What would it take to get researchers to expand their demographic sections to include a question about neurodiverse conditions?

If you gathered the information on neurodiverse conditions (ADD, ADHD, ASD, Bi-polar) you could publish to a broader audience on the relevance, or lack of relevance, to that growing population.

Demographic question: "Do you likely have a neurodiverse condition, such as ADD, ADHD, ASD, Bi-polar?" Would you ask this in your study?
