James G. Herndon, PhD, MPH

Yerkes Researcher (Retired 2013)


James G. Herndon, PhD, MPH, completed his undergraduate studies at LaSalle College before receiving his master’s of public health degree and doctorate from Emory University. Dr. Herndon studies cognitive decline, the loss of the ability to think and remember, which is one of the most feared ailments that occur with aging. This type of ailment can be so serious in some people that they cannot deal effectively with matters of everyday life, and they may even lose the ability to converse normally or recognize people who are important in their lives. An important goal of Dr. Herndon’s research is to understand why some individuals age well in terms of cognitive ability while others have serious behavioral pathology in advancing age.

As part of a $10 million grant from the National Institute on Aging, Dr. Herdnon’s lab is studying longitudinal changes that occur in normally aging women, women with Alzheimer’s disease and women with mild cognitive impairment, as well as female chimpanzees and rhesus macaques. Drawing upon neuroimaging, cognitive and motor testing, and endocrine status, this study is giving insight into the biological basis of age-related functional decline and into the factors that can influence healthy aging.

Dr. Herndon collaborates with a number of researchers at Yerkes, including Drs. Todd Preuess, Lary Walker, Xiaodong Zhang and Yerkes Director Dr. Stuart Zola.
