Video - Angelman syndrome

Angelman syndrome (AS) is a genetic neurodevelopmental disorder characterized by problems with motor skills, speech, developmental delay, and learning disabilities. People with AS typically have happy dispositions and frequently laugh or smile, even when they are not engaged in activities that would typically elicit such reactions.

Most individuals with AS do not develop fluent speech, have sleep disturbance, and usually have seizures. People with AS typically have a normal life expectancy and have the potential to improve on some self-help skills with proper supportive care.
