Head impact may cause cerebral infarction, but the chance of this happening is small. Cerebral infarction is a kind of cerebrovascular disease in which blood circulation in the brain is impaired and limited brain tissues are necrotic or softened due to ischemia and lack of oxygen. When the head suffers from a severe impact and causes the internal brain tissues to be affected, which leads to the impairment of local blood circulation and the damage and necrosis of a certain place of brain tissues, it is possible to cause cerebral infarction, and this kind of cerebral infarction is usually known as traumatic cerebral infarction. This kind of infarction is usually called traumatic cerebral infarction. The chance of occurrence of traumatic cerebral infarction is not high, but once it occurs, the patient may suffer from headache, dizziness, nausea, vomiting and other abnormalities, and with the progression of the disease, it may also cause movement disorders, hemiparesis of the limbs, unsteady gait, difficulty in eating and drinking, and slurred speech and other symptoms. Once the patient has the above symptoms, he/she should go to the hospital for treatment in time to avoid delaying his/her condition.
