According to the Brain Injury Research Institute, approximately 1.6 million to 3.8 million concussions occur each year. Post-traumatic headache (PTH) is said to be the most common symptom following a concussion. The International Headache Society defines PTH as “a headache developing within seven days of the injury or after regaining consciousness.” With physical activity on the rise and an increasing life expectancy, both the young and the old are at risk of receiving a head injury. We do not know the probability of developing PTH after a concussion, but we are hoping a study at Mayo Clinic that compares structural brain changes in PTH patients and healthy controls will provide some answers. As part of my internship at Mayo, I will have the opportunity to act as an observer and get a firsthand look at clinical trials involving PTH patients. Using more advanced computer technology, we will sequence MRI scans in order to segment and parcellate specific areas of the brain. From there, the images will help us to identify the significance of these brain changes as well as provide reasoning for further research. It’s important that coaches, parents, and teachers know what it means to have a concussion and the possible repercussions of getting one. The more people are well-informed about the seriousness of concussions, the better.
