Brain Injury Awareness Month is observed each March. The purpose of this is to bring awareness to brain injuries, often referred to as TBIs (traumatic brain injuries), concussions, or ABIs (acquired brain injuries). TBIs are often caused by external factors. These could include car accidents, sports, and falls. They are often categorized by severity, ranging from mild to severe. Concussions are a form of mild TBIs. ABIs are injuries to the brain that are not caused by genetics or birth trauma. These could include stroke, seizures, meningitis, or other infectious diseases. You may have also heard of or seen chronic traumatic encephalopathy (CTE), which is a progressive and fatal brain disease after repeated TBIs.
