Chiari Malformation
Chiari Malformation Causes
A very small or deformed section of the skull that contains the cerebellum causes chiari malformation. This puts pressure on, and crowds the brain interfering with the normal flow of cerebrospinal fluid that protects the brain and spinal cord. Studies show evidence that the condition is hereditary. However, research is still on its early stage.
Chiari Malformation Definition
Chiari malformation is the displacement of brain tissue into the spinal canal.
Chiari Malformation Diagnosis
Since most symptoms of the condition may be associated with other disorders, the patient is referred to specialists to undergo thorough and appropriate tests. The patient's medical history is recorded and a complete physical examination is conducted. Doctors assess the patient's symptoms by asking the patient to describe them and, may conduct a magnetic resonance imaging scan of the skull if the cause is not apparent. MRI is the definitive diagnostic tool for the condition.
Chiari Malformation Symptoms and Signs
Signs and symptoms depend on the type and severity of condition and may occur only in adulthood. However, they usually occur during infancy. affected persons may experience headaches. Severe types of the condition can also include myelomeningocele. Affected individuals with a very severe form of Chiari malformation, usually die in infancy. In such cases, the brain has no normal development.
Chiari Malformation Treatment
The condition is treated depending on the severity and symptoms of the condition. If there are no symptoms, the doctor may only regularly examine the patient's condition. For primary symptoms such as headaches, pain medications may be prescribed. Patients with symptomatic Chiari malformation undergo surgery to relieve pressure on the cerebellum and the spinal cord as well as to restore the normal flow of spinal fluid.
