Chiari malformations (CMs) (Keire Malformations or kiare malformation) includes a complex group of disorders characterized by herniation of the cerebellum, the part of the brain that controls balance.
When the indented bony space at the lower rear of the skull is smaller than normal, the cerebellum and brainstem can be pushed downward.The resulting pressure on the cerebellum can block the flow of cerebrospinal fluid (the liquid that surrounds and protects the brain and spinal cord) and can cause a range of symptoms including dizziness, muscle weakness, numbness, vision problems, headache, and problems with balance and coordination. There are three main types of CM. CM1, the simplest and most prevalent form.
