Stuttering is a speech disorder, the specific cause of which is still unclear and may be related to genetics, neurophysiology, child development and environmental aspects, which are not contagious, so stuttering is generally not contagious. However, it should be noted that if you repeatedly imitate the stuttering behavior of others, the language habits solidified, there will also be a certain amount of stuttering performance. Stuttering is a complex speech disorder, with the patient’s speech being obstructed as the main manifestation, which can be manifested by repeatedly repeating a word, always having a pause in the middle of the utterance, not being able to speak fluently, sometimes possibly extending the sound, such as umming and ahhing, and stuttering may be accompanied by rapid blinking, facial twitching, clenched fists and other symptoms. Treatment of stuttering is mainly non-pharmacological, including speech therapy, breathing training and psychotherapy, supplemented by medication when necessary, and usually has a good prognosis.
