Neurocognitive Effects of Combined Electroconvulsive Therapy (ECT) and Venlafaxine in Geriatric Depression: Phase 1 of the PRIDE Study.

Abstract

OBJECTIVE:There is limited information regarding the tolerability of electroconvulsive therapy (ECT) combined with pharmacotherapy in elderly adults with major depressive disorder (MDD). Addressing this gap, we report acute neurocognitive outcomes from Phase 1 of the Prolonging Remission in Depressed Elderly (PRIDE) study. METHODS:Elderly adults (age ≥60) with MDD received an acute course of 6 times seizure threshold right unilateral ultrabrief pulse (RUL-UB) ECT. Venlafaxine was initiated during the first treatment week and continued throughout the study. A comprehensive neurocognitive battery was administered at baseline and 72 hours following the last ECT session. Statistical significance was defined as a two-sided p-value of less than 0.05. RESULTS:A total of 240 elderly adults were enrolled. Neurocognitive performance acutely declined post ECT on measures of psychomotor and verbal processing speed, autobiographical memory consistency, short-term verbal recall and recognition of learned words, phonemic fluency, and complex visual scanning/cognitive flexibility. The magnitude of change from baseline to end for most neurocognitive measures was modest. CONCLUSION:This is the first study to characterize the neurocognitive effects of combined RUL-UB ECT and venlafaxine in elderly adults with MDD and provides new evidence for the tolerability of RUL-UB ECT in an elderly sample. Of the cognitive domains assessed, only phonemic fluency, complex visual scanning, and cognitive flexibility qualitatively declined from low average to mildly impaired. While some acute changes in neurocognitive performance were statistically significant, the majority of the indices as based on the effect sizes remained relatively stable.

Sarah Hollingsworth Lisanby

Professor Emeritus of Psychiatry and Behavioral Sciences

Sarah Hollingsworth “Holly” Lisanby, MD, is an experienced translational researcher and innovator of neuromodulation technologies to study and treat psychiatric disorders. Dr. Lisanby is Director of the Division of Translational Research at NIMH, which funds research on the discovery of preventions, treatments, and cures for mental illness across the lifespan.  She is Founder and Director of the Noninvasive Neuromodulation Unit in the NIMH Intramural Research Program, a multi-disciplinary clinical research program specializing in the innovation of new brain stimulation tools to measure and modulate neuroplasticity to improve mental health.  Dr. Lisanby is former Chair of the Duke Department of Psychiatry & Behavioral Sciences, and JP Gibbons Endowed Professor at Duke University.  She founded and directed both the Duke and the Columbia University Divisions of Brain Stimulation, where she built interdisciplinary research programs specializing in the convergence of Psychiatry, Neuroscience and Engineering. She co-led the NIH BRAIN Initiative Team focused on large-scale neural recording and modulation devices. Dr. Lisanby has been principal investigator on a series of federally funded grants on the development of novel neuromodulation technologies, including the rational design of magnetic and electrical seizure therapies.  Her team pioneered magnetic seizure therapy (MST) as a novel depression treatment from the stages of animal testing, first-in-human, and international clinical trials.  She led a series of studies involving transcranial magnetic stimulation, electroconvulsive therapy (ECT), MST, vagus nerve stimulation, and deep brain stimulation. She has received numerous international recognitions, including the Max Hamilton Memorial Prize of the Collegium Internationale Neuro-Psychopharmacologicum, the Gerald Klerman Award from the National Depression and Manic Depression Association, and the Eva King Killam Research Award from the American College of Neuropsychopharmacology.  She has been a member of the NIMH Board of Scientific Counselors. Dr. Lisanby served on the FDA Neurological Devices Advisory Panel and has held key leadership positions with numerous professional associations, including serving as President for the Association for Convulsive Therapy/International Society of Neurostimulation, and the International Society for Transcranial Stimulation, and Chair of the American Psychiatric Association Task Force to Revise the Practice on ECT.
