(173) Information Theory and Headache Triggers

Approximately 90% of individuals with headache believe there is at least one trigger, or causal factor, of their headache attacks. The list of headache triggers is extensive, but little is known about how individuals develop such beliefs. The aim of this secondary analysis was to evaluate the degree of information, measured using Shannon entropy, that headache triggers contain and to examine the relationship between joint entropy (i.e., triggers and headache activity) and trigger beliefs. We hypothesized that as information about a headache trigger increased (i.e., an individual was exposed to more states of the trigger), the strength of belief about the trigger also would increase.
