If you’re wondering about neurodiversity in particular, there’s a lot of research about ADHD. Here’s a recent example of a reasonably effective intervention:

Evans, S. W., Langberg, J. M., Schultz, B. K., Vaughn, A., Altaye, M., Marshall, S. A., & Zoromski, A. K. (2016). Evaluation of a school-based treatment program for young adolescents with ADHD. Journal of Consulting and Clinical Psychology, 84(1), 15–30. http://dx.doi.org/10.1037/ccp0000057

There’s a lot of recent work demonstrating strong associations between ADHD, study skills, and GPA:

Kuriyan, A. B., Pelham, W. E., Jr., Molina, B. S., Waschbusch, D. A., Gnagy, E. M., Sibley, M. H.,… Kent, K. M. (2013). Young adult educational and vocational outcomes of children diagnosed with ADHD. Journal of Abnormal Child Psychology, 41, 27– 41. http://dx.doi.org/10 .1007/s10802–012–9658-z
