Some have it and just don’t know. My husband has it and he didn’t know. I had to learn about it. They can be impatient and can have a hard time sitting still unless they are watching something that has action. They can be extroverted. They have a hard time sitting and listening for too long. I am sure you know this if your son has it.

My therapists wife has it and his son has it too. He is more introverted. His wife has struggled with depression. His wife has it yet has a genius IQ so it’s not indicative to lack of intellect.
