The further therapeutic benefit of piribedil when combined with amantadine or Levodopa was studied by a double-blind, cross-over trial in 15 patients with Parkinson's disease. A significant improvement at the 5 per cent level for akinesia, gait, speech disorder and facial expression occurred when piribedil was added to Levodopa; and a more highly significant improvement at the 1 per cent level for akinesia, facial expression and finger dexterity occurred with piribedil and amantadine. No significant improvement occurred for special timed tests. Improvement was associated with side effects in both groups of patients. Side effects occurred with both placebo and active piribedil. Only nausea during piribedil and Levodopa treatment reached statistical significance when compared with the placebo. Piribedil did not give rise to any haematological or biochemical complications. Our findings suggest that piribedil is of further therapeutic benefit when added to amantadine or Levodopa. It was suggested that the improvement which occurred together with amantadine could be due to the combined action of both drugs on dopamine receptors.

The respiratory abilities of a group of 19 speech-disordered subjects with idiopathic Parkinson's disease were assessed using both spirometric and kinematic techniques and compared to those of a group of 19 nonneurologically impaired controls matched for age and sex. Results of the spirometric assessment showed that only a minority of the Parkinson's subjects had lung volumes and capacities outside normal limits. Consequently in the majority of cases, the speech disorder could not be related to any abnormality in lung function determined spirometrically. Chest wall dynamics during both conversation and reading were essentially normal in all cases. Approximately half of the Parkinson's subjects, however, exhibited irregularities in their chest wall movements while performing vowel prolongation and syllable repetition tasks. The same irregularities were not present in the chest wall movements exhibited by the control subjects, suggesting that their presence was in some way related to the Parkinson's disease. Results are discussed in terms of the effects of Parkinson's disease on neuromuscular function.

Iterative dysarthria is a speech disorder which bears some resemblance to stuttering. It is commonly found in Parkinson's disease but has so far received little attention to. We report the case of a 67 year old female parkinsonian patient with a severe dysarthria of the iterative type. The characteristic features of iterative dysarthria are described and the relevant literature is reviewed.

Twenty-six patients with the speech disorder of Parkinson's disease received daily speech therapy (prosodic exercises) at home for 2 to 3 weeks. There were significant improvements in speech as assessed by scores for prosodic abnormality and intelligibility' and these were maintained in part for up to 3 months. The degree of improvement was clinically and psychologically important, and relatives commented on the social benefits. The use of a visual reinforcement device produced limited benefit over and above that from prosodic exercises alone, except to patients with severe speech disorder.

Interrater reliability of the Unified Parkinson's Disease Rating Scale (UPDRS) motor examination was assessed by three neurologists experienced in the administration of this scale. Intraclass correlation coefficients indicated good-to-excellent agreement for speeded repeated movements, resting tremor, arising from a chair, and gait; moderate agreement for action tremor, rigidity, posture, postural stability, and bradykinesia; and poor agreement for speech disorder and facial immobility. Overall, these results indicate that satisfactory interrater reliability is attainable with the UPDRS motor examination.

A survey of approximately 460 patients with Parkinson's disease (PD) or multiple sclerosis (MS) shows that speech and swallowing difficulties are very frequent within these groups. Seventy percent of the PD patients and 44% of the MS patients had experienced impairment of speech and voice after the onset of their disease. Forty-one percent of the PD patients and 33% of the MS patients indicated impairment of chewing and swallowing abilities. The speech disorder was regarded as one of their greatest problems by 29% of the PD patients and by 16% of the MS patients. Only a small number of patients, 3% of the PD and 2% of the MS group, had received any speech therapy.

Primary progressive aphasia is a rare disorder of unknown cause. We report a patient with progressive loss of speech output, a clinical variant of PPA, characterized by festinating speech. A 60-year-old right handed woman was admitted to our hospital, because of progressive deterioration of her speech. On admission, she was alert and orientated without dementia. A severe impairment of her articulation was observed: her speech rate was so fast that her speech became almost intelligible. The orofacial apraxia and difficulty in tapping were also present. The other neurological findings were normal. Neuroradiological studies showed the left perisylvian atrophy. Festinating speech has not been previously reported in patients with PPA; patient with PPA usually show a slow speech rate with effortful expression. Since festinating speech is occasionally present in the extrapyramidal disorders, such as Parkinson's disease, progressive supranuclear palsy, or pure akinesia, it appears likely that the combined lesions of the perisylvian region and the basal ganglia are responsible for her characteristic speech disorder with festinating speech.

Parkinson's disease is not only a disorder affecting locomotion, but often also causes speech problems. Functional impairment of articulation, phonation, prosody and also respiration may occur. Speech disorder is frequent in Parkinson's disease and often has an impact on the quality of life. Speech therapy is by no means offered as a matter of course to these patients. This article outlines the different approaches of speech therapy regarding respiration, loudness, articulation, prosody, and intonation. Speech therapy seems to be useful in patients with Parkinson's disease only if there is no cognitive impairment; success also depends on motivation and eventual frequent repetition of therapy series.

Weakness and fatigue in the orofacial system often are presumed to contribute to the dysarthria associated with neuromotor disorders, although previous research findings are equivocal. In this study, tongue strength, endurance, and stability during a sustained submaximal effort were assessed in 16 persons with mild to severe Parkinson disease (PD) and a perceptible speech disorder. The same measures were taken from one hand for comparison. Only tongue endurance was found to be significantly lower in these participants than in neurologically normal control participants matched for sex, age, weight, and height. Analyses of data from a larger sample comprising the present and retrospective data revealed lower-than-normal tongue strength and endurance in participants with PD. No significant correlations were found between tongue strength and endurance, interpause speech rate, articulatory precision, and overall speech defectiveness for the present and previously studied participants with PD, bringing into question the influence of modest degrees of tongue weakness and fatigue on perceptible speech deficits.

The laryngeal pathophysiology underlying the speech disorder in idiopathic Parkinson disease (IPD) was addressed in this electromyographic study of laryngeal muscle activity. This muscle activity was examined during voice onset and offset gestures in 6 persons in the early stages of IPD who were not receiving medication. The purpose was to determine (a) if impaired voice onset and offset control for speech and vocal fold bowing were related to abnormalities in laryngeal muscle activity in the nonmedicated state and (b) if these attributes change with levodopa. Blinded listeners rated the IPD participants' voice onset and offset control before and after levodopa was administered. In the nonmedicated state, the IPD participants' vocal fold bowing was examined on nasoendoscopy, and laryngeal muscle activity levels were compared with normal research volunteers. The IPD participants were then administered a therapeutic dose of levodopa, and changes in laryngeal muscle activity for voice onset and offset gestures were measured during the same session. Significant differences were found between IPD participants in the nonmedicated state: those with higher levels of muscle activation had vocal fold bowing and greater impairment in voice onset and offset control for speech. Similarly, following levodopa administration, those with thyroarytenoid muscle activity reductions had greater improvements in voice onset and offset control for speech. In this study, voice onset and offset control difficulties and vocal fold bowing were associated with increased levels of laryngeal muscle activity in the absence of medication.
