“…In secondary analyses, we also found lower levels of tCr, tCho, and mI in the ACC of children with AS compared to controls, but no differences in the cerebellum. These results are in disagreement with the results of two prior studies in adults with AS, which reported elevations of ACC and frontal lobe NAA compared to controls [12,14]. A third prior study had measured levels of metabolites in amygdala-hippocampal complex in 10–50 years old AS, and found no significant difference compared to controls although it reported report a significant age-related reduction in NAA, NAA/Cr, and tCho in the AS group [13], suggesting potential differences in these metabolites between adults and children (vide infra).…”

“…Several prior 1 H MRS studies in ASD [10,11], and three in AS have been reported [1214]. A meta-analysis of 1 H MRS data from the ACC of children with ASD found significant decreases in the levels of the putative neuronal marker, N-acetylaspartate (NAA), compared to controls [10].…”

“…Investigaciones posteriores señalaron resultados similares en adolescentes y adultos con este síndrome (O'Brien et al, 2010;Murphy et al, 2012). Sin embargo, Toal et al (2010) y Yu et al observaron reducción de la sustancia gris en hipocampos de individuos adultos con SA en comparación con los controles.…”

“…Los trastornos del espectro autista se caracterizan por la presencia de dificultades en la interacción social derivadas de un desarrollo cerebral diferencial (Attwood, 2007). Estas diferencias se dan tanto en el nivel citoarquitectónico, involucrando áreas frontales, témporo-parietales y algunas partes del sistema límbico, como en los períodos de desarrollo cerebral, debido a diferencias en la concentración de sustancias bioquímicas en el cerebro (McAlonan et al, 2008;O'Brien et al, 2010;Thompson, Thompson y Reid, 2010) 2 . Aun cuando no hay consenso en la bibliografía, se ha planteado que, en el plano neurocognitivo, el SA se puede caracterizar por distintos problemas, enunciados en cuatro principales teorías de funcionamiento cognitivo.…”

“…En los últimos años se ha desarrollado una gran cantidad de estudios sobre el lenguaje en personas con SA (Atwood, 2007;Ghaziuddin y Gerstein, 1996;Hadjikhani, 2007;Happé, 1999;Kaland et al, 2002;Shriberg et al, 2001;Le SournBissaoui et al, 2009;Lewis, Murdoch y Woodyatt, 2007;Loukusa y Moilanen, 2009;McAlonan et al, 2008;O'Brien et al, 2010;Pijnacker, Hagoort, Buitelaar, Teunisse y Geurts, 2008;Rivière y Castellanos, 2003;Segura, 2007;Thompson et al, 2010;Valdez, 2005). Estas investigaciones han mostrado que, si bien parecen presentar una morfosintaxis y una semántica normales (pero cfr.…”
