So this might be old news but Spencer Shay from iCarly is definitely ADHD coded and this is the hill I'll die on. It's especially highlighted in the episode where Carly wishes for Spencer to be normal, implying his personality is something to be fixed (much how people view ADHD and other neurodiversities).
Impulsiveness, has periods of hyperfocus/hyperfixation, and saying wildly inappropriate things at the wrong times (I know it's played as a joke but it could be read as misinterpreting social cues) could all be signs of ADHD (or another kind of neurodivergence).
