Stroke

Why does a stroke happen?

A stroke is a potentially life-threatening condition caused when the blood supply to your brain is interrupted. The interruption deprives your brain of vital oxygen.

The most common cause of a stroke is a clot lodged in one of your major arteries. This kind of stroke is called an ischemic stroke. Ischemic strokes account for about 90% of all strokes. 

Less often, a blood vessel ruptures in your brain and bleeds, causing what’s known as a hemorrhagic stroke. Both forms of stroke can cause temporary or permanent impairment of your speech, thoughts, and movements, depending on the location of the stroke. Some strokes are severe enough to cause death.

Is a transient ischemic attack a stroke?

A transient ischemic attack (TIA) is sometimes called a mini-stroke. This form of stroke results from a blocked artery, and often goes away without treatment. 

Although brief, a TIA typically signals an underlying serious medical condition that improves without medical help. Even if your TIA goes away, contact Advanced Center for Neurology and Headache for a full health assessment.

How do I know if I had a stroke?

The acronym FAST helps you identify the signs of a stroke so you can take appropriate action:

• Facial drooping, usually on one side
  
• Arm or other limb weakness
  
• Speech difficulty
  
• Time to call 911

Other stroke symptoms include numbness or paralysis in your legs or arms. 

Who is at risk for a stroke?

Certain risk factors increase your likelihood of having a stroke, such as:

• High blood pressure
  
• High cholesterol
  
• Older age
  
• Heart disease
  
• Atrial fibrillation
  
• Family history of a stroke or TIA

You’re at higher risk if you’ve had a TIA before.

Can I be screened for a stroke?

If you have any of these risk factors, the team at Advanced Center for Neurology and Headache recommends a stroke screening. The screening includes a Doppler ultrasound of your carotid arteries to look for signs of narrowing or blockage that may heighten your risk of having a stroke. If you’re at risk, your provider works with you to manage your risk factors to lower your chances of having a stroke.
