Headache: is it worse when it’s a surprise?

Takeaway

  • The impact of numerous unexpected headache triggers on existing and future headache in individuals with episodic migraine (EM) can be conceptualized using information theoretic methods.

Why this matters

  • There are limited data characterizing the effect of unanticipated headache triggers on headache outcome; this model provides a foundation for future studies looking to validate these associations.
