[MORE] Alcohol and Alzheimer’s

Several studies have emerged over the past year noting the sinister effects of alcohol on cognitive function. In the previous article, research from a French study revealed alcohol abuse as a prominent contributor towards dementia, with heavy emphasis on early onset Alzheimer’s specifically. But why does this happen?

A study conducted on 360 patients from New York, Boston, Baltimore and Paris discovered that the type and amount of alcohol consumed played an integral role in impacting the rate of cognitive decline. The study found that heavy drinkers, those who consumed more than eight alcoholic beverages per week were at a greater risk of a speedier decline in cognitive function as compared to moderate drinkers who consumed one to seven alcoholic beverages per week. Results of this study also indicated that increased consumption of hard liquor presented a more prominent decline, however this was not the case with beer and wine. 

In summary, heavy alcohol consumption accelerates the rate of cognitive decline in Alzheimer’s patients, indicating a strong likelihood that it precipitates the progression of the disease, thus leading to early onset Alzheimer’s.


Alcohol Use Disorder a Major Risk Factor for Dementia

A new study conducted in France analyzed the nationwide data for admitted patients in hospitals between 2008 and 2013 found that alcohol use disorders were significantly associated with dementia.

The study supports that alcohol use disorder be recognized as a major risk factor for all types of dementia, especially for early-onset dementia. The analysis also showed that the risks are remain unchanged even after abstinence from drinking, citing that lifelong damage had already been inflicted on the brain.

In their closing, the researchers recommended that the risk of alcohol use disorder should be recognized, and that appropriate action such as early detection and intervention should be taken to reduce heavy drinking, and delay or prevent the onset of dementia.
