Speech rhythm alterations in Spanish-speaking individuals with Alzheimer’s disease

Abstract: Rhythm is the speech property related to the temporal organization of sounds. Considerable evidence is now available for suggesting that dementia of Alzheimer's type is associated with impairments in speech rhythm. The aim of this study is to assess the use of an automatic computerized system for measuring speech rhythm characteristics in an oral reading task performed by 45 patients with Alzheimer's disease (AD) compared with those same characteristics among 82 healthy older adults without a diagnosis of deme… Show more

“…Each row corresponds to the filter response of one recording. As described in [32], the increase in the power of low frequency ranges can be a result of cognitive decline. The high values and main differences are concentrated in the first several filters for the three tasks.…”

“…La alteración del lenguaje es una de las manifestaciones más destacadas y tempranas de la Enfermedad de Alzheimer (Schröder, Wendelstein & Felder, 2010). Las investigaciones más recientes han demostrado que el deterioro del lenguaje en EA es integral y afecta todos los niveles del sistema lingüístico y sus manifestaciones: la fonética segmental y suprasegmental (Mesulman, Rogalski, Wieneke, Hurley, Geula, Bigio, Thompson & Weintraub, 2014;Martínez-Sánchez, Meilán, Vera-Ferrandiz, Carro, Pujante-Valverde, Ivanova & Carcavilla, 2017); el nivel léxico y el nivel semántico (Szatloczki, Hoffmann, Vincze, Kálmán & Pakaski, 2015;Lima Silagi et al, 2015); la gramática y la sintaxis (Ahmed, de Jager, Haigh & Garrard, 2012;Ivanova, 2015); así como la construcción del discurso (Pistono, Jucla, Barbeau, Saint-Aubet, Lemesle, Calvet, Köpke, Puel & Pariente, 2016). Dentro de este cuadro de afectación lingüística compleja, las alteraciones léxico-semánticas ocupan un lugar destacado, tanto por su mayor evidencialidad en la expresión verbal de los hablantes como por su papel central en la caracterización del lenguaje en EA.…”
