Half-body numbness of cerebral thrombosis, if it is a relatively mild sequela, may be gradually reduced within one or two weeks; in serious cases, it may take about half a year to be reduced, and may even exist all the time. Whether and for how long the half-body numbness of patients with cerebral thrombosis can be recovered depends mainly on the severity of the disease and whether the treatment is timely. If the area of cerebral infarction is small and timely treatment has been provided, the hemianesthesia may start to recover in one or two weeks and return to full normal in about one month. However, if the cerebral infarction is large, or the sensory center is seriously damaged, then it may take half a year or even longer to reduce the situation, and some of the sequelae of sensory impairment may not be able to recover. Patients with cerebral thrombosis should actively seek medical treatment, and actively carry out treatment under the guidance of doctors, so as to reduce the possibility of leaving sequelae.
