A 23-Year Review of Communication Development in an Individual With Agenesis of the Corpus Callosum

Twenty-three years of observation and testing of the communication skills of a male participant with agenesis of the corpus callosum (ACC) and normal IQ revealed initial weakness in content and form of language. While his general ability to communicate improved over time, difficulties with fluent speech in conversations and pragmatic language skills persisted into young adulthood. With intensive intervention, communication and academic skills developed by late adolescence, which allowed the participant to complete a regular high school program. Discussion includes similarities and differences between this longitudinal case study and other reports of individuals with ACC with respect to communication skills. A clinical intervention approach based on collaboration between client, school, and the client's family is described.
