Cognitive Characteristics of Angelman Syndrome
Only a few research studies have been done to look at the cognitive characteristics of children with Angelman syndrome. This may be due to the lack of appropriate tests for assessing cognition in children with severe to profound intellectual disability.
In addition to general deficits in cognition, Angelman syndrome is associated with specific impairments in learning, attention and memory.
Mouse models of Angelman syndrome have consistently found deficits in the rates of learning acquisition.
There is minimal new research with regards to attention span, however, Sadhwani et al (2019) reported concerns for short attention span were endorsed by more than 70% of carers of individuals with AS.
