Late Diagnosis Awareness Day

A day raising awareness of the experience of being diagnosed autistic in adulthood. Late diagnosis is increasingly common, particularly among women, gender-diverse people, and people from marginalized communities who were missed by diagnostic systems designed for young white boys.

History

Late Diagnosis Awareness Day emerged from autistic community advocacy. The late diagnosis experience — with its mix of relief, grief, anger, and clarity — has gained significant visibility through social media and first-person accounts.
