Mercury Linked to Alzheimer's

Inorganic mercury, which is still widely used in dental amalgams, is likely a contributing cause of Alzheimer's disease (AD) according to the November issue of the Journal of Alzheimer's Disease.

Overall, investigators found that symptoms and features of AD were reproduced or accelerated when mercury was introduced. As a result of these findings, the researchers called for "the removal of mercury from public and ecologic circuits and replacing it wherever possible by less toxic alternatives. This would be a sensible public health measure that is supported by the current data."

Of 40 studies that tested memory in individuals exposed to inorganic mercury, 32 found significant memory deficits. The study authors also note that some autopsy studies also revealed increased mercury levels in the brain tissue of AD patients.

"In vitro models showed that inorganic mercury reproduces all pathological changes seen in AD, and in animal models inorganic mercury produced changes that are similar to those see in AD," the study authors write.

Bonnie - this should not be a surprise for anyone who reads our blog consistently.
