Can you live a normal life after a mini-stroke?

The good news is you absolutely can live a full life after a mini-stroke. Here's how.

What happens to your brain when you have a mini-stroke?

When people use the term "ministroke," what they're really often referring to is a transient ischemic attack (TIA). A TIA is a brief interruption of blood flow to part of the brain, spinal cord or retina, which may cause temporary stroke-like symptoms but does not damage brain cells or cause permanent disability.

How do doctors treat a mini-stroke?

Once your provider has determined the cause of the TIA , the goal of treatment is to correct the issue and prevent a stroke. Depending on the cause of the TIA , your provider may prescribe medication to reduce the tendency for blood to clot or may recommend surgery or a balloon procedure (angioplasty).

What are the chances of having another stroke after a mini-stroke?

Key points. Transient ischemic attack and minor stroke are highly predictive of a subsequent disabling stroke within hours or days of the first event. The risk of subsequent stroke after a transient ischemic attack is between 2% and 17% within the first 90 days after the initial event.

How do you reverse a mini-stroke?

A clot-busting medication called tPA, or tissue plasminogen activator, can be given to someone if they're having a stroke, potentially reversing or stopping symptoms from developing. But it has to be given within 4.5 hours of the start of symptoms, Dr. Humbert says.

Does memory come back after a mini-stroke?
