Aicardi syndrome: Natural history and possible predictors of severity

Abstract

Aicardi syndrome is defined by the clinical triad of infantile spasms, agenesis of the corpus callosum, and pathognomonic chorioretinal lacunae. Almost all patients are girls with severe cognitive and physical handicaps, and epilepsy. Fourteen patients with Aicardi syndrome, seen at The Hospital for Sick Chidren, Toronto, Ontario, Canada, between 1975 and 1992, were reviewed to document the natural history of the disease and obtain life-table estimates of survival. The relationship between 28 neurologic features present in infancy and clinical outcome, as measured by mobility and cognitive function also was examined. Life-table analysis indicated that the estimated survival rate was 76% at 6 years of age and 40% at 15 years of age. Three of the 14 girls (21%) could walk or crawl and 4 (29%) had some language ability. None of the 28 neurologic features was predictive of ultimate clinical outcome. This information should be discussed with parents of children with Aicardi syndrome.
