A transient ischemic attack is a major precursor to stroke, so sudden changes in vision should never be ignored. Studies have shown that 43 percent of stroke patients experience mini-stroke symptoms up to a week before experiencing a full-blown ischemic attack (TIA).
This highlights the fact that patients with symptoms should be seen immediately by a doctor for evaluation, as seizures are a major precursor to a major stroke. While these symptoms rarely last longer than 24 hours, longer symptoms have been reported in some cases.
“It’s important to seek medical attention as the immediate signs and symptoms of TIA are the same,” say experts. The main difference between the symptoms is the severity of their manifestation, as stroke is caused by a more severe variant of blood flow dysfunction.
Gary Bartlett of Beversbrook Medical Center explains: “Some people who have had a stroke find that they have sudden loss of vision in one eye, sometimes without pain. Sometimes people notice a dark area or shadow covering the upper or lower half of their field of vision.”
Amaurosis Fugax is a temporary loss of vision in one eye due to a transient ischemic attack (TIA), commonly known as a mini-stroke.
Patients often describe this condition as a vertical drape over the field of vision in one eye.
The prognosis for the stroke patient is significantly worse, so not ignoring symptoms when they occur can have life-saving effects.
In fact, research shows that about one in three people who experience this condition will eventually have a stroke, and about half of these people will have the disease within a year.
While this condition usually occurs without warning, some people may experience temporary numbness, weakness, or tingling in an arm or leg, called paresthesia.
Paresthesia is used to describe abnormal sensations such as pins and needles, tingling, and pins and needles. Alternatively, it is defined as the sensation of ants crawling on/under the skin.
Symptoms such as tingling indicate that plaque buildup in the arteries is affecting the sensory nervous system.
Alternatively, a TIA patient may have problems with speech or balance.
This is because a blood clot forms in the artery, which is caused by plaque buildup.
Lowering blood pressure and cholesterol significantly reduces the risk of stroke.
The best things to help prevent strokes are to eat a healthy diet, exercise regularly, and avoid smoking and drinking too much.
These lifestyle measures can help reduce the risk of arterial occlusion and other precursors to stroke, such as atrial fibrillation.
