Adult male monkeys exposed to cocaine while in the womb have poor impulse control and may be more vulnerable to drug abuse than female monkeys, even a decade or more after the exposure, according to a new study by researchers at Wake Forest University School of Medicine. The findings could lead to a better understanding of human drug abuse.

Research has shown that diabetes increases the risk of Alzheimer’s disease and the risk of memory loss in people who don’t have Alzheimer’s disease. But it hasn’t been clear whether people with Alzheimer’s disease and diabetes have more rapid memory loss than those who have Alzheimer’s disease but no diabetes. New research published in "Neurology" suggests that those with both diseases actually have a slower rate of memory loss than people who had only Alzheimer’s disease.
