Background
Cluster headache (CH) is a primary neurovascular primary headache disorder characterized by severe strictly unilateral, typically retro-orbital or periorbital, short-lasting headaches accompanied by prominent cranial facial parasympathetic autonomic features.[1]
Pathophysiology
The underlying pathophysiology of CH is not completely understood.[2, 3] The periodicity of the attacks in CH suggests the involvement of a biological clock within the hypothalamus, with central disinhibition of the nociceptive and autonomic pathways specifically the trigeminal nociceptive pathways. The posterior hypothalamic grey matter has been identified as the key area for the basic defect in CH by neuroimaging with positron emission tomography (PET) and anatomical imaging with voxel-based morphometry.[1] Furthermore, altered habituation patterns and changes were observed within the trigeminal-facial neuronal circuitry secondary to central sensitization, in addition to dysfunction of the serotonergic raphe nuclei-hypothalamic pathways. More recently, functional hypothalamic dysfunction has recently been confirmed by abnormal metabolism based on the N-acetylaspartate neuronal marker in magnetic resonance spectroscopy.[4]
Epidemiology
Frequency
United States
The exact prevalence is unknown. Kudrow estimated 0.4% in men and 0.08% in women.[5]
International
In an extensive study of 100,000 inhabitants of the republic of San Marino, the prevalence was 0.07%.
Race
CH has been suggested to be slightly more prevalent in the African American population.
Sex
CH is more common in men, with a male-to-female ratio of 3:1.
Age
Although it is more common in the third decade of life, CH has been reported in patients as young as 1 year and as old as 79 years.
