Yes. Pretty much all the symptoms of ADHD are things that everyone experiences from time to time. People with ADHD just experience them far, far more often, in a way that often negatively impacts their career and relationships. And their lives tend to get better after being diagnosed, as they can start using meds and learning ADHD-specific organisation strategies.
Sure. It's just that the rest of the time people without ADHD can sit still for longer than ten minutes and don't uncontrollably interrupt people while talking.
Is this not a normal occurrence? I thought this is just how it is for everyone when they encounter a problem that captivates them.
