Speech and language changes in PD impact upon individual and family life long before frank impairment of intelligibility is apparent. The role of early referral to speech and language therapy is therefore worthy of detailed investigation.
the psychosocial consequences of the physical changes concerned people most. The importance of the early detection of changes for health and quality of life is underlined.
Background: Changes to spoken communication are inevitable in Parkinson's disease (PD). It remains unclear what consequences changes have for intelligibility of speech. Aims: To establish the prevalence of impaired speech intelligibility in people with PD and the relationship of intelligibility decline to indicators of disease progression. Methods: 125 speakers with PD and age matched unaffected controls completed a diagnostic intelligibility test and described how to carry out a common daily activity in an ''off drug'' state. Listeners unfamiliar with dysarthric speech evaluated responses. Results: 69.6% (n = 87) of people with PD fell below the control mean of unaffected speakers (n = 40), 51.2% (n = 64) by more than 21 SD below. 48% (n = 60) were perceived as worse than the lowest unaffected speaker for how disordered speech sounded. 38% (n = 47) placed speech changes among their top four concerns regarding their PD. Intelligibility level did not correlate significantly with age or disease duration and only weakly with stage and severity of PD. There were no significant differences between participants with tremor dominant versus postural instability/gait disorder motor phenotypes of PD. Conclusions: Speech intelligibility is significantly reduced in PD; it can be among the main concerns of people with PD, but it is not dependent on disease severity, duration or motor phenotype. Patients' own perceptions of the extent of change do not necessarily reflect objective measures.
Swallowing problems are frequent in PD. Self-report of 'no difficulty' is not a reliable indicator of swallowing ability. Studies employing more-objective assessment of aspiration risk to compare with water swallow test performance are advocated.
Chewing sugarless gum following elective intestinal resection is associated with improved outcomes. Insufficient data were available to demonstrate a reduced rate of clinical complications or reduced cost. An adequately powered, methodologically rigorous trial of gum chewing is required to confirm if there are any benefits and if these result in differences in clinical outcomes such as infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
