 Kenneth H.  Fischbeck  M.D., Senior Investigator

Dr. Fischbeck received A.B. and A.M. degrees from Harvard University and an M.D. degree from Johns Hopkins. After a medical internship at Case Western Reserve University and a neurology residency at the University of California in San Francisco, he did postdoctoral research on muscular dystrophy at the University of Pennsylvania. In 1982 he joined the faculty in the Neurology Department at the University of Pennsylvania Medical School. In 1998 he came to the NINDS as Chief of the Neurogenetics Branch. He received the Cotzias Award from the American Academy of Neurology and was elected to the Institute of Medicine of the National Academy of Sciences. His laboratory is studying the mechanisms of hereditary neurological and neuromuscular disorders, particularly the polyglutamine expansion neurodegenerative diseases.

Research Interests

The purpose of the Neurogenetics Branch is to investigate the causes of hereditary neurological diseases, with the goal of developing effective treatments for these disorders. Particular areas of research interest in the Fischbeck lab include the polyglutamine expansion diseases (Huntington's disease, Kennedy's disease, and spinocerebellar ataxia), spinal muscular atrophy, Charcot-Marie-Tooth disease, muscular dystrophy, hereditary motor neuron disease, and Friedreich's ataxia. The disease mechanisms are studied in cell culture and other model systems. A genetic outreach program is intended to identify and characterize patients and families with hereditary neurological diseases. A trial of idebenone treatment for Friedreich's ataxia was recently completed, and a trial of dutasteride treatment for Kennedy's disease is currently in progress. Efforts are also underway to develop new treatments for spinal muscular atrophy and muscular dystrophy.
