The symptoms of a cerebral infarction patient vary in severity. For a mild cerebral infarction patient, he can take care of himself completely, but for a severe cerebral infarction patient, he may be bedridden and unable to take care of himself and needs to be taken care of by others to survive. A cerebral infarction is a blockage of a blood vessel in the brain that causes brain tissue necrosis, which affects the functional areas governed by the brain tissue and can cause paralysis and speech impairment. If a small blood vessel or the functional area where the blood vessel is located does not affect the normal life of the patient, after the attack, although the patient has a temporary disease phenomenon, after recovery, the patient can take care of himself. However, if there is an infarction in a large blood vessel or an infarction in an important part of brain tissue, the patient may become bedridden for a long time and need to be taken care of by others to survive.
