Agenesis of the Corpus Callosum
Background
Agenesis of the Corpus Callosum (ACC) is a rare neurological condition. The Corpus Callosum is a bridge of white matter joining the two cerebral hemispheres of the brain. It forms during the course of brain development. The frequency with which it fails to form is normally not known as its total or partial absence can only be demonstrated with brain imaging procedures and these will usually only be performed if individuals have neurological abnormalities. Hence there may well be many asymptomatic individuals with partial or complete callosal agenesis.
