What is different in the ADHD/ADD brain?

The ADHD brain structure is different:
  • It is smaller, has less volume in some brain regions and has less cortical thickness
The ADHD brain functions differently:
  • Less activation of networks needed for executive function and attention
  • Excessive activation of networks causing hyperactivity and impulsivity
The ADHD brain has problems with some pathways:
  • The -- neurotransmitters dopamine and norepinephrine -- brain pathways are not working well.
