Mild cerebral infarction symptoms

Mild cerebral infarction is a manifestation type of cerebral infarction. Of course, this mild cerebral infarction is also the least serious of cerebral infarction. However, there are still many symptoms of mild cerebral infarction, which makes it easier for people and doctors to make accurate judgments. Cerebral infarction is a brain disease in our human body. The harmfulness of this disease is quite large, so many people in reality are basically "terrified" every time they hear about this disease.

Mild cerebral infarction is much milder than general cerebral infarction, which means the treatment of mild cerebral infarction is much faster than general cerebral infarction. Therefore, patients with mild cerebral infarction can generally recover relatively quickly. Of course, this is what everyone is happy to see. So, let me first introduce the symptoms of mild cerebral infarction.

Cerebral infarction is a cerebrovascular disease caused by cerebral atherosclerosis and vascular endothelial damage, which leads to narrowing of the cerebral artery lumen, and then local thrombosis due to various factors, which aggravates the arterial stenosis or completely blocks it, resulting in ischemia, hypoxia, necrosis of brain tissue, and neurological dysfunction.

Symptoms of a mild stroke are as follows:

(1) It is more common in middle-aged and elderly patients with diseases such as atherosclerosis, hypertension, and diabetes. There are often signs of disease that may have been the source of the embolus, such as heart disease, especially atrial fibrillation, or valvular heart disease.

(2) There is often a transient ischemic attack before, such as dizziness, vertigo, weakness on one side of the limbs, etc., which has a slow onset and often occurs during sleep or quiet time. However, those caused by emboli usually have no prodromal symptoms, develop suddenly, and develop to the peak within a few minutes.

(3) There are less severe whole-brain symptoms such as impaired consciousness and intracranial hypertension. The main symptoms are focal brain dysfunction, which varies according to the affected blood and bone sites: for example, monocular blindness on the same side and hemiplegia on the other side in the case of internal carotid artery occlusion; complete hemiplegia, sensory impairment, and ipsilateral hemianopsia on the other side in the case of middle cerebral artery occlusion; and dizziness, nausea and vomiting, hoarseness, dysphagia, ataxia, decreased superficial sensation of the face on the same side, decreased superficial sensation of the contralateral limbs, or mild hemiplegia in the case of occlusion of the posterior inferior cerebellar artery.

(4) In addition to brain signs, embolic signs may also be seen in the skin, mucous membranes, retina, spleen, kidneys, heart, etc.

Patients with cerebral infarction often develop the disease when they are resting quietly. Some patients wake up and find that their mouth and eyes are crooked, they are hemiplegic, they are drooling, they drop rice grains when they eat, and they cannot lift their chopsticks. This is a cerebral infarction, which often catches people off guard. Only some patients have symptoms of transient cerebral ischemia before the onset of the disease, such as limb numbness, slurred speech, transient blacking out, dizziness or vertigo, nausea, and blood pressure fluctuations (which may be high or low). These precursor symptoms are generally mild, short-lived, and often ignored.

The general symptoms of mild cerebral infarction are those introduced above, namely: previous cerebral ischemia attack, dizziness; impaired consciousness, accompanied by nausea, vomiting, difficulty swallowing, etc. These are the common symptoms of mild cerebral infarction. Clinically, many doctors make disease diagnosis based on these symptoms of mild cerebral infarction.
