ABSTRACT
Acquired stuttering is a cover-term for two types of onset: neurogenic stuttering, which occurs following neurological trauma of varying aetiologies; and psychogenic stuttering, which may be related to a distressing event. Cluttering commonly occurs alongside a range of other speech/language disorders, most notably stuttering, which can further complicate differential diagnosis. Stuttering is characterized by learned behaviours that become attached to the primary activity, and include some concomitant features as sudden loss of eye contact, rapid eye blinking, hand tapping, head nodding, jaw jerk, tongue thrust and nostril flaring. Prevalence of stuttering refers to the number of cases that will be observed within any defined population and age group. Stuttering appears to be more prevalent amongst learning disabled (LD). Conture suggests that the increase in fluency arising when speaking to babies, pets and oneself all reflect the fact that stuttering is associated with bidirectional speech. Spontaneous recovery from stuttering in childhood remains one of the more perplexing features of the disorder.
