The link was even stronger in people with diabetes. While the study showed a link between the use of some artificial sweeteners and cognitive decline, it did not prove that they were a cause.
The artificial sweeteners examined in the study were aspartame, saccharin, acesulfame-K, erythritol, xylitol, sorbitol and tagatose.
