Dr. Yakeel Quiroz’s research focuses on identifying early cognitive and biological markers of Alzheimer\u2019s disease and uncovering mechanisms that support cognitive resilience and delay dementia onset. For over 20 years, she has studied Colombian families with early-onset autosomal dominant Alzheimer\u2019s disease (ADAD) caused by mutations in the Presenilin-1(PSEN1) gene. With near-complete penetrance and symptom onset in the forties, these families offer a rare opportunity to track the biological trajectory of AD from preclinical to clinical stages\u2014and to investigate protective mechanisms in individuals who remain cognitively resilient despite carrying the mutation.<\/p>\n Dr. Quiroz leads multiple NIH-funded studies, including the Colombia-Boston (COLBOS) biomarker study of autosomal-dominant Alzheimer\u2019s disease, the Boston Latino Aging Study (BLAST), and the Healthy Aging and Resilient Brain Study on genetic modifiers of cognitive resilience. She is also a Co-Investigator on the Harvard Aging Brain Study (HABS) and the Alzheimer\u2019s Clinical Trials Consortium (ACTC).
