A Drink A Day May Delay Dementia
|Written by Administrtor|
In people with mild cognitive impairment, up to one drink of alcohol a day may slow their progression to dementia, according to a study published in the May 22, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology. Mild cognitive impairment is a transitional stage between normal aging and dementia that is used to classify people with mild memory or cognitive problems and no significant disability.
Researchers evaluated alcohol consumption and the incidence of mild cognitive impairment in 1,445 people. They then followed 121 people with mild cognitive impairment and their progression to dementia . The participants, age 65 to 84, were part of the Italian Longitudinal Study on Aging and were followed for three-and-a-half years.
The study found people with mild cognitive impairment who had up to one drink of alcohol a day, mostly wine, developed dementia at an 85 percent slower rate than people with mild cognitive impairment who never drank alcohol.
"While many studies have assessed alcohol consumption and cognitive function in the elderly, this is the first study to look at how alcohol consumption affects the rate of progression of mild cognitive impairment to dementia ," said study authors Vincenzo Solfrizzi, MD, PhD, and Francesco Panza, MD, PhD, with the Department of Geriatrics at the University of Bari, in Bari, Italy. "The mechanism responsible for why low alcohol consumption appears to protect against the progression to dementia isn't known. However, it is possible that the arrangement of blood vessels in the brain may play a role in why alcohol consumption appears to protect against dementia . This would support other observations that drinking moderate amounts of alcohol may protect the brain from stroke and vascular dementia ."
The study did not find any association between higher levels of drinking, more than one drink per day, and the rate of progression to dementia in people with mild cognitive impairment compared to non-drinkers.
The study was supported by the Italian Longitudinal Study on Aging and by AFORIGE, an Italian association for aging research.

Red Wine May Lower Lung Cancer Risk
|Written by Administrator|
Moderate consumption of red wine may decrease the risk of lung cancer in men, according to a report in the October 2008 issue of Cancer Epidemiology, Biomarkers and Prevention¸ a journal of the American Association for Cancer Research.
“An antioxidant component in red wine may be protective of lung cancer, particularly among smokers,” said Chun Chao, Ph.D., a research scientist at Kaiser Permanente Department of Research and Evaluation in Pasadena, California.
Chao analyzed data collected through the California Men’s Health Study, which linked clinical data from California’s health system with self-reported data from 84,170 men aged 45 to 69 years. Researchers obtained demographics and lifestyle data from surveys computed between 2000 and 2003, and identified 210 cases of lung cancer.
Researchers measured the effect of beer, red wine, white wine and liquor consumption on the risk of lung cancer. Adjustments were made for age, race/ethnicity, education, income, body mass index, history of chronic obstructive pulmonary disease or emphysema, and smoking history.
Among the study participants, there was on average a two percent lower lung cancer risk associated with each glass of red wine consumed per month. The most substantial risk reduction was among smokers who drank one to two glasses of red wine per day. The researchers reported a 60 percent reduced lung cancer risk in these men. Researchers warned men to stop smoking as the best way to reduce lung cancer risk; noting that even men who drank one to two glasses of red wine per day still face higher lung cancer risk than do non-smokers.
No clear associations with lung cancer were noted for consumption of white wine, beer, or liquor. “Red wine is known to contain high levels of antioxidants. There is a compound called resveratrol that is very rich in red wine because it is derived from the ...
