Research

Overview

Dr. Ptomey's primary research focus is the promotion of weight management and physical activity in individuals with intellectual and developmental disabilities including Down syndrome. This population is undeserved and at an increased risk of obesity and its related co-occurring conditions, including Alzheimer's Disease. There is minimal research looking at strategies to improve diet, physical activity, and weight management in individuals with IDD. Dr. Ptomey has completed the largest and longest weight management and physical activity studies for this population, and her work has informed informed several healthcare and policy recommendations.

Dr. Ptomey's secondary research focus is the prevention of Alzheimer's Disease in adults with Down syndrome. She recently completed the first long-term exercise trial examining the impact of exercise on factors related to Alzheimer's Disease in adults with Down syndrome, and is currently a site PI for the NIH funded Alzheimer's Biomarker Consortium-Down syndrome (U19 AG068054) and Clinical Trials to Prevent Alzheimer's Disease in Down Syndrome (R61 AG066543) longitudinal cohorts.
