Hospitalization is recommended for mild cerebral infarction. Healing of mild cerebral infarction: patients with mild cerebral infarction can survive for a long time after treatment with neurotrophic drugs and functional exercises, which does not affect life expectancy. High recurrence rate of cerebral infarction, hospitalization is recommended: In China, the recurrence rate of cerebral infarction is 30% in the first year, 40% in the second year, and nearly 80% of cerebral infarction has recurrence of different degrees in 5 years. Although patients with mild cerebral infarction have a better recovery after active treatment, which may not affect their daily life, the recurrence rate of cerebral infarction is high, and it is recommended to hospitalize them to have an active treatment and to investigate the causes of cerebral infarction. There are many types of cerebral infarction, and the causes of each type of cerebral infarction are different, such as atherosclerosis of large arteries, atherosclerosis of small arteries, cardiac cerebral infarction, cryptogenic cerebral infarction, and so on, and the treatment programs for each type of cerebral infarction are different as well. Therefore, it is recommended that patients with cerebral infarction, regardless of the severity of the disease, should be hospitalized to clarify the cause of the disease and actively treat it to prevent recurrence.
