Agenesis of the Corpus Callosum


Agenesis of the Corpus Callosum (ACC) is a birth defect in which the structure that connects the two hemispheres of the brain (Corpus Callosum) is partially or completely absent.

'Agenesis' means absent. The Corpus Callosum is the largest fibre tract in the central nervous system.

ACC is a spectrum of disability ranging from some pupils who are mildly affected to pupils who have severe special needs.
