More than 50,000 children are hospitalized each year nationwide with an acquired brain injury, according to research. Teachers can expect to have at least one student with history of a concussion or head injury in their class each year. A traumatic brain injury, or TBI, is caused by a blow, bump, or jolt to the head or body and can cause physical, cognitive, and perception symptoms—things like headaches, nausea, confusion or disorientation, changes in sleep patterns, frustration and irritability, sensitivity to light and sound, or fatigue. Here is a downloadable tip sheet spells out advice for educators to consider when they have a student in their class who suffers from a concussion or TBI.
