A comparison of brain activation patterns during covert and overt paced auditory serial addition test tasks
Forn, Cristina; Ventura Campos, Mercedes; Belenguer Benavides, Antonio; Belloch, Vicente; Parcet, Maria Antonia; Avila, Cesar Wiley (2008-06)The Paced Auditory Serial Addition test (PASAT) is a sensitive task for evaluating cognitive impairment in patients with diffuse brain disorders, such as multiple sclerosis patients. Brain areas involved in this task have ... -
Anatomical and functional differences between the Paced Auditory Serial Addition Test and the Symbol Digit Modalities Test
Forn, Cristina; Belenguer Benavides, Antonio; Belloch, Vicente; Sanjuán Tomás, Ana; Parcet, Maria Antonia; Avila, Cesar Psychology Press (2010)The Paced Auditory Serial Addition Test (PASAT) and the Symbol Digit Modalities Test (SDMT) are generally used to detect cognitive impairments in multiple sclerosis patients. Although both seem to be sensitive to the slow ... -
Análisis crítico de los estudios de neuroimagen en relación con el rendimiento cognitivo en pacientes con esclerosis múltiple
Cruz Gómez, Álvaro Javier; Belenguer Benavides, Antonio; González Rosa, Javier J.; Simón Gozalbo, Ana; Forn, Cristina Viguera (2011)El estudio y comprensión del deterioro cognitivo en los pacientes de esclerosis múltiple (EM) resulta esencial para entender esta enfermedad. El uso de las técnicas de neuroimagen puede aportar datos a la comprensión de ... -
Cambios estructurales y funcionales del hipocampo en pacientes con esclerosis múltiple y su relación con procesos de memoria
Cruz Gómez, Álvaro Javier; Belenguer Benavides, Antonio; Martínez Bronchal, Beatriz; Fittipaldi Márquez, María Sol; Forn, Cristina Viguera editores (2016-01)Introducción. Una de las alteraciones cognitivas más prevalentes en los pacientes con esclerosis múltiple son los proble- mas de codificación de la información (tanto verbal como visual), proceso relacionado con el ... -
Gray matter atrophy is associated with funcional connectivity reorganization during the Pasat Auditory Serial Addition Test (PASAT) execution in Multiple Sclerosis (MS)
Baltruschat, Sabina Anna; Ventura Campos, Mercedes; Cruz Gómez, Álvaro Javier; Belenguer Benavides, Antonio; Forn, Cristina Elsevier (2015-06)Background and purpose: We explored the relationship between gray matter atrophy and reorganization of functional connectivity in multiple sclerosis patients during execution of the Paced Auditory Serial Addition Test ... -
Hippocampal dysfunction is associated with memory impairment in multiple sclerosis: A volumetric and functional connectivity study
González Torre, Julio Alberto; Cruz Gómez, Álvaro Javier; Belenguer Benavides, Antonio; Sanchis-Segura, Carla; Avila, Cesar; Forn, Cristina SAGE Publications (2017)BACKGROUND: Previous studies have suggested a relationship between neuroanatomical and neurofunctional hippocampal alterations and episodic memory impairments in multiple sclerosis (MS) patients OBJECTIVE: We examined ... -
Increased regional gray matter atrophy and enhanced functional connectivy in male multiple sclerosis patients
Sanchis-Segura, Carla; Cruz Gómez, Álvaro Javier; Belenguer Benavides, Antonio; Fittipaldi Márquez, María Sol; Avila, Cesar; Forn, Cristina Elsevier (2016-09)Evidence suggests that sex/gender is an important factor for understanding multiple sclerosis (MS) and that some of its neuropathological consequences might manifest earlier in males. In the present study, we assessed gray ... -
Information-processing speed is the primary deficit underlying the poor performance of multiple sclerosis patients in the Paced Auditory Serial Addition Test (PASAT)
Forn, Cristina; Belenguer Benavides, Antonio; Parcet, Maria Antonia; Avila, Cesar Taylor & Francis (2008)The aims of this study were to determine which cognitive domains are evaluated by the Paced Auditory Serial Addition Test (PASAT) and to identify which of them are responsible for the poorer performance displayed by multiple ... -
Regional Brain Atrophy and Functional Connectivity Changes Related to Fatigue in Multiple Sclerosis
Cruz Gómez, Álvaro Javier; Ventura Campos, Mercedes; Belenguer Benavides, Antonio; Avila, Cesar; Forn, Cristina Public Library of Science (2013)Fatigue is one of the most frequent symptoms in multiple sclerosis (MS), and recent studies have described a relationship between the sensorimotor cortex and its afferent and efferent pathways as a substrate of fatigue. ... -
