Patients with short onset and mild disease have significant functional recovery in 2 to 4 weeks. For patients with severe disease, it will take half a year or more for gradual recovery. How long it takes for hemiplegic patients with cerebral infarction to recover needs to be judged according to the scope and location of the lesion, the severity of the paralysis, the timeliness of the treatment, the intensity of the rehabilitation training, and whether or not there are any complications and other factors. For mild cerebral infarction, patients can see obvious recovery within 2~4 weeks after active and effective rehabilitation. For patients with more serious condition and hemiplegia symptoms, it may take half a year or more to recover gradually, or even leave sequelae. It is recommended that patients with cerebral palsy who have developed hemiplegia should seek timely medical treatment under the guidance of professional doctors, which is conducive to the functional rehabilitation of patients as well as the prevention and treatment of complications, and improves the quality of patients’ survival and obtains the best recovery results.
