Individuals with autism spectrum disorders (ASD) constitute a diagnosis characterised by a multifunctional neurocognitive disorder, based on a limited connexional structure for neuronal-synaptic functioning of the GABAergic system. This brain condition should significantly implicate the association of other comorbid disorders associated with ASD, which deepen to a nuclear diagnosis. The most significant comorbid associations found in this comparative study have been the psycho-affective components, such as the presence of anxiety, severe anxiety and depression, as well as the association of schizotypal traits and the presence of convulsive-epileptic processes in different degrees of intensity, which can be isolated or, sometimes, in interaction with each other, which enhances the symptomatology of the disorder, as well as the difficulties of the appropriate intervention plan.
