What are the symptoms of cerebral infarction?

Cerebral infarction, medically known as cerebral infarction or ischemic stroke, is a severe condition caused by the interruption of blood supply to the brain, resulting in brain tissue necrosis or softening. The severity of symptoms varies, and mainly includes the following manifestations:

1. Early symptoms: may include headache, dizziness, vertigo, and transient limb numbness or weakness. These symptoms often develop gradually and commonly occur during rest or sleep. A minority of patients may have a history of transient ischemic attack before the event.

2. Hemiplegia: sudden weakness of the face, arm, or leg, especially on one side of the body.

3. Facial droop: the mouth may twist to one side, accompanied by drooling.

4. Language impairment: slurred speech or difficulty understanding speech.

5. Visual disturbances: possible visual field defects, blurred vision, or temporary blindness.

6. Other symptoms: as the condition progresses, patients may develop conjugate gaze deviation toward the affected side, central facial palsy and tongue paralysis, pseudobulbar palsy (e.g., coughing while drinking and swallowing difficulties), gait instability, and urinary or fecal incontinence.

In some cases, patients may suddenly fall into a coma. Immediate medical attention should be sought if any of the above symptoms occur. Preventive measures include controlling chronic conditions such as hypertension, diabetes, and hyperlipidemia, quitting smoking, limiting alcohol consumption, and maintaining a healthy lifestyle.
