A mini-stroke, known medically as a transient ischemic attack (TIA), occurs when there is a temporary loss of blood flow to one or more areas of the brain. This results in a brief, sudden decrease in normal function of the brain.
While a mini-stroke has the same symptoms of a full-blown stroke, typically the duration of symptoms last less than one to two hours. Not to be confused with a mild stroke, a TIA does not show up on an MRI or CT scan, but the symptoms can be easily recognized.
Recognize Symptoms
Step 1
Look for changes in sensation such as numbness, tingling and weakness. This can often be seen as stumbling, staggering, a change of gait, or a drooping of the facial features due to paralysis or a lack of coordination.
Step 2
Notice vision changes and problems, such as double vision, loss of vision in one eye, decreased vision or eye pain. This may also occur as vertigo, which is a sense of having the room move around you.
Step 3
Observe difficulty in speech, such as slurred or garbled words.
Step 4
Decide if there is abnormal weakness, usually in an arm or leg. This may be felt as a general heaviness in the limb or limbs or a loss of balance.
Step 5
Detect general confusion, such as suddenly not knowing a familiar location or what is happening around you.
Tips and Warnings
- If symptoms occur, call 911 and see a doctor immediately.
