QUESTION: Effect of lead on the brain, up to 4 yrs of age, 08 Nov 2003, England United Kingdom

I need information on the total effects of being exposed to levels of lead during pregnancy and through to the age of 4 years.

Mainly I need to know what effect it would have on the brain.

Any help would be gratefully received thank you

ANSWER: 08 Nov 2003

Dear Marie, Though your question seems simple, whole books and literally thousands of research papers have been written on the subject. It would be easier for me to answer it if you were more specific. Do you want to know for an assignment, for a legal case, because you were exposed to lead up to the age of 4 or your child was or because you or someone you know is suffering specific health effects and you want to figure out if they could have been caused by lead? Or for some other reason? A good starting point for any of these are the fact sheets "Health Impacts of Lead Poisoning - A preliminary listing of the health effects & symptoms of lead poisoning" and Lead Poisoning And The Brain - Cognitive Deficits And Mental Illness but please let me know your circumstances if you want more than this.
