What are the symptoms of cerebral infarction

summary

? The number of cerebral infarction in our life is not once or twice, and the reason why this disease is loved by people is because the number of people infected with this disease is relatively large. Experts say that for cerebral infarction, what we ordinary people should master is its pre onset symptoms. Now, let's learn about it.

What are the symptoms of cerebral infarction

Suddenly appear in front of the eyes black, can not see objects, a few seconds or minutes to return to normal, neither nausea, dizziness, nor any disturbance of consciousness. This is caused by transient retinal ischemia, suggesting that intracranial hemodynamic changes or small thrombus temporarily block the retinal artery, which is the earliest warning signal of cerebrovascular disease.

Nausea and vomiting or strangulation, or blood pressure fluctuation accompanied by dizziness or tinnitus, unexplained recurrent nasal bleeding, often as a short-term harbinger of high blood shielding brain blood. Dizziness, headache suddenly aggravated or from intermittent headache to persistent severe headache. It is generally believed that headache and dizziness are the precursors of ischemic cerebral infarction, while severe headache with nausea and vomiting are the precursors of hemorrhagic cerebral infarction.

Drowsiness and drowsiness are characterized by continuous yawning, especially by hypoxia in the respiratory center. With the aggravation of cerebral arteriosclerosis, the lumen of artery becomes narrower and narrower, and cerebral ischemia worsens seriously. About 80% of people yawn frequently 5 to 10 days before the onset of ischemic cerebral infarction. Therefore, we must not ignore this important alarm signal.

matters needing attention

The energy and physical strength of the elderly are limited, so they prefer to sit still and read newspapers, or lie down quietly and listen to the radio. Adequate rest is very necessary, but appropriate activities can also improve the blood circulation of the brain and prevent cerebral infarction.
