[Characteristics of attention in children with attention deficit hyperactivity disorder (an analytical review)].

The information concerning specific features of different attention components (alertness, sustention and selectivity) in children with attention deficit hyperactivity disorder (ADHD) is analyzed and systematized. According to the data reviewed, behavioral and attention problems described as ADHD are not homogeneous. Literature analysis of attention characteristics in children with ADHD shows that different components can be disrupted if ADHD is diagnosed as inattentive or combined subtype, but the main deficit in this case is that of selective voluntary attention. In case of hyperactivity/impulsivity subtype of ADHD, attention is impaired mainly in its brain activation components.
