Patients Ratings of Migraine Severity

Migraine subtype, frequency of migraine, and migraine-related disability were statistically significant predictors of patient ratings of migraine severity, according to a new study that utilized the Global Assessment of Migraine Severity (GAMS) tool to access migraine severity in busy clinical settings. The cohort study included 263 adult migraine patients (mean age 42.5 years) consecutively enrolled in the Neurological Disease and Depression Study (NEEDs). Researchers obtained a range of clinical and patient-reported measures and migraine-related disability. Among the findings:

  • 209 (79.4%) patients were female; 177 (67.4%) participants reported “moderately severe” to “extremely severe” migraine on the GAMS, and 100 (31.6%) patients had chronic migraine.
  • Patients’ report of severity on the GAMS was strongly correlated with patients’ ratings of MIDAS global severity question, overall MIDAS score, migraine type, PHQ-9 score, and frequency of migraine attacks.
  • Overall, migraine subtype, frequency of migraine, employment status, depression, and migraine-related disability were statistically significant predictors of patient ratings of migraine severity.
