Paediatric migraine is a chronic neurological disorder with a strong genetic component, characterised by episodic, moderate-to-severe attacks of headache, nausea, vomiting, and sensitivity to light and noise.
Functional impairment during attacks is common, with normal function returning between episodes.
Onset can occur at any time during childhood and adolescence.
According to the International Headache Society (IHS), migraine episodes last 2-72 hours, are unilateral or bilateral, have a gradual onset (15-30 minutes), pulsating quality, and moderate-to-severe intensity aggravated by routine physical activity.
