Recently, based on voice cepstral analysis, Benba et al. (IEEE T. Neur. Sys. Reh., vol. 24, pp. 1100-1108, 2016) have reported discrimination between patients with Parkinson's disease and different neurological disorders with high classification accuracy up to 90%. Using the same approach, we were able to experimentally separate two groups of normal healthy(More)
OBJECTIVE Patients with idiopathic rapid eye movement sleep behaviour disorder (RBD) are at substantial risk for developing Parkinson's disease (PD) or related neurodegenerative disorders. Speech is an important indicator of motor function and movement coordination, and therefore may be an extremely sensitive early marker of changes due to prodromal(More)
Heat and moisture exchangers (HMEs) have been used for more than 30 years for heat and moisture retention during general anesthesia. Studies about bacteriostatic vs nonbacteriostatic HMEs (BHMEs/NHMEs) have been conducted to assess their role in preventing bacterial transmission to the anesthesia breathing circuit; none have been done on anesthetized(More)
Speech rhythm abnormalities are commonly present in patients with different neurodegenerative disorders. These alterations are hypothesized to be a consequence of disruption to the basal ganglia circuitry involving dysfunction of motor planning, programing, and execution, which can be detected by a syllable repetition paradigm. Therefore, the aim of the(More)
For generations, the evaluation of speech abnormalities in neurodegenerative disorders such as Parkinson's disease (PD) has been limited to perceptual tests or user-controlled laboratory analysis based upon rather small samples of human vocalizations. Our study introduces a fully automated method that yields significant features related to respiratory(More)
