Neurological Institute Outcomes

In 2021, 3026 patients with chronic migraine completed at least 1 questionnaire following treatment, with a median interval between initial appointment and follow-up of 189 days (range, 7-651). Of the 2342 patients who reported HIT-6 scores > 50 at initial evaluation (higher scores indicate greater impairment secondary to headache pain¹), 74% improved or remained stable. Of the 1214 patients who reported initial PROMIS² pain at or above the median score of 6, 88% improved or remained stable. Of the 932 patients who reported initial depressive symptoms ≥ 10 points for the PHQ-9 (higher scores indicate greater depression³), 30% reported improvement at follow-up.
