What is a mini-stroke? Is a mini-stroke the same thing as a transient ischemic attack (TIA)?
A mini-stroke is called a transient ischemic attack, or TIA. We call these “mini-strokes” because they are less severe, but they are still a dangerous medical emergency. Without immediate treatment, TIA can have devastating effects on someone’s brain function and recovery.
Part of what makes TIAs so tricky to diagnose is that they have the same symptoms as strokes. TIA symptoms typically do not last as long as a stroke, and many people who have a TIA fail to get medical attention afterward.
Is a stroke the same thing as a TIA?
Strokes and mini-strokes are not the same thing, although they look and feel very alike. Like strokes, TIAs are characterized by muscle weakness or numbness, facial drooping, head pain, confusion, and problems with vision, speech, and balance.
However, TIA symptoms may not be as intense as stroke symptoms, and typically go away on their own. People who have a TIA are at a much higher risk of having a stroke soon after. According to the
CDC, of people who survive a TIA:
- About 13% will have a major stroke within 3 months.
- About 35% will have a major stroke within one year.
If you have any symptoms of a stroke, mild or severe,
call 911 or head to the nearest emergency room as soon as possible. Seek immediate medical attention, even if the symptoms are mild or go away.
