This reinforcement of positive feelings makes alcohol particularly addictive for some individuals. When alcohol enters the brain, it stimulates the release of dopamine in the nucleus accumbens, a critical part of the brain’s reward system. This surge of dopamine produces the feelings of pleasure and euphoria that can accompany drinking. However, this effect is temporary, leading many people to drink more in an attempt to sustain the dopamine high. When you kick the habit and start living sober, your brain begins a long process of regaining balance. The recovery of dopamine levels isn’t an overnight fix; it takes time and consistent effort.

Dopamine release was altered in a sex-dependent manner in chronic alcohol self-administering macaques

To date, there are three medications approved by both the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) for the Alcoholics Anonymous treatment of alcohol dependence; disulfiram, naltrexone and acamprosate. More recently, the EMA granted authorization also for nalmefene, a compound intended for the reduction of alcohol consumption in adults with alcohol dependence (EMA 2012). Details regarding the mechanism of action of these compounds are outside the scope of this review. An indirect activation of mesolimbic dopamine via accumbal glycine receptors and ventral tegmental nicotinic acetylcholine receptors (nAChRs) appears likely 2, 3, but additional targets has been suggested (for review see 4).

The Truth About Dopamine After Alcohol Addiction Recovery

However, the relationship between alcohol and dopamine is complex and often misunderstood. While alcohol initially increases dopamine levels, chronic alcohol use can lead to long-term changes in the brain’s dopamine system. Over time, the brain may become less sensitive to dopamine, requiring more alcohol to achieve the same pleasurable effects. This phenomenon, known as tolerance, is a key factor in the development of alcohol dependence. The mesocorticolimbic dopamine system (or the so‐called brain reward system, Figure 1) is one of the established neurobiological systems involved during the development and maintenance of alcohol dependence and thus one potential treatment target.

• Detoxification is an essential first step, helping to cleanse the body of alcohol toxins and restore harmony to the brain’s chemical balance.
• On the other hand, aripiprazole did not interfere with the alcohol‐induced impairment in motor balance as measured by rotarod test 179.
• These results are largely in agreement with the literature, though some disparities exist.
• Thus, the number of 5-HT2 receptor molecules and the chemical signals produced by the activation of this receptor increase in laboratory animals that receive alcohol for several weeks.

Dopamine’s Dual Effect: Neurotransmitter and Hormone

Stress management techniques such as meditation, deep breathing exercises, or yoga can help reduce cortisol levels, which can interfere with dopamine function. The timeline of dopamine recovery in the first weeks of sobriety can be challenging. While some improvement may be noticeable within days, significant changes in dopamine function often take weeks or even months.

Neuroscience: The Brain in Addiction and Recovery

Despite this knowledge, relatively little is known about the mechanisms by which this occurs. Therapeutic restoration of cognitive control of behavior has the promise of reducing the rate of relapse and improving quality of life in individuals who suffer from alcohol-use disorders. In addition to its effects on intrinsic excitability, acute ethanol can also modulate GABAergic transmission and disinhibit DA neurons in the VTA. Since elevated levels of DA are observed in areas like the NAcc and PFC following ethanol exposure, one possibility is that DA neurons in the VTA are disinhibited from tonic control over their firing by GABAergic neurons in this region. Ethanol has different effects on GABAergic transmission in the VTA depending on which cell population is assessed, with some GABAergic neurons showing enhanced firing and others reduced firing (Xiao & Ye, 2008).

Dopamine: The pathway to pleasure

The neurons then store the dopamine in small compartments (i.e., vesicles) in the terminals of their axons. When the dopaminergic neurons are activated, the resulting change in the electrical charges on both sides alcohol and dopamine of the cell membrane (i.e., depolarization) induces dopamine release into the gap separating the neurons (i.e., the synaptic cleft) through a process called exocytosis. The DA system seems to be differently impaired during the development and persistence of AUD. In total, challenge studies (acute alcohol or psychostimulant administration) seem to be more consistent in their findings and might be less prone to the effects of confounders. Long-term studies with larger samples are required to better evaluate the alterations during chronic consumption and prolonged abstinence.

MDMA’s Impact on the Brain: Neurotransmitters, Effects, and Potential Risks

This reduced dopamine response could explain why individuals with alcohol use disorders often report needing to drink more to achieve the desired effects. It may also contribute to the difficulty many people face in quitting alcohol, as they may struggle to experience pleasure from other activities due to altered dopamine function. As a person regularly consumes alcohol, their brain adapts to its presence, leading to tolerance. This means that over time, more alcohol is needed to achieve the same dopamine release and subsequent pleasurable effects. Tolerance can significantly alter the relationship between alcohol consumption and dopamine release, potentially contributing to increased drinking and risk of addiction. Many substances that relay signals among neurons (i.e., neurotransmitters) are affected by alcohol.
