DC. 2000. Parallels between attention deficit hyperactivity disorder
and behavioral deficits produced by neurotoxic exposure in monkeys.
Health Perspectives 108 (suppl 3):405-408.
Attention deficit hyperactivity disorder (ADHD)affects between 3
and 7% of children in the United States, and in some the condition
persists throughout their lives. In this paper Rice summarizes several
of the key characteristics of ADHD in people and compares these

lead and PCBs.

and execute tasks in an efficient or sensible temporal sequence."
short attention span: "an inability to persist in the face
of distracting or competing stimuli."
in the ability to adjust behavior to past experience: "a
