How common is headache- What is the prevalence of headaches
Having had any type of headache is a near universal experience, with a lifetime prevalence of 90% and a 1-year prevalence of over 50% (migraine 12% and tension type 38%).
Migraine is the third most prevalent disorder and seventh highest specific cause of disability worldwide.
Approximately 90% of headaches in patients with a normal neurologic examination are primary (such as migraine, tension type, and cluster).
The remaining 10% are due to numerous secondary causes.
There are over 300 different types and causes of headaches.
Since there are only so many ways your head can hurt, there is overlap between the symptoms of primary and secondary headaches, although different headache types may have signature features.
