ADHD doesn’t always look the way people expect it to.
Some people's ADHD traits show up in an external way that is easy to notice and observe, movement, impulsivity, emotional reactions, interrupting, disorganization.
Others ADHD traits are more internalized. They may appear quiet, responsible, high achieving, or “fine” on the outside while experiencing constant mental chatter, mental overwhelm, anxiety about forgetting, masking, perfectionism and exhaustion.
And many people may have bits of both, depending on the environment, sense of safety, supports available, etc.
One of my children has a much more internalized presentation of ADHD. Teachers often respond with a look of confusion and disbelief when they learn she has ADHD because she “does so well in class.”
What often gets missed is how much mental energy can go into appearing regulated, focused, organized, when those mental tasks just don't come naturally.
ADHD is not defined by how disruptive someone is to others.
When we're only looking for externalized traits, there's a whole group that's been overlooked and left with an ongoing internal struggle but no explanation for why, other than they must be a failure or not trying hard enough.
We need to develop more assessment tools and processes that include and evaluate internalized traits as well.
