“…Environmental lead problems have improved considerably since the days when Byers and Lord (1943) described cases of children who suffered life-changing impairments as a result of chewing on the railing of their cribs. Banning lead paint and leaded gasoline has greatly reduced the average American child's lead exposure.…”

This meta-analysis examined the association between conduct problems and lead exposure. Nineteen studies on 8,561 children and adolescents were included. The average r across all 19 studies was .19 (p < .001), which is considered a medium effect size. Studies that assessed lead exposure using hair element analysis yielded considerably larger effect sizes than those that assessed lead exposure using blood, tooth, or bone lead levels. Excluding the 3 hair analysis studies, the average r was .15 (p < .001). The age of the participants did not significantly moderate the relation between lead exposure and conduct problems. Overall, the relation between lead exposure and conduct problems was strikingly similar in magnitude to the relation between lead exposure and decreased IQ.

“…The association between environmental lead exposure and aggressive behavior was first described by Byers and Lord (1943) in their pioneering series of 20 cases of children who had ''recovered'' from lead poisoning. Prior to their publication, the general assumption was that successfully treated lead poisoning did not have long-term consequences.…”

The foundations of Neuropsychology lie in the fields of behavioral neuroscience, applied psychological evaluation, and behavioral neurological investigation. These areas have provided increasing sophistication about the nature of the relationship between changes in brain function and human behavior. Continuing developments in these fields will provide the foundation upon which our applied activities rest and from which they take their scientific validity. The use of neuropsychological evaluative tools as aids in understanding the consequences of subtle and, in many instances, not primarily neurological medical illnesses represents a threshold of investigation and clinical application. The sensitivity of clinical neuropsychological tools to disruptions in brain function, previously left unrecognized in individuals who have sustained neurological injury or illness, represents the second threshold issue. Yet another threshold issue is the use of neuropsychological investigation as a preventive tool and as an early warning signal for the appreciation of a broad range of risk factors encountered by individuals not typically thought of as potential patients for neuropsychologists. This article discusses the growing use of neuropsychological tools to understand the broader range of human behavioral difficulties and human medical consequences.
