Possible link between exposure to lead and autism in children needs exploring
Over the years, I’ve kept my eye on research that throws light on thecause of autism . In a new study, scientists say being exposed to lead while in the womb or just after being born might possibly increase a child’s chances of becoming autistic.
Lead exposure has previously been linked to cognitive problems, with some scientists accusing leaded petrol of having lowered IQ levels.
Autism is indisputably genetic. We know if your sibling has it, your chance of having it is raised tenfold. If that sibling is an identical twin, your chance of also being autistic rises to 70%.
But this isn’t the only answer, as some identical twins have different diagnoses. That’s why researchers have started looking at environmental influences before and just after birth.
