Brain Stroke: Everything You Need to Know

In the medical world, there is a saying: "Time is Brain." During a stroke, every second that the brain is deprived of oxygen results in the death of millions of neurons. Understanding the symptoms, causes, and the latest treatment options isn't just medical knowledge—it is life-saving information.

Dr. Rohit Agarwal, Interventional Radiologist at Medanta Lucknow, provides a comprehensive overview of brain stroke and explains why modern "no-cut" procedures are the gold standard for recovery.

The Two Faces of Stroke

Not all strokes are the same. Understanding the type of stroke is the first step in determining the right treatment:

• Ischemic Stroke (The Blockage): The most common type (approx. 85%). It occurs when a blood clot blocks an artery supplying the brain. This is often treated by physically removing the clot.
• Hemorrhagic Stroke (The Rupture): Occurs when a weakened blood vessel ruptures and bleeds into the brain. This causes pressure buildup and requires specialized neuro-vascular care.

Are You at Risk? Common Causes

While a stroke can happen to anyone, certain factors significantly increase your risk:

• Hypertension (High BP): The #1 cause of stroke worldwide. It weakens arteries over time.
• Diabetes: High sugar levels damage blood vessels and make clot formation more likely.
• Smoking & Lifestyle: Smoking damages the vessel lining, while a sedentary lifestyle leads to high cholesterol and plaque buildup.

Modern Treatment: Beyond Traditional Surgery

Gone are the days when major brain surgery was the only option. Today, Interventional Radiology allows us to treat strokes through a tiny pinhole in the groin or wrist:

• Mechanical Thrombectomy: For Ischemic strokes, we use a specialized device to "grab" the clot and pull it out, restoring blood flow instantly.
• Aneurysm Coiling: For Hemorrhagic strokes caused by aneurysms, we can fill the "bulge" with microscopic coils to prevent further bleeding—all without opening the skull.

The FAST Reminder

Always remember the FAST formula to identify a stroke: Face drooping, Arm weakness, Speech difficulty, and Time to call for help. If you suspect a stroke, do not wait for the morning. Rush to an advanced neuro-center immediately.
