Autism in the Twentieth Century: An Evolution of a Controversial Condition

Abstract

Autism spectrum disorder (i.e. autism) is clinically conceptualised as a lifelong neurodevelopmental condition diagnosed by examining impairments in communication, social interaction, and a rigidity in thinking. The twentieth century was an important one for autism as it was labelled and classified during this time, along with a rise of many different voices and perspectives regarding its classification as a psychiatric disability. On one hand, great advancements have been made in terms of understanding the condition, the aetiology, and treatments, and on the other, there has been a rise of critical thinking and political issues for the inclusion agenda. This chapter discusses these movements and changes in thinking.
