What are the manifestations of ischemic stroke in the early stages?

Transient ischemic attack: presents with transient motor or sensory disturbances, dizziness, or speech disturbances. Each attack lasts from a few minutes to dozens of minutes, generally no more than 24 hours, so it is called a mini-stroke.

About 25% to 40% of patients with transient ischemic attack develop a major cerebral infarction within 5 years. Transient ischemic attack is not only a form of ischemic stroke itself, but also a form of severe cerebral infarction. Jin Yongjian, a medical doctor in Japan, reminded that stroke is usually divided into ischemic stroke (cerebral infarction) and cerebral hemorrhage.

The most common type of cerebral infarction usually occurs at rest or during sleep, and it occurs suddenly. In fact, many patients do not have no symptoms before the onset of the disease. However, due to a lack of understanding or attention, serious cerebrovascular events occur.

Autumn and winter are the seasons with a high incidence of cerebrovascular diseases, and the incidence of cerebrovascular diseases in winter is twice as high as usual! Cerebrovascular disease precedes the onset of many signs, but because the symptoms are mild, they are easy to overlook. The following signals must be remembered!

Suddenly dizzy, you have a spinning and trembling sensation when you look at the outside world. In addition, there is a momentary blackening in front of the eyes, and the duration of the symptoms may vary from person to person. Some people have nausea or tinnitus.

Short-term language difficulties and fatigue often occur suddenly. A short period of time and twenty seconds can pass, and a long period of ten minutes or even hours can return to normal. ** After that, the patient did not leave any sequelae.

Remember, this is a precursor to cerebral ischemia. Sudden, severe headache.

If a hypertensive patient suddenly develops severe headache, dizziness, or vomiting, a high suspicion of cerebrovascular disease should be raised. Blood pressure should be measured immediately. Even if this phenomenon disappears on its own in a short period of time, we should be vigilant.

This phenomenon is recurrent, and patients may develop irreversible and reversible intracerebral hemorrhage.

Patients present primarily with transient, localized neurological dysfunction that lasts no more than 24 hours, resolves spontaneously, and does not leave positive neurological signs. Carotid artery numbness, weakness, sensory disturbances, monocular blackness, bilateral blackness, ataxia, dysarthria, dysphagia, co-directional hemianopia, unconstant location of each episode of paresis, often accompanied by occipital headache.

The symptoms that patients present in the early stage include sensory, motor, and language. If some people suddenly cannot hold a pen or chopsticks, the lower limbs on the same side will also be numb and inflexible, and the patient will also have slurred speech, and the corners of the mouth will be tilted to one side. If the condition is severe, there will also be headache, dizziness, nausea and vomiting, drowsiness, coma, etc.

There will be symptoms of numbness in the limbs, and it will also lead to sensory insensitivity, and it will also lead to the loss of some senses such as taste, smell, hearing, vision, etc., and it will also affect breathing and heart rate, and it will also cause weakness in the limbs, and it will also lead to poor balance, and nystagmus will also occur, and it will also cause confusion in thinking, and it will also lead to some symptoms such as difficulty walking, dizziness, etc.

Hemiplegia or weakness of the facial muscles, numbness, loss of sensory sensitivity, or decreased sensation of vibration may occur. There will be some changes in the sense of smell, taste, hearing, drooping eyelids, decreased reflexes, swallowing, poor pupil response to light, muscle weakness.

1. Transient ischemic attack (TIA) internal carotid artery ischemia is manifested as sudden limb movement and sensory impairment, aphasia, transient blindness in one eye, etc., and few impairments of consciousness. Vertebral artery ischemia manifests as vertigo, tinnitus, hearing impairment, diplopia, gait instability, and dysphagia. Symptoms are short-lasting and can be reversed, even several times a day or dozens of times.

It can be relieved on its own without leaving sequelae. There was no obvious infarction in the brain. 2. Reversible ischemic neurological deficit (RIND) is basically the same as TIA, but the neurological dysfunction lasts for more than 24 hours, and some patients can reach several days or dozens of days, and finally gradually recovers completely.

There may be small infarcts in the brain, most of which are reversible. 12. The symptoms of complete stroke (CS) are more severe than those of TIA and RIND, and they are constantly worsening, and there is often impaired consciousness. Significant infarction in the brain.

Neurological dysfunction cannot be recovered for a long time, and complete stroke can be divided into three types: mild, moderate and severe.

Stroke, commonly known as stroke, includes ischemic stroke (also known as cerebral infarction) and hemorrhagic stroke (including cerebral parenchymal hemorrhage, ventricular hemorrhage and subarachnoid hemorrhage), which is a disease of necrosis of brain cells and tissues, with obvious seasonality, and a higher incidence in the cold season. At the same time, the peak of onset in a day is usually a period close to noon and requires special attention.

Strokes usually develop rapidly (seconds to minutes). Stroke symptoms are related to the area of damage, so the symptoms are diverse. An ischemic stroke, which usually affects only brain tissue near the blocked artery.

Hemorrhagic strokes affect local brain tissue, but often also affect the entire brain due to hemorrhage and increased intracranial pressure. Based on the history, neurological examination, and risk factors, doctors can quickly diagnose the anatomical nature of the stroke (i.e., which part of the brain is affected) before the exact cause is known.

In the United Kingdom (UK), pre-hospital emergency care professionals are often expected to recognise strokes quickly. If a stroke is suspected, they usually use ldquo; The face arm says rdquo; test (FAST test) to assess the likelihood of stroke:

1.Face - See if there is any sagging or loss of muscle tone in the face.

2.Arm - Ask the patient to close their eyes and straighten their arm for 30 seconds - if the patient has suffered a stroke, you may see one arm slowly moving down.

If the affected brain contains one of the three central nervous systems: the spinal optic thalamic diameter, the corticospinal tract, and the dorsal spine (medial thalamus), symptoms may include:

1.Hemiplegia and weakness of facial muscles.

2.Numbness. 3.Sensory insensitivity or decreased vibrational sensation.

In most cases, the symptoms only affect one side of the body. Brain defects usually affect the opposite side of the body (depending on which part of the brain is affected). However, one of these symptoms does not necessarily indicate a stroke, as any lesion in the spinal cord can produce these symptoms.

In addition to the central nervous system mentioned above, there are 12 cranial nerves in the brainstem. Strokes that affect the brainstem can also produce these symptoms:

1.Alterations in smell, taste, hearing, or vision (in whole or in part).

2.Ptosis of the eyelids (ptosis) and weakness of the eye muscles.

3.Decreased reflexes: swallowing, poor pupil response to light.

4.Decreased sensation and muscle weakness.

5.Poor balance and nystagmus.

6.Changes in breathing and heart rate.

7.The sternocleidomastoid muscle is weakened and unable to turn its head.

8.Decreased tongue function (inability to extend and pan).

If the stroke is related to the cerebral cortex, the central nervous system can also be affected, and the following symptoms can also occur:

1.Aphasia (inability to speak or understand others).

2.Apraxia (loss of control of movements).

3.Visual defects.

4.Memory loss.

5.Half of the side has no feeling.

6.Thinking, confusion of consciousness, lewd gestures.

7.Denial is flawed.

If the stroke involves the cerebellum, the patient may have the following symptoms:

1.Difficulty walking.

2.Uncoordinated movements.

3.Vertigo. Hemorrhagic stroke, because of blood leakage compressing the brain, increased intracranial pressure, loss of consciousness, headache, vomiting usually occurs. If symptoms are most severe at the time of onset, the cause may be subarachnoid hemorrhage or embolic stroke.

Early symptoms of stroke: (Stroke is divided into ischemic stroke and hemorrhagic stroke) (1) Dizziness, especially sudden feeling of vertigo.

2) Numbness of the limbs, sudden numbness of one side of the face or hands and feet, some of which are numbness of the tongue and lips.

3) Temporary slurred speech or poor speech.

4) Limb weakness or inactivity.

5) Headaches that are different from usual.

6) Sudden fall or fainting for unknown reasons.

7) Brief loss of consciousness or sudden changes in personality and intelligence.

8) Obvious weakness of the whole body, weakness and weakness of the limbs.

9) Nausea, vomiting, or fluctuations in blood pressure.

10) Drowsy all day long, in a state of drowsiness.

11) Involuntary twitching of one or one limb.

12) Sudden feeling in both eyes that it is difficult to see what appears in front of you for a while.

Stroke usually does not have an obvious precursor because it occurs suddenly, so there is no precursor. However, if the patient suddenly develops numbness and weakness in the face or one limb, or if he cannot hear others, is confused, has a severe headache, and has difficulty walking, he or she should be alerted to a stroke.

To prevent stroke, you should always maintain a good mood, avoid bad mood, and pay attention to a light diet and avoid eating some overly greasy food.

Patients with stroke usually have certain aura symptoms, such as transient holding instability, accompanied by hemilimb numbness, hemiplegia and other symptoms.
