Mild cerebral infarction at age 50 usually does not affect life expectancy if the infarct size is small and the symptoms are mild. Mild cerebral infarction usually means that the infarct area is small and does not involve important parts of the brainstem and basal ganglia, and the symptoms are relatively mild, with only mild sensory activity dysfunction of one limb, unfavorable speech and crooked mouth, and the patient may have inconvenience in life, but it usually does not affect the patient’s life expectancy. Patients with mild cerebral infarction should prevent secondary recurrence after clinical cure. Patients with high-risk factors such as hypertension, hyperlipidemia and diabetes need to actively take medication under the guidance of doctors and should not stop medication on their own to smoothly control blood pressure and blood sugar. In addition, patients need to improve poor lifestyle habits, quit smoking and limit alcohol, reduce sugar and fat intake, eat more cereals, fresh vegetables and fruits, and ensure proper exercise. If obese, they also need to lose weight. Once a patient has a recurrence of cerebral infarction, he or she needs to be rescued in time, and it is better to do thrombolytic therapy early. It is recommended to call the emergency number 120 at the first time and avoid driving or taking a taxi to the hospital by yourself to avoid delaying the condition.
