|Migraine is a neurological disorder involving episodes of head pain that are frequently throbbing, unilateral and severe. According to the International Headache Society attacks typically last 4-72 h and are often accompanied by nausea, vomiting, or sensitivity to light, sound, or movement. Approximately one-third of migraineurs have attacks that are preceded or accompanied by an aura, characterized by transient focal neurological symptoms that are most often visual but may also involve disturbances in sensory, speech and motor functioning. Migraine is best understood as a chronic disorder with episodic manifestations, progressive in some individuals. Consistently, identifying risk factors for progression has emerged asa very important public health priority. Recent studies suggested a potential role of obesity on headache outcomes.

Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
