ADHD can be a difficult diagnosis to understand for many people and some have even questioned its validity saying it does not exist. ADHD is very real. It is true that it is often overly diagnosed and that people who do not have it often seek out the use of stimulants in high school or college. However, it is clear based on fMRIs and other cognitive neuroscience tests that it can be seen affecting the brain in many ways. ADHD is a neurological childhood-onset disorder that is caused by certain neurons not firing enough, not being active enough, and neurotransmitters not being transported from neuron to neuron. Concentration, self-control, planning, concept of time, and social skills are often areas of weakness or vulnerabilities for folks with ADHD.
