Because that is only one symptom. And there are many different reasons why people could behave that way (even on a regular basis). It neither has to be ADHD nor any other mental health problem at all.

I wish more people would see that society holds us up to an in-humane standard and many people "fail" when compared to that standard.

When more than half of all people suffer from some type of mental health issue it's quite obvious something with the system is wrong and not with us.

ADHD encompasses a variety of debilitating symtopms that are consistently present from the beginning of someone's lives. Otherwise it can't be ADHD.

It's a cheap way to deal with our system-issues to brainwash people into believing somehow their brains are wrong.
