Stroke: Causes, Symptoms, Types, Treatment, Rehabilitation and Cost in India

A stroke is a medical emergency in which blood flow to part of the brain is suddenly interrupted, causing brain cells to die within minutes. According to the World Health Organization, stroke is one of the leading causes of death and long-term disability worldwide, and the burden is growing fastest in low- and middle-income countries, including much of Africa, the Middle East and South Asia, where stroke often strikes people at a younger age. The good news is that most strokes are preventable, emergency treatments can dramatically reduce disability when given quickly, and dedicated rehabilitation helps many survivors regain independence. Leading Indian hospitals have comprehensive stroke centres, advanced neuro-interventional facilities and intensive rehabilitation programmes.

What is a Stroke?

The brain needs a constant supply of oxygen-rich blood. When that supply is cut off, the affected area of the brain stops working, leading to sudden weakness, speech problems or other symptoms depending on which part of the brain is involved.

Types of stroke

• Ischaemic stroke - the most common type, caused by a blood clot blocking an artery to the brain. The clot may form in a narrowed brain or neck artery, or travel from the heart (for example in atrial fibrillation or rheumatic heart disease).
• Haemorrhagic stroke - caused by bleeding into or around the brain. It includes intracerebral haemorrhage (usually from high blood pressure) and subarachnoid haemorrhage (often from a ruptured brain aneurysm). Arteriovenous malformations (AVMs) can also bleed.
• Transient ischaemic attack (TIA) - a "mini-stroke" with symptoms that go away, usually within minutes to hours. A TIA is a serious warning sign of a future stroke and needs urgent evaluation.

Causes and Risk Factors

• High blood pressure - the single most important risk factor for both types of stroke. It is very common and often undiagnosed in sub-Saharan Africa and South Asia, which contributes to the high rate of haemorrhagic stroke in these regions.
• Diabetes - highly prevalent in the Gulf countries and South Asia.
• Atrial fibrillation and other heart diseases, including rheumatic heart disease and artificial heart valves.
• High cholesterol, smoking, obesity and physical inactivity.
• Sickle cell disease - a major cause of stroke in children and young adults in Africa and parts of the Middle East.
• Infections such as HIV, tuberculous meningitis and infective endocarditis.
• Excessive alcohol use and drug use.
• Age, family history and previous stroke or TIA.
• Brain aneurysms and AVMs for haemorrhagic stroke.
• Pregnancy-related conditions such as pre-eclampsia, and some hormonal medicines.

Symptoms of a Stroke

Stroke symptoms appear suddenly. The easy way to remember them is BE FAST:

• B - Balance: sudden loss of balance or coordination
• E - Eyes: sudden loss of vision or double vision
• F - Face: drooping of one side of the face
• A - Arms: weakness or numbness in one arm or leg
• S - Speech: slurred speech, difficulty speaking or understanding
• T - Time: call emergency services immediately

Other symptoms include a sudden, severe headache (often described as the worst headache of one's life, typical of subarachnoid haemorrhage), confusion, vomiting, drowsiness and seizures.

Every stroke is an emergency. Do not wait to see if symptoms improve, do not give food, water or medicines by mouth, and note the time the symptoms started - this information decides which treatments are possible.

How is a Stroke Diagnosed?

• CT scan of the brain - the first test, done immediately to tell a bleed from a clot.
• CT angiography and CT perfusion - to find a blocked artery and the amount of brain that can still be saved.
• MRI brain - more sensitive for small or early strokes.
• Carotid Doppler - to check the neck arteries for narrowing.
• ECG, Holter monitoring and echocardiography - to look for atrial fibrillation and clots in the heart.
• Blood tests - blood sugar, cholesterol, clotting profile, kidney function and, in young patients, tests for clotting disorders and sickle cell disease.
• Digital subtraction angiography (DSA) - for aneurysms, AVMs and before neuro-interventional procedures.

Treatment Options for Stroke

1. Emergency treatment of ischaemic stroke

• Intravenous thrombolysis - clot-dissolving medicines such as alteplase or tenecteplase, generally given within about 4.5 hours of symptom onset in suitable patients.
• Mechanical thrombectomy - a neuro-interventionist passes a catheter from the groin or wrist to the brain and removes the clot with a stent retriever or suction device. For large artery blockages it can be performed up to 24 hours after onset in carefully selected patients, and has transformed outcomes for severe strokes.

2. Treatment of haemorrhagic stroke

• Intensive blood pressure control and reversal of blood thinners.
• Surgery to remove a large blood clot or relieve pressure on the brain (craniotomy or decompressive craniectomy), and drainage for hydrocephalus.
• Aneurysm coiling or clipping - endovascular coiling (with or without flow diverters) or surgical clipping to prevent re-bleeding.
• AVM treatment - surgery, embolisation or stereotactic radiosurgery such as CyberKnife, depending on size and location.

3. Preventing another stroke

• Antiplatelet medicines (aspirin, clopidogrel) or anticoagulants for atrial fibrillation.
• Statins, blood pressure and diabetes control.
• Carotid endarterectomy or carotid artery stenting for significant narrowing of the neck arteries.
• Closure of a patent foramen ovale (PFO) in selected young patients.

4. Rehabilitation

Rehabilitation begins as soon as the patient is stable and is the key to recovery. A team of physiotherapists, occupational therapists, speech and swallowing therapists and neuropsychologists helps patients relearn walking, hand function, speech and daily activities. Modern centres in India use robotic gait training, mirror therapy and other technologies alongside conventional therapy.

Recovery, Living After Stroke and Prevention

The fastest recovery usually happens in the first three to six months, but improvement can continue for much longer with ongoing therapy. Families play a vital role in encouraging exercises, preventing falls and watching for depression, which is common after stroke.

Most strokes can be prevented by controlling risk factors:

• Check your blood pressure regularly and keep it under control with medicines and less salt.
• Control diabetes and cholesterol.
• Stop smoking and limit alcohol.
• Exercise for at least 150 minutes a week and maintain a healthy weight.
• Eat plenty of vegetables, fruit, whole grains and fish, and fewer processed and fried foods.
• Get treatment for atrial fibrillation and take blood thinners as prescribed.
• Children with sickle cell disease should have regular transcranial Doppler screening where available.

Frequently Asked Questions

Can a stroke patient travel to India for treatment?

Emergency stroke treatment must happen at the nearest hospital, because time is critical. Once the patient is medically stable, they can travel to India for further evaluation, procedures such as carotid stenting or aneurysm treatment, and intensive rehabilitation. Your doctors will confirm fitness to fly.

How soon after a stroke can a person fly?

This depends on the type and severity of stroke and the patient's condition. Many airlines and doctors advise waiting at least 10 to 14 days after a stable stroke, and longer after a haemorrhagic stroke. A medical clearance certificate is usually required.

What is the golden hour in stroke?

It refers to the first hours after symptoms begin, when clot-busting medicines and thrombectomy are most effective. The sooner treatment starts, the more brain tissue can be saved.

Can a person fully recover from a stroke?

Many people make a good or full recovery, especially after a small stroke or when treated quickly. Others have lasting effects, but rehabilitation can greatly improve independence and quality of life.

How long is stroke rehabilitation in India?

Inpatient rehabilitation programmes usually last 2 to 6 weeks, depending on the patient's needs, followed by a home exercise programme and tele-follow-up.

What is the difference between a stroke and a heart attack?

A stroke affects blood flow to the brain, while a heart attack affects blood flow to the heart muscle. Both are emergencies and share many risk factors, such as high blood pressure, diabetes and smoking.

Can young people have a stroke?

Yes. Stroke can occur at any age, including in children with sickle cell disease or heart defects, and in young adults with high blood pressure, heart valve disease or clotting disorders.
