Williams Syndrome Follow-up

Updated: Jan 14, 2015
 

Further Outpatient Care

School performance, hyperactivity, and the child's eventual role in society are long-term issues that need to be addressed on an ongoing basis.

Anticipatory guidance is essential to help parents prepare for future needs of children with Williams syndrome.

Prognosis

Consider the progressive nature of medical problems in Williams syndrome, including vascular stenosis, hypertension, and joint contractures.

Medical complications may occur, especially related to the cardiovascular system. However, most individuals with Williams syndrome are healthy and lead active full lives.

Most adults with Williams syndrome are used in various settings and can perform self-care tasks. Some adults with Williams syndrome require the daily care of parents or caregivers; however, others may live with less supervision and care. Few adults with Williams syndrome live entirely independently.

Mild accelerated physical and cognitive aging has been noted.

Patient Education

Inform parents or caregivers of the Williams Syndrome Association for supporting resources and education. Williams Syndrome Associations are located in the United States and Canada. They provide valuable resources for parents and caregivers. The Williams Syndrome Association can be contacted by phone (248-244-2229) or through the Williams Syndrome Association Website.
