I understand this is something being researched. but it’s not something conclusive. there are a few studies suggesting links but more work needs to be done. there’s studies in there that are out of date and others that rely on self-reported symptoms. then there’s also comorbid ASD which muddies the water. one great study you link controlled for ASD and found interesting things to follow up on, but you cannot base conclusions on one paper alone.

as far as the science is currently concerned, sensory sensitivity is not diagnostic of ADHD at this time. and with OP saying they have ASD, why even lump ADHD in this?

I’m getting so tired of armchair psychologists on social media, jeez…
