What are the effects of alcohol on the brain?

Metronidazole is an antibacterial agent that kills bacteria by damaging cellular DNA and hence cellular function.292 Metronidazole is usually given to people who have diarrhea caused by Clostridioides difficile bacteria. Patients who are taking metronidazole are sometimes advised to avoid alcohol, even after 1 hour following the last dose. Although older data suggested a possible disulfiram-like effect of metronidazole, newer data has challenged this and suggests it does not actually have this effect. Alternative methods of alcohol administration like alcohol enema, alcohol inhalation, vodka eyeballing, or using alcohol powder (which can be added to water to make an alcoholic beverage, or inhaled with a nebulizer), all carry significant health risks. Outbreaks of methanol poisoning have occurred when methanol is used to lace moonshine (bootleg liquor).234 This is commonly done to bulk up the original product to gain profit. Because of its similarities in both appearance and odor to ethanol (the alcohol in beverages), it is difficult to differentiate between the two.

The pharmacology of ethanol involves both pharmacodynamics (how it affects the body) and pharmacokinetics (how the body processes it). In the body, ethanol primarily affects the central nervous system, acting as a depressant and causing sedation, relaxation, and decreased anxiety. The exact mechanism remains elusive, but ethanol has been shown to affect ligand-gated ion channels, particularly the GABAA receptor.

Imbalance Leads to Anxiety and Depression

Rape is any sexual activity that occurs without the freely given consent of one of the parties involved. This includes alcohol-facilitated sexual assault which is considered rape in most if not all jurisdictions,207 or non-consensual condom removal which is criminalized in some countries (see the map below). Public-order crimes caused by drinking include drunk driving, domestic violence, and alcohol-related sexual assaults.

Seeking help from professionals who understand the complex relationship between alcohol addiction and mental health is a cornerstone for lasting recovery and sobriety. However, with these temporary stimulant effects, alcohol’s overall impact is depressant, significantly as consumption increases and its sedative effects take hold. In larger doses, alcohol causes drowsiness, sluggishness, and emotional changes like sadness or depression.

1. Blood, and therefore alcohol, is quickly distributed throughout the body and the brain.
2. Miscarriage, also known in medical terms as a spontaneous abortion, is the death and expulsion of an embryo or fetus before it can survive independently.
3. By disrupting brain chemistry and altering neuronal pathways, alcohol creates a complex cycle of dependency that requires targeted intervention.
4. If you or someone you know is battling alcohol addiction, early intervention can prevent several serious diseases.
5. In the US, alcohol is subject to the FDA drug labeling Pregnancy Category X (Contraindicated in pregnancy).

Although alcohol can have stimulating effects, it doesn’t last for long. Over time the stimulant effects will fade, and you’ll start to feel its depressant effects. Heavy drinkers experience fluctuations in levels of chemicals like GABA and dopamine in their brains. Long-term, this leads to dependence, making the brain incapable of functioning without alcohol. Evidence shows that some people can experience a more significant stimulant effect from alcohol. Many researchers believe this puts them at a higher risk of developing alcohol use disorder (AUD).

Examples include nicotine, although it’s most frequently characterized as a stimulant, and alcohol, which is primarily a depressant but has some stimulant effects (3, 4). This article reviews the effects of alcohol, both as a stimulant and a depressant. Calls to our general hotline may be answered by private treatment providers.

Alcohol alters brain chemistry by enhancing inhibitory neurotransmitters like GABA and reducing excitatory ones like glutamate, impairing cognition, judgment, coordination, and memory while increasing the risk of long-term neurological damage. If you or someone you know is battling alcohol addiction, early intervention can prevent several serious diseases.

Commercial interests contribute to drug use and addiction

This risk is especially high during alcohol intoxication because lowered sexual inhibition can make it difficult to withdraw in time. Children with fetal alcohol spectrum disorder (FASD) are at an increased risk of having hearing difficulties. The answer is more complicated than it first appears, with no obvious, true or false answer. Alcohol is technically classified as a depressant because it slows, or depresses, basic functions such as speech, reactions, and movement.

Stimulants vs. depressants

When a certain amount of alcohol had been bought, the owner of the booklet had to wait until next month to buy more. Paradoxically, despite being legal, alcohol, scientifically classified as a drug, has demonstrably been linked to greater social harm than most illegal drugs.187188 This contradicts the perception some hold of alcohol being a harmless substance. The best way to prevent this interaction is by avoiding the co-ingestion of both substances or using specific controlled-release formulations that are resistant to AIDD. Nitrous oxide has been shown to be an effective and safe treatment for alcohol withdrawal.164 The gas therapy reduces the use of highly addictive sedative medications (like benzodiazepines and barbiturates). Delirium tremens is a condition that requires people with a long history of heavy drinking to undertake an alcohol detoxification regimen. The alcohol molecules (ethanol, to be technical) that are in tequila are the same as those in whisky, wine, beer, vodka, and other liquors.

Chronic exposure to alcohol seems to alter the NMDA receptors and this may play a role in the clinical symptoms of alcohol withdrawal. In vitro studies have demonstrated an increase in the binding sites for MK801 (dizocilpine) in neurons chronically exposed to alcohol. This rise may account for the acclimation process, in which greater concentrations of alcohol are needed to cause experimental and clinical symptoms of intoxication. Mice that have been exposed to chronically elevated levels of alcohol reveal increased numbers of NMDA receptors and NMDA related seizure activity. The NMDA antagonist MK801 has been shown to decrease the severity of seizures in these mice during withdrawal.

Acetate is not carcinogenic and has low toxicity,312 but has been implicated in causing hangovers.313314 Acetate is further broken down into carbon dioxide and water and eventually eliminated from the body through urine and breath. 5 to 10% of ethanol is excreted unchanged in the breath, urine, and sweat. Research suggests that light or moderate wine consumption may reduce the risk of dementia, but drinking an excessive amount of wine increases the chance of dementia and cognitive decline. Long-term overuse of alcohol can cause physical and psychological dependence.

Addressing emotional or mental health concerns can help people with AUD find ways to cope that do not involve alcohol. Individuals with alcohol use disorder (AUD) continue to consume alcohol despite experiencing negative consequences. Although AUD cases may differ in severity, people who receive effective treatment can fully recover. The type of alcohol in alcoholic beverages is ethanol, or ethyl alcohol. Manufacturers create alcoholic drinks through a process called fermentation. Depressant effects of alcohol occur when your BAC reaches about 0.08 mg/l.

Anyone who has felt themselves getting more confident, more energetic, and less inhibited after a drink or two is well aware of the stimulating effects of alcohol. That’s because of the release of dopamine, which lessens feelings of pain and increases feelings of happiness. Alcohol’s ability to raise the heart rate also tilts it toward the stimulant category — for a while, at least.
