Migraine is a neurological headache disorder with sensory sensitivity, nausea, and sometimes aura. Triggers vary by person.

Serotonin, free fatty acids, and blood sugar

[edit]

Blood sugar dips, estrogen swings, serotonin shifts, and low CO2/magnesium themes appear in the bioenergetic frame. Regular meals, sleep, and thyroid evaluation help some people. Acute severe headache with neurological signs needs emergency care.

Serotonin was already tied to migraine, carcinoid syndrome, dumping syndrome, vascular disease, and hypertension by the mid-1980s, which drove a search for serotonin antagonists; the widest clinical use of those antagonists has been migraine prevention.[1]

In 10 migrainous patients, total plasma free fatty acids rose and platelet serotonin fell during attacks; among individual fatty acids, linoleic acid rose most from the quiet baseline before an attack to headache. In 10 non-migrainous controls, ingesting 20 g linoleic acid produced a significant fall in platelet serotonin, and linoleic acid also released platelet serotonin in vitro. Linoleic acid acts as both a serotonin-releasing factor and a source of vasodilating prostaglandin E1 during the attack.[2] Stress liberates free fatty acids from triglycerides; omega-6 fats raise plasma serotonin; keeping blood sugar up limits that free-fatty-acid rise, which is one reason carbohydrate foods such as orange juice appear in practical migraine management alongside serotonin blockers such as cyproheptadine.

Increasingly, intestinal serotonin is being recognized as a factor in osteoporosis, migraine, irritable bowel syndrome, appendicitis, and cancer. From ancient times until about 100 years ago, the bowel had a very important place in medical practice, with purgatives and enemas being recommended for headaches, persistent coughs, seizures, and many chronic diseases.

Hypothyroid people often have very high serotonin; T3 lowers its production and retention, and serotonin, which promotes inflammation and acts on blood vessels, is a major factor in migraine.[4] In migraine, visual symptoms probably come from constricted arterioles and the pain from engorged veins; progesterone activates MAO-A and has other antiserotonin effects on vessels and nerves.[5]

A very large amount of sugar will usually relieve a migraine; about a quart of ice cream, or milkshakes with some fat and protein, make the sugar easier to take, and caffeine sometimes makes aspirin and sugar more effective.[6] Cyclic depression or migraine at a young age can be one sign of a progesterone or thyroid deficiency that later shows up as breast disease or pregnancy problems.[7]

Cyproheptadine

[edit]

In 12 adults with frequent migraine who had failed or stopped lomerizine, valproic acid, and topiramate, cyproheptadine hydrochloride at 4 mg at bedtime (raised to 8 mg/day when sleepiness allowed) cut attack frequency within 7 to 10 days and kept it much lower over three months.[8] See Cyproheptadine.

Spinal cord mitochondrial dysfunction and hypersensitivity

[edit]

In a nitroglycerin-induced migraine model, mitochondrial dysfunction in the spinal cord drove peripheral hypersensitivity, with impaired mitochondrial dynamics raising pro-inflammatory cytokines and reactive oxygen species; hyperbaric oxygen therapy improved both mitochondrial function and the resulting hypersensitivity, depression, and anxiety-like behavior. Migraine has a metabolic as well as a vascular origin: a shift from oxidative toward anaerobic metabolism raises lactate, serotonin, and nitric oxide, the substances most directly implicated in migraine's vasodilatory and pain-sensitizing effects.[9]

Periodic migraines and nearsightedness beginning around age nine or ten, with some nearsighted classmates also having migraines, was an early personal observation behind later interest in the migraine/vision/thyroid connection.[10]

Riboflavin

[edit]

In a 3-month randomized placebo-controlled trial (55 patients), 400 mg/day riboflavin (vitamin B2) cut migraine attack frequency and headache days significantly more than placebo; 59% of the riboflavin group improved by at least 50% versus 15% on placebo (number needed to treat: 2.3).[11]

Prolactin

[edit]

Serum prolactin runs higher in migraine patients than in healthy controls, and prolactin-secreting pituitary tumors correlate with more frequent headache in otherwise healthy people and more frequent attacks in migraine patients, per a systematic review of 19 clinical studies.[12]

Vitamin E lowers prolactin as an estrogen receptor antagonist and aromatase inhibitor, reducing the estrogen stimulus to the pituitary's prolactin-producing cells. In hemodialysis patients, eight weeks of vitamin E significantly lowered serum prolactin without affecting FSH, LH, or free testosterone.[13] See Prolactin for the fuller estrogen/serotonin/prolactin picture.
