A stroke occurs 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 that occurs when the blood supply to part of the brain is blocked or when a blood vessel in the brain ruptures and causes bleeding.
The brain requires a continuous supply of oxygen and nutrients. When blood flow is interrupted, brain cells can become damaged. The effects of a stroke depend on which area of the brain is affected and how extensive the injury is.
There are two major types of stroke: ischemic stroke and hemorrhagic stroke. An ischemic stroke occurs when a blood vessel becomes blocked, usually by a blood clot. A hemorrhagic stroke occurs when a blood vessel ruptures and causes bleeding in or around the brain.
Stroke symptoms can appear suddenly and may include facial weakness, difficulty speaking, weakness or numbness of an arm or leg, vision changes, dizziness, loss of balance, or severe headache.
Because some stroke treatments are time-sensitive, rapid medical assessment is extremely important.
An ischemic stroke occurs when a blood vessel supplying the brain becomes blocked. The blockage reduces blood flow and oxygen delivery to brain tissue.
Depending on the timing, location of the blockage, imaging findings and other clinical factors, treatment may include medication to restore blood flow or an endovascular procedure such as mechanical thrombectomy for selected patients.
A hemorrhagic stroke occurs when a blood vessel in or around the brain ruptures and causes bleeding.
Treatment depends on the location and severity of the bleeding, its underlying cause, the patient’s neurological condition and other medical factors. Management may involve blood pressure control, medication management, close monitoring, surgery or neurointerventional treatment when appropriate.
A transient ischemic attack, or TIA, can cause temporary stroke-like symptoms when blood flow to part of the brain is briefly interrupted.
Even if symptoms disappear, a TIA should not be ignored. It can indicate an increased risk of future stroke and requires medical evaluation to identify possible causes and appropriate preventive measures.
Stroke symptoms often develop suddenly.
Common warning signs include:
Do not wait for symptoms to improve. Seek emergency medical attention immediately.
Rapid assessment can help determine whether time-sensitive stroke treatments may be appropriate.
Stroke should always be treated as a medical emergency when sudden neurological symptoms occur.
Urgent evaluation is particularly important when a person develops:
The treatment options available depend on factors such as the type of stroke, time since symptoms began, brain and blood-vessel imaging, and the patient’s overall medical condition.
For selected patients with acute ischemic stroke caused by certain large-vessel blockages, mechanical thrombectomy may be considered.
Stroke can have several causes and risk factors.
Common risk factors include:
The underlying cause of a stroke may require additional investigation.
Understanding why a stroke occurred is important for both treatment and prevention of another stroke.
Not every stroke can be prevented, but managing risk factors can help reduce the likelihood of stroke.
Depending on individual health needs, prevention may include:
Accurate and timely diagnosis is essential for determining the appropriate treatment.
A neurological assessment may evaluate:
A CT scan of the brain can help identify bleeding and other abnormalities and is commonly used during the initial evaluation of suspected acute stroke.
MRI can provide detailed images of brain tissue and may help identify areas affected by ischemia or other neurological conditions when appropriate.
Blood-vessel imaging can help identify blockages, narrowing or other abnormalities in the arteries supplying the brain.
In selected acute ischemic strokes, vascular imaging can help determine whether a large-vessel blockage is present and whether an endovascular procedure may be considered.
Depending on the suspected cause, doctors may recommend:
Not every patient requires every test. Investigations are selected according to the individual clinical situation.
Stroke treatment depends on several factors, including:
Treatment is individualized to the patient’s clinical condition.
Ischemic stroke occurs when a blood vessel supplying the brain becomes blocked.
Treatment may focus on restoring blood flow when appropriate, managing the underlying cause and reducing the risk of another stroke.
Intravenous thrombolysis involves administering clot-dissolving medication through a vein in selected patients with acute ischemic stroke.
Eligibility depends on factors such as:
A medical team must assess the patient urgently to determine whether thrombolysis is appropriate.
Mechanical thrombectomy is a minimally invasive procedure used to remove a blood clot from a blocked blood vessel supplying the brain in selected patients with acute ischemic stroke.
During the procedure, a catheter is guided through the blood vessels toward the blocked artery. Specialized devices may then be used to retrieve or remove the clot and restore blood flow.
Mechanical thrombectomy may be considered for selected patients with certain large-vessel blockages.
Assessment may take into account:
Not every patient with stroke is suitable for thrombectomy.
The procedure generally involves:
The exact technique varies according to the location of the blockage, vascular anatomy and the treating team’s assessment.
Stroke treatment can be time-sensitive. Rapid assessment and imaging allow the medical team to determine whether time-dependent treatments may be appropriate.

Hemorrhagic stroke occurs when a blood vessel ruptures and causes bleeding in or around the brain.
Treatment depends on:
Treatment may involve:
The treatment plan is individualized according to the patient’s condition and the source of the bleeding.
Neurointervention involves minimally invasive catheter-based techniques used to diagnose and treat selected conditions affecting blood vessels of the brain and neck.
Depending on the diagnosis, treatment may include:
Removal of a blood clot from a blocked brain artery in selected patients with acute ischemic stroke.
A minimally invasive procedure that may be considered for selected patients with significant narrowing of the carotid artery.
In selected cases, stenting may be considered to manage significant narrowing within an artery inside the brain.
The suitability of each procedure depends on the patient’s symptoms, diagnosis, imaging, vascular anatomy and overall clinical condition.

The medical team evaluates symptoms, medical history and neurological status.
A detailed neurological assessment helps determine the severity and possible location of the problem.
CT, MRI and/or vascular imaging may be performed depending on the suspected type of stroke.
Based on clinical and imaging findings, the medical team determines the most appropriate treatment.
This may include medical management, thrombolysis, mechanical thrombectomy, neurointerventional treatment, surgery or other supportive care.
Following acute treatment, patients may require neurological monitoring, rehabilitation, medication and follow-up care.
Stroke recovery varies from person to person.
Recovery can depend on:
Physical therapy may help address problems involving:
Some patients may experience difficulties with speech, language or swallowing and may benefit from speech and language therapy.
Occupational therapy may help patients work toward greater independence in daily activities.
Some patients experience changes in memory, attention, thinking or problem-solving following stroke. Cognitive rehabilitation may form part of the recovery plan when required.
There is no single recovery timeline for stroke. Rehabilitation and follow-up should be individualized.
After the acute phase of treatment, reducing the risk of another stroke becomes an important part of ongoing care.
Depending on the underlying cause, long-term management may include:
The prevention strategy depends on the reason the stroke occurred and the patient’s individual risk factors.
A specialist evaluation may be appropriate for patients with:
Important: If someone is experiencing sudden symptoms of an acute stroke, do not wait for a routine appointment. Seek emergency medical care immediately.
The cost of stroke treatment can vary significantly depending on the patient’s diagnosis and treatment requirements.
Factors that may influence the overall cost include:
Because stroke treatment is highly individualized, an accurate estimate can only be provided after appropriate medical evaluation and treatment planning.
Contact the clinic to discuss consultation and treatment-related information.
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.
Common warning signs include sudden weakness or numbness, facial drooping, difficulty speaking, vision problems, loss of balance, confusion, or a sudden severe headache. Seek emergency medical attention immediately if these symptoms occur.
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.
