One of the common complications that women who have problems that seem to be related to their implants complain about has to do with concentration and memory loss. They get better when the implants are removed. The women are often in their thirties and they feel like they're in their seventies. They're having trouble concentrating, they can't remember things, they can't speak coherently. It's these kinds of neurological problems that could be related to the platinum
There is no data that compares the different generations. The platinum seems to come from the shell, not from the gel. Platinum is used to thicken silicone to make the elastomer that makes the shell. That's not the natural form of silicone. That's why it's used. Some research is under way to see whether these new gummi bear implants have more platinum; thickening the gel so much may require that you use platinum.
The amount of platinum used to make breast implants is supposed to be really microscopic--very tiny amounts. What we don't know is whether some end up having more platinum in manufacturing than they're supposed to. Perhaps that would explain why some women get very sick from breast implants and other women don't.
