Aspergers and Identical Twins
Question Out of curiosity, is Aspergers relatively common amongst twins who have been affected by TTTS before birth, specifically the 'donor' sibling? I was thinking of the link with oxygen starvation being the common denominator. Many thanks, by the way love the website/emails!! Answer For those who may not know, TTTS is a disease of the placenta. In a normal multiple birth pregnancy, some blood vessels are shared between the babies and blood flow between them is equal. One minute one baby will act like a donor, the next it will act as a recipient. In a pregnancy with TTTS, for some reason, the blood flow isn't equal between the babies. One baby will always be the donor and the other always the recipient. This causes one baby to be larger than the other. Having said this, there is no solid research currently that suggests a link between TTTS and Autism Spectrum Disorders. However, new research with rats suggests that “oxygen deprivation” (one byproduct o
