Attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD) are neurological conditions characterized by developmentally unbalanced levels of attention, concentration, activity, distractibility, and impulsivity. Glucose is the brain’s main source of energy. With ADD and ADHD, brain regions that normally inhibit impulses and control attention utilize less glucose; this decreased activity in the brain leads to inattention.
Iron and Zinc deficiency cause abnormal activity in the brain which is another implication of ADD/ADHD in children. Also, children with ADD/ADHD may have low levels of certain fatty acids (including EPA and DHA) in their bodies. Most ADD/ADHD cases are identified by age 6 in children.
