Dopamine Addiction: A Guide to Dopamine’s Role in Addiction
Dopamine is a precursor (forerunner) of adrenaline and a closely related molecule, noradrenalin. Alcohol addiction and dependence of late has been shown to be affected by the influence of genes. The presence of such genes does not confirm whether a person will turn into an alcohol addict, but there is a high correlation amongst carriers of such genes and alcohol addiction. Dopamine is a neurotransmitter primarily involved in a circuit called the mesolimbic system, which projects from the brain’s ventral tegmental area to the nucleus accumbens. This circuit affects incentive motivation, i.e., how an organism reacts to incentive changes in the environment. It has been around for thousands of years and has been known for its many stimulating and mind altering effects.
Striatal activation to monetary reward is associated with alcohol reward sensitivity
This will kick up dopamine production, Peterson explains, and you’ll get a mental health boost that lasts. If you’re overindulging in certain dopamine-producing activities like sex, technology, or gambling, you’ll want to take intentional breaks, but if you’re having trouble concentrating, feeling unmotivated or tired, then you’ll want to take steps to try to increase your dopamine production. When you have a dopamine disorder, you may experience a decline in neurocognitive functions, which relates to your memory, attention, and problem-solving abilities. Into Action Recovery Centers takes pride in providing a high level of treatment and a holistic approach to recovery for those who suffer from addiction. Our comfortable facility is designed with the client’s needs foremost in mind. Our staff includes master’s level counselors, licensed chemical dependency counselors, 24-hour nursing professionals, a staff psychiatrist, a staff chef, and direct care personnel.
- Beyond the NAc, chronic alcohol exposure has varied effects on dopamine release that are brain region and species dependent.
- When you have a dopamine disorder, you may experience a decline in neurocognitive functions, which relates to your memory, attention, and problem-solving abilities.
- Two key neurotransmitters that interact with the serotonergic system are gamma-aminobutyric acid (GABA) and dopamine.
- A series of experiments in outbred rats show that the dopamine stabilizer OSU6162 attenuates several alcohol‐mediated behaviours including voluntary alcohol intake, alcohol withdrawal symptoms and cue/priming‐induced reinstatement of alcohol seeking in long‐term drinking rats [196].
- Over time, dopamine production decreases once your tolerance goes up, meaning you may need more alcohol to feel the same boost over time.

We are also thankful to the members of the Sara Jones laboratory at Wake Forest University and the Laboratory does alcohol trigger dopamine for Integrative Neuroscience at NIAAA for their support and helpful discussions.

2. Atypical dopamine D2 receptor antagonists
This study showed that microinjection of either quinpirole or quinelorane, into the anterior part of the VTA dose‐dependently decreased alcohol, but not sucrose, intake in alcohol‐preferring rats [142]. In support are the data showing that local administration of cabergoline into the VTA reduced alcohol‐seeking behaviour in rats [170]. These data are contradictory to the findings showing that the dopamine D2 receptor antagonist into the anterior VTA did not alter alcohol intake in high‐alcohol‐preferring rats [142].
Serotonin is another neurotransmitter that is affected by many of the drugs of abuse, including cocaine, amphetamines, LSD and alcohol. Raphe nuclei neurons extend processes to and dump serotonin onto almost the entire brain, as well as the spinal cord. Serotonin plays a role in many brain processes, including regulation of body temperature, sleep, mood, appetite and pain. Problems with the serotonin pathway can cause obsessive-compulsive disorder, anxiety disorders and depression. Serotonin also modulates the behavioral response to unfairness.[48] Most of the drugs used to treat depression today work by increasing serotonin levels in the brain.[49] The image below, shows, the regions of the brain where serotonin reaches [Figure 3].
