Evaluation of migraine burden across episodic and chronic migraine frequencies

Key messages

  • Migraine is a chronic neurologic disease characterized by headache pain with nausea and sensory sensitivity in various combinations.
  • There was a strong linear relationship between monthly headache day frequency and measures of migraine burden and healthcare resource utilization, showing increases in all measures among high-frequency episodic migraine (HFEM) respondents compared to low-frequency chronic migraine (LFCM).
  • Results showed substantial overlap in levels of burden, anxiety, depression and healthcare utilization among HFEM and LFCM.
  • Treatment needs of HFEM and LFCM may be similar.
  • The 15-monthly headache day threshold used for the diagnosis of chronic migraine may merit reconsideration.
