It’s a complex subject hindered by lack of research and, frankly, a lot of prejudice.
The more I learn, the more I suspect it’s not that “the presentation” of ADHD changes magically as you age, it’s that people who grew up with it are neurologically shaped by having to compensate for so long under adverse conditions.
I recently read about a study attempting to establish a noninvasive treatment that stimulates under-active brain regions in kids to see if it can have a positive long term effect.

In the second phase, a subgroup of children with ADHD participated in a randomized, sham-controlled trial combining cognitive training with transcranial random noise stimulation (tRNS), a painless, non-invasive form of electrical brain stimulation. The researchers targeted frontal brain regions involved in attention and self-control. After ten sessions, children who received active stimulation showed a significant reduction in the atypical brain signal, along with improvements in task performance. Importantly, some of the neural effects persisted 3 weeks after the intervention ended.
Food for thought, eh?
