    OBJECTIVE: The Prolonging Remission in Depressed Elderly (PRIDE) study evaluated the efficacy of right unilateral ultrabrief pulse electroconvulsive therapy (ECT) combined with venlafaxine for the treatment of geriatric depression.

    METHOD: PRIDE was a two-phase multisite study. Phase 1 was an acute course of right unilateral ultrabrief pulse ECT, combined with open-label venlafaxine at seven academic medical centers. In phase 2 (reported separately), patients who had remitted were ...

    BACKGROUND: Electroconvulsive therapy (ECT) is an effective treatment for major depression. Optimising efficacy and minimising cognitive impairment are goals of ongoing technical refinements.

    AIMS: To compare the efficacy and cognitive effects of a novel electrode placement, bifrontal, with two standard electrode placements, bitemporal and right unilateral in ECT.

    METHOD: This multicentre randomised, double-blind, controlled trial (NCT00069407) was carried out from 2001 to 2006. A total ...

    OBJECTIVE: Up to 70% of patients with treatment-resistant schizophrenia do not respond to clozapine. Pharmacological augmentation to clozapine has been studied with unimpressive results. The authors examined the use of ECT as an augmentation to clozapine for treatment-refractory schizophrenia.

    METHOD: In a randomized single-blind 8-week study, patients with clozapine-resistant schizophrenia were assigned to treatment as usual (clozapine group) or a course of bilateral ECT plus clozapine ...

    OBJECTIVE: The randomized phase (phase 2) of the Prolonging Remission in Depressed Elderly (PRIDE) study evaluated the efficacy and tolerability of continuation ECT plus medication compared with medication alone in depressed geriatric patients after a successful course of ECT (phase 1).

    METHOD: PRIDE was a two-phase multisite study. Phase 1 was an acute course of right unilateral ultrabrief pulse ECT, augmented with venlafaxine. Phase 2 compared two randomized treatment arms: a ...

    BACKGROUND: Although electroconvulsive therapy (ECT) has been shown to be extremely effective for the acute treatment of major depression, it has never been systematically assessed as a strategy for relapse prevention.

    OBJECTIVE: To evaluate the comparative efficacy of continuation ECT (C-ECT) and the combination of lithium carbonate plus nortriptyline hydrochloride (C-Pharm) in the prevention of depressive relapse.

    DESIGN: Multisite, randomized, parallel design, 6-month trial performed ...

    INTRODUCTION: Patients with Major Depressive Disorder (MDD) referred for electroconvulsive therapy (ECT) have poorer Health Related Quality of Life (HRQOL), compared with other patients with MDD, but ECT is associated with significant and durable improvement in HRQOL. However, no prior research has focused exclusively on elderly patients with MDD receiving ECT.

    METHODS: HRQOL data from 240 depressed patients over the age of 60 was measured with the Medical Outcomes Study Short Form 36 ...

    Data regarding the co-occurrence of anxiety symptoms or syndromes in schizophrenia is scant. Hierarchical assumptions embedded in diagnostic systems and methodologic difficulties hamper the development of studies on accessory symptomatology outside of the core positive-negative-disorganized symptoms. Recent studies have repeatedly challenged these assumptions by presenting data on comorbid disorders in schizophrenia. We review the current knowledge about anxiety comorbidity in ...

    One barrier to interpreting past studies of cognition and major depressive disorder (MDD) has been the failure in many studies to adequately dissociate the effects of MDD from the potential cognitive side effects of selective serotonin reuptake inhibitors (SSRIs) use. To better understand how remediation of depressive symptoms affects cognitive function in MDD, we evaluated three groups of subjects: medication-naïve patients with MDD, medicated patients with MDD receiving the SSRI ...

    OBJECTIVES: We sought to review the literature on the use of combined antipsychotic medications and electroconvulsive therapy (ECT) for the treatment of schizophrenia, with regard to efficacy, side effects, and ECT technique.

    METHODS: A computerized search of the literature published from 1980 to 2004 was conducted on Medline and PsychoInfo using the words schizophrenia, antipsychotic, neuroleptic, psychotropic, and ECT. Only studies including patients with the diagnosis of schizophrenia ...

    OBJECTIVE: To compare the relative efficacy of electroconvulsive therapy (ECT) in psychotic and nonpsychotic patients with unipolar major depression.

    METHODS: The outcome of an acute ECT course in 253 patients with nonpsychotic (n = 176) and psychotic (n = 77) unipolar major depression was assessed in the first phase of an ongoing National Institute of Mental Health-supported four-hospital collaborative study of continuation treatments after successful ECT courses. ECT was administered ...

    BACKGROUND: Deep brain stimulation (DBS) of the subcallosal cingulate white matter has shown promise as an intervention for patients with chronic, unremitting depression. To test the safety and efficacy of DBS for treatment-resistant depression, a prospective, randomised, sham-controlled trial was conducted.

    METHODS: Participants with treatment-resistant depression were implanted with a DBS system targeting bilateral subcallosal cingulate white matter and randomised to 6 months of active ...

    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. ...

    PURPOSE OF REVIEW: ECT remains an important, yet underutilized, treatment for schizophrenia. Recent research shows that medication-resistant patients with schizophrenia, including those resistant to clozapine, respond well to ECT augmentation. The purpose of this article is to review recent studies of the use of ECT in the treatment of schizophrenia.

    RECENT FINDINGS: We performed an electronic database search for articles on ECT and schizophrenia, published in 2017. The main themes of ...
