The following is a list that many people who have been diagnosed with ACM have reported to their doctors in searching for answers.

Obviously, every individual experiences ACM differently and it is possible to present with very few or all of the symptoms on this list. This list comprises the most common complaints Chiari patients share with their providers, but other symptoms may exist.


In addition, many of the symptoms cross over to other disorders. This is why we are often misdiagnosed with Fibromyalgia, Chronic Fatigue Syndrome, Lupus, and other “Mystery” diagnoses.


The only way to tell for sure if A.C.M. Is present is by taking and MRI of the brain and or tracking the cerebral spinal flow of the patient.
