Intellectual abilities and adaptive behavior of children and adolescents with Kabuki syndrome: a preliminary study.
Very little is known about the intellectual abilities and adaptive behavior of individuals who have Kabuki syndrome, beyond the fact that most individuals with this syndrome have mental retardation. To fill this gap, we have completed psychological assessments of 11 children and adolescents with Kabuki syndrome. Results indicated that most of the participants functioned in the range of mild mental retardation, with both intellectual and adaptive behavior in the mildly deficient range and problem behaviors, if any, limited to mild difficulties with inattention and/or hyperactivity-impulsivity and mild problems with obsession/anxiety. At the lower extreme, one child evidenced severe mental retardation and profound adaptive behavior impairment accompanied by serious externalizing and internalizing problem behaviors. At the upper extreme, one adolescent had average intelligence and adaptive behavior, with problem behaviors well within the normal range for his chronological age. Most participants evidenced relative intellectual strengths in verbal and reasoning abilities and a relative weakness in visuospatial construction abilities. This pattern affected adaptive behavior as well, yielding a relative strength in Social Interaction and Communicative Skills and considerable weakness in Motor Skills and Personal Living Skills.
