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.
During a TIA, 1 of the blood vessels that supply your brain with oxygen-rich blood becomes blocked. This blockage is usually caused by a blood clot that's formed elsewhere in your body and travelled to the blood vessels supplying the brain, although it can also be caused by pieces of fatty material or air bubbles.
Mini strokes resolve quickly and lead to a full recovery. However, while mini strokes themselves are not life-threatening events, they are a warning sign of a more serious stroke in the near future. Therefore, patients who experience a TIA should take immediate steps to address any stroke risk factors they may have.
In a TIA , unlike a stroke, the blockage is brief, and there is no permanent damage. The underlying cause of a TIA often is a buildup of cholesterol-containing fatty deposits called plaques (atherosclerosis) in an artery or one of its branches that supplies oxygen and nutrients to the brain.
All types of strokes — including TIAs — require immediate medical attention. Because a TIA may eventually lead to a larger stroke, diagnosis and treatment are important.
A transient ischemic attack (TIA), also called a mini stroke, is a temporary blockage of blood flow to the brain, often indicating that a larger stroke is coming.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
The good news is you absolutely can live a full life after a mini-stroke. Here's how. Like strokes, mini-strokes occur when a blockage occurs in a major artery to your brain, disrupting the flow of blood and oxygen. The difference is in a mini-stroke, the disruption lasts only minutes, so there's no permanent damage.
Because mild strokes do not typically cause major impairments, recovery is usually fast. Sometimes recovery from a mild stroke can occur within 3-6 months. Other times it can take longer. There are many variables that affect the time it takes to recover.
You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.
Trouble walking, talking or understanding. Difficulty swallowing. Weakness, tingling or numbness, typically in one side of the body. Confusion.
Aspirin and other antiplatelet medicines
You'll probably be given low-dose aspirin straight after a suspected TIA. Aspirin works as an antiplatelet medicine. Platelets are blood cells that help blood to clot. Antiplatelet medicines work by reducing the ability of platelets to stick together and form blood clots.
These areas of dead brain cells are smaller than with a traditional stroke and they impact less-functional areas of the brain, but researchers are finding that they can still have a significant and lasting impact on memory. Silent strokes are actually far more common than strokes with symptoms.
Even after surviving a stroke, you're not out of the woods, since having one makes it a lot more likely that you'll have another. In fact, of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.
Some people might have more than one TIA and it is possible to have several TIAs in a short space of time (for example, several TIAs within a day).
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.
Conclusions. Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of incident stroke or TIA in middle-aged and older adults.
Blood tests for stroke. There is no blood test that can diagnose a stroke. However, in the hospital, your doctor or nurse may do a series of blood tests to learn the cause of your stroke symptoms: Complete blood count (CBC).
Weakness or numbness of the face, arm or leg, usually on one side of the body. Trouble speaking or understanding. Problems with vision, such as dimness or loss of vision in one or both eyes. Dizziness or problems with balance or coordination.
The blockage in the blood vessels responsible for most TIAs is usually caused by a blood clot that's formed elsewhere in your body and travelled to the blood vessels supplying the brain. It can also be caused by pieces of fatty material or air bubbles.
If the person researches what causes mini-strokes, they will discover that 90 percent are caused by plaque-filled blood vessels blocking the blood flow to the brain or by a blood clot that travels from other parts of your body — like the heart — to the brain. The above mentioned can be caused by: Smoking.

You must stop driving for at least 1 month after a transient ischaemic attack ( TIA ) or mini-stroke. This includes amaurosis fugax or retinal artery fugax. You can restart only when your doctor tells you it is safe.
