Within which time frame do the symptoms of mild traumatic brain injury usually resolve?

• A. 24 hours
• B. 72 hours
• C. 1 week
• D. 2 weeks

Answer: (B)

After a mild traumatic brain injury, the brain undergoes a temporary metabolic disturbance, but recovery of function usually happens quickly. Most symptoms—like headache, dizziness, fatigue, and difficulty concentrating—tend to improve as the brain’s chemistry and blood flow normalize over the first few days. This is why the typical timeframe people use is about 72 hours: within roughly three days, many individuals have significant relief of symptoms and are returning toward baseline. Of course, individual variation exists, and some people feel better even sooner while others may take a bit longer. If symptoms persist beyond several days, or new red flags appear, further medical evaluation is warranted.
