What is Attention Deficit Disorder Definition
These disorders are occasionally a result of environmental stress.
Most cases, however, are felt to have a biological basis.
Attention deficit disorders should be differentiated from mental retardation, schizophrenia, or a manic-depressive state.
The onset is before the age of 7 years, and an estimated 5 percent of school-aged children exhibit characteristics of some form of learning disorder.
I.Q. tests taken by these children are normal, and there are no neurologic abnormalities.
Attention deficit disorders may result in poor school performance.
In some cases, there are specific learning disabilities, such as visual-motor or speech defects.
