Speaking a Second Language May Delay Dementia

People who speak more than one language and who develop dementia tend to do so up to 5 years later than those who are monolingual, according to a study.

A team of scientists examined almost 650 dementia patients and assessed when each one had been diagnosed with the condition. The study was carried out by researchers from the University of Edinburgh and Nizam's Institute of Medical Sciences in Hyderabad (India).

They found that people who spoke two or more languages experienced a later onset of Alzheimer's disease, vascular dementia and frontotemporal dementia.

Study of Twins Shows How Smoking Ages the Face

A study comparing the faces of identical twins confirms what many smokers fear -- the habit does prematurely age a person's skin, taking a serious toll on looks even after just five years.

Researchers from Case Western Reserve University in Ohio used the annual Twins Day Festival in Twinsburg, Ohio, to identify 79 pairs of twins in which one sibling smoked and the other didn't.

The twins who were smokers showed many more signs of skin aging, the researchers found. Their faces featured more wrinkles, creases, droops and jowls.

"Smoking harms virtually every organ in the body, including your skin," said Danny McGoldrick, vice president for research at the Campaign for Tobacco-Free Kids. "Whether you are doing it for vanity or your health, one of the most important health decisions of your life is not to start smoking, or to quit if you have."
