Using Behavioral Approaches to Assess Memory, Imitation and Motor Performance in Children with Angelman Syndrome: Results of a Pilot Study

Abstract

ABSTRACT Purpose: This study was designed to assess memory, imitation of motor actions and motor performance by 12 children (age range 40–151 months) with Angelman syndrome (AS), a rare neurogenetic disorder associated with learning and memory impairments. Methods: Children’s functioning was assessed at several time points over a 3-month period. Results: Memory and motor performance tests had acceptable test-retest and inter-rater reliability whereas the motor imitation test did not. Children were able to recall action sequences after a 24-h delay. Memory and motor performance scores were correlated with children’s chronological age and raw scores on subdomains of the Vineland-II. Conclusions: These behavioral tests require further development and evaluation but may show promise to accompany standardized assessments that are currently in use with children with AS.
