It takes about 3 months for the brain to recover from bruising, and it must be clear that not all functions are restored. It is a characteristic of nerve cells that they cannot regenerate once they are necrotic. Because this part of the brain is in charge of very important centers of the body, such as limb movement and speech function, once the ischemia and necrosis cannot be regenerated, the state of limb movement or speech function will not be restored to the original state. Although some can be restored through neurological compensation, more often than not, the original degree of restoration is not possible, so this point must be clear. And even after a series of exercises to recover, the time is very long, most of them need 3-6 months, or even about 1 year to have a more obvious recovery process. So be sure to clarify their own condition early intervention, early treatment, which is more conducive to speed up the recovery process of the disease.
