Detailed Description:
Chronic post-traumatic headaches develop in about one third of soliders who have had head trauma caused by a blast. A wide variety of pain medicines, including rizatriptan, are used to treat these headaches in clinical practice. However, the effectiveness has not been established by clinical research studies.

Ages Eligible for Study:   18 Years to 49 Years   (Adult)

  18. Migraine Disability Assessment Score (MIDAS) greater than 10 or Headache Impact Test-6 (HIT6) score greater than 60.

Exclusion Criteria:

  1. Patients with a history of migraine headaches prior to concussion will be excluded.
  2. Prior use of any triptan medication for headache.
  3. Use of non-opioid analgesic medications 15 or more days per month for the previous month.
  4. Use of opioid medications more than 10 days in the previous month.

  6. Taking two or more medications from the following medication classes: SSRI, SNRI, or TCA.
  7. Headache prophylactic medication is allowed but must remain unchanged during the study period.
  8. Patients with depression, defined as a PHQ-9 score greater than 15, will be excluded from study participation.
  9. PTSD is NOT an exclusion criterion. PTSD will be defined as a clinical diagnosis by a behavioral health provider or PTSD symptom checklist score of 50 or higher.
  10. Systolic BP > 140 or diastolic BP > 90 on repeated measurements.
  11. Active use of dihydroergotamine.
  12. Known coronary artery disease, prior myocardial infarction, history of stroke or TIA, or liver disease.
  13. Subjects who will not be available for study-related follow-up visits will be excluded.
  14. Patient has cognitive impairment defined as mini-mental status exam score less than 27.
  15. Patients undergoing a medical board for headache, sequelae of TBI, or psychiatric disorders will be excluded.
  16. Patients suspected of malingering, exaggerating symptoms, or non-compliance will be excluded from study participation.
  17. Patient has hemiplegic migraine or basilar migraine.
