The aim of this retrospective study was to retrace the trajectories and long-term outcomes of individuals with autism in France, and to explore the family experiences. Data obtained from parents enables us to follow the trajectories of 76 adults. Two-thirds of adults with severe autism had a very poor outcome. Those with moderate autism had a better outcome. In adulthood, the majority were in residential accommodation. None were living independently. The trajectories of people with Asperger syndrome or high-functioning autism were more positive since all of them attended school for a long time and some went to university. All of them had a good outcome but they remained dependent on aging parents who had few available supports.
