Dr. Breitner has devoted his career to the study of Alzheimer’s disease (AD), its risk factors, and their implications for its prevention. Although an expert clinician, he is better known as a researcher. His early work on familial aggregation in AD evolved to twin studies of heritability and environmental risk factors. He then founded the Cache County Study of Memory in Aging, a longitudinal investigation of genetic and environmental antecedents of AD, which has produced over 100 scientific papers. More recently he was Chair of the randomized placebo-controlled Alzheimer’s Disease Anti-inflammatory Prevention Trial (ADAPT) that evaluated two nonsteroidal anti-inflammatory drugs for primary prevention of AD in healthy elderly. As that trial winds down, he recently joined the McGill faculty to establish the new StoP-AD Centre at the Douglas. This Centre is devoted to identification and quantitation of AD markers in the pre-symptomatic stage of the disease, and to preliminary testing of experimental strategies for that may prevent progression of pre-symptomatic disease to dementia. Dr. Breitner is has mentored more than 15 individuals who have gone on to tenure-track academic positions, nine of these whom have independent NIH funding, 3 are now Chairs and one the Executive Editor of a leading Alzheimer’s disease journal.
