Post-traumatic headache phenotype and recovery time after concussion
In a recent study published by JAMA Network Open, Gerard Gioia, Ph.D., division chief of Neuropsychology and director of Safe Concussion Outcome, Recovery and Education (SCORE) Program at Children’s National Hospital, along with other leading researchers, described the characteristics of youth with post-traumatic headache (PTH) and determine whether the PTH phenotype is associated with outcome.
Concussions and mild traumatic brain injuries (mTBI) are common among children and adolescents and constitute a major public health challenge. While symptoms from a concussion typically resolve days to weeks after injury, 10% to 30% of patients have symptoms that last longer than four weeks, and a smaller proportion have symptoms that persist for much longer.
PTH is defined as significantly worsened head pain attributed to a blow or force to the head. Although adolescents have a higher risk for sustaining concussions and developing persistent symptoms than younger children or adults, there is little data regarding PTH recovery and treatment in youth.
Dr. Gioia founded the multicenter Four Corners Youth Consortium to fill the gap in our understanding of youth concussion and recovery. This study is the first analysis of PTH phenotype and prognosis in this cohort of concussed youth.
The researchers analyzed headache-related symptoms from a validated questionnaire developed by Dr. Gioia and his Children’s National concussion research team. The primary outcomes were time to recovery and concussion-attributable headache three months after injury while the secondary outcome was headache six months after injury. Recovery was defined as resolution of symptoms related to a concussion.
Future large studies validating the classification of posttraumatic headache phenotypes in youth and studying outcomes are essential. PTH phenotyping will improve prognostication of concussion recovery and will enhance the treatment for PTH with more appropriate and targeted therapies to treat and prevent persistent and disabling headaches in youth with a concussion.
