Agenesis of the corpus callosum leads to which condition?

Agenesis of the corpus callosum leads to which condition?

• A. It is typically accompanied by a range of developmental and cognitive differences.
• B. It always causes severe motor deficits.
• C. It never affects cognitive function.
• D. It results in a disconnection syndrome with impaired interhemispheric transfer.

Answer: (D)

Agenesis of the corpus callosum disrupts communication between the brain’s two hemispheres because the major bridge that coordinates processing across sides is absent. The hallmark consequence is a disconnection syndrome with impaired interhemispheric transfer of information, meaning tasks that require coordination between the two sides can be harder and information may not be shared efficiently across hemispheres. You may see a range of developmental and cognitive differences, reflecting the brain’s adaptability, but those outcomes vary widely and aren’t uniform. Motor function isn’t consistently impaired, and cognitive function can be affected or preserved depending on the individual. The most precise description, however, is the disconnection syndrome with impaired interhemispheric transfer.
