New Insights into Cluster Headache

Support: No funding was received for the publication of this article. C luster headache (CH) is a primary headache disorder affecting up to 0.1% of the population. 1 It is characterised by the extreme nature of the attacks, the unilateral distribution of pain and the accompanying ipsilateral autonomic symptoms and restlessness. Attacks may arise between once every other day and eight times a day during the attack periods, the bouts, and patients are highly burdened and disabled. Although the clinical features are distinct, CH may be misdiagnosed, and is suboptimally managed. In an expert interview, Nunu Lund discusses the unmet needs in the management of CH, as well as the findings of a recent study that may improve the diagnosis and management of this debilitating condition.
