Alcohol and GABA | Does Alcohol Increase GABA?

Alcohol impacts the brain in many ways. Some of these changes are temporary and relate to intoxication and other effects of alcohol. Others associated with chronic, excessive alcohol use can change the brain in a more permanent way.

One area where people frequently have questions is the relationship between alcohol and GABA, and whether or not alcohol increases GABA.

The following provides an overview of the relationship between alcohol and GABA, and answers the question “does alcohol increase GABA?”

Alcohol and GABA | Does Alcohol Increase GABA?
GABA is a neurotransmitter that works to block certain impulses fired between nerve cells in the brain. Low levels of GABA are associated with things like chronic pain, epilepsy, anxiety and other mood disorders. There is a theory that one of the roles of GABA is to produce a relaxing effect on the nervous system. When people have lower than normal levels of GABA in the brain, they can be linked with sleep disorders and schizophrenia. As a result, people will sometimes try to use GABA as a supplement in an attempt to improve sleep and mood and relieve symptoms of anxiety. Despite the fact that people do try to take GABA as a supplement, medical professionals and researchers aren’t certain that ingesting it this way allows it to actually reach the brain.When someone takes a prescription medicine that’s in the benzodiazepine class of drugs, like Valium or Ativan, it binds to the same receptors as the natural neurotransmitter GABA. That’s why these drugs have a calming effect.So, what is the link between alcohol and GABA, and does alcohol increase GABA?
The relationship between alcohol and GABA is somewhat complex, and in some ways, alcohol and GABA have similar effects on the brain. This is because alcohol is an agonist of GABA receptors. This means that alcohol binds to certain GABA receptors in the brain, where it replicates the activity of the GABA neurotransmitter. So, does alcohol increase GABA? No, alcohol doesn’t increase GABA, but it does act on the brain in a similar way.Alcohol has a depressive effect on the central nervous system because it binds to certain GABA receptors. That’s why most people feel relaxed and even tired after drinking. While alcohol doesn’t increase GABA, it does increase the amount of serotonin and dopamine released in the brain. Even drinking a little bit of alcohol will increase the amount of serotonin and dopamine in your brain and stimulate certain reward centers. This is why people feel pleasurable effects when they drink. The interaction of alcohol and GABA receptors, as well as the relationship between alcohol and serotonin and dopamine, explains why people feel a sense of well-being when drinking. Many of the ways alcohol affects the brain are similar to other depressants because most depressants work by binding to GABA receptors.When you drink a small amount, you obviously will often only see the positive effects of alcohol. But when you drink too much, you what can overstimulate GABA pathways, which can lead to extreme sedation of the central nervous system. This can cause alcohol toxicity and overdose. Alcohol affects many other areas of the brain, but understanding how alcohol and GABA together can explain many of alcohol’s pleasurable and dangerous effects. Continued exposure to alcohol over time can desensitize the GABA receptors. This may cause chronic drinkers to feel more stress, which, in turn, may make them want to drink more often. This leads to building a tolerance to alcohol, and the development of dependence and addiction over time. It also explains why people experience alcohol withdrawal symptoms when they attempt to stop drinking. Their brains may become overstimulated and unable to regulate GABA on their own, triggering withdrawal symptoms once they become sober.So, does alcohol increase GABA? No, but alcohol binds to the same receptors as GABA, producing a similar effect. Understanding the relationship between alcohol and GABA is important when considering alcohol dependence and addiction. Drinking large amounts of alcohol over time can cause desensitized GABA receptors, increasing chances of developing an alcohol use disorder.
