Summary
Daily experiences that are more unexpected, measured by surprisal, significantly increase migraine risk within 24 hours. This finding suggests a new way to predict and manage migraine attacks dynamically.
Area of Science:
- Neurology
- Data Science
- Psychology
Background:
- Identifying migraine triggers is difficult due to their numerous and variable nature.
- Unexpected daily experiences, quantified as surprisal, may predict migraine attacks by integrating various factors.
Purpose of the Study:
- To evaluate the association between surprisal and future headache attacks in individuals with migraine.
Main Methods:
- A prospective daily diary study involved 104 individuals with migraine who completed electronic entries for up to 28 days.
- Surprisal scores were calculated based on the atypicality of daily experiences, capturing behavioral, emotional, and environmental factors.
Main Results:
- Higher surprisal significantly predicted increased migraine risk within 12 and 24 hours.
- The association between surprisal and migraine onset was influenced by recent surprisal history and showed nonlinear properties.
- Individual sensitivity to surprisal varied, with those at higher risk showing weaker associations.
Conclusions:
- Surprisal provides a novel, individualized measure of trigger unpredictability linked to short-term migraine risk.
- Integrating surprisal into digital health tools could enhance personalized migraine prediction and prevention strategies.
