The neuropsychology of multiple sclerosis.

Abstract: Multiple sclerosis (MS) is the most common cause of neurological disability in young and middle-aged adults in the United States and Europe. The etiology of MS is still unclear, although evidence suggests a cell-mediated immune response to myelin antigens triggered by a viral infection in genetically predisposed individuals. 1,2 MS generally follows a variable course affecting spinal and cerebral myelin, resulting in problems with coordination, vision, fatigue, weakness, tremor, bladder or bowel control, balance, cognitive impairment, dysarthria, dysphasia, and depression. 3,4 Of the primary symptoms of MS, cognitive impairments are among the most devastating. The most commonly found impairments in MS patients include attention, information processing, memory, visual perception and construction, and abstract reasoning, whereas recognition memory, gen

Incorporating the Principles of Self-Management into Treatment of Dysarthria Associated with Parkinson's Disease.

Abstract: Although understanding patient perspectives on treatment is a major component of patient-centered care, little is known about patient perspectives related to dysarthria treatment in Parkinson's disease (PD). This article attempts to explore the perspective of patients with dysarthria associated with PD by interviewing them before and after treatment. Treatment expectations and experiences are summarized along with a discussion of how patients are using the tools they learned once treatment was completed. Comments about treatment were generally positive and suggested increased awareness and improved speech loudness. However, areas for improvement were also identified including: (1) treatment was not addressing some communication problems that were of concern to patients; (2) therapy programs were not enjoyable; and (3) it was difficult to maintain gains after therapy ended. Principles of self-management are reviewed to address some of the shortcomings of current treatment approaches.

Development of a voice-input voice-output communication aid (VIVOCA) for people with severe dysarthria

Abstract: This paper describes an approach to the development of a voice-input voice-output communication aid (VIVOCA) for people with disordered or unintelligible speech, initially concentrating on people with moderate to severe dysarthria. The VIVOCA is intended to recognize and interpret an individual's disordered speech and speak out an equivalent message in clear synthesized speech. User consultation suggests that such a device would be acceptable and would be useful in communication situations where speed and intelligibility are crucial. Speech recognition techniques will build on previously successful development of speech-based home control interfaces, and various methods for speech 'translation' are being evaluated.

Modeling listener perception of speaker similarity in dysarthria.

Abstract: The current investigation contributes to a perceptual similarity-based approach to dysarthria characterization by utilizing an innovative statistical approach, multinomial logistic regression with sparsity constraints, to identify acoustic features underlying each listener's impressions of speaker similarity. The data-driven approach also permitted an examination of the effect of clinical experience on listeners' impressions of similarity. Listeners, irrespective of level of clinical experience, were found to rely on similar acoustic features during the perceptual sorting task, known as free classification. Overall, the results support the continued advancement of a similarity-based approach to characterizing the communication disorders associated with dysarthria.
