About Attention Deficit / Hyperactivity Disorder (AD/HD): ADHD is a highly genetic, brain-based syndrome that has to do with the regulation of a particular set of brain functions and related behaviors. These brain operations are collectively referred to as “executive functioning skills” and include important functions such as attention, concentration, memory, motivation and effort, learning from mistakes, impulsivity, hyperactivity, organization, and social skills. There are various contributing factors that play a role in these challenges including chemical and structural differences in the brain as well as genetics.
