Some changes in vision may indicate the development of a transient ischemic attack (TIA), which often occurs before the onset of a “classic” stroke, experts from the Mayo Clinic reminded.

A stroke is a life-threatening damage to the brain due to disruption of its blood supply. It is believed that this pathology has a sudden nature, but doctors have stated: sometimes vision problems warn of the onset of a stroke – they can occur a few days or weeks before a stroke.

According to doctors from the Mayo Clinic, such problems with vision can occur due to the development of a transient ischemic attack (TIA), which almost half of its victims suffer before the actual stroke.

“Studies have shown that up to 43 percent of stroke patients experience symptoms of a mini-stroke in the week before it or TIA,” experts said.

During the development of TIA, which doctors call the main precursor of a major stroke, such changes as vision may occur.

• There is a sudden loss of vision in one eye, there may be discomfort or pain in the other eye.
• The upper or lower half of the field of vision suddenly darkens.

“Patients with a mini-stroke often describe a disturbance that reminds them of a curtain that closes the field vision in one eye,” experts said.

Other TIA symptoms. Some people may experience temporary numbness, weakness, or tingling in one arm or leg, known as paresthesia. p>

Be sure to see a doctor! Sudden vision problems are a warning sign that may be associated with a stroke, health professionals say. If you suspect a mini-stroke, you should definitely consult a doctor and be examined. According to the Mayo Clinic, approximately one in three people who have had a mini-stroke will develop a full stroke within a few months.
