If your doctor sees a problem with the corpus callosum, they may refer you for several tests, if these have not already been done. How serious is the agenesis of the corpus callosum in my fetus? Therefore, the symptoms of agenesis of the corpus callosum can become more evident as a child grows into adolescence and young adulthood. A child with agenesis of the corpus callosum may keep up with his or her peers until this age however, they may begin to fall behind in schoolwork and social functioning. At this phase in their development, children with a normally formed corpus callosum make progress in their abstract reasoning and problem solving, and their social skills mature. Throughout childhood, the nerve fibers of the corpus callosum continue to grow and become more efficient, even through the teenage years.
Whether a child has these symptoms or difficulties depends partly on whether other brain development problems are detected on MRI and whether there is a problem with the child’s chromosomes. Other children may have severe handicaps such as cerebral palsy, severe intellectual or learning disabilities, autism or seizures. Some children with agenesis of the corpus callosum have only mild learning difficulties. What is the outcome with agenesis of the corpus callosum? In most cases, it is not possible to know what specifically caused the disruption. This disruption may be related to chromosome errors, genetic factors, prenatal infections, or other factors related to the prenatal environment. It may occur as an isolated brain problem, in combination with other brain abnormalities, such as ventriculomegaly, or in combination with problems with other organs, such as a congenital heart defect.Īgenesis of the corpus callosum is caused by disruption of the development of the fetal brain. The corpus callosum coordinates signals from different parts of the brain and helps us in our thinking.Īgenesis of the corpus callosum is a birth defect in which this structure in the brain is either partially or completely missing. One of it’s functions is to connect the right and left sides of the brain to allow for communication between the two sides, or hemispheres. The corpus callosum is a collection of many millions of nerve fibers in the middle of the brain.
