Time is of the essence when it comes to stroke treatment. The faster a stroke patient receives medical attention, the better their chances of recovery. This is because a stroke occurs when the brain is deprived of oxygen due to a loss of blood supply, and within just three minutes, brain cells begin to die, leading to permanent damage. The extent of brain damage is directly related to the time the brain is without oxygen, with shorter durations resulting in less damage and longer durations causing more severe and lasting impairment. Therefore, prompt diagnosis and treatment are crucial to salvaging brain function and improving patient outcomes.

The importance of recognising stroke symptoms
Recognising the symptoms of a stroke is critical. A stroke is a medical emergency, and the faster a patient receives treatment, the better their chances of recovery. Time is of the essence as the brain is deprived of oxygen and, for every minute this blood flow is cut off, 1.9 million brain cells die. This is why the time from the first symptom to treatment is one of the most important determinants of the long-term consequences of a stroke.
The "stroke window", "stroke golden hour" or "stroke golden window" refers to the critical time after a stroke when certain medications and treatments are most effective. The sooner a stroke is diagnosed, the sooner treatment can begin, and the better the outcome will be. This is why it is so important to be able to recognise the signs of a stroke, so you can call for emergency care as quickly as possible.
The acronym FAST is a simple test to help people identify stroke symptoms:
- Face – has their face fallen on one side? Can they smile?
- Arms – can they raise both arms and keep them there?
- Speech – is their speech slurred?
- Time – time to call emergency services if you see ANY of these signs
Strokes can be difficult to recognise, and symptoms can be mistaken for a 'funny turn'. However, strokes are the fourth largest cause of death in England, and they cause a greater range of disabilities than any other condition in the UK. Over half of all survivors have a disability, and more than a third are left dependent on others for everyday activities. Since the Act FAST campaign launched in 2009, an additional 41,382 people in the UK who have had a stroke have been admitted to hospital within the vital three-hour window, giving them a greater chance of recovery.

The impact of time on brain damage
Time is of the essence when it comes to stroke treatment. The faster a stroke patient receives treatment, the better their outcome is likely to be. This is because a stroke occurs when the brain is deprived of the oxygen it needs to function, and the longer the brain goes without oxygen, the more permanent brain damage is likely to occur.
The phrase "time is brain" is often used to convey the critical nature of time in stroke treatment. For every minute that the brain is deprived of necessary blood flow, 1.9 million brain cells die. This means that the time from the first symptom to the start of treatment is one of the most important factors in determining the long-term consequences of a stroke.
The first few hours after stroke symptoms appear are the most critical, and this period is sometimes referred to as the "stroke golden hour" or "stroke golden window". During this time, it is essential that the patient receives an accurate diagnosis and immediate treatment to improve their chances of survival and prevent long-term damage or disability.
The type of stroke, whether ischemic or hemorrhagic, will determine the course of treatment. Ischemic strokes, which are caused by a blood clot blocking blood flow in the brain, are often treated with clot-busting medications such as tissue plasminogen activator (tPA) or alteplase. These medications need to be given within three hours of the onset of symptoms, and in some cases, this window can be extended to four and a half hours or more. Hemorrhagic strokes, on the other hand, are caused by a ruptured blood vessel, and treatment involves controlling the bleeding in the brain and reducing blood pressure.

The role of paramedics and EMTs in stroke care
Stroke is a medical emergency that requires prompt recognition and treatment. Paramedics and Emergency Medical Technicians (EMTs) play a crucial role in the early identification, assessment, and management of stroke patients, which can significantly impact patient outcomes.
When responding to a suspected stroke, paramedics and EMTs are often the first healthcare providers to evaluate and manage the patient. They are trained to recognise the signs and symptoms of stroke, which can include face drooping, arm weakness, speech difficulties, sudden numbness or weakness on one side of the body, confusion, vision problems, dizziness, and severe headache. A systematic assessment framework, such as the ABCDE (Airway, Breathing, Circulation, Disability, and Exposure) approach, is used to guide their initial evaluation and management.
One of the critical aspects of stroke care is determining the time of onset of symptoms. This information is vital for hospitals, as it helps guide treatment decisions, particularly for thrombolytic therapy, which has a narrow therapeutic window. Paramedics and EMTs play a key role in establishing this timeline by interviewing the patient, witnesses, or bystanders.
In addition to assessing vital signs and managing the patient's airway, breathing, and circulation, paramedics and EMTs may also perform a neurological exam to assess the patient's neurologic status. They may use validated prehospital stroke scales, such as the Cincinnati Prehospital Stroke Screen or the Los Angeles Prehospital Stroke Screen, to aid in their evaluation.
Furthermore, paramedics and EMTs are responsible for initiating early stroke management in the prehospital setting. This includes administering oxygen therapy to patients with hypoxia, monitoring vital signs, and establishing intravenous access. They also play a crucial role in coordinating with the receiving hospital, providing timely updates, and ensuring a smooth transition of care upon arrival.
In some cases, paramedics have been involved in administering stroke therapies, such as magnesium sulfate, in the prehospital setting, as seen in the FAST-MAG clinical trial. This approach highlights the potential for paramedics to provide early interventions that can improve patient outcomes.
Overall, the role of paramedics and EMTs in stroke care is vital in ensuring prompt identification, assessment, and management of stroke patients. Their timely interventions and coordination with hospitals contribute significantly to optimising patient outcomes and reducing the long-term consequences of stroke.

The significance of timely treatment for stroke patients
A stroke is a medical emergency that requires immediate attention. The faster a stroke patient receives treatment, the better their chances of recovery and reducing potential long-term damage. Timely treatment can be the difference between life and death, as well as the difference between full recovery and permanent disability.
The "time is brain" philosophy underscores the critical nature of time in stroke treatment. Every minute a stroke patient's brain is deprived of oxygen and necessary blood flow, approximately 1.9 million brain cells die. The extent of brain damage is directly correlated with the duration of time the brain is without oxygen. Therefore, minimising delays and receiving treatment as soon as possible is of utmost importance.
The first few minutes and hours after stroke symptoms appear are crucial. Recognising the signs of a stroke and acting fast can significantly improve outcomes. The acronym FAST is a simple test to help identify stroke symptoms:
- Face: Has their face fallen on one side? Can they smile??
- Arms: Can they raise both arms and keep them there?
- Speech: Is their speech slurred?
- Time: If you observe any of these signs, it's time to call emergency services.
Once a stroke patient arrives at the hospital, an accurate and rapid diagnosis is vital. Diagnostic imaging tests, such as CT scans, help determine tissue damage and guide treatment decisions. The recommended time frame for initiating treatment is within three hours of symptom onset, known as the "stroke golden hour" or "stroke window." This timeframe can be extended to four and a half hours in some cases.
The type of stroke, ischemic or hemorrhagic, determines the course of treatment. Ischemic strokes, caused by blood clots, are often treated with clot-busting medications like tissue plasminogen activator (tPA), while hemorrhagic strokes, caused by ruptured blood vessels, may require surgical intervention to control bleeding and reduce blood pressure.
In conclusion, timely treatment for stroke patients is of paramount importance. The faster a stroke is diagnosed and treated, the better the chances of recovery and minimising long-term disabilities. By recognising the signs of a stroke and acting quickly, we can improve patient outcomes and potentially save lives.

The long-term effects of stroke
The long-term effects of a stroke depend on the location and extent of the damage to the brain tissue. The brain is the central organ of the human nervous system, controlling both motor and sensory functions throughout the body. If a stroke occurs and blood flow is cut off to a particular region of the brain, that part of the body will be affected.
A stroke on the left side of the brain will affect the right side of the body, and vice versa. A stroke towards the back of the brain will likely result in some form of visual impairment. A stroke in the left hemisphere of the brain can cause paralysis and sensory changes on the right side of the body, as well as speech and language problems, and issues with thinking and memory. A stroke in the right hemisphere can cause paralysis and sensory changes on the left side of the body, spatial thinking or imagery issues, and problems with thinking and memory.
The effects of a stroke in the brain stem can be severe, sometimes resulting in a 'locked-in' state, where the patient is conscious but unable to speak or move due to muscle paralysis.
The time it takes to receive treatment after the first symptoms of a stroke appear is critical in determining the long-term consequences. The longer the brain is deprived of oxygen, the more permanent the brain damage will be. Therefore, recognising the signs of a stroke and seeking immediate emergency care are crucial in minimising long-term disability.
The long-term complications of a stroke can be grouped into medical, musculoskeletal, and psychosocial domains. Medical complications include post-stroke seizures, urinary and faecal incontinence, and cognitive impairment. Musculoskeletal issues include spasticity, hypertonicity, and pain in the hemiplegic shoulder and wrist. Psychosocial complications are also common, with post-stroke depression and emotional changes such as frustration, anxiety, and anger affecting many patients.
