Aicardi syndrome is a rare disorder passed down through families (inherited) in which the structure that connects the two sides of the brain (called the corpus callosum) is partly or completely missing.
Causes, incidence, and risk factors
The cause of Aicardi syndrome is unknown at this time. In some cases, experts believe it may be a result of a gene defect on the X chromosome.
The disorder affects only girls.
Symptoms usually start when the child is between ages 3 and 5 months. The condition causes jerking (infantile spasms), a type of childhood seizure.
Aicardi syndrome may occur with other brain defects.
The outlook depends on how severe the symptoms are and what other health conditions are present.
Nearly all children with this syndrome have severe learning difficulties and remain completely dependent on others. However, a few have some language abilities and some can walk on their own or with support. Vision varies from normal to blind.
Complications depend on the severity of symptoms.
Calling your health care provider
Call your health care provider if your child has symptoms of Aicardi syndrome. Seek emergency care if the infant is having spasms or a seizure.
