In the realm of stroke care, every second counts. Acting swiftly and decisively can make a profound difference in the outcome for individuals experiencing a stroke. Recognising the urgency, medical professionals and public health campaigns emphasise the importance of acting FAST. In this blog post, we will delve into why time is of the essence for stroke care and the significance of the FAST acronym in identifying and responding to stroke symptoms promptly.

Unveiling the reality of stroke

Stroke is a medical emergency caused by disrupted blood flow to the brain. It can result from either a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). In either case, the brain cells are deprived of oxygen and nutrients, leading to their rapid deterioration.

The FAST acronym

FAST is an acronym that serves as a mnemonic device to help individuals quickly identify the most common signs of a stroke. Each letter represents a crucial aspect of stroke symptom recognition:

Face Drooping: Sudden drooping or numbness on one side of the face is a classic indicator of a stroke. Ask the person to smile, and observe if their smile appears uneven.

Arm Weakness: Weakness or numbness in one arm, making it difficult to raise both arms evenly, may indicate a stroke. Ask the person to raise both arms and check for any weakness or lack of coordination.

Speech Difficulty: Slurred speech or difficulty speaking and understanding others are potential signs of a stroke. Request the person to repeat a simple phrase, and listen for any abnormalities or confusion.

Time to Call Emergency Services: If any of the above symptoms are present, it is crucial to call 000 immediately. Time is of the essence in stroke care, and prompt medical attention can save lives and significantly improve outcomes.

The ‘Golden Hour’ and the importance of rapid treatment

The “Golden Hour” is a term frequently used in the context of stroke. It refers to the crucial 60-minute window immediately following the onset of stroke symptoms. During this period, the brain is highly vulnerable to damage, and timely intervention can minimise the extent of injury and improve outcomes. This timely treatment is critical due to several key reasons:

Intravenous Thrombolysis (IVT): Intravenous thrombolysis, commonly known as the clot-busting drug, is a time-sensitive treatment option for ischemic stroke. Administered within a few hours of symptom onset, IVT helps dissolve the blood clot causing the blockage, restoring blood flow to the affected area of the brain. The effectiveness of IVT decreases as time elapses, highlighting the need for early intervention.

Mechanical Thrombectomy: For eligible patients with severe ischemic stroke, mechanical thrombectomy is a highly effective procedure. It involves the removal of the clot using specialised devices inserted through blood vessels. Mechanical thrombectomy is most beneficial when performed within a specific time window, typically within six to 24 hours from symptom onset.

Delaying stroke treatment can have severe consequences for the patient. As time passes, the brain sustains more damage, leading to potential long-term disabilities, cognitive impairments, and even loss of life. Studies have shown that for every minute without treatment, an estimated 1.9 million brain cells are lost. Therefore, every moment wasted increases the risk of permanent brain damage.

Public Awareness and Education

Promoting public awareness about stroke symptoms and the importance of acting FAST is paramount. Educational campaigns emphasising the acronym and its significance can empower individuals to identify strokes promptly and seek immediate medical assistance. Increasing awareness within communities, schools, workplaces, and healthcare settings can save lives and reduce the long-term impacts of stroke.


In stroke care, time is a critical factor that directly influences patient outcomes. Acting FAST by recognizing and responding to stroke symptoms promptly can significantly improve the chances of a positive outcome. Understanding the FAST acronym and seeking immediate medical attention when symptoms arise is crucial. By raising awareness and fostering a sense of urgency, we can collectively make a difference in stroke care and help save lives. Remember, acting FAST can be a life-saving decision in the face of stroke.
