This article by Yida He and colleagues takes a closer look at repetitive subconcussions (SC), a mild traumatic brain injury, and its role in causing primary headache disorders such as long-term synaptic dysregulation and executive dysfunction. This study aims to improve understanding of SC-based headaches and provide markers for early identification. The participants consisted of sixteen military paratroopers aged 18-25 years and sixteen demographically matched healthy controls from Wuhan universities. EEG data was then recorded, filtered, and processed before classification. Classification was conducted for each participant who experienced one or more of four corresponding microstates: alpha, beta, theta, and delta. This was to ensure state-specific analysis to determine whether the structure of certain networks under these specific conditions can distinguish between subjects exposed to SC from the healthy individuals. All four of the tested networks resulted in favorable classification performance when differentiating between the healthy and SC groups. The result of this experiment proved a marker for central sensitization, where there is a failure in coordination between the waves of sensory input and regulatory mechanisms. Other similar uncoordinated wave patterns were also observed to be associated with certain symptoms of fibromyalgia and functional somatic disorders.
