Unusual primary headaches: Keys to an accurate diagnosis

Although some of the primary headache disorders are relatively uncommon, GPs will at times see patients with these conditions.

For many of the other headaches, the specific trigger factors (sexual activity, exertion, sleep or coughing) would suggest the correct diagnosis. The flowchart on page 43 provides a diagnostic approach to patients presenting with recurrent headaches.
