Migraine – Causes

February 22, 2022


“The causes of Migraines are very difficult to tell. We don’t fully understand them. Part of that is because enough research doesn’t go into migraine and headaches in general – I can’t just say migraines. We used to believe it was all vascular, meaning too much blood was rushing up to the head. We now realize it’s only a tiny portion of it and it’s mainly a chemical or neurotransmitter. A chemical P (or substance P) is released into the head and that basically turns on the nerves and causes more pain. There’s a small portion of blood flow issues, but we don’t fully understand all the causes related to it. We also don’t fully understand everything that turns off in a migraine.
