Which describes the expected symptoms after a mild traumatic brain injury (TBI)?

• A. Low-grade constant headache, slowness in thinking, memory problems, loss of balance, poor coordination, constant exhaustion, sensitivity to light, and irritability
• B. Severe chest pain with sweating
• C. Abdominal pain and vomiting
• D. Shortness of breath with wheezing

Answer: (A)

Mild traumatic brain injury commonly causes subtle cognitive and physical symptoms as the brain recovers. Typical signs include a persistent low-grade headache, slowed thinking or difficulty concentrating, memory problems, balance and coordination difficulties, fatigue, sensitivity to light or noise, and irritability. This cluster reflects how a mild concussion can affect processing, memory, and emotional regulation, along with physical fatigue and sensory sensitivity.

The other options describe symptoms more aligned with non-brain conditions: severe chest pain with sweating suggests a cardiac issue, abdominal pain with vomiting points to gastrointestinal problems, and shortness of breath with wheezing indicates a respiratory or allergic condition. If new red-flag signs appear—repeated vomiting, confusion, weakness on one side, or seizures—seek urgent care.
