The human brain is a complex and sophisticated structure, and the functional areas of the brain that govern language are mainly located in the frontal and temporal lobes. When cranial diseases such as cerebral hemorrhage affect the language function area, patients will have speech dysfunction, that is, they cannot speak, and this situation is divided into the following two types: 1. motor language center involving the frontal lobe: patients will show that they can understand the meaning of other people’s speech, but cannot express their own meaning correctly, others will feel that the patient is talking nonsense, but the patient is often able to follow the This type is called motor speech disorder; 2. Sensory speech center with lesions in the temporal lobe: In this case, the patient is unable to understand the meaning of others’ speech, but the patient speaks coherent words, and others will feel that there is no way to communicate with the patient normally, which is called sensory aphasia, or sensory speech disorder.
