After my diagnosis with ADHD, we wondered if my wife might also have it, albeit milder than mine, as she struggled with a lot of the same things I do. She went for the full neuropsych eval, and was actually diagnosed with Sensory Processing Disorder, not ADHD. So I'm not surprised to see some overlap there.
But that person was actually diagnosed with "Sensory Processing Disorder".
I'm glad that people are more aware of ADHD and because of that receive proper medication. On the other hand the symptoms of ADHD can be very similar to other disorders. Many neurological problems overlap and someone having a dysfunction in one area could also have a dysfunction in others.
So to all commenters in here, be aware that a label of ADHD may only be a part of the full picture.
