Read what polygenic risk scores mean https://www.genome.gov/Health/Genomics-and-Medicine/Polygenic-risk-scores

I haven't read the whole document I referred to above yet, but what it treats was genetic propensities to certain traits, and which of said traits are being selected for or against. Whether environment will compensate for something is wholly another matter.

If individuals with ADHD have constantly higher reproductive success, as the source indicates, this simply means more individuals will likely develop said disorder. I don't remember whether autism was listed in the graph, but anyone knows anyway that autists have very poor reproductive chances these days. Just bringing a comparison between two mental illnesses.

Also, I wouldn't like to jump into Caamib's territory, but last decades really show intelligence is being selected against. There's a collection of materials here: https://incels.is/threads/irrefutable-proof-of-the-hypergamy-and-why-the-current-mode-of-sexual-selection-is-dysgenic.396281/
