Large, high quality research has found small differences in the brain between ADHD and non-ADHD patients. [1] [15] Jonathan Leo and David Cohen, critics who reject the characterization of ADHD as a disorder, contended in 2003 and 2004 that the controls for stimulant medication usage were inadequate in some lobar volumetric studies, which makes it impossible to determine whether ADHD itself or ...
Attention deficit hyperactivity disorder; Other names: Formerly: Attention deficit disorder (ADD), hyperkinetic disorder (HD) [1]: ADHD arises from maldevelopment in brain regions such as the prefrontal cortex, basal ganglia and anterior cingulate cortex, which regulate the executive functions necessary for human self-regulation.
A survey conducted by the Centers for Disease Control and Prevention in 2011–2012 found 11% of children between the ages of 4 and 17 were reported to have ever received a health care provider diagnosis of ADHD at some point (15% of boys and 7% of girls), [182] a 16% increase since 2007 and a 41% increase over the last decade.

Attention deficit hyperactivity disorder predominantly inattentive (ADHD-PI or ADHD-I), [3] is one of the three presentations of attention deficit hyperactivity disorder (ADHD). [4] In 1987–1994, there were no subtypes or presentations and thus it was not distinguished from hyperactive ADHD in the Diagnostic and Statistical Manual (DSM-III-R).
People with classic ADHD are more likely to be rejected in these situations because of their social intrusiveness or aggressive behavior. Compared to children with CDS, they are also much more likely to show antisocial behaviours like substance abuse, oppositional-defiant disorder or conduct disorder (frequent lying, stealing, fighting etc.). [18]
Attention deficit hyperactivity disorder (ADHD) A disorder characterized by problems sustaining attention, hyperactivity, or acting impulsively. [26] Dyslexia and ADHD commonly occur together. [5] [27] [28] Approximately 15% [10] or 12–24% of people with dyslexia have ADHD; [29] and up to 35% of people with ADHD have dyslexia. [10] Auditory ...
The prevalence of ADHD within the age group of 5-11 years for both male and female children is 8.6%, whereas children in the age group of 12-17 years is 14.3%. [ 37 ] This difference between genders may reflect either a difference in susceptibility or that females with ADHD are less likely to be diagnosed than males. [ 38 ]
[2] [5] As public awareness of ADHD has increased, epidemiological studies have found a prevalence rate of 4–12% in children of ages 6–12 throughout the United States. Not only is ADHD the most commonly encountered childhood-onset disorder in neurodevelopment, there is also a high comorbidity rate linking ADHD with other behavioral ...
