A stroke happens when blood flow to part of the brain is interrupted or when a blood vessel in the brain ruptures and causes bleeding. Because brain tissue can be damaged rapidly, suspected stroke requires immediate medical evaluation and treatment.
Dr. Debasish Hota provides neurological and neurointerventional care for patients with stroke and related cerebrovascular conditions. Treatment is individualized according to the type of stroke, severity, timing of symptoms, imaging findings, underlying cause, and overall health. Depending on the patient’s condition, treatment may include medical management, thrombolysis, mechanical thrombectomy, or other appropriate neurovascular interventions.
If you suspect a stroke, seek emergency medical attention immediately.
A stroke is a serious neurological condition caused by a disruption in blood supply to part of the brain. The brain needs a continuous supply of oxygen and nutrients, and when blood flow is interrupted, brain cells can start to die within minutes. The effects of a stroke – and how much of the body it affects – depend on which part of the brain is involved and how much tissue is damaged.
There are two main types of stroke: ischemic stroke and hemorrhagic stroke.
An ischemic stroke occurs when a blood vessel supplying the brain becomes blocked, usually by a blood clot. This is the most common type of stroke. Depending on the timing, the location of the blockage and imaging findings, treatment may include clot-dissolving medication or, for selected patients, referral for a neurointerventional clot-retrieval procedure.
A hemorrhagic stroke occurs when a blood vessel in or around the brain ruptures, causing bleeding. Treatment depends on the location and amount of bleeding, its underlying cause, the patient’s blood pressure and neurological condition. Management may involve blood pressure control, medication, close neurological monitoring, and, in selected cases, neurosurgical or neurointerventional treatment.
A transient ischemic attack, or TIA – sometimes called a “mini stroke” – causes temporary stroke-like symptoms when blood flow to part of the brain is briefly interrupted. Even if the symptoms go away on their own, a TIA should never be ignored. It can be an early warning sign of a future stroke and needs prompt medical evaluation to find the cause and start preventive treatment.
Stroke symptoms usually appear suddenly. A simple way to remember the warning signs is BE-FAST:
Other warning signs include sudden confusion, sudden severe headache (especially with other neurological symptoms), and sudden dizziness. These symptoms can appear in adults of any age, including younger adults, so age alone should never rule out the possibility of a stroke.
If you notice any BE-FAST signs in yourself or someone else:
Some stroke treatments only work within a limited time window from when symptoms begin, so getting to a hospital quickly gives the medical team the best chance to evaluate treatment options.
Stroke should always be treated as a medical emergency when
neurological symptoms appear – sudden facial weakness, arm or leg weakness, speech difficulty, vision changes, loss of balance, confusion, or a sudden severe headache with other neurological symptoms. The treatment options available depend on the type of stroke, the time since symptoms began, brain and blood-vessel imaging, and the patient’s overall medical condition.
Stroke can result from several underlying causes and risk factors, including:
Identifying the underlying cause of a stroke is an important part of both treatment and preventing another stroke.
Timely, accurate diagnosis is essential for choosing the right treatment.
A neurological assessment evaluates muscle strength, sensation, speech, vision, coordination, balance and consciousness.
A CT scan of the brain helps identify bleeding and other abnormalities and is commonly used during the initial evaluation of a suspected acute stroke. An MRI can provide more detailed images of brain tissue and help identify areas affected by reduced blood flow.
Blood-vessel imaging, such as CT angiography or MR angiography, can help identify blockages or narrowing in the arteries supplying the brain. Depending on the suspected cause, additional tests such as blood work, an ECG or echocardiography may also be recommended. Not every patient needs every test – investigations are chosen based on the individual clinical situation.
Because some stroke treatments are time-sensitive, rapid assessment and imaging help the medical team determine which time-dependent treatments may be appropriate for a given patient. This is why acting quickly on stroke warning signs matters as much as the treatment itself.
Recovery after a stroke varies from person to person and depends on the area of the brain affected, the severity of the stroke, how quickly treatment was started, and any existing medical conditions.
Depending on individual needs, post-stroke care may involve:
There is no single recovery timeline after a stroke – rehabilitation and follow-up are planned around each patient’s specific needs. Some stroke survivors also experience longer-term changes in memory or thinking; when this is connected to reduced blood flow to the brain, it is sometimes described as vascular dementia – you can read more about this on the Dementia page. Seizures can also occur after a stroke in some patients; more on this is covered on the Epilepsy page.
Not every stroke can be prevented, but managing known risk factors can meaningfully reduce the likelihood of a stroke – or a second one. Depending on individual health needs, this may include:
For patients who have already had a stroke or a TIA, an individualised prevention plan is an important part of long-term neurological care.
A specialist evaluation may be appropriate for people with:
Important: If someone is experiencing sudden symptoms of a possible stroke, do not wait for a routine appointment – seek emergency medical care immediately.
The cost of stroke treatment varies depending on the diagnosis and the treatment required. Factors that can influence overall cost include the type of stroke, diagnostic imaging, emergency treatment, hospitalisation, ICU care (when required), medication, thrombolysis (when appropriate), any procedure required, and follow-up or rehabilitation care. Because stroke treatment is highly individualised, an accurate estimate can only be given after a medical evaluation. Contact the clinic to discuss consultation and treatment-related questions.
The outcome following stroke varies significantly between patients.
Recovery can depend on:
Some patients may experience significant improvement, while others may require longer-term medical support and rehabilitation.
The focus of treatment is to address the acute stroke, prevent further neurological injury where possible, manage the underlying cause and support recovery.
Yes. A suspected stroke requires immediate medical evaluation because some treatments are time-sensitive. Do not wait for symptoms to improve on their own.
Stroke diagnosis may involve a neurological examination, CT or MRI brain imaging, and blood-vessel imaging such as CT angiography when required.
Mechanical thrombectomy is a minimally invasive procedure used to remove a blood clot from a blocked brain artery in selected patients with acute ischemic stroke.
Recovery varies from person to person depending on the type and severity of stroke, the area of the brain affected, treatment timing, and rehabilitation needs. There is no single recovery timeline for every patient.
A stroke occurs when blood flow to part of the brain is blocked or when a blood vessel in the brain ruptures and bleeds, damaging brain tissue.
Common warning signs include sudden facial drooping, arm or leg weakness, slurred speech, vision changes, loss of balance and sudden severe headache. Remembering BE-FAST can help you recognise these signs quickly.
An ischemic stroke is caused by a blocked blood vessel, while a hemorrhagic stroke is caused by a ruptured blood vessel that bleeds into or around the brain. Treatment differs for each type.
A TIA, or mini stroke, causes temporary stroke-like symptoms that resolve on their own. It should still be treated seriously, as it can signal a higher risk of a future stroke.
Thrombolysis is the use of clot-dissolving medication, given through a vein, to help restore blood flow in selected patients with acute ischemic stroke.
Recovery time varies widely between patients and depends on the severity of the stroke, the area of the brain affected, and the rehabilitation plan. There is no single fixed timeline.
