Abstract:VARIABILITY COGNITIVE PROFILE IN CHILDREN AND ADULTS WITH DOWN SYNDROME. A NEUROPSYCHOLOGICAL STUDYIntroduction: Down syndrome (DS) is a chromosomal disorder that has a specific and highly complex cognitive and behavioral phenotype. Objectives: To study the degree of variability cognitvo profile through neuropsychological diagnostic tests into two distinct developmental ages : aulta school age and older . Participants and Methods: 105 subjects aged child and adult , 43 with and 62 without SD SD were studied. Neuropsychological variables were assessed . Comparative study of different neuropsychological variables between SD and comparison groups was performed , and between groups of children and adults. Results: Children and adult SD neuropsychological performance groups had significantly (p < 0.05) lower than the control groups . 84% of the neuropsychological variables studied in child SD group showed a significant degree of variability ( p < 0.05 ) in the SD group showed adult 44% of the studied variables with a significant degree of variability. Conclusions: The neuropsychological performance in all cognitive deficit in study areas with different levels of representation according to cognitive function, and with a high degree of cognitive variability, especially in childhood.Keywords: Down syndrome , neuropsychology , cognitive variability , intellectual disability, childhood , adulthood.Resumen:Introducción: El síndrome de Down (SD) es una alteración cromosómica que presenta un fenotipo cognitivo y conductual específico y de una gran complejidad. Objetivos: estudiar el grado de variabilidad del perfil cognitvo a través de pruebas de diagnóstico neuropsicológico en dos edades claramente diferenciadas del desarrollo: edad escolar y edad aulta. Participantes y métodos: Se estudiaron 105 sujetos de edad infantil y adulta, 43 con SD y 62 sin SD. Se valoraron variables neuropsicológicas. Se realizó estudio comparativo de las diferentes variables neuropsicológicas entre los grupos SD y comparación, y entre los grupos infantiles y adultos. Resultados: Los grupos SD infantil y adulto presentaron un rendimiento neuropsicológico significativamente (p<0.05) más bajo que los grupos control. El 84% de las variables neuropsicológicas estudiadas en el grupo SD infantil mostraron un significativo grado de variabilidad (p<0.05), en el grupo SD adulto apareció un 44% de las variables estudiadas con un significativo grado de variabilidad. Conclusiones: El rendimiento neuropsicológico en deficitario en todas las áreas cognitivas estudiadas con diferente grado de representación según la función cognitiva, y con un alto grado de variabilidad cognitiva, especialmente en la edad infantil.Palabras clave: síndrome de Down, neuropsicología, variabilidad cognitiva, discapacidad intelectual, edad infantil, edad adulta.
