Warning Signs Of Chiari Malformation

Chiari malformation is an abnormality of structure that affects the relationship between the brain and skull. An affected individual's skull may be misshapen or smaller than normal, resulting in the compression of the brain tissues at the base of the skull. This pressure and compression cause the patient's brain tissues to protrude into their spinal canal. The base of the brain affected by Chiari malformation is referred to as the cerebellum. The signals from the brain to the body can become obstructed when the cerebellum is pushed down into the spinal canal. Most cases of Chiari malformation are congenital and result from genetic mutations, lack of nutrients and vitamins during pregnancy, infection during pregnancy, or chemical exposure during pregnancy. However, an adult may develop Chiari malformation when infection or an accident results in the drainage of spinal fluid.
