- Ischemic strokes require clot-dissolving drugs or mechanical clot removal; hemorrhagic strokes may need surgery to stop bleeding in the brain.
- The first 4.5 hours after a stroke are critical; treatment given within this window dramatically improves recovery.
- This blog explains emergency treatment options, recovery stages, and how to prevent a second stroke.
India records nearly 1.8 million strokes every year, making it the leading cause of adult disability in the country, according to data published by the Indian Stroke Association. Stroke is a medical emergency with no equal and during every minute without treatment, approximately two million brain cells die permanently.
Stroke treatment outcomes are almost entirely determined by how quickly the patient reaches a hospital equipped to provide emergency stroke care. Understanding the warning signs, the treatment options, and what happens in the hospital gives patients and families the knowledge to act in the minutes that matter most.
What Is a Stroke?
A stroke occurs when the blood supply to part of the brain is interrupted, either because a clot blocks an artery (ischemic stroke) or because a blood vessel ruptures and bleeds into or around the brain (haemorrhagic stroke). Without a continuous blood supply, brain cells begin dying within minutes.
The two types require completely different treatments. Giving the wrong treatment can cause serious harm, which is why every stroke patient must reach a hospital for an emergency brain scan before any treatment is administered.
A Transient Ischaemic Attack (TIA), sometimes called a mini stroke, produces identical symptoms to a full stroke but resolves within 24 hours as the clot dissolves on its own. A TIA is a serious warning sign that a full stroke may be imminent. Patients who experience TIA symptoms should go to the emergency department immediately even if they feel better, as the risk of a full stroke in the days following a TIA is high.
Recognising a Stroke: Act FAST
The FAST acronym is the most important stroke awareness tool available to the public:
- F (Face): Is one side of the face drooping? Ask the person to smile. An uneven smile is a warning sign.
- A (Arms): Can the person raise both arms? One arm drifting downward when both are raised indicates arm weakness.
- S (Speech): Is the person’s speech slurred, confused, or impossible to understand?
- T (Time): Call 108 immediately if any of these signs are present.
Additional warning signs include a sudden severe headache described as the worst headache of the person’s life, sudden loss of vision in one or both eyes, sudden loss of balance or coordination, and sudden confusion or difficulty understanding speech. None of these symptoms should be observed and waited on. Every minute between symptom onset and treatment worsens the outcome.
Ischemic Stroke: Causes and Treatment
Ischemic stroke accounts for approximately 85 percent of all strokes. It occurs when a blood clot, either formed in the brain’s arteries or travelling from the heart or another blood vessel, blocks an artery supplying the brain.
IV tPA (Clot-Dissolving Drug)
The primary ischemic stroke treatment is intravenous tPA (tissue plasminogen activator), a clot-dissolving drug that must be administered within 4.5 hours of the onset of the symptom/s. When given within this window, tPA dissolves the clot and restores blood flow to the affected area of the brain, significantly reducing the extent of permanent damage.
The 4.5-hour window is the most critical factor in ischemic stroke outcomes. Patients who arrive at a stroke-capable hospital within two hours of symptom onset have the best prospects for tPA treatment and meaningful recovery.
Mechanical Thrombectomy
For large vessel occlusions where the clot is too large for tPA to dissolve effectively, or for patients who arrive after the tPA window has closed, mechanical thrombectomy is the primary treatment. A catheter is guided through the blood vessels to the site of the clot, which is captured and removed mechanically under real-time imaging guidance.
Mechanical thrombectomy has been shown to be effective up to 24 hours after symptom onset in carefully selected patients with imaging evidence that viable brain tissue remains to be saved. After successful treatment, blood thinners are prescribed to prevent recurrence. Coronary angiography and neurovascular imaging use the same catheter-based principles, and hospitals with established interventional cardiology programmes typically have the imaging infrastructure required to support stroke thrombectomy.
Haemorrhagic Stroke: Causes and Treatment
Haemorrhagic stroke accounts for approximately 15 percent of strokes, but causes a disproportionate share of stroke deaths. It occurs when a blood vessel in or around the brain ruptures, causing bleeding that compresses brain tissue and raises intracranial pressure.
The most common causes are uncontrolled high blood pressure that weakens vessel walls over time, a ruptured cerebral aneurysm, and arteriovenous malformation (AVM) which is an abnormal tangle of blood vessels present from birth. Hypertensive heart disease and its relationship to blood vessel damage is one of the most important reasons blood pressure control is emphasised so strongly as a stroke prevention measure.
Hemorrhagic stroke treatment focuses on:
- Controlling blood pressure to reduce ongoing bleeding pressure
- Medications to reduce brain swelling and lower intracranial pressure
- Reversal of any anticoagulant drugs if the patient was taking blood thinners
- Surgical intervention in severe cases to stop the bleeding or clip an aneurysm
tPA clot-dissolving drugs are absolutely contraindicated in haemorrhagic stroke. Giving tPA to a patient with a haemorrhagic stroke worsens the bleeding and is potentially fatal. This is why the emergency brain scan before any stroke treatment is given is non-negotiable.
What Happens in the Hospital?
When a stroke patient arrives at a hospital’s emergency department, the first priority is an emergency brain scan, either a CT scan or an MRI, completed within minutes of arrival. The scan determines whether the stroke is ischemic or hemorrhagic, which determines every subsequent treatment decision.
After the diagnosis is confirmed and treatment is initiated, the patient is admitted to an intensive care unit or stroke unit for continuous monitoring of blood pressure, blood glucose, oxygen levels, heart rhythm, and neurological status for 24 hours to 72 hours.
A specialised stroke unit with neurologists, physiotherapists, speech therapists, and occupational therapists working together as a coordinated team consistently produces better recovery outcomes than standard medical ward care. Before any food or water is given, a swallowing assessment is performed because stroke frequently affects the muscles involved in swallowing, creating a risk of aspiration pneumonia if feeding is started before the assessment is complete.
Stroke Recovery and Rehabilitation
Recovery after a stroke begins within 24 hours to 48 hours of medical stabilisation, as soon as the patient is safe to begin activities. Early mobilisation, including sitting up, standing, and taking first steps with support, is one of the strongest predictors of functional recovery.
The three primary components of post-stroke treatment rehabilitation include:
- Physiotherapy: It’s focused on regaining movement, strength, balance, and coordination in the affected limbs. Recovery of walking ability is the primary physiotherapy goal for most patients.
- Speech and language therapy: These address both communication difficulties and swallowing disorders. Aphasia (difficulty with language) affects a significant proportion of stroke patients and requires intensive therapy.
- Occupational therapy: This focuses on helping patients relearn the daily tasks required for independent living, including dressing, cooking, personal hygiene, and returning to work where appropriate.
Most neurological recovery occurs in the first three to six months after a stroke, but meaningful progress can continue for years with sustained rehabilitation effort. Family involvement in the rehabilitation process is consistently shown to improve outcomes. Understanding the exercises, supporting practice between therapy sessions, and facilitating a safe home environment all contribute to the patient’s recovery trajectory.
How to Prevent a Second Stroke
The risk of a second stroke is the highest in the days and weeks immediately following the first. The preventive measures with the strongest evidence are:
- Control blood pressure: A high blood pressure is the single most important modifiable risk factor for stroke. Target blood pressure below 130 over 80 mmHg with medications as prescribed.
- Take blood thinners consistently: For patients with ischemic stroke, antiplatelet drugs such as aspirin and clopidogrel, or anticoagulants for those with atrial fibrillation, are lifelong medications. Stopping them without medical advice significantly increases recurrence risk.
- Control diabetes: High blood glucose damages blood vessels over time and is a major independent stroke risk factor.
- Lower cholesterol: Statins reduce the risk of recurrent stroke in ischemic stroke patients and are prescribed routinely after the first ischemic stroke.
- Quit smoking: Smoking doubles stroke risk and accelerates the vascular damage that underlies most strokes.
- Regular neurologist follow-up: Monitoring risk factors, adjusting medications, and identifying any early signs of recurrence through follow-up imaging.
Frequently Asked Questions
Can a stroke patient fully recover?
Recovery depends on the stroke’s location, severity, and how quickly treatment was received. Mild strokes with rapid treatment often allow full or near-full functional recovery. More severe strokes may leave lasting deficits, but sustained rehabilitation over months and years consistently produces meaningful improvement beyond what is apparent in the immediate post-stroke period.
How long does stroke treatment take?
Emergency treatment with tPA takes approximately one hour. Mechanical thrombectomy takes one to three hours. Hospital admission for monitoring and initial rehabilitation typically lasts 7 days to 14 days for moderate strokes. Outpatient rehabilitation continues for months to years depending on the extent of disability and the patient’s recovery trajectory.
What is the difference between a stroke and a TIA?
A TIA produces identical symptoms to a full stroke but resolves completely within 24 hours because the clot dissolves on its own before permanent damage occurs. Despite the resolution of symptoms, a TIA is a medical emergency requiring urgent hospital assessment because the risk of a full stroke in the following days is significantly elevated.
How soon should a stroke patient reach the hospital?
The sooner the better, with no lower limit. The clot-dissolving drug tPA must be given within 4.5 hours of symptom onset. Mechanical thrombectomy is effective up to 24 hours for selected patients. Every minute of delay between symptom onset and treatment results in additional permanent brain cell death that cannot be reversed.
