What term means injury to the brain caused by a blow?

• A. Concussion
• B. Meningitis
• C. Encephalitis
• D. Hyperesthesia

Answer: (A)

Concussion refers to a brain injury caused by a blow to the head or a sudden jolt that shakes the brain. It’s considered a mild traumatic brain injury and can cause temporary disruption of brain function, with signs like headache, confusion, dizziness, or sometimes loss of consciousness or memory gaps. It’s due to trauma, not an infection or inflammation. Meningitis is an infection of the protective coverings of the brain and spinal cord. Encephalitis is inflammation of brain tissue, usually from infection or autoimmune processes. Hyperesthesia means an abnormal increase in sensitivity to sensory stimuli. So the term that specifically means injury to the brain from a blow is concussion.
