The Long-Term Effects of Alcohol on the Brain: How One Sip Can Cause Permanent Damage

Researchers say alcohol can permanently alter your brain. 

Several studies have established the detrimental effects of alcohol on your body. From increasing your risk of liver cirrhosis and liver cancer to raising your chances of stroke and diabetes, alcohol can cause irreversible damage to your body. 

Though most of these studies have concluded that occasional drinking is not that damaging, recent studies have found that even one sip of alcohol can permanently alter your brain. It can change the grey matter composition and even cause neurological changes.

One sip of alcohol can permanently alter your brain – Research

Most scientific research has focused on the effects of chronic alcohol consumption. However, a research team found that even a single sip of alcohol can permanently alter the morphology of brain neurons. It changed the synapses and the dynamics of mitochondria. The results of this study also concluded that even a single consumption event can lay the foundation for alcohol addiction. The lasting neuronal changes in the brain can trigger sporadic drinking and chronic alcohol abuse. 

The details of this study revealed that alcohol exposure affected the brain’s reward system. It further stated that the first exposure to alcohol sparked disturbances in the balance between synapses in neurons. Neurons are the information messengers in the brain. The neurons create the brain’s positive association with alcohol. 

The first sip of booze can lead to addiction – Study

Several studies have found that first alcohol intoxication at an early age is a critical risk factor that can lead to alcohol addiction or alcohol use disorder at later stages. Brain scans have shown that intoxication can cause lasting changes in how the neurons communicate. The same study also revealed that it can affect the process of learning and memory. 

How Alcohol Impacts the Brain?

The effect of alcohol on your body is well-established. It is quickly absorbed through the lining of your stomach and reaches your bloodstream. From there, it spreads into the tissues throughout your body. It takes only 5 minutes for the alcohol to reach your brain and starts affecting the brain within 10 minutes. 

The body treats this intoxication as poisonous and directs all the energy toward metabolizing it. Within 20 minutes of consumption, the liver starts processing this alcohol. But during this process, all the other systems are put on hold, including your digestion. 

Your whole body absorbs alcohol, but it takes a huge toll on the brain. Alcohol interferes with the neurons and associates it with a rewarding feeling. Alcohol intoxication also affects the way your brain processes information.

Alcohol consumption can shrink your brain

According to a 2021 study, heavy drinking could lead to a loss of brain volume. It affects the grey matter volume of your brain. Researchers also found that a single sip of alcohol consumption could lead to alcohol use disorder. Another research found that people with alcohol use disorder have less grey matter. The portion of the brain affected by alcohol is responsible for skills like attention, language, memory, and reasoning. 

By altering the brain’s structure, alcohol can lead to poor memory and impaired judgment. Several studies confirmed that alcohol can impact memory. Heavy drinking can also speed up memory loss and cognitive decline. 

Alcohol can cause Cell Death and Brain Damage

Alcohol consumption can lead to greater damage to the brain and the rest of the body. Several studies have found that alcohol kills cells and damages cellular networks in the brain. Though some of these cells can be regenerated over time, some of the damage can be permanent. In cases of severe alcoholism, you might experience early onset of dementia. Further research has also shown that alcohol misuse can lead to permanent brain damage.

Your Takeaway!

Drinking alcohol has become a part of our lifestyle today. Be it a night out with friends or partying at the club, the youth cannot simply do without a glass in their hand. But this new-age habit is the root cause of many modern diseases, starting from insomnia to stress to chronic metabolic disorders. So, if you wish to live a life free from the clutch of alcoholism, it’s better to stop that first sip. Emerging research confirms that just the first sip of alcohol can alter your brain permanently.
