 Diagnosis Grandin was not formally diagnosed with autism until her adulthood. As a two-year-old, the only formal diagnosis given to Grandin was "brain damage", a finding finally dismissed through cerebral imaging at the University of Utah by the time she turned 63 in 2010. While Grandin was still in her mid-teens, her mother chanced upon a diagnostic checklist for autism . After reviewing the checklist, Grandin's mother hypothesised that Grandin's symptoms were best explained by the disorder and was later determined to be an autistic savant, but a formal diagnosis consistent with being on the autism spectrum was made only when Grandin was in her forties.
