This study was conducted to investigate the degree of accuracy with which three groups of listeners could use perceptual analysis alone for identification of specific dysarthria types. The dysarthria types to be identified in this study were identical to those described by Darley, Aronson, and Brown (1969a): Flaccid, Spastic, Ataxic, Hypokinetic, Hyperkinetic Chorea, Hyperkinetic Dystonia, and Mixed. Each group demonstrated minimal success in the accurate identification of specific dysarthria types. Factors that possibly contributed to this poor success and potential implications are discussed.

Rate and regularity of diadochokinetic syllable repetitions of /p/, /t/, and /k/ in 30 normal subjects, 30 subjects with spastic dysarthria, and 30 subjects with ataxic dysarthria were measured by computer. Normal subjects had rates (syllables per second) of 6.4, 6.1, and 5.7; spastic dysarthric subjects, 4.6, 4.2, and 3.5; and ataxic dysarthric subjects, 3.8, 3.9, and 3.4 for /p/, /t/, and /k/, respectively. Spastic and ataxic subjects were significantly slower and more variable than normal subjects and ataxic subjects were significantly more variable than spastic subjects. The significantly slower than normal rate of repetition in the ataxic subjects and the significantly more variable than normal rhythm of repetition in the spastic subjects were unexpected findings and are in contrast with results from perceptually based investigations of dysarthria. The study demonstrates that slowness of syllable repetition is not restricted to spastic dysarthria and that dysrhythmia of syllable repetition is not restricted to ataxic dysarthria, thus suggesting the need for additional quantitative measurements of acoustic features on which certain notions about the dysarthrias are currently based.

The diagnosis of subcortical arteriosclerotic encephalopathy of Binswanger should be confirmed neuropathologically by postmortem examination. But we expect that it may be possible to diagnose provisionally as Binswanger's disease on the basis of clinical course and findings including computed tomography. Two cases, 57 years old postman (case 1) and 60 years old housewife (case 2) were reported. They had hypertension for over 20 years in their past history and showed a progressive dementia since before one year and 9 years. Transient syncopal attack and epileptiform seizure revealed occasionally. Psychiatrically either of them were apathetic, aspontaneous and autistic. One of them (case 2) showed a striking paranoid-hallucinatory state. Spastic gait disturbance and dysarthria are found neurologically, and moreover in case 1 revealed the incontinence of urine and feces. Arteriosclerotic changes were seen in the fundi. The EEG showed a slow alpha rhythm with scattered theta- and delta-waves. Laboratory data of blood, urine and CSF were normal. On the basis of these clinical course and findings the diagnosis of Binswanger's type of cerebral arteriosclerosis were suspected. The CT-scan of 2 cases proved a symmetrical enlargement of the lateral ventricles and marginated areas of definite abnormal low density in the white matter of the occipital (case 1) and frontal (case 1 and 2) lobes. Conclusively we may provisionally diagnosed our two cases as Binswanger's disease, also supported by the findings of CT.

The primary objective of the present study was to document tone production and intelligibility deficits in Mandarin-speaking persons with cerebral palsy (CP). Spastic, athetoid, and mixed types of CP were studied, along with a control group, to investigate the possibility of tone production and intelligibility deficits that were differentially affected by type of CP. Speakers produced a 78-word list that included contrasts for all four Mandarin tones. Intelligibility data were obtained for these words from 26 native speakers of Mandarin, and F0 contour analyses were implemented in CSpeech (Milenkovic) for a subset of the words. Mean tone intelligibility for speakers with CP was 73%, significantly different from the 91% value for control speakers. F0 contour analysis showed that speakers with CP maintained some contrast among the F0 contours for the four tones, but with less distinction than contrasts observed for control speakers. Discussion focuses on the role of tone in a model of the dysarthria associated with CP.
