Is Aicardi Syndrome contagious?

Aicardi Syndrome is not contagious and cannot be spread through touch, social interaction, or shared environments. It is a rare, non-infectious genetic condition caused by spontaneous mutations, meaning it is impossible for a caregiver, sibling, or friend to "catch" Aicardi Syndrome from an affected individual.

What causes Aicardi Syndrome?

Aicardi Syndrome is a rare genetic disorder that almost exclusively affects females. It is caused by a new (de novo) mutation on the X chromosome. Because it is a genetic event, it is not triggered by external pathogens like viruses or bacteria, nor is it caused by anything a parent did or did not do during pregnancy. The condition is characterized by the partial or complete absence of the corpus callosum, the structure connecting the two hemispheres of the brain.

Why is there confusion regarding contagion?

Because Aicardi Syndrome involves complex neurological symptoms, such as infantile spasms and developmental delays, observers sometimes mistakenly assume the condition is an infectious disease. This stigma often stems from a lack of public awareness regarding rare genetic disorders. It is important to emphasize that there is absolutely no risk to others when interacting with someone who has Aicardi Syndrome. Living with, hugging, or caring for a person with this condition poses zero risk of transmission.

Are there environmental triggers for Aicardi Syndrome?

While the root cause is genetic, the manifestation of Aicardi Syndrome can be influenced by various factors that are often confused with triggers for infection. Families should be aware of the following facts regarding the condition:

• Aicardi Syndrome is not caused by environmental toxins or infectious agents.


• Seizure activity in Aicardi Syndrome may sometimes increase during a fever, which is a common response to illness, but the illness itself does not cause the syndrome.


• There is no evidence that vaccination or dietary choices influence the development of Aicardi Syndrome.
