The prognosis of mild cerebral infarction in patients in their 40s is better, but attention should be paid to secondary prevention to prevent the recurrence of cerebral infarction with serious consequences. Young and middle-aged patients with mild cerebral infarction have milder symptoms and are often given treatments that nourish the nerves, improve brain metabolism, and scavenge oxygen free radicals, etc. The prognosis of these patients is usually better, and fewer of them will have residual dysfunctions. For young and middle-aged stroke patients, active secondary prevention should also be carried out to prevent stroke recurrence. First, risk factors for cerebrovascular disease should be removed, such as smoking cessation, control of blood glucose, blood pressure and blood lipid levels. Secondly, antiplatelet aggregation and lipid-lowering therapy should be given for the cause of cerebral infarction, and commonly used drugs are aspirin and atorvastatin. Patients with cerebral infarction should standardize the treatment under the guidance of doctors, and if they feel unwell, they are recommended to go to the hospital in time to avoid delaying the treatment.
