- Headache affects 95% of people in their lifetime
- Headache affects 75% of people in any one year
- One in 10 people have migraine
- One in 30 people have headache more often than not, for 6 months or more
- At least 90% of patients seen in a neurology outpatient clinic with headache will have migraine, tension type headache, or a chronic daily headache syndrome
- Sinister causes of headache are rare, perhaps 0.1% of all headaches in primary care
切記:在急診看頭痛病人時,不能用好發率來思考,要反過來,應該優先排除那 0.1% 的 sinister causes,尤其是致命的 SAH!
