Typical absence seizures are brief (seconds in duration) generalized epileptic seizures of abrupt onset and abrupt termination. The defining manifestations of typical absence seizures are impairment of consciousness and generalized 3 to 4 Hz spike-wave discharges. The clinico-EEG manifestations of absence seizures are syndrome-related. Childhood and juvenile absence epilepsy are the archetypal syndromes of typical absences.

In patients with primary or isolated agenesis of the corpus callosum, IQ may be normal, but impaired processing between the hemispheres can be demonstrated by detailed psychometric testing and may manifest as deficits in learning and recall. Many genetic alterations have been etiologically linked to agenesis of the corpus callosum, both as isolated developmental events as well as in the context of syndromic clusters.
