Summary
Most individuals with Parkinson's disease (PD) experience speech and voice disorders, yet few receive treatment. This review examines PD speech impairments, available therapies, and treatment effectiveness for better patient outcomes.
Area of Science:
- Neurology
- Speech-Language Pathology
Background:
- Parkinson's disease (PD) frequently causes speech and voice disorders affecting laryngeal, respiratory, and articulatory functions.
- An estimated 89% of individuals with PD exhibit these speech impairments.
- Despite high prevalence, only 3-4% of PD patients access speech treatment.
Purpose of the Study:
- To review the literature on speech and voice disorders in Parkinson's disease.
- To characterize the features of these disorders.
- To evaluate available treatment options and their efficacy.
Main Methods:
- Systematic literature review of studies on Parkinson's disease and speech/voice disorders.
- Analysis of medical, surgical, and behavioral therapy interventions.
- Assessment of current treatment efficacy and identification of research gaps.
Main Results:
- Speech and voice disorders are highly prevalent in Parkinson's disease.
- A significant gap exists between the incidence of speech impairment and treatment receipt.
- Various treatment modalities show potential but require further research for optimal efficacy.
Conclusions:
- Speech and voice disorders significantly impact individuals with Parkinson's disease.
- Current treatment rates are critically low, necessitating increased awareness and access.
- Further research is crucial to refine and validate effective interventions for PD-related speech impairments.
