What are the precursor symptoms of stroke and what are the precursors of stroke?

Stroke is also known as stroke, and the early symptoms include dysfunction or abnormalities in many aspects such as language, vision, consciousness, sense, and movement.

1. Language disorder: mainly includes unfavorable or ambiguous speech, such as poor speech or difficult speech, such as ambiguity. 2. Visual abnormalities:

It can be manifested as blackness in front of the eyes, decreased vision, blurred vision, diplopia, etc., and can be short-lived. 3. Impairment of consciousness: characterized by mental discomfort, drowsiness or feeling sleepy all day.

Many patients yawn frequently, which is a sign of hypoxia. 4. Paresthesias: Patients often have numbness on one side, tongue, lips or limbs.

5. Movement disorder: It is mainly manifested as weak muscle strength on one side of the face or upper and lower limbs, which is uncontrollable. There may be deviations in the corners of the mouth, salivation, choking on water, etc.

6. Abnormal blood pressure: In the early stage of cerebral hemorrhage or subarachnoid hemorrhage, blood pressure fluctuations are often caused by emotional agitation, and most of them are hypertension.

For people with a history of hypertension, diabetes, hyperlipidemia, smoking, and hyperhomocysteinemia, if they or their family members have the above symptoms, it is likely to be a precursor to stroke, and they should immediately go to the emergency department of the hospital for timely intervention to avoid the formation of stroke.

Many people are unaware of the signs of stroke, and even when they do, they don't think about them or are unaware of them.

1. Dizziness. The precursor of stroke in middle-aged and elderly people will be repeated instantaneous dizziness, sudden feeling dizzy, visual rotation, and return to normal after a few seconds, which may be a transient ischemic attack, which is commonly known as a precursor to stroke, and should be diagnosed and treated as soon as possible to prevent stroke.

2. Numbness of limbs. In addition to cervical spondylosis and diabetes, if accompanied by symptoms such as headache, dizziness, lightheadedness, tongue swelling, or a history of hypertension, hyperlipidemia, diabetes or cerebral arteriosclerosis, etc., more attention should be paid to the occurrence of stroke.

3. Sudden blackening of the eyes. Sudden blackening of one eye, unable to see, and completely return to normal after a few seconds or tens of seconds, medically known as monocular transient amaurosis fugaurosis, which is the most common symptom of stroke aura in middle-aged and elderly people, because of retinal ischemia. Another sign of stroke is regurgitation, dizziness, reduced visual field, or diplopia, which may be a sign of brainstem ischemia.

4. Unexplained falls. Due to cerebral arteriosclerosis, cerebral ischemia is caused, and there is a weakness or atonic attack of one limb, which is prone to falling, and it is also a precursor symptom of stroke.

5. Unclear speech. When the cerebral blood supply is insufficient, the nerves of the human motor function fail, one of the common symptoms is that the common symptoms are suddenly ineffective or slurred, or even unable to speak, but the duration is short, no more than 24 hours, which should be paid attention to, and the unexplained crooked corners of the mouth, slurred speech or tongue protrusion deviation should be noted.

6. Yawn constantly. If there is no tiredness, lack of sleep, etc., there is continuous yawning, which may be due to cerebral arteriosclerosis, ischemia, and the manifestation of chronic ischemia and hypoxia of brain tissue, which is a precursor to stroke patients.

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.

Short-term blackening in front of the eyes, double shadows, numbness in the hands and feet, slurred speech, sudden dizziness accompanied by nausea, palpitation, sweating, etc.

Aurora signs of stroke: (1) Headache, dizziness, may be accompanied by visual rotation, nausea, vomiting. The headache does not look and feel the same as usual, but it worsens and becomes persistent, sometimes fixed in one spot, which is a sign of blood pressure fluctuations or cerebral vasospasm, which is often a precursor to a hemorrhagic stroke.

2) Various movement disorders: such as weakness on one side of the limbs, or inactivity, unsteady holding, sometimes accompanied by muscle spasms, although the end of the roadblock when walking, the consciousness is also clear, but suddenly fell to the ground, or they want to walk on the road**, but involuntarily tilt to the side of the road and appear walking instability; Sudden slurred speech and slurred speech; dysphagia, choking; The mouth is crooked and salivating. (3) Sensory impairment:

Numbness of the lips, face, tongue, limbs, tinnitus, hearing loss, transient blurred vision or blindness. Your dizziness and discomfort may also be caused by other factors, it is better to say anemia, usually eat more fruits and vegetables can prevent the occurrence of stroke, eat some pig blood and duck blood, can supplement the body with iron, prevent the occurrence of anemia.

The main signs of stroke are: dizziness and headache.

The head is swollen and dreamy. Lightheadedness, nervous breakdown.

Insomnia and forgetfulness. Difficulty concentrating.

Memory loss, emotional agitation.

Climb the stairs after eating.

Or feel palpitations after a little work.

Panic and chest tightness. Shortness of breath and chest pain.

General weakness. Weakness in the limbs.

Numbness of the limbs. Cold extremities.

Sore joints and tinnitus.

Blurred vision. The blackness in front of the eyes is abnormal.

Irritability, sluggishness, transient or persistent headache.

A migraine tingling sensation in the brain.

Lasts for 1-2 seconds, and then disappears from precordial pain during exertion, radiating pain to the left shoulder, numbness in the face, mouth, tongue, and extremities.

Drooling and slurring words.

Aphasia occurs acutely or gradually, with immobility or diminished mobility of one limb. Sudden, severe headache and confusion. Suddenly speak clumsily.

Sudden loss of sight in one eye or blurred vision in both eyes in the same direction. Dizziness, vomiting, unsteadiness in holding objects on one limb, swaying walking, and/or weakness in the limbs. Half of the limb feels numb, and the pain of pins and needles decreases.

Aura symptoms of stroke include: (1) high blood pressure

Sudden onset of headache, dizziness, blackening of the eyes, or headache fixed on one side with numbness and weakness of the contralateral limb in a person with a history of arteriosclerosis often indicates the occurrence of hemorrhagic cerebrovascular disease; (2) Speech is unclear and vision is blurred

Numbness and weakness of one limb is a typical manifestation of transient cerebral ischemia in the internal carotid artery system, and it is urgent to prevent cerebral thrombosis. (3) Middle-aged and elderly people suddenly have visual rotation, tinnitus, vomiting, inaccurate retrieval of objects, numbness and weakness of limbs and reflux, which is a manifestation of insufficient blood supply to the vertebrobasilar artery, indicating that the system will have severe ischemic cerebrovascular disease; (4) Heart disease.

When there is an arrhythmia, such as atrial fibrillation in rheumatic heart disease, the emboli in the left atrium can easily fall off and enter the cerebral artery and cause cerebral embolism.

About 70 or more people who have had a stroke often have the following aura symptoms before a stroke:

1.Transient ischemic attack: manifested by transient loss of consciousness, speech disturbance, dizziness or nausea and vomiting, sudden fall or simple diplopia, blindness, incontinence.

These symptoms can occur for a variety of lengths, from seconds, minutes, hours, but not more than 24 hours. Within 24 hours, the onset of symptoms can completely disappear without sequelae. If the author of transient cerebral ischemia does not accept **, he can reverse it, and the proportion of ** within a few weeks is the highest.

1 3 can develop into significant cerebral infarction. It is thought to be mostly not a transient ischemic attack, but a small vessel lacunar infarction.

2.Large fluctuations in blood pressure: In the absence of a specific trigger for blood pressure at the same dose or without a specific trigger, large fluctuations in blood pressure, such as high or low blood pressure, often become the trigger of hemorrhagic stroke.

3.Abnormal motor function and sensory function: such as inflexible limb movement, unstable holding objects, asymmetrical corners of the mouth, deviation to one side when protruding the tongue, unsteady walking, deviation of walking direction, numbness of limbs, especially unilateral, or accompanied by oral and facial numbness.

4.Abnormal mental state: abnormal personality, or taciturn, withdrawn, or excited, talkative, irritable; Some present with drowsiness and apathy.

5.Exacerbation of the original symptoms: headache, head swelling, palpitations, chest.

Symptoms such as stuffiness, irritability, and insomnia are significantly aggravated. Most hypertensive patients have some of the above symptoms before stroke, but some patients usually have no obvious symptoms, and the precursor symptoms before stroke are very mild, and they unknowingly develop cerebral hemorrhage. Therefore, patients with hypertension who usually have no obvious symptoms should have a sense of self-protection, maintain a high degree of vigilance, regularly self-measure their blood pressure, lower blood pressure steadily, and go to the hospital for timely examination if they are unwell.

The onset of stroke usually has certain aura symptoms.

In general, there are about five categories of aura symptoms, if these occur, it may indicate the possibility of stroke, the first aura symptom is paresthesia, which is a sudden sensory abnormality, such as sudden numbness of the tongue, numbness of the face or half of the body, or even tingling sensation. The second aura symptom is motor dysfunction, for example, when suddenly speaking, the tongue does not listen to the call, or the movement of the hands and feet is affected to a certain extent, such as easy to fall when walking. The third aura symptom is the onset of ischemia and hypoxia, such as the sudden appearance of blindness or dizziness, but these phenomena generally last for a few seconds, and can return to normal in more than ten seconds.

The fourth aura symptom is the occurrence of chronic hypoxia, for example, I always feel that I am prone to yawning in the recent period, that is, I feel that my mental energy is declining. The fifth situation is that during this time, there are some fluctuations in emotions, such as easy to be mentally and depressed during this time, or hyperenergetic, easy to lose temper, etc., if these five situations occur, then it indicates the possibility of stroke.
