Do You Know the Anatomy of Migraine is Now Known?

Part 2 of a 3-part series on migraines was published today and if you really want to understand migraines, I recommend you read part 1 first and then read part 2, which is a bit more comprehensive and scientific.

I copy paste here the beginning to capture your interest but please read the rest on the page where it is posted:

What is the anatomy of a migraine? Do migraines have an anatomy, a location map, in the same way heart disease does? Sure, migraine happens in the brain and we feel the pain in our head if there is pain – not all migraines come with pain, but does the pain guide us to a causative anatomy of the migraine the same way a heart attack does to the heart? No, it does not; at least not in the same way a blocked artery points to the cause of heart attack. The symptoms of migraines correspond to no specific regions of the brain, except in the case of the aura migraine, which points at the visual cortex. Only about 15% of those with migraines have auras. For 85% of the cases, we do not have the anatomical location of the migraine understood. Most science seems to consider aura and non-aura migraine different in nature and cause. Are they? Maybe not.

Most migraines are not connected to the symptoms we feel (nausea, dizziness, IBS, RLS, anxiety, nausea, vomit, etc.) and because of the variety of symptoms, there is nothing to guide us, such as a scan of the arteries for heart or a stroke. Another contributing factor is that there are no pain sensing nerves in the brain. All pain is felt by the trigeminal neuron receptors that are located on the meninges of the brain. That is, the pain we feel as migraineurs is disconnected from the actual location that causes migraines. To find the anatomy of a migraine, we need to go beyond the symptoms and the pain of the disease, beyond the visible disturbance of the eye in the aura, to the underlying cause for these symptoms.

For much of recent history, migraine research has revolved around two discrete theories of migraines: vascular and non-vascular mental illness. The two schools of thought were merged into what is now called neurovascular disease. But the latest findings suggest that there is more to migraines than neurovascular disease.

Migraine as Vascular Disease

For much of the 20th century, migraine was considered to be a vascular disease. This meant that migraine pain was caused by cranial blood vessel dilation or constriction. Still today we can see many over-the-counter migraine drugs that constrict blood vessels with caffeine in order to constrict the vascular structure of the brain (and the heart and the rest of our body). Alternatively, many doctors still prescribe beta blockers that reduce blood pressure and loosen arteries for easier blood flow and reduced constriction. If migraine is a disease of vascular nature, what causes the cranial vasodilation changes, particularly if these changes do not affect the heart or other parts of the body? This is the first clue that migraines are something more than just vascular in nature.

Migraine as Non-Vascular Mental Illness

The second prominent theory in migraine research attributes migraine pain to alterations… more

Questions and comments are welcome! This article contains lots of scientific evidence and is written on a bit more scientific language. Please feel free to ask if something confuses you!

About Be Healthy

Angela A Stanton, PhD, is a Neuroeconomist who evaluates changes in behavior, chronic pain, decision-making, as a result of hormonal variations in the brain. She lives in Southern California. Her current research is focused on migraine cause, prevention and treatment without the use of medicines. As a migraineur, her discovery was helped by experimenting on herself. She found the cause of migraine to be at the ionic level, associated with disruption of the electrolyte homeostasis, resulting from genetic mutations of insulin and glucose transporters, and voltage gated sodium and calcium channel mutations. Such mutations cause major shifts in a migraine brain, unlike that of a non-migraine brain. A non-migraineur can handle electrolyte changes on autopilot. A migraineur must always be on manual guard for such changes to maintain electrolyte homeostasis. The book Fighting The Migraine Epidemic: How To Treat and Prevent Migraines Without Medicines - An Insider's View explains why we have migraines, how to prevent them and how to stay migraine (and medicine) free for life. As a result of the success of the first edition of her book and new research and findings, she is now finishing the 2nd edition. The 2nd edition is the “holy grail” of migraines, incorporating all there is to know at the moment and also some hypotheses. It includes an academic research section with suggestions for further research. The book is full of citations to authenticate the statements she makes to be followed up by those interested and to spark further research interest. While working on the 2nd edition of the book she also published academic articles: "Migraine Cause and Treatment" Mental Health in family Medicine, November 23, 2015, open access "Functional Prodrome in Migraines" Journal of Neurological Disorders, January 22, 2016, open access "Are Statistics Misleading Sodium Reduction Benefits?", Journal of Medical Diagnostic Method, February 3, 2016, open access “A Comment on Severe Headache or Migraine History Is Inversely Correlated With Dietary Sodium Intake: NHANES 1999-2004” Angela A Stanton PhD, 19 July 2016 DOI: 10.1111/head.12861 not open access, subscription is required to read it. Dr. Stanton received her BSc at UCLA in Mathematics, MBA at UCR, MS in Management Science and Engineering at Stanford University, PhD in NeuroEconomics at Claremont Graduate University, and fMRI certification at Harvard University Medical School at the Martinos Center for Neuroimaging for experimenting with neurotransmitters on human volunteers.
