Autism- TEA

AUTISM – ASD

The Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) classifies Autism Spectrum Disorder (ASD) within neurodevelopmental disorders. Alterations are characterized, generally, by difficulties in social interactions, in verbal and non-verbal communication, and in the existence of inappropriate behaviors such as, for example, self-stimulation.

ASD seems to begin in very early stages of brain development. However, the most obvious signs tend to emerge between 2 and 3 years of age. In addition, ASD shows different manifestations for each person, both at the level of severity and in combination of symptoms. There is such a large repertoire of skills and characteristics that no two people behave in the same way.

Currently, the indicators of ASD can be measured at early ages (18 months). We professionals have three screening instruments for very early ages that have been published and validated:

-          Checklist for Autism in Toddlers (CHAT) (Baron-Cohen, et al., 1992; 1996).

-          Autism Screening Questionnaire (Berument, et al, 1999).

-          Screening test for Autism in Two Year Olds (Stone et al, 2000).
