Deterioro cognitivo leve: detección temprana y nuevas perspectivas

Abstract

Introduction. Along past years, interest in mild cognitive impairment (MCI) research and its early detection has been increased. Unlike first theories, international current proposals suggest that MCI is a syndrome characterized by an impairment in one or more cognitive functions without interfering in daily functional abilities and it is also accompanied by a concern because of the cognitive change. Although early MCI detection is usually made by cognitive screening tests, most of them do not seem to correctly detect MCI, but dementia. Aim. To expose an analysis of the cognitive screening tests more suitable for clinical MCI detection, according to current researches. Development and conclusions. There are three kind of cognitive screening tests: general cognitive screening tests, specific cognitive screening tests and MCI-subtype cognitive screening test. We observe that most of the tests don't follow current MCI criteria. In this respect we propose to jointly apply tests, as well as the necessity of a carefully test choice to effectively detect MCI in clinical practice.

Electrophysiological Correlates of Amnestic Mild Cognitive Impairment in a Simon Task

“…Sets of neuropsychological tests that commonly include (among other aspects) evaluation of memory functions do not usually show higher sensitivity and specificity values than those observed in the present study for N2pc (0.77 and 0.76 sensitivity and specificity, respectively) and LRP amplitude (0.80 and 0.92 of sensitivity and specificity, respectively) (for reviews see Lonie et al, 2009 [80] ; Mora-Simón et al, 2012 [81] ). Therefore, the present investigation may represent a first step in establishing N2pc –in sdaMCI- and/or LRP-r –in sdaMCI and mdaMCI- amplitudes as early biomarkers of amnestic MCI.…”

Análisis del Test de Actitudes Alimentarias (EAT-26) con un modelo tipo Rasch en una muestra de adolescentes paraguayos.

“…En la evaluación de los TCA, son indispensables las pruebas de cribado. Cabe anotar que la inalidad de estas pruebas es facilitar la detección de manifestaciones provocadas por la alteración de alguna función superior mediante escalas de fácil y rápida aplicación (Mora-Simón et al, 2012). La disponibilidad de estos instrumentos en la clínica le permitiría al psicólogo tener una idea general de la situación del paciente.…”

Factores predictores de deterioro cognitivo en población mayor de 64 años institucionalizada y no institucionalizada

“…Este no es el caso del presente estudio, pues nuestro centro es considerado como residential home, en los cuales entre los criterios de ingreso está precisamente el de no padecer limitaciones físicas o mentales que requieran suplencia o ayuda. La prevalencia de DC encontrada en no institucionalizados se encuentra dentro del rango establecido en otros estudios y que oscila entre el 3 y el 53% 21 .…”
