Rhythmicity of cluster headache

(International Headache Society) Although it is known that CH patients exhibit circadian rhythmicity of attacks, new data add a new feature with regard to the rhythmicity of attacks throughout the disease course. The time predilection of attacks seems to be non-linear, with nighttime predilection at the early phase of disease course, with a progressive increase of daytime predilection, then a return to nighttime predilection at the late phase of the period observed in the disease course.
