Worsening of dizziness impairment is associated with BMX level in patients after mild traumatic brain injury (original) (raw)

Abstract

Over 2 million people suffer from mild traumatic brain injury (mTBI) each year. Predicting symptoms of mTBI and the characterization of those symptoms has been challenging. Biomarkers that correlate clinical symptoms to disease outcome are desired to improve understanding of the disease and optimize patient care. BMX, a member of the TEC family of nonreceptor tyrosine kinases, is upregulated after traumatic neural injury in a rat model of mTBI. The objective of this investigation was to determine if BMX serum concentrations can effectively be used to predict outcomes after mTBI in a clinical setting. A total of 63 patients with mTBI (Glasgow Coma Score [GCS] between13-15) were included. Blood samples taken at the time of hospital admission were analyzed for BMX. Data collected included demographic and clinical variables. Outcomes were assessed using the Dizziness Handicap Inventory (DHI) questionnaire at baseline and 6 weeks post-injury. The participant was asssigned to 'case gr...
