- Abstract
Aim. The aim of this article is to assess fMRI activation during semantic tasks in adolescents with ASD. Material. 44 right-handed male adolescents aged 12-19 (mean 14.3 ± 2.0), 31 with autism spectrum disorder who met DSM-IV-TR criteria for Asperger syndrome and 13 neurotypical adolescents matched according to age and handiness. Method. Functional testing (fMRI) was performed during semantic decisions tasks and control phonological decisions in three categories of tasks: concrete nouns, verbs with multiple meanings, words describing states of mind, as a control condition. Statistical analyzes were performed at the level of p <0.05 with FWE (family-wise error) correction and p <0.001. Results. In the ASD group, lower BOLD signal was demonstrated in many brain areas (including the precuneus, the posterior cingulate gyrus, the angular gyrus, the parahippocampal gyrus) regardless of task category and processing method. The smallest differences in semantic processing were found for concrete nouns and the greatest ones for words describing states of mind. Conclusions. The presence of different activation patterns in the ASD group suggests that far more than just the areas of the CNS traditionally attributed to language processing are involved in semantic deficits in ASD.
