The causes of stuttering include genetic factors, damaged articulatory organs, strong imitation ability, personality factors, improper education, etc. Stuttering is related to multi-level and multi-gene genetic factors, with family aggregation. Damage to the articulatory organs is also related to the occurrence of stuttering, such as pharyngeal lesions. If one grows up in an environment with stuttering and has a strong ability to imitate it as a child, it will also gradually become habitual stuttering. Personality factors are also a common cause of stuttering. If you do not like to interact with people, shy and introverted, you will be nervous and anxious when communicating with people, and thus stuttering will occur. If the process of education is too harsh, it can also lead to stuttering problems in children. Once stuttering occurs, language training should be conducted and anti-anxiety medication can be taken under the advice of a doctor. At the same time, it is necessary to strengthen the self-confidence of the stammering patient and to guide him or her patiently so that he or she can relax in order to gradually improve the symptoms of stammering.
