This neurotransmitter is released whenever we feel pleasure, whether it be from eating, sleeping, having sex, using the bathroom, exacting revenge, lifting weights, scoring the winning shot in your YMCA basketball league, or any other moment we consider pleasurable. Most of the entire reward system in our brain is due to dopamine. This chemical chain reaction is what causes a tolerance to alcohol. However, the more alcohol one consumes, the more GABA produced, and the more glutamate produced in order to keep the balance. Glutamate counteracts the over-calming effects of GABA. In response to increased GABA levels, the brain creates more glutamate, an excitatory neurotransmitter. This happens every time alcohol is consumed, a GABA increase, and will happen more and more intensely over time, as long as there is drinking. Essentially, the overflow causes mild sedation of the brain. Off-balance walking, slurred speech, and poor memory of time spent drinking are all results of increased GABA. If this sounds bad, that’s because it is.Īlcohol-caused increases in GABA explain why drunk people have trouble with their motor skills. Alcohol increases the flow of GABA inside the brain. Its main function is to reduce activity in the brain, such as when we are concentrating, sleeping, resting, or attempting to calm down, or even maintaining a normal overall bodily balance. Gamma-aminobutyric acid, or GABA, is the brain’s principal inhibitory neurotransmitter.

Finally, let’s talk about how to treat and/or prevent such alcohol-caused brain conditions. Then let’s discuss potential brain conditions that are caused by alcohol. Let’s take a look at how alcohol affects these three neurotransmitters. However, excessive drinking over time causes the brain to adapt to these changes.Įventually, the brain cannot function without alcohol, and we call this alcoholism. For non-problematic drinkers and for those just beginning to drink in their lives, alcohol creates pleasurable effects in the brain, which we called being buzzed or drunk. Three different types of neurotransmitters are affected in particular by alcohol: GABA, dopamine, and endorphins. Excitatory neurotransmitters speed up brain activity, allowing for focus, attention, alertness, possible unease, and nervousness.Īlcohol creates changes in the brain. Inhibitory neurotransmitters slow down overall brain activity, allowing for rest, ease, balance, peace of mind, and general calmness. There are two basic types of neurotransmitters: inhibitory and excitatory. They deliver messages that tell the body what to do. The chemicals responsible for all of this are called neurotransmitters. Movement, emotions, our five senses, thought, blinking, breathing, heartbeat, pain and pleasure are all controlled by and made possible by the brain. Every function you can think of is controlled by the brain. The brain is the control room of the body. Each neuron is responsible for tens of thousands of different connections, which enable every single thing we do. There are over 100 billion neurons in the average human brain. As you may remember from high school, all living things are made up of cells. We must first understand the basics of how the brain operates before we can understand the effects of alcohol. What are addictive are the chemical reactions that happen in our brains when ethanol is consumed. As a standalone substance, it is non-addictive. Ethanol is the type of alcohol inside of adult beverages. What we commonly call alcohol, when it comes to drinks, is actually ethanol, one of over fifteen types of alcohol.

Why is America home to 18 million alcoholics? Why is one out of every twelve American adults alcohol dependent? Why do 240 US citizens die every single day from alcohol? Why do more than 9,000 people worldwide die every single day from alcohol? Why is $250 billion spent every year on excessive alcohol consumption? Why, you may ask, have over 85% of Americans reported having drank at least once in their life? Why is a full quarter of global deaths attributable to alcohol for those between age 20 and 39?
