Anyone can have a stroke at any age, but the risk increases as you get older. Strokes are most common among people in their 90s, with the average age of stroke patients being in the 70s. The risk of a stroke increases most dramatically after the age of 60, with the mean age being 74.3 according to a UK study. While strokes are rare in children and adolescents, they do happen, with researchers estimating 1 to 2 cases per 100,000 children each year.

Anyone can have a stroke at any age, but certain factors can increase your chances of having one. While you can't control your age or family history, you can take steps to lower your chances of having a stroke.
Obesity
Obesity is linked to higher levels of "bad" cholesterol and triglycerides, as well as lower levels of "good" cholesterol. It can also lead to high blood pressure and diabetes, which are risk factors for stroke. Abdominal obesity, in particular, is the form of obesity most strongly associated with metabolic syndrome, which significantly increases the risk of stroke.
High blood pressure
High blood pressure is a leading cause of stroke. It occurs when the pressure of the blood in your arteries is too high, affecting your heart, kidneys, and brain. It is often called a "silent killer" because it usually has no symptoms. However, getting your blood pressure checked regularly and making lifestyle changes or taking medication can help lower your risk of stroke.
Diabetes
Diabetes causes sugar to build up in the blood, preventing oxygen and nutrients from reaching the brain and other parts of the body. It is also associated with high blood pressure, which is the leading cause of stroke. Controlling diabetes through medication, lifestyle changes, and a healthy diet can help reduce the risk of stroke.
High cholesterol
Cholesterol is a waxy, fat-like substance produced by the liver and found in certain foods. When consumed in excess, it can build up in the arteries, including those in the brain, leading to narrowing and blockage. This can increase the risk of stroke. A simple blood test can determine if you have high cholesterol, and lifestyle changes, such as a healthy diet and regular exercise, can help lower cholesterol levels.
Smoking
Tobacco use increases the risk of stroke by damaging the heart and blood vessels. Nicotine raises blood pressure, and carbon monoxide from cigarette smoke reduces the amount of oxygen in the blood. Quitting smoking is one of the most effective ways to lower your risk of stroke and improve your overall health.
Drinking
Excessive alcohol consumption can raise blood pressure levels and increase the risk of stroke. It also increases triglyceride levels, a form of fat in the blood that can harden the arteries. Limiting alcohol intake to no more than one drink per day for women and no more than two drinks per day for men is recommended to reduce the risk of stroke.

A stroke is a life-threatening condition that occurs when the brain doesn't receive enough blood flow. While strokes are more common in older adults, they can happen at any age, even in babies, children, and adolescents.
Strokes are mainly caused by two things: ischemia and hemorrhage. Ischemia occurs when blood vessels in the brain are blocked, cutting off blood flow. This accounts for about 80% of strokes. Hemorrhage, on the other hand, causes bleeding in or around the brain.
Ischemic Stroke
Ischemic strokes are usually caused by blood clots, which can form due to various factors such as:
- Atrial fibrillation, especially when caused by sleep apnea
- Heart defects such as atrial or ventricular septal defects
- Microvascular ischemic disease, which can block smaller blood vessels in the brain
Hemorrhagic Stroke
Hemorrhagic strokes are often caused by:
- High blood pressure, especially when it is long-term, very high, or both
- Brain aneurysms
- Brain tumors
- Diseases that weaken or cause unusual changes in blood vessels in the brain, such as moyamoya disease
Risk Factors
Additionally, certain factors and medical conditions can increase the risk of stroke:
- Age: While strokes can occur at any age, the risk increases as you get older, especially after 50.
- Race: People from Black or South Asian backgrounds may have a higher risk.
- Medical conditions: High blood pressure (hypertension), high cholesterol (hyperlipidemia), Type 2 diabetes, irregular heart rhythms (atrial fibrillation), and a history of stroke or heart attack are all risk factors.
- Lifestyle: An unhealthy lifestyle, including smoking, tobacco use, drug misuse, and excessive alcohol consumption, can increase the risk of stroke.
- Pregnancy: Pregnant individuals with pre-eclampsia or those who have recently given birth are at a higher risk.

A stroke can happen to anyone, at any age, and can be life-threatening. It occurs when the blood supply to the brain is interrupted, resulting in brain cell damage or death. It is important to recognise the signs and act fast as early treatment is critical to improving survival and disability rates.
Stroke Symptoms
The most common symptoms of a stroke include:
- Loss of balance or coordination: A stroke can change the way your brain controls balance, making you feel unsteady or uncoordinated.
- Vision issues: There may be difficulty focusing, double vision, or eye movement problems.
- Arm weakness: One arm may feel weak or numb, and may drift downward when trying to raise both arms.
- Speech difficulty: Speech may be slurred, and the person may have trouble understanding speech.
Other symptoms include:
- Numbness or weakness on one side of the body
- Confusion
- Trouble swallowing
- Severe headache
- Nausea and vomiting
- Unconsciousness
Warning Signs
The acronym F.A.S.T. is often used to spot a stroke:
- Face Drooping: Does one side of the face droop or is it numb? Ask the person to smile.
- Arm Weakness: Is one arm weak or numb? Ask the person to raise both arms.
- Speech Difficulty: Is the person's speech slurred?
- Time to call 999 or 911: Note the time when any of the symptoms first appear.
Alternatively, the acronym BE FAST can be used, with 'B' standing for 'Balance' and 'E' for 'Eyes'.

Stroke treatment: clot-busting medication, thrombectomy, stent insertion, etc
Stroke is a brain attack that requires immediate medical attention. It can strike anyone at any age, regardless of risk factors such as age, gender, or family history. However, certain underlying conditions, such as diabetes, high blood pressure, high cholesterol, and smoking, can increase the likelihood of having a stroke.
When it comes to stroke treatment, several options are available, including clot-busting medication, thrombectomy, and stent insertion. Here is an overview of these treatment methods:
Clot-Busting Medication
Clot-busting medications are used to treat ischemic strokes caused by blood clots blocking blood flow to the brain. The standard clot-busting medication is called alteplase (tPA), which is administered through an initial injection followed by an hour-long infusion. A newer medication, tenecteplase, is given as a single injection into the bloodstream and has been found to be safer and more effective, simplifying stroke treatment in specialized ambulances called mobile stroke units.
Thrombectomy
A thrombectomy is a procedure where a mechanical device, such as a stent retriever, is used to remove a blood clot from a blood vessel in the brain. This procedure is often performed by neurointerventional surgeons or interventional neuroradiologists. By inserting a catheter into an artery, usually in the groin, they can navigate it through the blood vessels to the site of the clot. The stent retriever is then deployed to capture and remove the clot, restoring blood flow to the affected area of the brain.
Stent Insertion
Stent insertion, or stent placement, is a procedure used to treat intracranial stenosis (narrowing of brain blood vessels) and brain aneurysms. Intracranial stenosis is often caused by atherosclerosis, which leads to the buildup of fat and other substances (plaques) in the blood vessels. Stents are small, mesh-like tubes made of metal, typically nitinol (nickel-titanium alloy). They are inserted into the narrowed or blocked blood vessels in the brain to open them and improve blood flow.
Stent placement for intracranial stenosis is recommended for patients experiencing severe symptoms, defined as 70% blockage or more, who have not responded to medical treatment with aspirin and blood thinners. For brain aneurysms, stents are used in conjunction with detachable coils to block the aneurysm from circulation and stabilize the artery.
In conclusion, stroke treatment has advanced with the development of new clot-busting medications, improvements in thrombectomy techniques, and the utilization of stent insertion for specific conditions. These treatments aim to restore blood flow to the brain, reduce the risk of permanent damage, and improve patient outcomes.

Stroke prevention: regular check-ups, healthy weight, exercise, quitting smoking, etc
Stroke is a serious medical condition that can affect anyone, regardless of age. While factors like age, gender, and family history are non-modifiable risk factors, there are several preventative measures one can take to lower the risk of experiencing a stroke. Here are some essential strategies for stroke prevention:
Regular Check-ups
It is crucial to schedule regular appointments with your physician to monitor your health and identify any potential risk factors for stroke. During these check-ups, your doctor can assess your blood pressure, cholesterol levels, and blood sugar levels, which are all important indicators of stroke risk. High blood pressure, in particular, is a significant factor in stroke risk, and regular check-ups can help ensure it is controlled.
Maintain a Healthy Weight
Maintaining a healthy weight is essential for stroke prevention. Being overweight or obese increases your risk of stroke. Calculate your Body Mass Index (BMI) or consult your doctor to determine if your weight is within a healthy range. Losing weight safely and sustainably can help manage other risk factors, such as high blood pressure, high cholesterol, and diabetes, which are all associated with a higher risk of stroke.
Exercise Regularly
Engaging in regular physical activity is a powerful way to reduce your stroke risk. Aim for at least 30 minutes of moderate-intensity exercise, such as a brisk walk, on most days of the week. Physical activity helps maintain a healthy weight and can lower your cholesterol and blood pressure levels, reducing the strain on your heart and improving your overall cardiovascular health.
Quit Smoking
If you smoke, quitting is one of the most effective ways to lower your stroke risk. Smoking significantly increases your chances of having a stroke, as it thickens the blood, raises blood pressure, and affects cholesterol levels. Quitting smoking can improve your health rapidly; within just eight hours of quitting, the level of oxygen in your blood returns to normal, and carbon monoxide and nicotine levels in your blood decrease by half. After one year of quitting, your risk of stroke is halved compared to a smoker.
Healthy Diet
Adopting a healthy diet is an important component of stroke prevention. Choose foods low in saturated fats, trans fats, and cholesterol, and incorporate plenty of fresh fruits and vegetables. Limiting salt (sodium) in your diet can also help lower blood pressure, which is a significant risk factor for stroke.
