What is the typical initial assessment for a patient presenting with a new-onset seizure in adults?

• A. Airway, breathing, circulation; glucose check; neurological exam; basic metabolic panel; head imaging as indicated; review of current meds and withdrawal risks.
• B. MRI only.
• C. Observation.
• D. No assessment.

Answer: (A)

In an adult with a new-onset seizure, the immediate goal is to stabilize the patient and identify reversible contributors. Start with airway, breathing, and circulation to ensure the person can oxygenate and remain hemodynamically stable, because hypoxia or poor perfusion can worsen brain injury and seizure risk. Quickly check blood glucose because abnormal glucose levels—especially hypoglycemia—can both trigger seizures and complicate recovery, and treat as needed. A focused neurological exam establishes a baseline and helps detect focal deficits or a postictal state that guide further testing. A basic metabolic panel is then useful to assess electrolytes, kidney function, calcium and magnesium, and acid-base status since electrolyte disturbances and metabolic issues are common seizure triggers. Head imaging is indicated in the acute setting to rule out intracranial pathology such as hemorrhage or mass effect that would require urgent management. Finally, review all medications and withdrawal risks, including recent changes, alcohol or sedative withdrawal, and potential drug interactions, because identifying and addressing these precipitants is key to preventing recurrence. Skipping stabilization, rapid metabolic assessment, imaging, or medication review misses critical factors and can delay essential treatment.
