The scientific study of the causes of developmental disorders involves many theories. Some of the major differences between these theories involves whether environment disrupts normal development, if abnormalities are pre-determined, or if they are products of human evolutionary history which become disorders in modern environments (see evolutionary psychiatry).

Attention deficit hyperactivity disorder (ADHD) [1] is a neurodevelopmental disorder characterized by executive dysfunction occasioning symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally-inappropriate.
These scores are standardised as T-scores by comparing them to the results of children within the same age group. T-scores can also be converted into percentile ranks. When the T-scores are less than 60, it means your child is in the normal range, however when the scores are above 60, there is possibility of behavioural issues.
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 ...
ADHD is the same condition in children and adults, but it can present differently in grown-ups, says Joshua M. Langberg, PhD, a licensed clinical psychologist in the Rutgers Graduate School of ...
This meant up to 10% of children in the U.S. were described as having ADHD. Current estimates suggest that ADHD is present internationally in about 7.2% of children. [33] ADHD is diagnosed around 5 times more often in boys than girls. Reasons for this disparity are debated, but likely involve both biological and social/diagnostic factors.
Normally when being compared to one another, mental age (MA) is not taken into consideration. There still may be differences in developmentally delayed (DD) children vs. typical development (TD) behavioral, emotional and other mental disorders. When compared to MA children there is a bigger difference between normal developmental behaviors overall.
Environmental factors, such as the mother smoking or drinking during pregnancy is connected to children with ADHD. Children exposed to lead at a young age will also have an increased chance of developing ADHD. Brain injuries could cause ADHD, yet only a small number of children diagnosed fit into this category.
