Mahlon DeLong obtained his medical degree from Harvard Medical School, completed his internship at Boston City Hospital and his residency training at Johns Hopkins Hospital in Baltimore. He previously worked at the National Institute of Mental Health in Bethesda. Dr. DeLong received his medical license in 1980 and began working as a neurologist and researcher at the Johns Hopkins University. Since 1990, he has worked at Emory University, where he is the William Patterson Timmie Professor of Neurology.
Dr. DeLong has played a major role in clarifying the functional organization of the basal ganglia and the role of these structures in movement and the pathophysiology of movement disorders such as Parkinson's disease. Based on anatomical and physiological evidence, Dr. DeLong and colleagues proposed a major revision of the prevailing view that the basal ganglia funneled input from all cortical areas to the motor cortex. In the proposed scheme the basal ganglia are viewed as components of a family of parallel cortical-subcortical circuits subserving motor, oculomotor, associative and limbic functions. This view provided a substrate for a far wider role in motor and non-motor behavior and a mechanism whereby pathologic change in specific circuits could account for many of the motor, cognitive, behavioral and emotional disturbances seen in movement disorders such as Parkinson’s disease as well as in the neuropsychiatric disorders such as Tourette’s syndrome and Obsessive Compulsive Disorder.
Dr. DeLong’s studies have contributed to the development of new and more effective surgical approaches for the treatment of movement disorders and he and his colleagues have carried out key controlled clinical trials for the surgical treatment of movement disorders.
Among numerous awards, Dr. DeLong received a Javitz Neuroscience Investigator Award from the NINDS for his research and the Alfred E. Springer Award by the American Parkinson’s Disease Association, the Edward B. Henderson Lecture Award, by the American Geriatrics Society, the Schneider Lecture by the American Association of Neurological Surgeons, and the American Academy of Neurology Wartenburg Award. Dr. DeLong was selected as the first recipient of the Deans Distinguished Faculty Award and Lecturer at Emory and received the Parkinson’s Disease Foundation’s 50th Anniversary Award for his contributions to the field. Dr. DeLong recently received the 2008 Movement Disorders Society Lifetime Achievement Award and the 2009 American Academy of Neurology Movement Disorders Research Award. His most recent award was the 2014 Breakthrough Prize in Life Sciences, which recognizes excellence in research aimed at curing intractable diseases and extending life for defining the interlocking circuits in the brain that malfunction in Parkinson's disease.
He is recognized by Castle-Connolly as one of the Top Doctors in Neurology for the treatment of movement disorder.
