The Arnold-Chiari malformation is a congenital defect characterized because the cerebellum (the part of the brain that controls balance) projects and comes to occupy part of the space for the spinal cord. In many cases, it occurs because of not having enough space. Although sometimes might not have any symptoms and goes unnoticed throughout life, Chiari malformation, can obstruct proper circulation of the cerebrospinal fluid, which makes communication between the brain and the rest of the body. Consequently, Chiari disease causes significant motor difficulties. Currently, the only treatment to correct their effects and stop its evolution is the cranial surgery.
