Description

Transient Ischemic Attack (TIA) is a prognostic indicator of stroke, with one-third of untreated TIA patients having a stroke within five years. About 1 in 10 TIA patients will have a stroke in the next 3 months. The interval from the last TIA is an important predictor of stroke risk. Of all patients who later had a stroke, 21% will have a stroke within a month and 51% will have a stroke within a year. In one series, TIA patients had a 3- month stroke risk of 10.5%, as well as a post-stroke recurrence rate. In addition, 50% occurred within 48 hours of the onset of TIA. Cardiac events are the leading cause of death in patients with TIA. The annual mortality rate after TIA is 5%-6%, mainly due to MI.

TIA is a sudden, transient "non-progressive" neurological deficiency. Due to localized ischemia of the brain, retina, or cochlea; it takes less than 24 hours. Most TIA takes only a few minutes. Episodes that last more than an hour are usually due to a small infarct. The time-based definition of TIA is inadequate, as the advent of Diffusion-Weighted Magnetic Resonance Imaging (DW-MRI) often reveals infarcts on DW-MRI of patients whose clinical symptoms have completely disappeared within hours. Therefore, a "tissue-based" modification of the TIA definition is proposed to include all transient episodes, regardless of duration, associated with clinically relevant imaging lesions defined as stroke. Patients with TIA and DWMRI lesions have an increased early risk of subsequent stroke than patients without lesions. The ABCD2 score is a risk stratification score for TIA patients based on age, blood pressure (≥ 140/90 mm Hg), clinical features, TIA duration, and diabetes.

From head to toe, our blood carries oxygen to every part of the body. Blocking blood flow somewhere can cause major problems. The serious consequences are transient ischemic attacks, or problems called TIA for short.

With TIA, blood flow to parts of the brain is blocked for a short time it is also called a mini stroke. The TIA may indicate that that a full-blown stroke is imminent. About one in three people with TIA often have a stroke within a year.

TIA is short and does not cause permanent damage, but it is important to treat it like an emergency and receive immediate treatment. TIA is very similar to ischemic stroke, which is also caused by blood clots.

The main difference is that TIA only takes a few minutes. The blood clots are then pushed out, like a temporary blockage of a pipe, or chemicals in the body quickly break down the blood clots. Normal blood flow returns to the brain before permanent problems occur. Symptoms can last up to 24 hours, but usually disappear within an hour.

Strokes, on the other hand, do not go away immediately. That is, a part of the brain is deficient in oxygen, and the longer it lasts, the more damage it causes. While TIA occurs, resolves, and remains symptom-free, stroke can have long-term consequences and can be life-threatening.

Plaque can reduce blood flow through arteries and form blood clots. Blood clots that move to other parts of the body, most commonly the arteries that supply the blood to the brain, can also cause TIA. In the early stages of TIA, it is not possible to determine whether we have a TIA or a full-blown stroke.

The risk of stroke is highest in the first 3 months after TIA, especially in the first month. TIA is generally occur in people with atherosclerosis or coronary artery disease. In fact people with TIA, are even more likely to die of a heart attack than a stroke.

The TIA is a warning sign that we may be at risk of a full-blown stroke in the near future. The test helps the doctor determine the best way to reduce the likelihood of such an event. If we may have TIA in the past, but our symptoms have disappeared and we have not seen a doctor at that time, make an urgent appointment with the doctor. They can decide if we should be referred to a hospital visit. Most types of chemotherapy-related pain improve or disappear between treatments. However, nerve damage often worsens with each dose. We need to stop medication becuase it may cause the nerve damage. It can take months or years for chemotherapy-induced nerve damage to improve or disappear. For some people, it can cause permanent damage.
