Which of the following is a differential diagnosis for seizures?

• A. Asthma
• B. Migraine
• C. Hypoglycemia
• D. Hypertension

Answer: (C)

When evaluating seizures, clinicians look for metabolic disturbances that can provoke abnormal brain activity. Hypoglycemia is a classic trigger because the brain relies on glucose for energy; when blood sugar falls, neuronal function becomes unstable and seizures can occur. That makes hypoglycemia a standard part of the differential diagnosis for seizures, and rapid glucose testing with prompt treatment is a priority in the workup. The other options don’t directly provoke seizures: asthma is a lung condition, migraine is a primary headache disorder (though it can sometimes resemble seizure symptoms), and hypertension relates to blood pressure problems (which can lead to strokes or other neurologic issues, but not a typical seizure trigger).
