Abstract

ABSTRACT:

Objective: To describe the self-reported effects of incobotulinumtoxinA treatments on migraine-like headache in participants who experienced traumatic brain injury versus Anomalous Health Incidents.

Background: Persistent headache attributed to traumatic injury to the head has been widely recognized as among the most common sequelae of concussion/“mild” traumatic brain injury. Such persistent headaches often have migraine-like characteristics and are typically treated similarly to idiopathic migraine. Patients who have experienced Anomalous Health Incidents have also commonly reported migraine-like headaches, but to our knowledge, no reports describing treatment for persistent headaches attributed to Anomalous Health Incidents have been published.

Methods: We describe the self-reported effects of incobotulinumtoxinA treatments on headache with migraine-like characteristics in 19 participants with traumatic brain injury and 11 who had experienced Anomalous Health Incidents from a single center.

Results: Self-reported benefits from incobotulinumtoxinA treatments were generally similar and statistically indistinguishable between groups. The Headache Impact Test-6 score decreased by a mean of 12 points in the traumatic brain injury group and 9.5 points in the Anomalous Health Incidents group from baseline to peak efficacy (p = 0.43), with concomitant reductions in work/school hours lost (62% vs. 50%) and family/leisure hours lost (75% vs. 33%). Furthermore, reductions…
