Elderly people’s inability to speak is mostly caused by cerebrovascular diseases such as cerebral infarction and cerebral hemorrhage, and it is recommended that they should be treated actively to avoid serious consequences. If the elderly have risk factors such as high blood pressure, high blood lipids, high blood sugar, etc., it may lead to arteriosclerosis, which can cause corresponding blood vessel narrowing and lead to cerebral infarction, cerebral hemorrhage and other diseases. The symptoms of cerebral infarction are mainly related to the severity of ischemia at the site of injury, whether there are other diseases before the onset of the disease, and whether there are combined injuries to important organs. Mild cases may show repeated limb numbness or dizziness, while severe cases may not only show limb paralysis, but even coma. If the lesion involves the frontal or temporal lobe, the patient may not be able to speak or understand other people’s language. Cerebral hemorrhage can also cause the symptoms of not being able to speak, which may be caused by the hemorrhage involving the patient’s speech center. Patients may have symptoms such as aggravation of consciousness, vomiting, headache, etc. They should go to the hospital in time and follow the doctor’s instructions to have a cranial CT examination. It is recommended to go to the hospital in time when you find that the elderly can not speak, and under the guidance of the doctor to carry out the appropriate treatment.
