A stroke occurs when the blood supply to part of the brain is interrupted or a blood vessel in the brain ruptures. Without an adequate supply of oxygen and nutrients, brain cells begin to become damaged. The effects depend on which part of the brain is affected, how much tissue is involved and how quickly treatment begins.
A stroke may cause sudden weakness, difficulty speaking, changes in vision or loss of balance. These symptoms can appear dramatically, but they are not always recognised immediately. Some people assume that the person is tired, confused or simply unwell, particularly when the symptoms are less obvious.
This uncertainty can cost valuable time.
A stroke is a medical emergency. Recognising its warning signs and seeking treatment immediately can help save brain tissue, reduce disability and improve the chances of recovery.
Understanding stroke also means knowing what can be done before it happens, how treatment decisions are made in an emergency and why recovery often continues long after the initial hospital treatment.
What Is World Stroke Day and Why Is Stroke Awareness Important?
World Stroke Day is observed every year on 29 October to raise awareness about stroke, its prevention, its warning signs and the needs of people living with its consequences.
The importance of this awareness is reflected in one sobering fact: approximately one in four adults is at risk of experiencing a stroke during their lifetime.
Stroke can affect people of different ages, although the risk generally increases with age. Its consequences may extend beyond physical weakness to affect speech, memory, thinking, emotional well-being and independence.
Awareness matters for two distinct reasons.
- Before a stroke: Recognising and managing risk factors can help reduce the likelihood of an event.
- When a stroke occurs: Recognising the symptoms and obtaining emergency care can influence treatment options and recovery.
Stroke awareness is therefore not limited to knowing the symptoms. It also involves understanding how to reduce risk and what recovery may require.

What Is the World Stroke Day 2026 Campaign and Why Does Every Minute Count?
The World Stroke Organization's 2026 campaign continues the message:
“Every M1nute Counts” — #ActFAST
The focus is on the life-saving importance of recognising stroke symptoms and seeking emergency medical care without delay.
Why is time so important?
Brain cells depend on a continuous supply of oxygen and nutrients. When blood flow is interrupted, the affected tissue begins to suffer injury. The longer the interruption continues, the greater the potential for permanent damage.
However, the relationship between time and treatment is not simply a countdown to a fixed deadline.
Earlier treatment generally offers the best opportunity to limit brain injury, but some patients may still be eligible for specialised treatment after several hours. Eligibility depends on the type of stroke, the time course, imaging findings and other clinical factors.
This is why nobody should assume that treatment is no longer possible because some time has already passed.
The right response is to seek emergency care immediately.
In stroke, time is not merely a matter of convenience. It can influence how much brain function can be preserved.
What Happens During a Stroke?
The two main types of stroke have different causes, and this distinction directly affects treatment.
- Ischaemic Stroke
An ischaemic stroke occurs when a blood clot or another blockage interrupts blood flow through an artery supplying the brain. Without adequate circulation, the affected brain tissue begins to suffer damage.
Treatment may involve medicines that dissolve a clot or a procedure to remove it in appropriately selected patients.
- Haemorrhagic Stroke
A haemorrhagic stroke occurs when a blood vessel ruptures and blood leaks into or around the brain. The bleeding can damage brain tissue and increase pressure within the skull.
Treatment focuses on controlling the bleeding and its effects. Some patients require specialised neurosurgical or endovascular procedures.
These two types can produce similar symptoms, but their treatment is different.
A medicine appropriate for a stroke caused by a clot can be dangerous in a stroke caused by bleeding. That is one reason urgent brain imaging is essential before doctors decide on treatment.

What If the Symptoms Disappear on Their Own?
A transient ischaemic attack (TIA) causes stroke-like symptoms that resolve as blood flow returns. It is sometimes called a mini-stroke, but that term can make the event sound less serious than it is.
A TIA can be a warning that a more disabling stroke may follow.
Even if the symptoms disappear completely, the person needs urgent medical assessment. Do not wait for the symptoms to return.
What Are the Early Warning Signs and Symptoms of a Stroke?
Stroke symptoms usually appear suddenly. They may involve movement, speech, vision, balance or other brain functions.
The FAST method is a useful way to recognise some of the most important warning signs.
F: Face Drooping
One side of the face may droop or feel numb. Ask the person to smile and look for an uneven smile.
A: Arm Weakness
One arm may suddenly become weak or numb. Ask the person to raise both arms and see whether one drifts down.
S: Speech Difficulty
Speech may become slurred or difficult to understand. The person may struggle to speak or understand what others are saying.
T: Time to Seek Emergency Help
If any of these signs appear suddenly, seek emergency medical care immediately. Do not wait to see whether they improve.
Stroke can also present with other sudden symptoms, including:
- Loss of balance, coordination or the ability to walk normally
- Blurred vision, double vision or sudden loss of vision
- Numbness or weakness affecting one side of the body
- New confusion or difficulty understanding speech
- A sudden, severe headache without an apparent cause
Not every stroke produces all these symptoms. Some affect balance or vision without obvious facial drooping or arm weakness.
The sudden onset of an unfamiliar neurological symptom deserves urgent attention, even when it does not fit the classic FAST pattern.
What Should You Do If Someone Shows Signs of a Stroke?
The most important action is to obtain emergency medical care immediately.
Do not wait for a family doctor appointment, try home remedies or see whether the person feels better after resting.
What to Do Immediately
- Call emergency medical services. Tell the responder that you suspect a stroke and describe the symptoms.
- Note when the symptoms began. If the exact time is unknown, note when the person was last seen behaving normally. This information can influence treatment eligibility.
- Keep the person safe and under observation. Help them sit or lie safely while waiting for emergency assistance.
- Do not give food, water or oral medicines. A stroke can affect swallowing, and some medicines can be dangerous before the stroke type is known. Do not give aspirin unless a clinician directs you to.
- Follow the emergency team's instructions. Arrange prompt transfer to a hospital equipped to assess and treat stroke.
An Important Point About the Time of Onset
If someone wakes up with stroke symptoms, do not assume that treatment is impossible because the exact onset time is unknown. The medical team can use the available history and appropriate imaging to assess the situation.
The purpose of these steps is not to diagnose the stroke at home.
It is to preserve the opportunity for timely treatment by avoiding preventable delays.
What Are the Major Risk Factors for Stroke?
Stroke risk is influenced by medical conditions, lifestyle and factors that cannot be changed.
Some of the most important risks are manageable, which makes their early identification particularly valuable.
| Risk factor | Why it matters |
| High blood pressure | A major modifiable risk factor associated with both blocked-vessel and bleeding strokes. |
| Diabetes | Can damage blood vessels and increase cardiovascular risk. |
| High cholesterol | Can contribute to the formation of plaques in arteries. |
| Atrial fibrillation | An irregular heart rhythm that can allow clots to form and travel to the brain. |
| Smoking and tobacco use | Damage blood vessels and increase the risk of clot formation. |
| Physical inactivity and excess weight | Can contribute to high blood pressure, diabetes and other vascular risks. |
| Harmful alcohol use | Can contribute to hypertension and other factors associated with stroke. |
Other factors include increasing age, family history, certain heart and blood vessel conditions, and a previous stroke or TIA.
A previous stroke is particularly important because it increases the risk of another event. The factors that caused the first stroke need to be investigated and addressed as part of follow-up care.
Why Is High Blood Pressure So Important?
High blood pressure often produces no obvious symptoms. A person may feel entirely well while prolonged pressure places stress on blood vessel walls.
Over time, this can contribute to vessel damage, narrowing, blockage or rupture.
Feeling healthy is not a reliable way to know whether blood pressure is controlled. Regular measurement and appropriate treatment matter even when there are no symptoms.
How Can Stroke Be Prevented?
Stroke prevention is largely about identifying individual risks and managing them consistently, often long before any symptoms appear.
- Keep Blood Pressure Under Control
Have your blood pressure checked regularly and follow the treatment plan recommended by your doctor. Do not stop prescribed medicines simply because you feel well.
- Manage Diabetes and Cholesterol
Regular monitoring and appropriate treatment can help reduce damage to blood vessels. The targets and medicines should be tailored to your overall cardiovascular risk.
- Identify Heart Rhythm Problems
Atrial fibrillation can cause clots to form in the heart and travel to the brain. When present, it may require specific treatment, including anticoagulant medicines for eligible patients.
- Avoid Tobacco and Limit Alcohol
Stopping smoking and avoiding tobacco are important steps towards protecting blood vessels. Avoiding harmful alcohol use also reduces associated health risks.
- Maintain Regular Physical Activity and a Balanced Diet
Regular movement, a balanced diet with less excess salt, and maintaining a healthy weight can help control several stroke risk factors at once.
- Take Prescribed Preventive Medicines Consistently
People who have previously had a stroke or TIA may need specific preventive medicines, depending on the cause of the event. These may include antiplatelet medicines or anticoagulants, but they are not interchangeable.
Do not start, stop or change blood-thinning medication without medical advice. The correct approach depends on the type and cause of the stroke.
Prevention is not a single intervention. It is the combined effect of identifying risk, treating it appropriately and maintaining follow-up.

How Is Stroke Diagnosed and Treated?
When stroke is suspected, the medical team has two immediate priorities:
Confirm what is happening in the brain and determine which treatment is safe and appropriate.
How Is a Stroke Diagnosed?
Assessment may include:
- A neurological examination to identify affected functions
- A review of when symptoms started and the person's medical history
- Emergency CT or MRI of the brain
- Blood tests, including a blood glucose measurement
- Blood vessel imaging when indicated
- Heart rhythm assessment and other investigations to identify the cause
A CT scan is often performed rapidly to help distinguish bleeding from a blockage. Additional imaging may be needed to examine blood vessels, identify the affected brain tissue or guide decisions about specialised treatment.
How Is an Ischaemic Stroke Treated?
For eligible patients, thrombolysis uses clot-dissolving medicine to help restore blood flow. These medicines are generally considered within a short treatment window, commonly up to 4.5 hours from symptom onset, depending on the patient and clinical criteria.
A procedure called mechanical thrombectomy may be used to remove a clot from a large artery supplying the brain. Selected patients may benefit from this treatment up to 24 hours from when they were last known to be well, based on clinical assessment and imaging.
These are not universal treatment windows for everyone. Eligibility depends on several factors, and treatment should begin as early as possible.
How Is a Haemorrhagic Stroke Treated?
Treatment focuses on controlling the bleeding, managing blood pressure and pressure within the skull, and addressing the cause of the haemorrhage. Some patients require neurosurgical or endovascular intervention.
The key point is that stroke treatment cannot be chosen safely until the medical team has established the type of stroke and assessed the patient's condition.
After the emergency has been managed, treatment also includes preventing complications and planning rehabilitation.
What Rehabilitation Is Needed After a Stroke?
The end of emergency treatment is not necessarily the end of stroke care.
A stroke may affect movement, balance, speech, swallowing, memory, attention, mood or the ability to perform everyday activities. Rehabilitation is designed around the particular functions affected and the person's goals.
Rehabilitation May Involve
- Physiotherapy: To help improve strength, balance, walking and movement.
- Occupational therapy: To support everyday tasks such as dressing, bathing, eating and returning to work or household activities.
- Speech and language therapy: To address communication difficulties and, when needed, swallowing problems.
- Cognitive rehabilitation: To work on attention, memory, planning and other thinking skills.
- Psychological support: To help address changes in mood, adjustment and emotional well-being.
- Caregiver education: To help family members support recovery safely and understand changing care needs.
Rehabilitation generally begins when the patient's medical condition allows, with its pace and intensity adapted to the individual's needs.
Recovery is different for every person. Some regain many of their previous abilities, while others continue to need support. Progress can also continue beyond the initial hospital stay.
Rehabilitation is not simply about recovering movement. It is about regaining as much independence and participation in everyday life as possible.
When Should You Consult a Neurologist for Stroke-Related Concerns?
A suspected acute stroke is an emergency, not a routine specialist appointment. Call emergency services rather than waiting for an outpatient consultation.
A neurologist also has an important role after the initial emergency, helping investigate the cause, plan prevention and manage the neurological effects of stroke.
Specialist follow-up is particularly important when:
- The person has had a stroke or TIA and needs evaluation to reduce the risk of another event.
- Weakness, speech difficulties, balance problems or other neurological symptoms persist.
- The cause of the stroke remains uncertain.
- Risk factors such as atrial fibrillation or other vascular conditions require ongoing management.
- Rehabilitation and long-term neurological care need coordination.
The aim is to understand why the stroke occurred, address the risks that can be changed and support the person's recovery.
