What are the two age peaks for traumatic brain injury (TBI)?

• A. Birth to 4 years, and 15 to 19 years
• B. 0 to 2 years, and 10 to 12 years
• C. 5 to 9 years, and 20 to 25 years
• D. 12 to 16 years, and 25 to 30 years

Answer: (A)

Traumatic brain injury tends to show a bimodal distribution, with two distinct high-risk periods. The first is in early childhood, roughly from birth to about 4 years, when falls and injuries from exploring activities are common and safety awareness is still developing. The second peak occurs in adolescence, around ages 15 to 19, when risk-taking, sports, vehicle-related crashes, and momentary lapses in judgment increase exposure to head injuries. The option that spans birth to 4 years and 15 to 19 years matches these two well-established high-risk periods. Other ranges miss one of these peaks or misplace it, so they don’t fit the typical pattern of TBI incidence.
