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.
Dr. Capone’s current research projects include:
- 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.
- 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.
- 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.

Patient Ratings & Comments
The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
