probability of relapse within 1 year under treatment with neuroleptics alone (phase 2 study) was statistically higher than that under continuation ECT combined with neuroleptics (present study). No statistical differences were seen between the phase 2 study and the present study in the severity of psychiatric symptoms, global social function, the number of acute ECT sessions or the dosage of neuroleptics. No patient experienced a severe cognitive or physical adverse effect resulting from continuation ECT. Continuation ECT with neuroleptics is an efficacious and safe treatment for maintaining a response in middle-aged and elderly patients with intractable catatonic schizophrenia who have relapsed after a positive response to acute ECT despite the use of continuation neuroleptics.
