Does Drinking Alcohol Kill Brain Cells?

Watch someone after they’ve had a few drinks, and you’ll find clear evidence that alcohol does something to their brain. They stumble, slur their words, lose control of their emotions, and forget things. 

Some people have tried to explain this behavior as the aftermath of cell death caused by alcohol. Often, it’s packaged as a neat factoid like “Three beers kill 10,000 brain cells.”

But is this true? No. But alcohol does damage some of your 86 billion brain cells, or neurons, which send electrical and chemical messages within the brain and between it and other parts of the body. 

Ethyl alcohol (the kind found in boozy beverages, also known as ethanol) can kill cells and microorganisms. That’s what makes it an effective antiseptic. Fortunately, when you drink alcoholic beverages, your body tries not to let all of that ethanol roam around unchecked. Enzymes in your liver convert it first info acetaldehyde (which is highly toxic) and then into acetate, which is broken down into water and carbon dioxide and eliminated by your body.

The liver can only work so fast, though, processing about 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of distilled spirits per hour. If you’re knocking drinks back fast enough that your liver can’t keep up, the excess alcohol hangs out in the blood and travels through the body until it can be processed. 

When this alcohol reaches the brain, it doesn’t kill the cells. What it does is inhibit the communication between dendrites, or branching connections at the ends of neurons that send and receive information between neurons, in the cerebellum, a part of the brain involved in motor coordination. This poor communication results in some of the typical impairments of intoxication. 

Researchers at Washington University in St. Louis found that alcohol, even when applied directly to neurons, didn’t kill them. It just interfered with the way they transmit information. Specifically, the researchers showed that alcohol causes certain receptors on neurons to manufacture steroids that inhibit memory formation. 

Some alcoholics can experience neuron death as part of a brain disorder called Wernicke-Korsakoff syndrome. In these cases, the evidence again suggests that the disease and cell death aren’t caused by the alcohol itself, but a B1 (or thiamine) deficiency and general malnutrition that often go hand in hand with alcoholism. 

For moderate drinkers, a number of studies from the last 15 years suggest that, far from killing brain cells, a little tipple is actually associated with a reduced risk of cognitive decline and dementia.

New Pop Chart Lab Poster Is a Boozy Blueprint For Making Classic Cocktails

Pop Chart Lab

Pop Chart Lab's posters combine design with data, and their latest offering—a full breakdown of the ingredients in 60 classic cocktails—is no exception. From the exact ratio of gin and tonic that should go into a G & T (2 ounces and 4 ounces, respectively) to the garnishes you'll need to make a proper Tom Collins (a maraschino cherry and a lemon twist), the 3-foot-by-2-foot "Constitutions of Classic Cocktails" artwork teaches mixology basics you'd typically learn in bartending school, sans tuition fee.

In addition to mainstays like the Negroni and the Whiskey Sour, the poster also includes relatively obscure drinks (ever heard of the Golden Dawn, or the Journalist?), which you can attempt after drinking your way through your favorite concoctions. Before you know it, you'll be explaining to your friends the intricacies of why you should stir martinis instead of shaking them (sorry, James Bond), or the difference between a highball and a Collins glass. Bottoms up!

"Constitutions of Classic Cocktails" costs $37, and is currently available for pre-order. Shipping begins on Friday, October 20, 2017. (To see the poster's details up close, visit Pop Chart Lab's website and click on the diagram.)

Beer lovers aren’t given many chances to discuss their passion for imbibing at job interviews. But a new open position at London's Meantime Brewing Company lists that expertise as one of the top qualifications. As Fortune reports, the brewery is seeking a professional beer taster to help improve its products.

The brewery’s part-time employee will “join the panel brewers as they taste, discuss, and pass opinion on a range of different beers,” according to the job listing on LinkedIn. On top of steady access to free booze three hours a week, the taster will receive a competitive salary “with beer benefits.” As the description reads: “Yes, this could just be the best job in the world.”

Meantime isn’t just considering any casual beer drinker for the role. Their ideal candidate will have a precise palate that can distinguish “chocolate malt from dark malt” and “Fuggles from Cascade hops.” They will also have an understanding of global consumer markets, a functioning knowledge of English, and an extensive beer vocabulary. The brewery is located in the London borough of Greenwich, so applicants who aren’t local should be willing to relocate.

Founded in 1999, the Meantime Brewing Company made its name on the beer scene with signature beverages like their London Lager, London Pale Ale, and Yakima Red. If you’re interested in joining the team, post 30 words on your LinkedIn profile explaining why you deserve the gig, along with any photos or videos that may help your case, with the hashtag #pickmemeantime. The company will narrow down the pool to three candidates for an in-person beer tasting before deciding their top pick. Meanwhile, you can prepare for the job by brushing up on your beer facts.
