Don't bear it if you have this symptom

Some people think that stroke is more likely to occur in cold weather. However, modern medical research has found that summer is also a high-incidence season for stroke, so you should not be paralyzed. When the temperature rises above 32°C, the incidence of stroke can be 66% higher than usual, and the risk will increase with the increase in temperature. In stroke treatment, time is life. Delayed treatment often leads to injury or disability of the patient, or even endangers his life. Professor Zhang Yunling, president of the Oriental Hospital of Beijing University of Chinese Medicine, believes that the 1 to 14 days before a stroke is the "near-stroke period", during which 9 precursor symptoms often appear. Identifying the signs of stroke and providing ultra-early treatment can greatly reduce the patient's disability and mortality rates.

1. Fatigue and drowsiness

About three-quarters of people experience general fatigue and drowsiness before a stroke. This fatigue often has no clear cause, such as exercise or fatigue. Unexplained fatigue, drowsiness, and frequent yawning are the most common symptoms, which are often manifestations of ischemia of the cerebral cortex and reticular activating system.

2. Abnormal temperament

The patient's personality changes dramatically at this time, as if he has become a different person; he may become talkative and impatient, or taciturn, or childish and funny, or he may have impaired short-term memory and reaction ability. Some people suddenly lose interest in their original hobbies, some people suddenly don’t like their favorite foods, and their facial expressions become dull. These characteristics can be summarized as "face changing", which is mostly caused by insufficient blood supply to the frontal lobe of the brain.

3. Sudden headache

Unbearable localized headache occurs, or the form of headache is different from usual, such as the headache changes from a general headache to a localized headache, intermittent headache becomes a continuous headache, and the headache is accompanied by nausea and vomiting. This is often a precursor to subarachnoid hemorrhage or other cerebral hemorrhage.

4. Dizziness

Sudden dizziness, unsteadiness, or even fainting may occur, and may be accompanied by tinnitus, double vision, or nausea, but the condition quickly returns to normal. This may be a mini-stroke, or transient ischemic attack. If orthostatic hypotension, hypoglycemia, cervical spondylosis and other causes can be ruled out, it is often a precursor to a stroke because insufficient blood supply to the vertebral-basilar artery system affects the balance function of the cerebellum.

5. One eye turns black

One eye suddenly loses vision and then regains vision after a few seconds to tens of seconds. This is medically called amaurosis. It may be a visual impairment caused by cerebral ischemia and is a signal of an impending stroke. This is related to insufficient blood supply to the brain, which affects the function of the visual center.

6. Disadvantage of language

When local brain ischemia occurs, the language center malfunctions, which manifests as the tongue suddenly becoming stiff, unclear speech, or sudden inability to understand what others say. This often occurs transiently. The cause of this is related to the insufficient blood supply to the cerebral arteries before the stroke, which affects the function of the language center in the cerebral cortex.

7. Swallowing and coughing

Some patients experience choking and coughing when eating or drinking before the onset of the disease. This is a manifestation of damage to the glossopharyngeal nerve after cerebral ischemia.

8. Numbness on one side of the body

Sudden numbness of half the body, most prominent in the hands and feet, and weakness of the limbs on the same side. These symptoms are caused by insufficient blood flow to one cerebral hemisphere, affecting the area of ​​the brain that regulates limb movement.

9. Unexplained fall

Some patients may suddenly fall while walking normally on a flat road before a stroke occurs, and sometimes even trip over their right foot with their left foot. This is often a manifestation of cerebellar ischemia.
