NEW ORLEANS—More than two-thirds of postconcussive headaches in children are classified as migraines, according to research presented at the 64th Annual Meeting of the American Academy of Neurology.
“Migraines comprise a far greater percentage of postconcussive headaches than previously reported,” said John A. Pugh, MD, PhD, of the Cincinnati Children’s Hospital Medical Center, and colleagues.
Prior studies have indicated that tension headaches were the most prevalent type of headache seen after a concussion, but that conclusion was “at odds with our personal experience,” stated the researchers.
To better classify postconcussive headaches in children, the investigators retrospectively reviewed the charts of 104 patients ages 10 to 21 who were seen at the Cincinnati Children’s Hospital Medical Center Concussion Clinic between January 2008 and June 2011.
The 75 patients included in the analysis (58% male) presented within three months following a concussion and had a mean age of 14.7. Data were gathered on patients’ medical history, circumstances surrounding the concussion, and predominant headache type according to International Classification of Headache Disorders (ICHD)-II criteria, which categorize headaches as migraine, tension, or other.
