AD(H)D=Attention Deficit (Hyperactivity) Disorder, a condition where a child is extremely active, restless, breaks things for no reason and will not concentrate on learning. These children have the attention and ability to process information, but with too many outside impulses the child is not able to decide which ones are more important than others and will thus become confused when reacting to a normal everyday situation.
This inadequate self control results in an impairment of mental information reception, transmission and processing and this can also lead on to developmental disorders, body perception delays, impulsiveness, aggression, partial disturbances of performance because of diminished cognetive abilities and learning problems.
