REDUCING LEAD EFFECTS
ANCHOR LEAD: IT MAY BE POSSIBLE TO REVERSE MOST EFFECTS OF LOW LEVEL LEAD EXPOSURE, ELIZABETH TRACEY REPORTS
Even low levels of lead can damage the brain, especially in children. Tomas Guilarte, a lead expert at Johns Hopkins, says developing understanding of how lead exacts damage may help identify treatments.
GUILARTE: It is important to understand the way lead produces effects in the brain because then we can test different approaches from a therapeutic standpoint to see whether we can mitigate the effects of lead and brain function. One of the ways we’re looking at has to do with brain stimulation in the form of environmental enrichment, and also we’re beginning to examine whether exercise, which is a way to stimulate neurogenesis in the brain, could also be beneficial. :26
Guilarte says both exercise and games that require thinking and reasoning may both work by increasing blood flow, and therefore oxygen to the brain while stimulating new neuron growth. I’m Elizabeth Tracey reporting.
