Cluster headache - Reflexions

Cluster headache

A primary headache causing facial and head pain always on the same side. The pain is unbearable and accompanied by ipsilateral autonomic signs: red eye, lacrimation, edema of the eyelid, nasal congestion, as well as restlessness. The attacks can occur several times per day, often during the night. They last between 15 and 180 minutes (average : 45 minutes). In the episodic form of the disorder (90% of cases), there is seasonal rhythm with bouts of daily attacks lasting several weeks alternating with periods of remission without attacks lasting several months. 10% of affected subjects have or develop the chronic form where there are no periods of remission for years. In contrast to migraine which is more frequent in women, cluster headache affects mostly men.
