Cognitive impairment in cerebral infarction can be reversed or even completely recovered after active treatment, depending on the size of the infarct, the timeliness of the medication and the effect of the treatment. 1.If the patient has cognitive impairment in cerebral infarction, the patient’s cognitive impairment can be completely recovered after the thrombolytic medication is given within the time window of thrombolysis and the blood flow of the blood vessel is restored smoothly and the cerebral nerve function can be completely restored. 2. If the time window of thrombolysis is missed, the patient’s cognitive impairment will be completely restored to normal after the active improvement treatment is given to the patient, so that the blood of the peripheral nerve cells of the necrotic brain tissue will be improved and a part of the replacement function will be produced. The patient’s cognitive impairment will also improve, but there will definitely be symptoms left behind. Patients should not be discouraged, as most patients will improve their symptoms through the recovery period after the acute phase.
