About Me

James F. Sumowski, Ph.D. is an Associate Professor of Neurology at Mount Sinai and the clinical neuropsychologist at the Corinne Goldsmith Dickinson Center for Multiple Sclerosis (MS). Dr. Sumowski is an expert on cognition in persons with MS, and he introduced the concept of “reserve” against cognitive decline in MS: the observation that genetic and environmental factors can moderate deleterious effects of disease on functional outcomes (representative article: Sumowski et al., Neurology 2014). The Sumowski Laboratory works to advance understanding and improvement of functional outcomes. Toward this end, Dr. Sumowski is the PI of a large prospective National Institutes of Health (NIH / NICHD) R01 grant to identify modifiable risk and protective factors linked to cognitive decline, which will inform future interventions.

Dr. Sumowski is a leader in the field. He recently led an international group of MS experts toward a joint statement of knowledge gaps, obstacles, and research priorities for the field of cognition in persons with MS (Sumowski et al., Neurology 2018). In addition to outlining several specific recommendations for research and clinical practice, the statement highlights the critical need to develop testable and biologically plausible models of cognitive decline due to MS, which will lay the groundwork for much-needed evidence-based rehabilitation.

Dr. Sumowski is Co-Director of the Postdoctoral Fellowship in Clinical Neuropsychology and Clinical Research at Mount Sinai, which will prepare trainees for careers as clinician-researchers in academic medical center settings. He is also an Adjunct Professor at Teachers College, Columbia University, where he serves as dissertation mentor for Ph.D. candidates.

Dr. Sumowski offers telemedicine appointments when appropriate.  Please call his office to schedule a video visit.
