There is no cure for Down syndrome. However, some of the clinical manifestations can be treated. For example, heart defects and duodenal atresia can often be corrected with surgical repair. It was common only a few decades ago to enforce involuntary sterilization of individuals with Down syndrome. Additionally, it used to be common for these patients to be institutionalized. Today, involuntary sterilizations are illegal and most patients reside with their families. Many community support groups exist to help families deal with the emotional effects and to help plan for the affected individuals future. In general, Down syndrome people tend to be easy going and good natured.
