EP 89. Experimental provocation of “ice-cream headache” by ice cubes and ice water

Ice-cream headache, now called "Headache attributed to ingestion or inhalation of cold stimulus" (HICS), is characterized by a short-lasting frontal or temporal pain induced in susceptible people by passage of cold material over the palate and/or posterior pharyngeal wall (Headache Classification Committee, 2013). A number of studies have investigated HICS by different experimental approaches. These studies either used ice cubes, ice water or ice cream. In the present study two protocols (ice cubes and ice water) were tested towards their efficiency of HICS provocation and whether clinical features differ in those protocols.
