Attention-Deficit/Hyperactivity Disorder (ADHD) is generally considered to be a developmental disorder, largely or entirely neurological in nature effecting 3-5 percent of the population.[1][2][3][4] It is characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity[5] ADHD initially appears in childhood and manifests itself with symptoms such as hyperactivity, forgetfulness, poor impulse control, and distractibility.[6] ADHD is currently considered to be a persistent and chronic syndrome for which no medical cure is available. While the majority of ADHD is believed to be genetic in nature, roughly about 1/5 of ADHD is thought to be acquired after conception due to brain injury either parentally or postnatal due to toxins or physical trauma.According to a majority of medical research in the United States, as well as other countries, ADHD is today generally regarded to be a non-curable for which, however, some effective treatments are available. A wide body of evidence has shown that stimulant medication is the most effective way to treat the disorder.[7][8] Methods of treatment usually involve some combination of medication, psychotherapy, and other techniques. Some patients are able to control their symptoms over time, without the use of medication. Within society, there is some skepticism if a diagnosis denotes a genuine impairment or disability. The symptoms of ADHD are not as profoundly different from normal behavior as is often seen with other mental disorders. Still, ADHD has been shown to be impairing in life functioning in several settings and many negative life outcomes are associated with ADHD.ADHD is most commonly diagnosed in children and, over the past decade, has been increasingly diagnosed in adults. It is believed that around 60% of children diagnosed with ADHD retain the disorder as adults.
