A stroke, often referred to as a brain attack, occurs when blood supply to the brain is suddenly interrupted. This deprivation of oxygen and nutrients can lead to rapid brain cell death, resulting in various neurological deficits.

Types of Brain Stroke
There are two primary types of Brain stroke:
1. Ishemic Stroke
2. Hemorrhagic Stroke
Brain Stroke Causes..
Several factors can increase the risk of Brain stroke:
High Blood Pressure: A major risk factor.
Heart Disease: Conditions like atrial fibrillation can increase the risk.
High Cholesterol: Can contribute to plaque buildup in arteries.
Diabetes: Uncontrolled diabetes can damage blood vessels.
Smoking: Increases the risk of blood clots.
Excessive Alcohol Consumption: Can damage the heart and blood vessels.
Brain Stroke Symptoms
Recognizing the signs of a Brain stroke is crucial for timely intervention. The acronym FAST can help:
Face: Is one side of the face drooping?
Arms: Can the person raise both arms?
Speech: Is speech slurred or difficult to understand?
Time: Time is critical. Call emergency services immediately.
Ischemic Stroke
What is Ischemic Stroke?
An ischemic stroke occurs when a blood clot blocks a blood vessel in the brain. This blockage deprives brain tissue of oxygen and nutrients, leading to cell death.
Causes of Ischemic Stroke:
Atherosclerosis: A buildup of plaque in the arteries, which can narrow the blood vessels and increase the risk of clots.
Atrial fibrillation: An irregular heart rhythm that can cause blood clots to form in the heart and travel to the brain.
High blood pressure
Diabetes
Smoking
High cholesterol
Symptoms of Ischemic Stroke:
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body
Sudden confusion, trouble speaking, or difficulty understanding speech
Sudden trouble seeing in one or both eyes
Sudden severe headache with no known cause
Sudden dizziness or loss of balance
Diagnosis of Ischemic Stroke:
To diagnose an ischemic stroke, healthcare providers may use various tests:
CT Scan: To identify bleeding in the brain.
MRI Scan: To assess brain damage and blood flow.
Blood Tests: To check for clotting disorders and other risk factors.
Carotid Ultrasound: To check for narrowing of the carotid arteries in the neck.
Hemorrhagic Stroke
A hemorrhagic stroke occurs when a blood vessel in the brain ruptures and bleeds. This bleeding can damage brain tissue and lead to severe neurological deficits.
Causes of Hemorrhagic Stroke:
High Blood Pressure: This is a major risk factor for hemorrhagic stroke.
Aneurysm: A weak spot in a blood vessel that can rupture.
Arteriovenous Malformation (AVM):A tangle of blood vessels in the brain.
Head Injury: Trauma to the head can cause bleeding in the brain.
Blood Clotting Disorders: Certain conditions can make it easier for blood to clot and rupture blood vessels.
Symptoms of Hemorrhagic Stroke
Sudden, severe headache: Often described as the “worst headache of your life.
Sudden, severe vomiting
Sudden difficulty speaking or understanding speech
Sudden weakness or numbness in the face, arm, or leg
Sudden vision problems
Seizures
Diagnosis of Hemorrhagic Stroke
CT Scan:This imaging test can quickly identify bleeding in the brain.
MRI Scan:This test can provide more detailed images of the brain.
Lumbar Puncture: This procedure involves removing a sample of cerebrospinal fluid to check for blood.
Angiography: This test uses X-rays to visualize blood vessels in the brain.
