An MRI can sometimes show the site of the TIA, especially if it's done soon after it happens.
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.
Standard MRI images (T1 and T2) are good at detecting vasogenic edema that is present in the subacute phase of stroke and is seen at greater than 24 hours to several days.
The DWI-MRI provides not only the evidence to distinguish between TIA and acute ischemic stroke, furthermore it predicts TIA patients who are at higher risk of disabling stroke, which can be prevented by an immediate evaluation and treatment of TIA.
These brief episodes are transient ischemic attacks (TIA), sometimes called “mini-strokes.” They still should be taken seriously, because they tend to be signs of underlying serious conditions that can lead to a full stroke, even possibly in the few days following a TIA event if not evaluated and treated for a TIA.
A person experiencing a TIA might feel sudden weakness or numbness on one side of the body, have slurred speech, have trouble seeing or talking, and feel confused. The person may experience a combination of these symptoms at the same time. “The real takeaway?
An MRI can show signs of a stroke years or even decades after the stroke happens. Sometimes, a person may not know they had a stroke until a long time afterward. MRI is the most accurate way to view signs of stroke inside the brain, but a CT scan is often faster and more widely available.
Symptoms to Watch For
You likely won't know for certain that you have suffered a silent stroke without receiving a brain scan like an MRI or CT scan. After a silent stroke, a brain scan can show small white spots that indicate the presence of lesions.
A person's life expectancy after a mini stroke reduces by around 4% in the first year following the attack in comparison to people who have not had one. In the following 9 years, life expectancy reduces by 20%. These statistics come from a 2019 review .
Our study has revealed that according to neurologists, the most consistent predictors for a diagnosis of TIA include negative symptoms (loss of motor, sensory, or visual function) and speech disturbance.
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Sudden confusion, trouble speaking, or difficulty understanding speech. Sudden trouble seeing in one or both eyes. Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
Weakness, numbness or paralysis in the face, arm or leg, typically on one side of the body. Slurred or garbled speech or difficulty understanding others. Blindness in one or both eyes or double vision. Vertigo or loss of balance or coordination.
One of the most common stroke mimics is a seizure, which researchers believe account for as many as 20% of all stroke mimics. Other common stroke mimics include migraines, syncope, sepsis, brain tumor and metabolic derangement (low sodium or low blood sugar).
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
Some of the most common stroke mimics are seizures, migraine, fainting, serious infections and functional neurological disorder (FND). Once the person is diagnosed, they can have treatment or support to manage their symptoms.
Can an ECG detect stroke? Yes. ECG can detect a heart problem that might lead to a stroke or even uncover a past problem such as a previous heart attack.
Other possible symptoms
sudden vision loss, blurred vision or double vision. vertigo. being sick.
You may feel perfectly fine one minute and then suddenly develop difficulty speaking or moving one side of your body. Sometimes the symptoms will come and go several times in a short period of time.
Most people who have a mini-stroke feel fine after the event. In fact, many people don't even realize they've had one! Symptoms might include weakness, numbness, tingling, vision changes or difficulty speaking. Most symptoms are temporary and dissipate within minutes but sometimes can last up to 24 hours.
Chronic stress can indirectly cause a stroke or TIA (transient ischemic attack or mini stroke). For instance, chronic stress can lead to high blood pressure, which is a known risk factor for stroke and heart disease. Stress can also cause inflammation in the arteries all over the body.
Few patients recover fully and most are left with some disability, but the majority exhibit some degree of spontaneous recovery. Doctors and scientists don't fully understand how this happens, because the brain does not grow new cells to replace the ones damaged by the stroke.
The short answer is yes; the brain can heal after acute trauma from a stroke or brain injury, although the degree of recovery will vary. The reason the brain can recover at all is through neuroplasticity, sometimes referred to as brain plasticity.
