Dr. Worley’s research focuses on the molecular basis of learning and memory. He is examining biomarkers of molecular pathways essential for cognitive function that are altered in mild cognitive impairment and AD dementia. This includes NPTX2, which plays a central role in adaptive inhibitory circuit function, and mTORC1, a signaling complex that integrates multiple aspects of metabolism, energy homeostasis and growth factor signaling. The goal is to determine whether these brain proteins are altered early in the disease course and are related to symptom onset.
