Cluster headache (CH) is commonly regarded as one of the most disabling headache conditions, and referred to as one of the most painful conditions known to humankind. Although there has been some research indicating the severe impact of CH, there is little comprehensive evidence of its impact on quality of life, disability, mood, and cognitive function in both its episodic (ECH) and chronic (CCH) variants.
