Cognitive dysfunction caused by cerebral infarction is mainly due to the state of ischemia and hypoxia after cerebrovascular disease, resulting in the decompensation or loss of brain cell function of the patient, for cognitive dysfunction caused by cerebral infarction, the following aspects can be adjusted: 1. The patient’s family can give the patient language stimulation, including the language stimulation of close relatives, such as asking the patient what he ate at noon, what he ate last night, how many children, what is the name of the children, or home address, which is one aspect. The patient’s family can provide verbal stimulation to the patient, including verbal stimulation from close relatives, such as asking the patient what meal he ate at noon, what meal he ate last night, how many children he has, what the children’s names are, or his home address, which is one aspect. 2. There are also empirical drugs in China, such as Amlisin and Megamind, which are recommended by the FDA and are now available in China, and empirically used drugs with good effects, such as cytarabine sodium, nimeglumine, olanzapine, ginkgo biloba preparations, etc. These drugs can be given to patients for trial. But remember that the cognitive dysfunction caused by cerebrovascular disease is a long-term process, do not think that the patient will have a significant improvement in cognitive dysfunction in a short period of time after the drug is given, this idea is unrealistic.
