Whether the brain infarction is not serious can return to normal should be judged according to whether the treatment is timely, the infarction site and size, and part of it can return to normal. 1. Timely treatment: for less serious cerebral infarction, the clinical manifestation is relatively light, and the influence on the body is relatively small, after active medication and rehabilitation, the recovery is relatively good, and some of them can return to normal. 2. Site and size of infarction: if the infarction site is not the main functional area, such as the external capsule and other parts of the brain, the symptoms are mild and can be restored to normal; if the infarction area is small and the infarction is cavernous, the infarction can be restored to normal through drug treatment and exercise. If the infarction is not serious, even if it returns to normal, long-term oral drug treatment is needed for secondary prevention to avoid recurrence of infarction. When cerebral infarction occurs, it is recommended to seek medical treatment in time so as not to delay the condition and lead to adverse consequences.
