Neurodivergence is a broad term rather than a diagnosis by itself.
Autism, for example, is a neurological and developmental disorder that can affect communication, interaction, learning, and behavior. Its features begin developmentally, although autism may be diagnosed at any age. If these experiences feel familiar, that recognition can be meaningful, but education cannot determine their cause. A professional evaluation can consider your developmental history, current functioning, strengths, distress, and other explanations together.
