The trigeminal autonomic cephalalgias (TACs) are highly disabling primary headache disorders. There are several issues that remain unresolved in the understanding of the pathophysiology of the TACs, although activation of the trigeminal–autonomic reflex and ipsilateral hypothalamic activation both play a central role. The discovery of the central role of the hypothalamus led to its use as a therapeutic target. After the good results obtained with hypothalamic stimulation, other peripheral neuromodulation targets were tried in the management of refractory cluster headache (CH) and other TACs.Read More →

Cluster headache is a relatively rare headache disorder, typically characterized by multiple daily, short-lasting attacks of excruciating, unilateral (peri-)orbital or temporal pain associated with autonomic symptoms and restlessness. To better understand the pathophysiology of cluster headache, we used RNA sequencing to identify differentially expressed genes and pathways in whole blood of patients with episodic (n = 19) or chronic (n = 20) cluster headache in comparison with headache-free controls (n = 20).Read More →

Cluster headache is characterized by recurrent unilateral headache attacks of severe intensity. One of the main features in a majority of patients is a striking rhythmicity of attacks. The CLOCK (Circadian Locomotor Output Cycles Kaput) gene encodes a transcription factor that serves as a basic driving force for circadian rhythm in humans and is therefore particularly interesting as a candidate gene for cluster headache.Read More →

Most of the barriers preventing an appropriate care of CH sufferers may be overcome with a little organisational and cultural effort. The European Headache Alliance and the European Headache Federation have launched the Cluster Headache Day with the intention to solicit the Members of the European Parliaments’ help in promoting actions for improving the quality of life of CH patients.Read More →

Cluster headache (CH) comprises the most frequent trigeminal-autonomic headache syndrome and has a mean prevalence of 0,1% [1]. The designation highlights its typical pattern, in which each attack (a single episode of headache) occurs in clusters or bouts of variable duration, with a circadian and circannual rhythmicity [1, 2].Read More →

Despite being an excruciating headache, little is known about the burden of cluster headache (CH) regarding its various subtypes. In a multicentre, prospective study, patients with chronic CH (n¼27), with episodic CH in the active (n¼26) and outside the active period (n¼22), migraine patients (n¼24) and healthy controls (n¼31) were includedRead More →
