Regression3
  • Rett Syndrome (RTT) is a neurodevelopmental disorder characterized by developmental regression, motor dysfunction, and cognitive deficits. (upenn.edu)

(hindawi.com)
  • Following this initial clinical exposure to RTT, investigations began to intensify, spurred by efforts of Hugo Moser to convene an international meeting at Johns Hopkins Medical School in 1985 and the subsequent creation of the International Rett Syndrome Association (IRSA) through the leadership of three parents, Kathy Hunter, Gail Smith, and Jane Brubaker.
