E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To examine the effects of donepezil, Intensive Group Rehabilitation of Aphasia (REGIA) plus (REGIA + repetition / imitation task) and transcranial direct current anodal stimulation (A-tDCS) on the severity of language disorders and associated disorders (communication , behavior, and quality of life) secondary to lesions in the left perisylvian area in patients with chronic post-stroke aphasia. |
Examinar los efectos de donepezilo, Rehabilitación Grupal Intensiva de la Afasia (REGIA) plus (REGIA + tarea de repetición/imitación) y estimulación transcraneal de corriente directa anodal (A-tDCS) en la gravedad de los trastornos del lenguaje y trastornos asociados (comunicación, conducta, y calidad de vida) secundarios a lesiones en el área perisilviana izquierda en pacientes con afasia crónica post-ictus (ACPI). |
|
E.2.2 | Secondary objectives of the trial |
• Evaluate possible changes in cognitive non-linguistic functions (attention, short-term verbal memory and cognitive control) and its relationship with the improvement in the linguistic domain. • Examine, through the use of different neuroimaging techniques, the structural, functional and metabolic changes in the gray and white matter (tracts) and explore changes in connectivity (MRI at rest) and the biochemical markers (spectroscopy) promoted by the interventions made. • Analyze whether the microstructural integrity (tractography) of regions not damaged by stroke act as surrogate indicators of prediction of response to different treatments, which will allow a better selection of therapeutic strategies in future studies. • Evaluate if the benefits achieved in different domains are maintained in the long term (three months) after the interruption of the treatments. |
• Evaluar posibles cambios en funciones cognitivas no-lingüísticas (atención, memoria verbal a corto plazo y control cognitivo) y su relación con la mejoría en el dominio lingüístico. • Examinar mediante el uso de diferentes técnicas de neuroimagen los cambios estructurales, funcionales y metabólicos en la sustancia gris y blanca (tractos) y explorar cambios en la conectividad (RMN en estado de reposo) y los marcadores bioquímicos (espectroscopia) promovidos por las intervenciones realizadas. • Analizar si la integridad microestructural (tractografía) de las regiones no dañadas por el ictus actúan como indicadores subrogados de predicción de respuesta a los diferentes tratamientos lo que permitirá una mejor selección de estrategias terapéuticas en estudios futuros. • Evaluar si los beneficios alcanzados en diferentes dominios se mantienen a largo plazo (tres meses) tras la interrupción de los tratamientos. |
