I. Introduction. The incidence of idiopathic speech and language dysfluencies and that of acquired speech and language dysfluencies can be distinctly differentiated as regards etiology. Acquired stuttering begins typically subsequent to some form of trauma to the head, resulting in brain damage and speech and language dysfluency.
II. Communication Breakdowns. Given head trauma as one cause of learning disabilities, language-learning disabled children earned a mean of 0.56 in conversation and narration communication breakdowns.
III. Perinatal Brain Damage. Children who had experienced perinatal brain damage evidenced several speech and language impairments when compared with their controls.
IV. Suspected Phenobarbital Addiction. The subject presented echolalia and echopraxia and evidenced 2,087 reiterations within a total speech sample of 5,489 words.
V. Alzheimer's Patients. Alzheimer's patients were found to rate lower means for immediate retelling of a story, etc. than their well-elderly counterparts.
VI. Discourse Cohesion and Coherence, Patients were diagnosed as being in the early, middle and late stages of Alzheimer's Disease, with attendant dysfluencies.
VII. Coordination Mechanisms. The production of speech entails a systems approach in which there occurs feedback information to control the output.
VIII. Conclusion. Researchers conclude dysfluency due to trauma.
The incidence of idiopathic speech and language dysfluencies and that of acquired speech and language dysfluencies can be distinctly differentiated as regards etiology. Wingate (Andrews, Craig, Feyer, Hoddinott, Howie & Neilson, 1983, p. 227) reports that idiopathic stuttering simply begins without the presentation of a clear cause. In contrast, acquired stuttering begins typically subsequent to some form of trauma to the head, resulting in brain damage. The results of such trauma entail that a previously fluent speaker undergoes chan...
