Primary objective was to evaluate baseline characteristics for catatonic patients treated with and without electroconvulsive therapy (ECT). We also studied the trends of ECT utilization in catatonia patients. The Nationwide Inpatient Sample data were used to compare patients and hospital-level characteristics between catatonic patients treated with and without ECT in the United States. Multivariate and trend analysis were performed. Electroconvulsive therapy was performed in 8.3% in patients with the diagnosis of catatonia (n = 24,311; mean age, 43.1; 38% White; 52.1% male). Racially, more patients in the ECT group were White (47% vs 38%) and had a comorbid diagnosis of major depressive disorder. In the multivariate analysis, the odds of receiving ECT was more with increase in age (P = 0.007). Urban area hospitals had 3 times higher odds of receiving ECT (P = 0.001) compared with rural hospitals. The odds of receiving ECT for catatonia were the highest for large bed hospitals compared with small/medium size (P < 0.001). In the trend analysis, catatonia patients undergoing ECT decreased initially from 7.0% in 2002 to 2005 to 5.2% in 2006 to 2009. After that, there was an upward trend with 10.6% patients undergoing ECT in the quarter 2014 to 2017. There was an upward trend in ECT utilization for catatonic patients with comorbid bipolar disorders and psychotic disorders. Electroconvulsive therapy is underutilized for catatonia treatment in the United States. White catatonic patients are most likely to get ECT at an urban large bed hospital. In recent years, there is an upward trend in the use of ECT. Additional controlled clinical trials are warranted.

In schizophrenia, negative symptoms account for a substantial amount of the comorbidity resulting in poor performance in social interaction, interpersonal relationships, economic functioning, and recreational activities. Research has implicated hypofrontality in the pathogenesis of negative symptoms of schizophrenia. Conventional transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex has attracted significant interest as an add-on treatment for negative symptoms in schizophrenia. High-definition tDCS (HD-tDCS), an optimized form of tDCS, has the potential for more focalized neuromodulation. Hence, we aimed to evaluate the efficacy of HD-tDCS over the left dorsolateral prefrontal cortex in the improvement of negative symptoms in schizophrenia. Fourteen patients with schizophrenia with predominantly negative symptoms were enrolled for this pilot, randomized, sham-controlled, double-blind trial. Each participant received 10 sessions of HD-tDCS at 2 mA for 20 minutes twice daily over 5 days. Negative symptoms were assessed with the Scale for Assessment of Negative Symptoms and Positive and Negative Syndrome Scale for Schizophrenia. The Calgary Depression Scale for Schizophrenia was used to rule out depressive symptoms. Assessments were carried out at baseline and at 2 weeks. The improvement in negative symptoms in the active group was statistically significant at P value of 0.05 as compared with the sham group. These results suggest that HD-tDCS may lead to improvement in negative symptoms of schizophrenia. Its use as an adjunct to pharmacological treatment of negative symptoms may be worth considering.

The primary aim of this study was to describe a Portuguese nationwide epidemiological perspective on the use of electroconvulsive therapy (ECT) in hospitalized psychiatric patients. The secondary aims of the study were to characterize clinical and sociodemographic trends of hospitalized patients treated with ECT. A retrospective-observational study was conducted using an administrative database gathering every registered Portuguese public hospital hospitalizations from 2008 to 2015. We selected all hospitalizations with a procedure code 94.27 (Other electroshock therapy) defined by the International Classification of Diseases version 9, Clinical Modification. Variables included birth date, sex, address, primary and secondary diagnoses, admission/discharge date, length of stay, and discharge status from each single hospitalization episode. We also calculated Portugal's inpatient ECT prevalence rate (iP%). There were a total of 879 registered hospitalizations with ECT within the 8-year period of this study. Most occurred in female patients (53.4%), belonging to the age group of 51 to 70 years old, with a mean age of 50.5 years. The median length of stay was 43.0 days with an interquartile range of 27.0 to 68.0. The most frequent primary diagnosis was major depressive disorder, recurrent episode, representing 19.6% of all hospitalizations. The iP% for the study period was 0.71%. In Portugal, most of the patients who received ECT were women above middle age, and depressive disorders were the most common indication. Portugal's iP% represents a low rate when compared with other European countries, which might indicate an underutilization of ECT in Portuguese psychiatric hospitals.

Electroconvulsive therapy (ECT) is a well-established treatment for mood disorders in younger adults and has been consistently shown to be safe and effective in unipolar depression in older adults. However, data on this treatment in older adults with bipolar disorder are limited. In this retrospective study, we report outcomes from all cases of older adults with bipolar depression who received ECT from a large academic institution over a 7-year period. We retrospectively identified all patients 65 years and older with bipolar depression who were treated with ECT over a 7-year period. Patients receiving ECT for an episode of bipolar depression were included in the study based on chart review and availability of documented outcome measures. Primary outcomes were changes in Montreal Cognitive Assessment and Clinical Global Impressions scores. We identified 34 patients meeting inclusion criteria. Collectively, patients had statistically significant improvement in Montreal Cognitive Assessment scores and reductions in Clinical Global Impressions severity scores after treatment.
