New research from USC has uncovered a previously unknown genetic risk factor for Alzheimer's disease and related dementias. The study provides insights on how these conditions, and other diseases of aging, might one day be treated and prevented. sheds new light on the protective role of a naturally occurring mitochondrial peptide, known as humanin

In his study, Dr. Kelvin Yen of the Leonard Davis School of Gerontology highlighted the importance of humanin, a mitochondrial gene that could delay Alzheimer's disease and other cognitive decline.
