Alternating hemiplegia of childhood: a study of neuropsychological functioning.
Alternating hemiplegia of childhood (AHC) is a rare chronic neurological disorder characterized by alternating transient attacks of hemiplegia. Evidence from recent studies suggests the disorder is characterized by tonic fits, dystonic posturing, and ocular motor abnormalities. Although widely observed, deficits in cognitive functioning are among one of the least described features of AHC. Most studies describe global deficits, however, no study has provided a comprehensive neuropsychological assessment of a child with AHC. This study presents neuropsychological findings from a comprehensive assessment of a single child with AHC. Results showed significant deficits in intellectual, academic, memory, attention, and executive functioning. Additional deficits in language, psychomotor abilities, and psychosocial functioning were noted. Preliminary longitudinal data are also offered to examine the progressive nature of this disorder. Cognitive strengths and weaknesses are discussed at length as well as recommendations for the classroom and future research.
