Why is fever control important after acute ischemic stroke?

• A. Fever worsens outcomes; aggressive monitoring and antipyretics or cooling as needed
• B. Fever is protective after stroke
• C. Fever has no impact on outcome
• D. Only treat fever if patient requests

Answer: (D)

Fever after an acute ischemic stroke worsens brain injury and recovery outcomes. Elevated temperature increases the brain’s metabolic demands at a time when blood flow is already compromised, which can expand the area of injury and intensify inflammatory responses. This helps explain why fever is linked to larger infarct size, worse functional outcomes, and higher risk of complications like infections and delirium. Because of these risks, fever control is important: monitor temperature closely and use antipyretics to bring temperature down, with cooling methods considered if fever persists or becomes high. The other statements don’t fit because fever is not protective, it does impact outcomes, and fever should be treated proactively rather than only on patient request.
