There is no single test to diagnose ADHD, and many other diagnoses, like anxiety, depression, and certain types of learning disabilities, can have similar symptoms and even overlap with ADHD.
We like to think about ADHD like this:
It’s not that a child with ADHD cannot pay attention. It is that he/she has extreme attention and is paying attention to EVERYTHING. The trouble is focusing on the task at hand.
When consulting professionals to determine if your child has ADHD, the following criteria from the Diagnostical Statistical Manual V are considered.
