What are the symptoms of a small stroke

The medical name of "small stroke" is "transient ischemic attack", which is easy to appear in patients with hypertension, hyperlipidemia or hyperglycemia. The symptoms are sudden numbness and weakness of one hand and foot, dizziness, tinnitus, blurred vision, unclear speech or sudden loss of balance, lasting only a few minutes to about an hour, and will disappear completely within 24 hours.

Appear dark, suddenly in front of black, can't see things, a few seconds or a few minutes to recover. The symptoms of amaurosis are caused by transient ischemia of retina, insufficient blood flow into ophthalmic artery of carotid artery branch due to carotid artery stenosis, resulting in temporary amaurosis. Suddenly, the eyes can't see things, and can see again after 1-2 minutes. The occurrence of transient amaurosis is regarded as the earliest warning signal of cerebrovascular disease.

There are about 80% ischemic apoplexy in yawning. In 5-10 days before the attack, friends often yawn. Studies have found that when the cerebral arteriosclerosis gradually worsens, the lumen becomes narrower and narrower, cerebral ischemia and hypoxia worsen, the content of carbon dioxide in the blood increases, stimulating the respiratory center and causing yawning, which is an important warning signal.
