读了天津医药杂志第六卷第十一期所载《口吃的发病与治疗》一文后,愿对口吃的发生机制提出个人看法:口吃的发病机制尚无定论,笔者认为患者大脑皮层内形成了与口吃有关的兴奋灶。从条件反射的形成来看,多数患者的口吃是学来的,但学过口吃的儿童很多,而形成口吃的为什么只是少数呢?这由于患者注意力集中,致使口吃反射兴奋灶形成,由于负诱导的关系,患者口吃时不能把全部精力集中在自己的思考内容和表达的过程中去,而是注意口吃现象,使口吃加重。患者认为口吃是难堪的,害怕口吃,尽力去摆脱它,但无能为力,是由于惰性兴奋灶的存在,患者讲话时挤眼、伸舌、重言,也可能由于情性兴奋灶的存在,是皮层的抑制引起皮层下机能的兴奋现象。口吃与病理性条件反射性疾病有相同之点。例如百日咳是长期反复咳嗽,在大脑皮层中形成了兴奋灶,外 After reading the article titled “The Pathogenesis and Treatment of Stuttering” in the eleventh issue of the sixth volume of Tianjin Medical Journal, I would like to put forward a personal view on the mechanism of stuttering. The pathogenesis of stuttering is inconclusive. In my opinion, the formation of Exciting stove and stuttering. From the formation of conditioned reflexology, most patients stutter is learned, but learned a lot of stuttering children, and stuttering why only a few? This due to patient concentration, resulting in stuttering reflex excited stove to form, due to negative Induced relationship, the patient stuttering can not focus all their own thinking content and expression in the process, but to pay attention to stuttering, stuttering. Patients think that stuttering is embarrassing, afraid of stuttering, try to get rid of it, but powerlessness is due to the existence of inert excitement stovepipe, patients wink, stretch their tongue, stress, may also be due to the existence of emotional excitement is the cortex Inhibition of excitement caused by subcortical function. Stuttering and pathological conditions of reflex disease have the same point. For example, whooping cough is a long-term repeated cough in the formation of the cerebral cortex excited stove, outside
