Cluster headache (CH) is a rare but severe headache disorder characterised by repeated unilateral head pain attacks accompanied by ipsilateral autonomic features. In episodic CH, there are periods of headache attacks with pain-free intervals of weeks, months or years in between. ⋯ In this article, we give a review of the chronic forms of CH and focus on demographics, clinical manifestations, social habits, predictive factors, head injury, genetics, neuroimaging and therapy. It is remarkable that little is known about risk factors that make CH chronic.

This study aimed to gain insight into the management of migraine and chronic daily headache (CDH) from the patients' perspective. This article outlines the patients' perceptions of migraine and chronic daily headache. Thirteen semi-structured interviews were carried out with patients suffering from IHS migraine. ⋯ The theme 'headaches' was sub-divided into 'their pain and symptoms', 'differentiating between their headaches' and 'perceptions of headaches as barriers and facilitators to management'. The patients' perceptions of migraine and CDH were sometimes conflicting and influenced the patients' management behaviours. The qualitative methodology may help to inform doctors, other healthcare professionals and headache researchers about the patients' perspective and possibly develop future headache research, care and education.

The objective is to identify the pathogenesis of each autonomic manifestation in cluster headache (CH). Through a deductive statistics method (factor analysis) we analysed the type of autonomic symptoms reported by 157 CH patients. Three principal components were identified in the analysis: parasympathetic activation (lacrimation, conjunctival injection and rhinorrhoea), sympathetic defect (miosis and ptosis) and parasympathetic mediated effect (nasal congestion, eyelid oedema and forehead sweating). This work suggests that there are three different mechanisms underlying autonomic manifestations in CH.
