What is the purpose of the "Time" in the FAST stroke acronym?

The purpose of "Time" in the FAST stroke acronym is to stress the importance of timing in calling emergency services. In the context of a stroke, every minute counts. The faster a person who is experiencing a stroke receives medical treatment, the better their chances are for a favorable outcome and recovery. It is crucial for bystanders and those witnessing stroke symptoms to recognize the urgency of the situation. Promptly notifying emergency services can significantly impact the treatment options available, as certain interventions must be administered within specific time frames to be effective. Identifying the onset of symptoms and stating the time they appeared becomes vital in guiding the healthcare professionals in providing the most effective treatment promptly.
