Cerebral infarction is a sequela of cerebral infarction, which is due to cerebral atherosclerosis, thickening of blood vessel walls and narrowing of blood vessel cavities, so that blood cannot be supplied to the brain in a timely manner, resulting in cerebral ischemia and hypoxia, and in severe cases, nerve tissue will be compressed at the lesion, resulting in limb dysfunction or speech dysfunction. The main symptoms of limb dysfunction are unstable walking, inability to take care of oneself, and numbness of limbs. This condition can be treated with nerve-nourishing drugs, and can also be treated with limb rehabilitation training, allowing patients to walk and exercise as much as possible. Patients should abstain from smoking and alcohol in daily life, eat less spicy and stimulating food, avoid excessive mental stress, emotional tension and overwork. Patients can also restore limb function through acupuncture and massage.
