Understanding Ischemic Stroke: Act Fast, Save Lives

An ischemic stroke is a serious but treatable condition caused by a blocked artery in the brain. This guide explains what happens during a stroke, how to spot the warning signs using “BE FAST”, and the life-saving treatments available—in simple, easy-to-understand terms.

What is an Ischemic Stroke?

An ischemic stroke occurs when a blood clot blocks an artery supplying blood to the brain. Without prompt treatment, this blockage can cause lasting brain damage. Time is critical—recognizing the signs and acting fast can save lives.

Know the Warning Signs: Brain Aneurysm Symptoms

Brain aneurysms can be silent—until they’re not. Whether ruptured (a life-threatening emergency) or unruptured (often symptom-free but sometimes noticeable), recognizing the signs early can make all the difference.

Ruptured Aneurysms

When an aneurysm ruptures, the symptoms are sudden and severe. The most unmistakable sign is an explosive headache – often described as the worst pain imaginable. You may develop a rigid, painfully stiff neck, unbearable light sensitivity, and violent nausea with vomiting. Some people suddenly lose consciousness, experience seizures, or become profoundly confused. This is a critical brain emergency requiring immediate medical attention – call emergency services without delay. While terrifying, prompt treatment offers the best chance for recovery.

Unruptured Aneurysms

Unruptured brain aneurysms are typically discovered during routine scans for other health issues. Most cause no symptoms at all, but larger ones pressing on nerves may lead to noticeable warning signs like a drooping eyelid, persistent headaches, eye discomfort, blurred vision, or facial numbness. While this diagnosis can feel unsettling initially, today’s medical advances provide reliable monitoring and effective treatment options. If you experience any of these symptoms—especially if they appear suddenly—contact your doctor right away for proper evaluation and guidance.

How Doctors Diagnose Brain Aneurysms?

Doctors use three main scans to check for aneurysms:

  • CT Scan/CT Angiogram – A quick scan using X-rays to spot bleeding and show blood vessels.
  • MRI/MRA – Uses magnets (no radiation) for detailed pictures of aneurysms.
  • Cerebral Angiography – A thin tube is guided to your brain vessels for the clearest images.
All tests are done while you lie comfortably, and take about 30-60 minutes. Your doctor will recommend which is best for your situation.

Understanding Brain Aneurysm Treatment Options

If you or a loved one has been diagnosed with a brain aneurysm, knowing your treatment options can help ease concerns. Today, doctors have effective ways to treat aneurysms, ranging from traditional surgery to minimally invasive procedures. The right approach depends on your specific condition, and your medical team will recommend what’s best for you.

Surgical Clipping Option

A neurosurgeon gently places a tiny metal clip on the aneurysm’s neck to stop blood flow to it. This requires a small opening in the skull but provides a long-term solution.

Minimally Invasive Options

Doctors can often treat aneurysms without major surgery by using a thin catheter (inserted through the wrist or groin):

  • Coiling: Soft platinum coils are placed inside the aneurysm to seal it off.
  • Flow Diverters: A small stent redirects blood flow away from the aneurysm, allowing it to heal naturally over time.
