Scientists have named the main harbinger of stroke

British scientists conducted a study, according to the results of which they were able to name the main harbinger of a stroke. As it turned out, this condition is preceded by a transient ischemic attack (TIA), which is also known as “preventative stroke” and “microstroke”.

Specialists from Oxford studied the medical records of more than 2,400 people who were diagnosed with ischemic stroke. TIA attack was recorded in 549 patients. On the day of the stroke, 17% of patients suffered it, a week before the attack – 43%, and the day before it – 9% of patients. The authors of the scientific work noted that TIA lasts no more than an hour and, unlike a stroke, does not cause irreversible damage to the brain. At the same time, scientists urge not to ignore dangerous signs, since they also require emergency medical attention. This helps prevent the stroke itself and the resulting irreversible brain damage.

As the authors of the study explained, the fact that TIA is often a harbinger of stroke was known in the past, but it was necessary to determine how much time the patient had to receive the necessary preventive treatment. The results showed that therapy should be started as soon as possible after TIA. Only this will help prevent the most serious consequences that inevitably accompany a stroke.

Symptoms of a TIA include headache, sudden dizziness, loss of consciousness, temporary speech impairment or loss of vision, hemiparesis (weakness in one side of the body), hypesthesia (numbness), or paresthesia (tingling).
