Abstract

Patients with migraine have a platelet hyper-aggregability. As this alteration could be the consequence of an abnormal lipid composition of platelet membranes, we studied the phospholipid specimens and the cholesterol/phospholipid ratio in platelets of seven patients suffering from migraine. The holesterol/phospholipid ratio was 0.7 ± 0.1 (normal 0.6 ± 0.1, molar ratio). The proportion of five main platelet phospholipids components including phosphatidylcholine, phosphatidylethanolamine, sphingomyelin, phosphatidylserine, and phosphatidylinositol, were also normal. These data suggest that platelet hyperactivity in patients with migraine is not due to an altered lipid content of these cells.
