Adaptive behaviour in Angelman syndrome: its profile and relationship to age.

Doctors tested 25 people who have Angelman syndrome. They used the Vineland Adaptive Behavior Scales to see how each person scored in daily living, social, and communication skills.

Every person had a gene test that proved the Angelman diagnosis.

No one in the group reached a 3-year level in any skill area. Personal care skills, like feeding or dressing, were the strongest area. Social and communication skills were the weakest.

Mertz et al. (2014) looked deeper and split the same syndrome into genetic types. They found people with the big deletion had even lower scores than the group in Chou et al. (2010).

Scior et al. (2023) talked to caregivers and heard rich stories of how these people do communicate. Their work adds detail to the weak communication picture first shown in Chou et al. (2010).

Duis (2022) wrote a big-picture review that folds in the 2010 data. She warns that new gene therapies are coming, so we need clear baseline profiles like this one to measure change.

If you write goals for someone with Angelman, keep them under the 3-year ceiling. Focus first on practical self-care, then add simple social or communication targets. Use the profile as a quick reality check when parents hope for higher skills.
