Dr. George Capone is a research scientist and director of the Down Syndrome Clinic and Research Center (DSCRC) at Kennedy Krieger Institute and is also an associate professor of pediatrics at the Johns Hopkins University School of Medicine.

Biographical Sketch: 

Dr. Capone attended college at Wesleyan University and worked as a research assistant at the Dana Farber Cancer Institute in Boston before obtaining his medical degree from the University of Connecticut in 1983. After a residency and fellowship in pediatrics at the Children's Hospital Medical Center in Cincinnati, Dr. Capone came to Baltimore in 1988 to pursue a fellowship in neurobiology research at Johns Hopkins. Dr. Capone currently serves as the director of Kennedy Krieger Institute's Down Syndrome Clinic and Research Center (DSCRC), and is an attending physician on the institute's comprehensive rehabilitation unit.

Research Summary: 

Down syndrome is a genetic disorder that occurs in approximately 1 in 733 live births. It is caused most often by an abnormality during cell division in gamete formation called nondysjunction. As a result, the fertilized egg will contain three copies of chromosome 21. The extra chromosome interferes with normal growth and development.

Dr. Capone and his colleagues are committed to research that explores the neurobiologic basis of cognitive impairment and co-morbid neurobehavioral and psychiatric disorders associated with Down syndrome.

Current Research Projects:

  • A multi-center, double-blind placebo study in collaboration with Duke University testing the usefulness of an FDA approved drug, Rivastigmine, on memory and language function in children with Down syndrome ages 10-17 years. Cathleen Weadon, Research Coordinator, (443) 923-9140
  • A multi-center pilot study, in collaboration with Johns Hopkins University for children with Down syndrome ages 7-17 years, to determine the usefulness of computer-based testing to measure visual memory and movement. Some standardized testing will also be performed, and your child's test results will be made available to you. Lisa Toole, Research Coordinator (443) 923-2953.
  • Roche Pharmaceuticals is sponsoring a study at Kennedy Krieger Institute and the Johns Hopkins University for adults with Down syndrome between 18 and 30 years of age. The purpose is to study the safety and tolerability of a new drug that have been developed to improve attention and memory. Carrie Blout, MS, CGC, (410) 502-7535
