ADHD (attention deficit hyperactivity disorder) is defined as a neurobehavioral development disorder that normally starts during early childhood.
Fact 1. Based on the 2003 estimates from the Center for Disease Control and Prevention (CDC), in the U.S. there is an estimated 4.4 million children ranging from ages 4-17 have been diagnosed with ADHD. Â
Fact 2. Â ADHD patients normally have an inattentive disposition, lack in organizational skills, and find taking instructions a challenge.
Fact 3.   They are also hyperactive and impulsive. Smaller children tend to be constantly jumping, running, and climbing. Restless and impulsive, they are more prone to injuries and accidents.
Fact 4. ADHD patients can be either inattentive, hyperactive, or possess both characteristics.
Fact 5. Food additives have been suspected of triggering ADHD in children. The European Union ruled in 2008 that synthetic food colorings, especially azo dyes, must contain warnings of possible adverse effects on activity and attention in children.
Fact 6. Studies have also shown that mercury exposure during pregnancy could trigger ADHD-related behaviors. This could impact the consumption of fish during pregnancy as some fish are known to contain a relatively large level of mercury.
Fact 7. ADHD is diagnosed more often in boys as compared to girls.
Fact 8. ADHD is a lifelong, chronic condition that could potentially lead to drug and alcohol abuse, low performance in academic studies or sustaining a career as well as following rules and regulations.
 Fact 9. The causes for ADHD can range from hereditary, genetic, head injuries, poor nutrition, substance abuse, and exposure to toxins during childhood.
Fact 10. East Asian countries have comparatively lower rates of ADHD diagnosed mainly due to cultural backgrounds including the belief in philosophies such as Confucianism. Additionally, the cultural values of a high education, living in harmony and loyalty to parents are significant traits which could potentially be a deterrent towards the occurrence of ADHD.

Academic difficulties are also frequent. The symptoms are especially difficult to define because it is hard to draw a line at where normal levels of inattention, hyperactivity, and impulsivity end and clinically significant levels requiring intervention begin. To be diagnosed with ADHD, symptoms must be observed in two different settings for six months or more and to a degree that is greater than other children of the same age.
