Eight Stroke Sirens

Siren 1. Numbness in one limb

Strictly speaking, this is a light stroke. Research data shows that more than half of people will have obvious ischemic stroke 3 to 5 years after a transient ischemic attack.

Siren 2. Blurred vision occurs repeatedly

Temporary visual impairment or visual field defects usually recover spontaneously within 1 hour, but they can recur repeatedly, several times a day, and can occur once every few weeks, months, or years.

Siren 3, Transient Darkness

That is, suddenly there is blackening in front of the eyes, and nothing can be seen. It will recover in seconds or minutes, and it is accompanied by nausea, vomiting, dizziness, and disturbance of consciousness.

Siren 4. Frequent yawning

When the cerebral arteriosclerosis gradually worsens, the lumen becomes narrower and narrower, and cerebral ischemia and hypoxia increase, especially when the respiratory center is hypoxic, it will cause yawn reflex. About 80% of people yawn frequently before stroke, which usually occurs 5 to 10 days before the onset of ischemic stroke.

Siren 5, memory loss

A few months or years before the onset, there may be memory disorders, such as memory loss, forgetfulness, and inattention.

Siren 6, dizziness after turning his head

Turning the head can cause carotid artery distortion, which in turn aggravates arterial stenosis, resulting in insufficient blood supply to the brain. Therefore, when the patient's head turns to one side, they may suddenly feel dizzy and have a headache, and they can completely return to normal within a minute or two.

Siren 7, severe drowsiness

Suddenly, lethargy differs from daily habits, and can not be relieved for more than a few days, accompanied by emotional instability, irritability and irritability.

Siren 8, stuttering suddenly

Manifested as drooling, unfavorable speech, and drooling.

Anyone who has one of the above symptoms should go to the hospital for examination as early as possible to effectively avoid the occurrence of stroke.
