Which condition is characterized by agenesis of the corpus callosum?

• A. Corpus callosum agenesis
• B. Hydrocephalus
• C. Spina bifida
• D. Anencephaly

Answer: (A)

Agenesis of the corpus callosum is a brain development condition where the corpus callosum, the large bundle of nerve fibers that connects the two cerebral hemispheres, fails to form or is only partially formed. This missing bridge can disrupt how the left and right sides of the brain share information, leading to a range of outcomes from subtle to more noticeable cognitive, language, and motor coordination differences, and in some cases seizures. Some people function well with few or no symptoms, while others may have developmental delays or learning challenges. The other options describe different conditions: hydrocephalus involves excess cerebrospinal fluid and enlarged ventricles; spina bifida is a neural tube defect affecting the spine; anencephaly is a severe condition where much of the brain and skull do not develop.
