Having a drink from time to time will not cause problems to the nervous system. It is a risk when the consumption is excessive, fast and repetitive, even though it’s only on weekends.

In addition, constant consumption of alcohol during the weekends may cause alcoholic dependence in adulthood.

Effects of alcohol on the brain- Consequences

1. Effects of alcohol on the brain: Excessive ingestion of alcohol affects your hippocampus

The hippocampus is a fundamental structure for memory and learning. Alcohol reduces its volume drastically affecting these cognitive processes

In addition, there are also alterations in the prefrontal cortex, which is responsible for governing self-control of our behavior.

Alcohol alters the functional development of the cerebellum, the cerebral cortex, the nucleus accumbens, prevents new synapses, and may even lead to brain death.

2. Effects of alcohol on the brain: Weekend drinking can damage your memory

A study from the University of Compostela by Dr. Cadaveira established that young people who drink alcohol intensively have worse memory and difficulty recognizing faces than those who do not drink. 

Working memory is responsible for keeping important data in our brain so we can plan and complete a task. This study also found evidence that working memory also suffers alterations, making it difficult to retain information. 

3. Effects of alcohol on the brain: Why do I have mental gaps after a night out?

After a long night of margaritas and gin tonics, you wake up with a monumental hangover, all of the symptoms included, headache, nausea and worst of all a worrying feeling of not remembering what happened last night.

This is called alcoholic amnesia or blackouts and it happens when there is an interruption in hippocampus tasks. When we drink excessively and very fast, we hinder or inhibit hippocampus receptors that transmit glutamate, necessary for the synapses between neurons. Inhibiting the memory tasks the hippocampus needs in order to remember. 

Probably when you suffer this kind of “brain blackout”, you are able to do very basic routines, undress and go to bed, send a WhatsApp, etc. but your brain is temporarily unable to create new memories.

These blackouts are dangerous, they can put you in situations of vulnerability and risk. If you are a woman, you are more likely to suffer from these alcoholic amnesias. Studies claim that we have less gastric dehydrogenase, an enzyme responsible for diluting and dissolving alcohol in our body.

Although there is no correlation between social drinkers and alcoholics when it comes to blackouts, presence, and frequency, it is recommended that if it has ever happened to you, drastically decrease your alcohol consumption.

4. Effects of alcohol on the brain: Arrival of emotional disturbances

Alcohol abuse, although intermittent, correlates with diseases and disorders such as depression, anxiety symptoms, aggression, and stress. If you are suffering from any of these symptoms, reflect on how much alcohol you ingest and look for help.

5. Effects of alcohol on the brain: Big impact on adolescent brains.

The US is number 25 in alcohol consumption around the world. Although the legal age is 21, underage drinking is still a big issue, starting around 12 years old. This data is alarming and so are the consequences. Teens generally do not drink on a daily basis, but on weekends they binge drink.

Binge-drinking in young children since their brain is still forming have terrible consequences in learning and memory capacity as well as depressive and impulsive behaviors.
