Caffeine Aids Golden Girls' Mental Health

Although wine may improve with age, the human body tends to falter during the so-called golden years. Among the most exasperating declines occur in memory and critical aspects of reasoning. However, downing plenty of caffeine-rich coffee—or
tea—may offer one low-cost solution for keeping aging wits sharp, a French study finds. The rub: This strategy appears to benefit only women.Karen Ritchie of the French National Institute of Health and Medical Research (abbreviated in French as INSERM) in Montpellier and her colleagues recruited more than 7,000 men and women—all 65 and older—from the cities of Bordeaux, Dijon, and Montpellier. All took a battery of tests to measure how nimble their minds were. Then 2 and 4 years later, each study volunteer still living took the tests again.

Alcoholism : A Widespread Problem

Excessive habitual consumption of alcoholic beverages despite physical, mental, social, or economic harm (e.g., cirrhosis, drunk driving and accidents, family strife, frequently missing work). It is usually considered an addiction and a disease. The causes are unclear, but there may be a genetic predisposition. Alcoholism occurs in about 4.2% of adults in the U.S. It is more common in men, but women are more likely to hide it. Treatment may be physiological (with drugs that cause vomiting and a feeling of panic when alcohol is consumed; not an effective long-term treatment), psychological (with therapy and rehabilitation), and/or social (with group therapies). Group therapies such as Alcoholics Anonymous are the most effective treatments. Suddenly stopstopping heavy drinking can lead to withdrawal symptoms, incl. delirium tremens.
