A new study is adding to evidence that having diabetes increases the risk of Alzheimer's disease. The five year study of more than 800 Catholic nuns and priests finds a 65% higher risk of Alzheimer's among those with diabetes compared with study subjects who did not have the disease. Diabetes is a risk factor for a form of dementia caused by poor circulation and a number of studies have suggested it also increases the risk of Alzheimer's. Researchers say this new study in the May issue of Archives of Neurology will help them better understand the impact of diabetes on the aging brain. In the meantime, they believe that controlling blood sugar levels may help reduce the risk of Alzheimer's and other memory problems.
An estrogen-activating enzyme may help explain why female smokers are more susceptible to lung cancer. Researchers at Fox Chase Cancer Center in Philadelphia found that an enzyme called CYP1B1 is present at 13 times the expected rate when smoke is introduced into a woman's lungs. And that enzyme activates a form of estrogen naturally produced in the body, but they say more study is needed to confirm an estrogen link to lung cancer.
