An Acephalgic migraine( also known as a 'Silent migraine') is a kind of migraine without the head pain. Acephalgic is Latin for "without head pain"). Most kinds of migraines start before a person is 30-years-old but this kind of migraine usually starts sometime during middle-age, which is after 40-years-old, and becomes more common as a person gets older. Unlike other migraines, males have Acephalgic migraines more often then women do.
