Headache is defined as "the symptom of pain in the cranial region. It may be an isolated benign occurrence or manifestation of a wide variety of headache disorders."[1]
Classification
Primary headaches
Primary headaches are defined as "conditions in which the primary symptom is headache and the headache cannot be attributed to any known causes."[1]
Migraine headache
Tension headache
Secondary headache
Secondary headaches are defined as "conditions with headache symptom that can be attributed to a variety of causes including brain vascular disorders; wounds and injuries; infection; drug use or its withdrawal."[1]
The role of overuse of medications for treating migraine (triptans, analgesics, ergots) and their withdrawal as a cause of headache is controversial.[2]
Diagnosis
X-ray computed tomography (CT Scan) should be considered if one of the following is present:[3]
- cluster-type headache
- abnormal findings on neurologic examination
- undefined headache (ie, not cluster, migraine, or tension-type)
- headache with aura
- headache aggravated by exertion or a valsalva-like maneuver
- headache with vomiting
CT scan should also be considered in the following settings:
- Acute thunderclap headache. Prevalence of significant pathology is 40%[3]
- New-onset or change in chronic headaches. Prevalence of significant pathology is 32%.[3] This compares to a prevalence of significant pathology of 1% for patients with chronic headaches referred to a neurologist.[4] Presumably the prevalence would be lower in primary care.
- Patients with human immunodeficiency virus. This is based on a clinical practice guideline.[5]
