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
Headache type is not stable over time.[2]
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
- Criteria
Diagnostic criteria developed by the International Headache Society are:[3]
Migraine without aura:
A. At least 5 attacks fulfilling criteria B-D
B. Headache attacks lasting 4-72 hours (untreated or unsuccessfully treated)
C. Headache has at least two of the following characteristics:
- unilateral location
- pulsating quality
- moderate or severe pain intensity
- aggravation by or causing avoidance of routine physical activity (eg, walking or climbing stairs)
D. During headache at least one of the following:
- nausea and/or vomiting
- photophobia and phonophobia
E. Not attributed to another disorder
Tension headache
Cluster headache
- Criteria
Diagnostic criteria developed by the International Headache Society are:[4]
A. At least 5 attacks fulfilling criteria B-D
B. Severe or very severe unilateral orbital, supraorbital and/or temporal pain lasting 15-180 minutes if untreated1
C. Headache is accompanied by at least one of the following:
- ipsilateral conjunctival injection and/or lacrimation
- ipsilateral nasal congestion and/or rhinorrhoea
- ipsilateral eyelid oedema
- ipsilateral forehead and facial sweating
- ipsilateral miosis and/or ptosis
- a sense of restlessness or agitation
D. Attacks have a frequency from one every other day to 8 per day
E. Not attributed to another disorder
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.[5]
Diagnosis
X-ray computed tomography (CT Scan) should be considered if one of the following is present:[6]
- 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%[6]
- New-onset or change in chronic headaches. Prevalence of significant pathology is 32%.[6] This compares to a prevalence of significant pathology of 1% for patients with chronic headaches referred to a neurologist.[7] Presumably the prevalence would be lower in primary care.
- Patients with human immunodeficiency virus. This is based on a clinical practice guideline.[8]
Treatment
Prochlorperazine is better than promethazine in relieving nonspecific, benign headaches according to a randomized controlled trial.[9]
After relief has been achieved, recurrence may be similarly affected by oral sumatriptan and oral naproxen.[10]
Migraine headache
Tension headache
Prognosis
Most chronic headaches are tension-type headache, although migraine may coexist.[11] Almost half have medication overuse.[11]
