A jolt or blow to the head that disrupts brain function defines which condition?

• A. A minor headache with no lasting effects
• B. A jolt/blow to the head that disrupts brain function
• C. A skull fracture
• D. A temporary dizziness

Answer: (B)

A concussion is a mild traumatic brain injury caused by a jolt or blow to the head that disrupts brain function. That disruption means the brain isn’t working normally for a short time, which can show up as confusion, memory problems, dizziness, headache, nausea, sensitivity to light or noise, or even brief loss of consciousness. It’s not just a simple headache or dizziness—those symptoms can occur with many things, but a concussion specifically involves a temporary change in brain function. It’s also not a skull fracture, which is a break in the skull itself. In the field, recognizing when brain function has been disrupted helps you decide to remove the person from duty and seek medical evaluation if concussion is suspected.
