Abstract

This pilot study will develop advanced deep learning neural networks to analyze Clock-Drawing Test images to predict dementia diagnosis. The pilot will draw upon Medicare claims linked with a large, publicly available repository of clock images from the 2011-2019 National Health and Aging Trends Study, a panel study of Medicare beneficiaries ages 65 and older.
