Symptoms
Strokes usually are classified as either ischemic or hemorrhagic. The causes of strokes and min-strokes ( transient ischemic attack, TIA) are the same, however, blood flow leakage or blockage is temporary in mini-strokes, and blood flow returns spontaneously. In most strokes, blood flow does not return spontaneously.
Causes
TIAs are most common among middle-aged and older people. TIAs differ from ischemic strokes because TIAs do not seem to cause permanent brain damage. That is, TIA symptoms resolve completely and quickly, and few or no brain cells died—at least not enough to cause any changes that can be detected by brain imaging or a neurologic examination
Prevention
Transient Ischemic Attack. In medical circles, the abbreviation TIA is used with the meaning "Transient Ischemic Attack." In this context, a TIA is a brief episode of neurological dysfunction caused by loss of blood flow to the brain, spinal cord, or retina. TIAs have the same underlying mechanism as ischemic strokes.
Complications
The symptoms of a TIA are similar to that of stroke, but they may only last a short while, certainly no more than 24 hours. If symptoms last longer than 24 hours but are mild usually this would be defined as a ‘minor stroke’. There was some confusion amongst some people we interviewed about whether they had actually had a stroke or TIA.

Will a TIA show up on an MRI?
Tests will be done to rule out a stroke or other disorders that may cause the symptoms: You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not. You may have an angiogram, CT angiogram, or MR angiogram to see which blood vessel is blocked or bleeding.

A ministroke doesn't typically lead to permanent brain damage, but you still need an urgent medical examination if you have symptoms of a ministroke. The only way to tell the difference between a ministroke and a stroke is by having a doctor look at an image of your brain with either a CT scan or an MRI scan.
How long can you live after TIA?
Results— At 1 year, 91.5% of hospitalized patients with TIA survived compared with 95.0% expected survival in the general population. After 5 years, observed survival was 13.2% lower than expected in relative terms. By 9 years, observed survival was 20% lower than expected.

What happens after a TIA?
A TIA has identical symptoms to a stroke, but these last for less than 24 hours and are followed by a full recovery.

How likely are you to have a stroke after a TIA?
The risk of stroke after transient ischemic attack is somewhere between 2% and 17% within the first 90 days. Among patients with transient ischemic attack, one in five will have a subsequent stroke (the most common outcome), a heart attack or die within one year.
