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. Plaques can decrease the blood flow through an artery or lead to the development of a clot.
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.
According to research that appeared in Stroke, an American Heart Association journal, middle-aged and older individuals with high levels of stress, depression, and hostility were subject to a significantly higher risk of stroke or TIA (Transient Ischemic Attack, commonly known as “mini-stroke”).
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.
The disruption in blood supply results in a lack of oxygen to the brain. This can cause sudden symptoms like those of a stroke. However, a TIA does not last as long as a stroke. The effects only last for a few minutes or hours and fully resolve within 24 hours.
The sooner you intervene, the better. If you ever encounter anyone experiencing mini stroke symptoms, dial 9-1-1 immediately. It is important to be evaluated as soon as possible following a mini stroke, because you may require emergency treatment in order to prevent or minimize irreversible 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.
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.
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.
An MRI scan is most often used. This type of scan uses a strong magnetic field and radio waves to create an image of your brain.
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. If you've had an ischemic stroke, it's likely that it won't show up on a CT scan of your brain for 24 to 48 hours. An MRI scan usually shows a stroke sooner.
Risk factors for TIA include family history of stroke or TIA, age above 55 years or older, higher risk of TIA in males than females, high blood pressure, diabetes mellitus, and tobacco smoking. Genetics, race, and imbalance in lipid profile are other risk factors of TIA.
How long you stay in the hospital depends on your symptoms and the treatment received. The average amount of time to stay in the hospital after a TIA is 2 to 3 days.
Following a stroke, one of the most important factors to a successful recovery is sleep. Quality sleep has many benefits, especially for stroke survivors.
If you drive a car or motorbike and you had a single transient ischemic attack (TIA) or stroke with no brain surgery or seizures, you can usually start driving again after one calendar month.
Although the symptoms of a transient ischaemic attack (TIA) resolve in a few minutes or hours without any specific treatment, you'll need treatment to help prevent another TIA or a full stroke from happening in the future. A TIA is a warning sign that you're at increased risk of having a full stroke in the near future.
“Ignoring any stroke sign could be a deadly mistake,” says Mitch Elkind, M.D., chair of the American Stroke Association. The Association recommends calling for emergency help immediately, even if the symptoms go away. Acting fast can improve your chances of accurate diagnosis, treatment and recovery.
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).
Even if a major stroke is avoided, repeated mini strokes can have a cumulative negative effect on one's brain health and cognitive function. In severe cases, vascular dementia may result from untreated cerebrovascular events.
TIAs are often an early warning sign that a person is at risk of stroke. About 1 in 3 people who has a TIA goes on to experience a subsequent stroke. The risk of stroke is especially high within 48 hours after a TIA .
You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.
