You want the official answer or the somewhat more “woke” answer?

Technically, it doesn’t. Neurodivergent is a broad umbrella that means a number of different disorders. Including, but not limited to, autism, attention deficit hyperactivity disorder (ADHD), bipolar disorder, developmental prosopagnosia, developmental speech disorders, dyslexia, dysgraphia, dyspraxia, dyscalculia, dysnomia, intellectual disability, Fetal Alcohol Syndrome Disorder (FASD), obsessive–compulsive disorder (OCD), sensory processing disorder, synesthesia, Tourette syndrome, and more.

Why do most people THINK it only means Autism and ADHD? They tend to get more media attention.

The “woke” bit is Autism and ADHD have been historically “male coded” disorders, while things like Bipolar, OCD, etc. were either female coded or gender neutral in popular culture. For a long time they didn’t even think women could have Autism or ADHD.

I for one don’t want to pretend I didn’t benefit from more pearl clutching over people’s “perfect baby boys” being a little atypical neurologically. I did, and it’s silly to pretend I didn’t. Also as one of the “Flagship” neurodivergences, I’m also more likely to end up in a MAHA gas chamber to “Purify the Gene Pool”, so there’s both upsides and downsides to penis-privilage, but at least people care which is more than some other spectra get.
