Ischemic vs. Hemorrhagic Stroke: Key Differences, Causes & Advanced Treatments Explained
A stroke—commonly described as a “brain attack”—is a critical medical emergency caused by disrupted blood flow to the brain. Without oxygen and nutrients, brain cells begin to die within minutes. Prompt recognition and treatment are crucial to reducing brain damage and improving recovery. Understanding the types of strokes—particularly ischemic and hemorrhagic strokes—is vital for effective care, as each has distinct causes and treatment protocols.
Dr. Raveesh Sunkara, one of the best neurosurgeons in Hyderabad, specializes in advanced stroke management, offering cutting-edge treatments and compassionate post-stroke recovery at Arete Hospitals.
Main Types of Stroke
Strokes are categorized into:
-
Ischemic Stroke – Caused by a blood clot or blockage in brain arteries; accounts for 85% of all strokes.
-
Hemorrhagic Stroke – Caused by a ruptured blood vessel leading to bleeding in or around the brain.
-
Transient Ischemic Attack (TIA) – A temporary blockage, often a warning sign for a future stroke.
Ischemic Stroke Types
-
Thrombotic – Clot forms in a brain artery.
-
Embolic – Clot travels from another part of the body.
-
Lacunar – Blockage in small deep brain vessels.
Hemorrhagic Stroke Causes
-
High blood pressure
-
Aneurysms
-
AVMs (Arteriovenous Malformations)
-
Head injuries
Clinical & Treatment Differences
-
Ischemic Stroke: Treated with clot-busting medications like tPA or thrombectomy.
-
Hemorrhagic Stroke: Managed with blood pressure control, surgery, or coiling/clipping procedures to stop bleeding.

FAQs:
1. What is the main difference between ischemic and hemorrhagic stroke?
Ischemic strokes are caused by a blockage in a blood vessel supplying the brain, while hemorrhagic strokes result from a ruptured blood vessel causing bleeding in or around the brain.
2. What symptoms should I watch out for in a stroke?
Sudden numbness or weakness (especially on one side), confusion, trouble speaking, blurred vision, dizziness, or a severe headache may indicate a stroke. Seek emergency care immediately.
3. How is a stroke diagnosed?
Doctors typically use brain imaging like CT scans or MRIs to determine whether the stroke is ischemic or hemorrhagic and to decide the appropriate treatment.
4. What are the risk factors for a hemorrhagic stroke?
High blood pressure, aneurysms, arteriovenous malformations (AVMs), and head injuries are major risk factors.
5. Can stroke be prevented?
Yes. Managing blood pressure, avoiding smoking, staying active, and maintaining a healthy diet can significantly reduce the risk of both ischemic and hemorrhagic strokes.
