Down Syndrome Regression Disorder

The following information was taken from the NDSS website:
Quote, “Down syndrome regression disorder (DSRD), also referred to as regression, is a rare but serious disorder that occurs in some adolescents and young adults with Down syndrome. Regression is used to describe the loss of skills an individual has previously learned. These skills can be daily living, language, movement, or social skills. The loss is often sudden and occurs over a period of weeks to months. Since DSRD may be caused by a variety of factors, the first priority is to determine the most likely cause. Individuals who are younger than 10 years or older than 30 years are very rarely diagnosed with DSRD."
