Precursor of cerebral infarction

Nowadays, the incidence of cerebral infarction is very high, and the onset of this disease is very acute. Generally, there are some signs when cerebral infarction occurs, but many times these symptoms are not very obvious, so it is easy for us to ignore them, which will aggravate the condition and cause great harm to the patient. So how can we prevent some harm? Everyone needs to understand the precursors of cerebral infarction.

Nowadays, cerebral infarction has become a disease with a high incidence rate, and the onset is usually very acute. If you do not understand its signs, it will easily cause some serious harm. Today we will introduce the precursors of cerebral infarction, and it is very useful to know more about it.

Clinical symptoms of cerebral infarction:

Transient visual impairment: Paroxysmal attacks of blurred vision or visual field loss. Symptoms and signs of cerebral infarction usually recover on their own within an hour. This is caused by occlusion of the central retinal artery or its branch arteries due to reduced cerebral blood flow, but no cranial nerve signs have appeared yet, which can be regarded as an early warning signal of cerebral infarction.

Frequent yawning: This is caused by the gradual aggravation of cerebral arteriosclerosis, the narrowing of the lumen, and the increasing cerebral ischemia and hypoxia. According to statistics, 80% of people who yawn frequently will have symptoms of cerebral infarction within 5-10 days before the onset of cerebral infarction. So don't ignore this signal.

Numbness in the hands caused by twisting the neck: It often occurs when the head is turned to one side to shave. The fingers suddenly feel weak and the razor falls to the ground. Some people may speak unclearly and recover after 1-2 minutes. This is because when you turn your head, the already hardened carotid artery twists, aggravating the stenosis. This phenomenon is enough to warn people that cerebral infarction can occur at any time.

Transient ischemic attack: transient hemiplegia or monoplegia occurs. The symptoms and signs of cerebral infarction may be accompanied by aphasia, but the duration is short and most patients recover completely within 24 hours, which indicates that a mild cerebral infarction has occurred. It can be regarded as a precursor to progressive or complete cerebral infarction.

Severe or sudden blood pressure fluctuations in the elderly: worsening headaches, dizziness, tinnitus, mental tension, fatigue, and drowsiness, etc., indicate the possibility of hemorrhagic stroke.

It is very necessary to understand the precursors of cerebral infarction, especially now that there are more and more patients with cerebral infarction. In the face of bad living and eating habits, everyone should pay attention to the occurrence of cerebral infarction. If we can know some signs of cerebral infarction, we can also prevent the occurrence of these diseases.
