Angelman Syndrome Research and Treatment Center

Angelman Syndrome (AS) is a neuro-genetic disorder, affecting approximately 1 in 15,000 individuals in the general population. AS is diagnosed through a DNA (blood) test. The exact cause of AS has yet to be discovered. Common characteristics of AS include developmental delay, speech impairment and movement disorders. Cincinnati Children’s Angelman Syndrome Research and Treatment Center serves males and females of all ages affected by AS.

Since a cure for AS has not been developed, current treatment focuses on the management of symptoms, typically using an interdisciplinary approach to provide an individualized level of treatment for each patient. The Angelman Syndrome Research and Treatment Center provides educational materials, medication management for behavioral symptoms, behavioral and cognitive assessments, and behavioral interventions. Referrals for other services including speech therapy, occupational therapy, and special education consultation, can be made within Cincinnati Children's.
