Between September 1st, 1994, and the end of August, 1995, 3% of all inpatients (21 of 731) were treated with electroconvulsive therapy (ECT) at the Department of General Psychiatry at the University Hospital for Psychiatry in Vienna. These patients suffered from psychotic and/or therapy-resistant depression (n = 15), therapy-resistant schizoaffective psychosis (n = 3), and catatonic schizophrenia (n = 3). ECT was administered in short-time anaesthetised and muscle relaxed patients. On average, each patient was treated with ECT on 9 non-consecutive days. As a rule, electrodes were placed unilaterally over the non-dominant hemisphere at the beginning. In four cases electrodes were placed bifronto-temporally. To be considered as effective the seizure had to last for at least 25 s. In shorter seizure duration ECT was repeated up to a maximum of three times in one session. With this procedure a reduction in clinical global impressions of -3.7 points was achieved in ECT-treated patients, who had been considered to be "severely" to "most severely" ill according to CGI before starting ECT. ECT proved to be effective for treating severe depression and catatonic schizophrenia, with only minor and reversible side effects. For establishing a favorable relation between good clinical outcome and remarkable few side effects, the following factors seem to be of importance, in accordance with the literature: (1) application of biphasic short-impulse stimuli in anaesthetised and muscle relaxed patients; (2) measurement of static impedance to avoid high skin impedance and short circuits. (3) at the beginning of each ECT series unilateral electrode placement over the non-dominant hemisphere; (4) ECT three times weekly on non-consecutive days.

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.

Subacute sclerosing panencephalitis (SSPE) is a progressive disease caused by wild-type measles virus leading to premature death. Early diagnosis may help in medical interventions and counseling. The aim of this study was to ascertain diagnostic errors and their possible causes. Retrospective case record analysis of patients with subacute sclerosing panencephalitis, evaluated over a 10-year period, was performed. The following data were analyzed: initial symptoms and diagnosis, interval between onset of symptoms to diagnosis, and implications of delayed diagnosis. Among the 307 patients evaluated, initial diagnosis by various health care professionals was other than subacute sclerosing panencephalitis in 242 patients (78.8%). These included seizures, absence seizures, metachromatic leukodystrophy, Schilder's disease, cerebral palsy, hemiparkinsonism, Wilson's disease, vasculitis, spinocerebellar ataxia, motor neuron disease, nutritional amblyopia, tapetoretinal degeneration, catatonic schizophrenia, and malingering, among others. The interval between precise diagnosis and first reported symptom was 6.2 +/- 11.3 months (range, 0.2-96 months; median, 3 months). Forty-four patients (14.3%) who had symptoms for more than 1 year before the precise diagnosis had a protracted course as compared to the rest of the cohort ( P = .0001). Early and accurate diagnosis of subacute sclerosing panencephalitis needs a high index of suspicion.

Cerebral folate deficiency presents during infancy with irritability, deceleration of head growth, seizures, and progressive cognitive and motor impairment. Although low serum folate levels have been found in patients with schizophrenia, we describe the first case of cerebral folate deficiency presenting as catatonic schizophrenia. A 13-year-old previously healthy boy presented to our hospital with a 17-month history of schizophrenic symptoms with progressively worsening catatonia. On admission, he demonstrated near-complete mutism, frequent enuresis and encopresis, and severe psychomotor retardation. Our initial diagnostic evaluations, including brain magnetic resonance imaging, electroencephalogram, and routine metabolic tests, were normal. A lumbar puncture done to look for neurotransmitter defects or cerebral folate deficiency revealed low levels of 5-methyltetrahydrofolate (31 nmol/L; reference range, 40-150 nmol/L). He also had elevated titers of folate receptor-blocking antibodies. He was treated for the next 9 months with 5-formyltetrahydrofolate (folinic acid), but his catatonia was unchanged.

Inducing adequate therapeutic seizures during electroconvulsive therapy (ECT) is sometimes difficult due to a high seizure threshold, even at the maximum stimulus charge. Previous studies have demonstrated that seizure threshold is lower in patients treated with right unilateral ultrabrief pulse (RUL-UBP) ECT than in those treated with bilateral or brief pulse (BL-BP) ECT. Therefore, switching to RUL-UBP ECT may be beneficial for patients in whom seizure induction is difficult with conventional ECT. In the present report, we discuss the case of a patient suffering from catatonic schizophrenia in whom BL-BP ECT failed to induce seizures at the maximum charge. However, RUL-UBP ECT successfully elicited therapeutic seizures and enabled the patient to achieve complete remission. This case illustrates that, along with other augmentation strategies, RUL-UBP ECT represents an alternative for seizure induction in clinical practice.
