Abstract

A late onset progressive dysfluency following a right hemisphere stroke occurred in a 62-year-old male. Dysfluency was characterized by pronounced word and phrase reiterations, and sound and syllable reiterations to a lesser degree. Spontaneous speech was significantly more dysfluent than oral reading and repetition. Recitation and singing were minimally dysfluent. Reiterations were accompanied by reduced vocal loudness and increased rate of speech. Reiterations occurred in initial, medial, and final sentence position. Secondary symptoms such as facial grimacing were absent. In contrast to acquired cortical stuttering which is characterized by a preponderance of sound and syllable sentence initial repetitions, dysfluency was more closely characteristic of palilalia. The dysfluency occurred as a symptom of a diffuse nonspecific subcortical projection system defect related to massive infarction in the right middle cerebral artery distribution with associated atrophy.

      Less common and therefore perhaps not recommendable are neurologic stuttering (Quinn & Andrews, 1977) and neurological stammering (Inglis, 1979). More problematic are a few labels that refer to the nature or the localization of the underlying brain damage, namely stroke-associated stuttering (see for instance Fawcett, 2005; Grant, Biousse, Cook, & Newman, 1999) and cortical stuttering (Horner & Massey, 1983; Rao, 1991; Rosenbek, Messert, Collin, & Wertz, 1978). These labels may be quite correct to designate that in a given case the stuttering occurred in association with a stroke or resulted from a cortical lesion, respectively.

      For example, as mentioned above, in Rosenbek et al.'s (1978) case series, a 53-year-old right-handed subject exhibited stuttering following a right parietal vascular injury. Horner and Massey (1983) reported of a 63-year-old right-handed person with dysfluent speech following the right internal carotid artery occlusion with left-sided hemiplegia, central facial weakness, hyperreflexia and Babinski sign. In yet another study, Lebrun and Leleux (1985) reported of a 26-year-old right-handed subject who evidenced stuttering symptoms following damage to the right hemisphere.

      In our patient we noted her dysfluency accompanying other neurological deficits, an absence of secondary features, no adaptation effect, the sudden onset of the dysfluency, and the occurrence of sound and syllable repetitions primarily on the first sound of words. These are typical characteristics of neurogenic stuttering as described by Horner and Massey, 1983; Ludlow et al., 1987; and Tippett and Siebens, 1991. Our patient later developed hypokinetic dysarthria, apraxia of swallowing, and language and cognitive dysfunction.
