Science Update: Hormone may underlie link between childhood abuse and adult cognitive decline, NIH-funded study finds.
Researchers funded by the National Institutes of Health have linked elevated levels of an immune system hormone to the adult cognitive decline that often occurs in people who experienced abuse as children. The hormone, interleukin-6 (IL-6), is involved in the swelling or inflammation produced in response to an injury. The researchers also found that child abuse victims who have a history of depression are more likely to experience cognitive decline as adults.
