Is Aicardi Syndrome genetic?
Aicardi syndrome is an extremely rare genetic disorder. Almost all people with Aicardi syndrome are females. Individuals with Aicardi syndrome have agenesis of the corpus callosum, chorioretinal lacunae and seizures.
What causes Aicardi-Goutières syndrome?
Causes of Aicardi-Goutières syndrome AGS is caused by a mutation in one or more of a small group of specific genes. The mutation leads to a buildup of small pieces of DNA in the brain, which is thought to trigger the immune response that leads to the symptoms of AGS.
Is there a cure for Aicardi syndrome?
There is no cure for Aicardi syndrome nor is there a standard course of treatment. Treatment generally involves medical management of seizures and programs to help parents and children cope with developmental delays.
What happens if the corpus callosum is removed?
How does a corpus callosotomy work? A cut corpus callosum can’t send seizure signals from one side of the brain to the other. Seizures still occur on the side of the brain where they start. After surgery, these seizures tend to be less severe because they only affect half of the brain.
What does damage to the corpus callosum cause?
Lesions of any part of the corpus callosum might lead to loss of contact between bilateral hemispheres that cause mental disorders, pseudobulbar palsy, speech and movement ataxia.
Does the corpus callosum affect memory?
These findings suggest that the corpus callosum facilitates more efficient learning and recall for both verbal and visual information, that individuals with AgCC may benefit from receiving verbal information within semantic context, and that known deficits in facial processing in individuals with AgCC may contribute to …
What is the corpus callosum responsible for?
The two hemispheres in your brain are connected by a thick bundle of nerve fibres called the corpus callosum that ensures both sides of the brain can communicate and send signals to each other.
Is agenesis of the corpus callosum a disability?
Corpus callosum agenesis or dysgenesis (CCA) can be diagnosed antenatally, either isolated or associated with other cerebral or extra-cerebral malformations….Corpus Callosum Agenesis and Intellectual Disability (ACCREM)

Do split-brain patients have two minds?
In split-brain patients, the cerebral hemispheres have been separated by severing the corpus collosum. These patients sometimes behave as if they have one mind and sometimes as if they have two.
Can split-brain patients draw?
Notice that while patients are typically unable to name stimuli presented to the left visual field, they can draw them—with their left hand—with a high degree of accuracy.
Can split-brain patients drive?
Here, using measures of information integration, we show that a brain may functionally split into two separate “driving” and “listening” systems when the listening task is unrelated to concurrent driving, but not when the two systems are related.
Why would a person have split brain surgery?
A corpus callosotomy, sometimes called split-brain surgery, may be performed in people with the most extreme and uncontrollable forms of epilepsy, when frequent seizures affect both sides of the brain.
What happens if your brain is split in two?
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.
