Recently I learned of a disease called fibromuscular dysplasia. It is a non-atherosclerotic, non-inflammatory disease of blood vessels that causes abnormal growth in the artery wall. Middle aged women are most commonly affected, but men and children can also have the disorder.
The renal and carotid arteries ( in the neck ) are most commonly affected, but mesenteric, intestinal, and other areas can also have this abnormal growth in the arterial walls. Symptoms depend on what arteries are affected. If the arteries in the neck are affected, then blood flow to the brain is compromised. Fibromuscular dysplasia seems capable of producing all of the symptoms we have.
Blood flow in the vertebral and carotid arteries in the neck can also be compromised by rotated vertebrae associated with neck trauma and / or scoliosis. Additionally, some people are born with small holes in the lateral parts of the neck vertebrae - sometimes smaller on just one side. The vertebral arteries thread through these small holes, and thus blood flow to the brain can be affected by holes that are too small and by rotated vertebrae.
These various issues can predispose to little tears in the arteries - ie arterial dissection. Not good.
Has anyone had magnetic reasonance angiography on their neck arteries to see if blood flow is normal?
