What are the signs of a stroke? What are the precursors of a stroke

The occurrence of stroke is often accompanied by the appearance of several symptoms, which can help patients quickly identify these symptoms, and these symptoms can not be ignored by family members or themselves. Some of the more common signs include:Transient amaurosis fuchow, transient visual impairment, frequent yawning, neck twisting and hand numbness, transient ischemic attack, and severe or rapid fluctuations in blood pressure in the elderly

1. Transient blackness:Appears suddenly in front of the eye and recovers within seconds without nausea, vomiting, impaired consciousness, or paralysis of the limbs. This is caused by reduced intracranial blood flow or tiny blood clots passing through the retinal arteries.

Because the ophthalmic artery is the first branch of the carotid artery and is most sensitive to carotid arteriosclerosis, stenosis, and ischemia, it can be regarded as the earliest warning sign of stroke.

2. Transient visual impairment:Blurred vision or visual field defects, paroxysmal seizures, usually recover spontaneously within an hour. This is the result of occlusion of the central retinal artery or branched artery due to reduced cerebral blood flow, but there are no signs of cranial nerve defect, which can be regarded as an early warning sign of stroke.

3. Frequent yawning:This is caused by the gradual aggravation of cerebral arteriosclerosis, the narrowing of the lumen, and the worsening of cerebral ischemia and hypoxia. According to statistics, in the first 5-10 days of ischemic stroke, frequent yawning can reach 80%.

So, don't ignore this signal.

4. Neck twisting hand numbness:Often, when the head is turned to one side to shave, the fingers suddenly feel weak, the razor falls to the ground, and some speak slurred, and it recovers after 1 or 2 minutes. This is because when the head is turned, the already hardened carotid artery is twisted, which aggravates the narrowing result.

This phenomenon is enough to warn people that strokes can occur at any time.

5. Transient ischemic attack:Transient hemiplegia or monoplegia may be accompanied by aphasia, but it is short-lived, usually with full recovery within 24 hours, indicating a mild stroke. Think of it as a precursor to a progressive or complete stroke.

6. Blood pressure fluctuates violently or surges in the elderly, headache, dizziness, tinnitus, nervousness, or drowsiness indicate the possibility of hemorrhagic stroke.

Frequent yawning, usually occurs six to ten days before a stroke, when cerebral arteriosclerosis progressively worsens and the lumen narrows. Blurred vision, visual field defects, often recover spontaneously within 60 minutes, indicating severe stenosis of the cerebral blood vessels. After the experience, the symptoms of stroke patients are also extremely obvious, and the patient's mobility will be impaired.

Weakness in the lower limbs, weakness in one or both legs, and wrestling can also occur on flat ground.

What are the precursors of stroke? Severe headache, limb weakness, obvious dizziness, onset of falls, hard tongue at the base of the tongue, and confusion of things.

There are about two types of strokes.

Hemorrhagic is called cerebral hemorrhage, generally with headache, or loss of consciousness, frequent during exercise, and then symptoms of nerve damage, hemiplegia, facial paralysis, choking on drinking water, difficulty swallowing, incontinence, etc., cerebral infarction is the same, but it is quiet because of blood vessel blockage.

Stroke may cause dizziness, dizziness, sluggishness, paralysis of one limb, numbness, slurred speech, or complete inability to speak, and even convulsions of limbs, confusion, nausea, vomiting, incontinence, etc.

Cerebral stroke is mainly problems such as crooked mouth and eyes, drooling, and high muscle tone of the limbs, which can be used with traditional Chinese medicine**, how long has the patient had such a condition.
