Sci. Aging Knowl. Environ., 13 August 2003 NEWS FOCUSChasing 100Ten years ago, geriatrician Thomas Perls couldn't understand why his 100-year-old patients were never in their rooms. He started looking into why, and he hasn't stopped sinceIngfei Chen http://sageke.sciencemag.org/cgi/content/full/sageke;2003/32/nf15Abstract: When geriatrician Thomas Perls treated his first centenarians in 1992, he expected to find them debilitated by illness and dementia. But he instead discovered that some extremely old individuals can escape Alzheimer's disease and other age-related disorders. In 1994 at Harvard Medical School, he started the New England Centenarian Study (NECS), a survey that has grown into an international investigation with data on 1000 centenarians from the United States, Canada, Germany, Japan, and Australia. Now based at the Boston University School of Medicine, the study has toppled several misconceptions about extremely old age and suggests a genetic basis to exceptional longevity. The work led to the founding of a biotech company called Centagenetix, which subsequently merged with Elixir Pharmaceuticals. Citation: I. Chen, Chasing 100. Sci. SAGE KE 2003 (32), nf15 (2003).
