Headaches, dizziness, and excessive fatigue BEST identify which condition?

• A. Dehydration
• B. Heat stroke
• C. Migraines
• D. Concussion

Answer: (D)

Headache, dizziness, and excessive fatigue together point most strongly to a concussion, especially when there’s any history of head impact. A concussion is a mild traumatic brain injury, and its common early signs include a persistent headache, balance problems or dizziness, and a feeling of fatigue or slowed thinking. These symptoms can show up right away or develop hours to days after the injury, which is why this combination is a classic pattern for concussion.

Dehydration, for contrast, would typically bring thirst and dry mouth, dark urine, and sometimes dizziness, but isn’t defined by a trio of headaches with fatigue. Heat stroke involves very high body temperature, hot or red skin, and often confusion or collapse. Migraines can include headache with nausea and sensitivity to light or sound, sometimes with aura, but fatigue alone isn’t the defining cluster.
