Abstract: Post-stroke aphasia is a common and disabling disease. The factors affecting the recovery of language function in aphasic patients include the location and size of injury, type of aphasia, and severity of stroke, etc. The individual factors include gender, age, handedness, educational level, and others. The mechanisms of recovery of language function include blood flow reperfusion, recovery of neural function linkage, disconnection of resuscitation structure and reorganization of language network functions. The right hemisphere may hinder the recovery of aphasia, and non-verbal-specific brain networks may relate to the occurrence of aphasia. For the treatment, in addition to classical speech-language therapy, non-invasive brain stimulation techniques, such as repetitive transcranial magnetic stimulation and transcranial direct current stimulation, are more and more used clinically; Other treatments include drugs, acupuncture and traditional Chinese medicine.
