Rett Syndrome (RTT) is a unique neurodevelopmental disorder that begins to show its affects in infancy or early childhood. It is seen almost exclusively in females, although it can occur rarely in boys. It is found in all racial and ethnic groups throughout the world. Age of OnsetThe age when RTT begins and the severity of different symptoms may vary. The child with RTT is usually born healthy and shows an early period of apparently normal or near normal development until 6-18 months of life, when there is a slowing down or stagnation of skills. A period of regression then follows when the child loses communication skills and purposeful use of her hands and slowing of the normal rate of head growth become apparent. Soon, stereotyped hand movements and gait disturbances are noted. Other problems may include disorganized breathing patterns which occur when she is awake, and seizures. There may be a period of isolation or withdrawal when the child is irritable and cries inconsolably. Over time, motor problems may increase, while interaction and communication, especially with eye gaze, seizures, and irregular breathing may improve. Most individuals with RTT require maximum assistance with every aspect of daily living. * This information has been adapted from www.rettsyndrome.org |
