The identification of comorbid disorders in migraineurs is important since it may impose therapeutic challenges and limit treatment options. Moreover, the study of comorbidity might lead to improve our knowledge about causes and consequences of migraine. Comorbid neuropathologies in migraine may involve mood disorders (depression, mania, anxiety, panic attacks), epilepsy, essential tremor, stroke, and white matter abnormalities. Particularly, a complex bidirectional relation exists between migraine and stroke, including migraine as a risk factor for cerebral ischemia, migraine caused by cerebral ischemia, migraine as a cause of stroke, migraine mimicking cerebral ischemia, migraine and cerebral ischemia sharing a common cause, and migraine associated with subclinical vascular brain lesions.

The neuroimaging of headache patients has revolutionised our understanding of the pathophysiology of primary headaches and provided unique insights into these syndromes. Modern imaging studies point, together with the clinical picture, towards a central triggering cause. ⋯ No structural changes have been found for migraine and medication overuse headache, whereas patients with chronic tension-type headache demonstrated a significant grey matter decrease in regions known to be involved in pain processing. Modern neuroimaging thus clearly suggests that most primary headache syndromes are predominantly driven from the brain, activating the trigeminovascular reflex and needing therapeutics that act on both sides: centrally and peripherally.

The notion that disorders of the cervical spine can cause headache is more than a century old, yet there is still a great deal of debate about cervicogenic headache (CEH) in terms of its underlying mechanisms, its signs and symptoms, and the most appropriate treatments for it. CEH is typically a unilateral headache that can be provoked by neck movement, awkward head positions or pressure on tender points in the neck. The headaches can last hours or days, and the pain is usually described as either dull or piercing. ⋯ Anaesthetic blocks may be necessary to confirm the diagnosis of CEH, showing that the source of pain is in the neck. Differential diagnosis is sometimes a challenge because CEH can be mistaken for other forms of unilateral headache, especially unilateral migraine without aura. Neuroimaging and kinematic analysis of neck motion may aid in diagnosing difficult CEH.

This overview of the published epidemiological evidence of migraine helps to identify the size of the public-health problem that migraine represents. It also highlights the need for further epidemiological studies in many parts of the world to gain full understanding of the scale of clinical, economic and humanistic burdens attributable to it. This paper presents some of the work on migraine undertaken by the World Health Organization (WHO) in the Global Burden of Disease study conducted in 2000 and reported in the World Health Report 2001. ⋯ Migraine causes a large proportion of the non-fatal disease-related burden worldwide. Our knowledge of headache related burden is incomplete and it is necessary to add to it epidemiological studies in many parts of the world and to combine this with measurements of disability using both DALYs and WHO's ICF Classification. The work described here has been the base for the Global Campaign against Headache disorders: "Lifting the Burden", launched in 2004 jointly by WHO, IHS (International Headache Society), WHA (World Headache Alliance) and EHF (European Headache Federation).

Lifting The Burden envisions a future world in which headache disorders are recognized everywhere as real, disabling and deserving of medical care to which all who need it have access without artificial barriers.
