16-year-old Niamh McCann is passionate about many things including ballet, the plays of William Shakespeare, the environment and public speaking! Her talk looks at the challenges of the high-functioning end of the Autistic Spectrum for girls. Niamh is a quiet, sensitive girl who studied hard, got good grades and was not one to cause trouble. She researched the reasons why girls on the spectrum are often misdiagnosed or have late diagnoses. Her hope is that through her talk and sharing what she has learnt, all girls on the spectrum will feel freer to embrace who they are and that those who are yet to be diagnosed are not afraid to do so. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
