Aphasia arises mainly from organic damage to the language and related centers of the cerebral hemispheres, which causes dysfunction in one or more aspects of the patient’s perception and recognition, comprehension and acceptance, organization and expression of language. It is one of the most serious cognitive impairments caused by cerebrovascular disease. About 21-38% of patients with acute stroke have aphasia. It seriously affects the quality of life of patients. The brain is highly plastic. When a part of the brain is damaged, the function of the parts adjacent to it and those with similar functions is enhanced, and their workload increases accordingly. Therefore, recovery is possible even for the most severe aphasic patients. Classification of aphasia: 1. Motor aphasia: characterized by the patient’s difficulty in expressing himself and his inability to say what he would have originally said but had to say. Patients with this type of aphasia can understand the words of others, and their internal language is basically normal, but they cannot say what they have to say, nor can they repeat the words of others. Patients with mild motor aphasia have difficulty speaking fluently and effortfully, and often misspell words. The patient is able to detect any misspoken words and correct them after detection. The lesion is located in the posterior part of the inferior frontal gyrus. 2.Sensory aphasia: It is manifested by the lack of ability to understand language and produces the inability to comprehend. The patient has no auditory or visual impairment and can hear and see words and sentences, but cannot relate them to the corresponding image, concept or thing. The patient is completely unable to comprehend language, as if it were being associated with him in a language he does not understand. Since he does not understand what is being asked, he often answers the wrong questions and often speaks the wrong words or phrases, which the patient himself cannot detect. The lesion is located in the posterior part of the superior temporal gyrus. 3. Naming aphasia: characterized by inability to name and forgetting of nouns. Also known as amnesic aphasia, the patient cannot say the name of an object, but can tell its function. For example, if the patient takes out a pen, when he wants to say its name, he cannot say the word “pen”, but says it is used for writing. However, once reminded, the patient can immediately repeat the name of the object. 4. Mixed aphasia, where perceptual aphasia and motor aphasia coexist. The patient neither understands nor can express himself verbally. Mixed aphasia is the result of extensive lesions in the dominant hemisphere. Common training methods for aphasia: 1. Training of oral expression: First, we should conduct motor training of tongue muscle, facial muscle, soft palate and other articulatory organs, including cheek puffing, blowing, tongue stretching, elevation, left and right swing and soft palate elevation training, etc., so that the strength of lips, tongue and soft palate can be enhanced. Then the training of flexibility and coordination of articulation organs will be carried out, from simple to complex, in a gradual manner. 2. Training of listening comprehension disorder: Show 3 pictures of commonly used items each time, and let the patient point out the corresponding picture after saying the name of one item. At the same time, let the patient see the connection between the trainer’s mouth and lip movements and sound when pronouncing the words to achieve better results. 3. Training of word comprehension: Set out 3 pictures and 3 corresponding word cards at the same time and let the patient read them and practice the combination, or let the patient listen to the trainer read a word and then point out the corresponding word card, or train to read aloud by pointing out the word and repeating it. 4. Rehabilitation training of writing: It should start with copying and dictating words such as the patient’s name, and gradually move to sentences, until short essays. Finally, you can look at pictures of situations and write narratives, keep a diary, write letters, etc. Acupuncture for aphasia Acupuncture methods: tongue acupuncture (tongue three acupuncture), head acupuncture (speech area, temporal three acupuncture, head double acupuncture), body acupuncture (Renzhong, Neiguan, Sanyinjiao, Lianquan Heigu stab, Fengchi, Tongli). Recent studies have shown that acupuncture research focuses on aphasia, while paying attention to the overall treatment of stroke disease, especially in the acute phase. In the selection of acupuncture points, emphasis is placed on the head, neck, neck, tongue body and the points of the heart and kidney meridians, and the method of acupuncture emphasizes the local release of blood, deep stabbing and strong stimulation of the tongue. Acupuncture treatment for aphasia has a domestic efficiency of 78%~100%. In Japan, the efficiency of acupuncture for stroke aphasia is 30.8%.
