Which test is essential to distinguish ischemic from hemorrhagic stroke?

• A. To measure blood glucose
• B. To distinguish ischemic from hemorrhagic stroke.
• C. To evaluate kidney function
• D. To measure cholesterol

Answer: (B)

Distinguishing ischemic from hemorrhagic stroke relies on identifying whether there is bleeding in the brain. The essential test is brain imaging, with a non-contrast CT scan being the fastest and most informative first step. It quickly shows whether blood is present, which confirms a hemorrhagic stroke, or shows no bleed, making an ischemic stroke more likely and guiding therapy accordingly. This distinction is crucial because treatments differ dramatically: clot-dissolving or clot-removing approaches are used for ischemic stroke, while those approaches would be dangerous in a hemorrhagic stroke. The other measures listed—glucose, kidney function, and cholesterol—are important for overall patient care and risk assessment, but they do not determine the stroke type.
