Time is considered a critical factor in treating stroke patients because “time is brain”; in the context of a stroke, time lost is brain lost. Because a stroke is caused by a disruption in blood circulation to the brain, every minute that passes without treatment can lead to the death of brain cells and a subsequent loss of function.

The following points illustrate why immediate action is essential:

• The FAST Acronym: The “T” in the FAST acronym stands for Time, signifying that as soon as symptoms—such as facial drooping, arm weakness, or speech difficulties—are recognized, it is time to call for emergency services immediately.
• Immediate Medical Interventions: Rapid response allows for the administration of immediate active medications, such as antiplatelets and neuroprotective agents, which help mitigate damage.
• Advanced Procedures: Time-sensitive procedures like mechanical thrombectomy (a retrieval treatment to remove blockages) are most effective when performed as quickly as possible after the onset of symptoms.
• Preventing Disability: Since stroke is the third leading cause of disability worldwide, seeking treatment at a specialized facility quickly can significantly improve the chances of a successful recovery through neuro-rehabilitation.

In summary, the speed of medical intervention directly correlates with the amount of brain tissue that can be saved and the level of disability a patient may face long-term.
