The Autism Long-term Outcomes Study (ALTOS) examined adolescents and young adults who were diagnosed with autism early in development according to gold standard expert clinical evaluation, who currently have no symptoms. In prior work, we described the unique brain networks that were involved in language processing in such a population, in comparison with individuals with a current autism diagnosis and those without a history of autism. This talk will describe results of our current behavioral and fMRI studies of language outcomes and their association with other cognitive and communication abilities as well as mental health and quality of life.
