The recovery time for cerebral infarction hemiparesis may take up to 3 months at the earliest, and the specific recovery time is related to the extent and location of the cerebral infarction, as well as the degree of treatment and the intensity of rehabilitation training. In patients who underwent thrombolysis and embolization treatment in the hyperacute stage, and the scope of the infarction is not particularly large, and the motor area is not completely damaged, this recovery is the fastest. Through thrombolysis, embolization treatment and early drug treatment, such as edaravone treatment to remove oxygen free radicals, cerebral protection treatment and butylphthalide treatment to improve microcirculation, the ischemic area of the brain can be effectively improved or restored, thus recovering quickly. half of the paralysis, which may take about 3 months. For some patients, if they miss the time of thrombolysis and embolism, they should undergo cerebral protection therapy and apply aspirin and atorvastatin as prescribed by the doctor, together with active rehabilitation exercises, generally within six months after cerebral infarction, about 80% of patients can recover most of their limbs, and about 20% of patients may have sequelae, mainly paralysis of limbs not fully recovered, or walking The remaining 20% of patients may have sequelae, mainly paralysis of the limbs that are not fully recovered or gait disorders. In some severe cases, such as brainstem infarction or large cerebral infarction, severe limb paralysis and quadriplegia may be caused, which may require active rehabilitation exercises in addition to medical treatment. For example, patients may experience limb stiffness and limb pain, which require appropriate rehabilitation exercises or even neuromodulation to improve. Most patients do not recover completely, but only a small portion of half of the symptoms of paralysis, and require constant rehabilitation and treatment to reduce muscle stiffness and muscle atrophy state, and rarely reduce the symptoms of paralysis.
