I am an almost 60-year-old autistic woman who can navigate the world in a way that surprises some people when they find out I have autism. My teen years were spent in an institution because people did not know what to do with my “behaviors” or with me. Today I am a self-employed author, speaker, consultant and artist with a master’s degree in Social Work. Question: Did I lose my autism diagnosis? Official Answer: Yes and No No, an Autism Diagnosis Cannot Be “Lost” Technically, once a person is diagnosed with anything that diagnosis becomes part of their medical records.
