The main neurotransmitter systems affected by alcohol are gamma-aminobutyric acid (GABA), glutamate, dopamine and opioid (Nutt, 1999). The action of alcohol on GABA is similar to the effects of other sedatives such as benzodiazepines and is responsible for alcohol’s sedating and anxiolytic properties (Krystal et al., 2006). Some people may be more prone to addiction because they feel less pleasure through natural routes, such as from work, friendships, and romance. Their genetic makeup inclines them to develop such personality traits as thrill-seeking.
How Does Addiction Develop in the Brain?
- For most people who are alcohol dependent the most appropriate goal in terms of alcohol consumption should be to aim for complete abstinence.
- Medications also can help deter drinking during times when individuals may be at greater risk of a return to drinking (e.g., divorce, death of a family member).
- Although alcohol dependence is defined in ICD–10 and DSM–IV in categorical terms for diagnostic and statistical purposes as being either present or absent, in reality dependence exists on a continuum of severity.
- People have been drinking more during the pandemic and it may be impacting you more than you realize.
Studies show that repeated use of a substance (or an activity), encouraged by a surge in dopamine, creates changes in the wiring of the brain—and those changes are reversible after drug use stops. Depressive agents such as sedatives and tranquilizers are widely used medically to combat stress, anxiety, and sleep disorders, but NIDA reports that 3.5 to 5 percent of the population uses tranquilizers and sleeping pills nonmedically. There are no substances (or activities) that universally or uniformly cause people to become addicted. And the vast majority of people exposed to most substances (or activities) considered addictive do not in fact develop addiction to them. Rather, a very complex array of cultural factors, social factors, and situational factors mingle with psychological factors, biological factors, and even personal values to influence the possibility of addiction. This complex web of consequences illustrates why mental health is a central focus in alcohol recovery programmes.
Health problems caused by alcohol dependence
Of the residential programmes, 45% provide inpatient medically-assisted alcohol withdrawal and 60% provide residential rehabilitation with some overlap between the two treatment modalities. The alcohol withdrawal programmes are typically of 2 to 3 weeks duration and the rehabilitation programmes are typically of 3 to 6 months duration. Alcohol can, temporarily at least, reduce the symptoms of anxiety and depression, leading to the theory that alcohol use in this situation is a form of ‘self-medication’.
What Increases the Risk for Alcohol Use Disorder?
This is particularly apparent when examining an individual’s risk of alcohol-related harm at a given level of alcohol consumption. Frequently, alcohol misuse does not occur in isolation but alongside other mental health disorders, a situation known as co-occurring disorders or dual diagnosis. Common co-occurring conditions include depression, anxiety, bipolar disorder, and PTSD. Treatment for alcohol dependence in such cases must address both the addiction and the mental health condition to ensure a holistic recovery. This dual approach helps prevent relapse and promotes a more stable, long-term recovery.

Or a doctor could prescribe drugs to assist with other emotions common in recovery. These complications are reasons why it’s important to treat alcohol addiction early. Nearly all risks involved with alcohol addiction may be avoidable or treatable, with successful long-term recovery. The severity of the disease, how often someone drinks, and the alcohol they consume varies from person to person.
Physical Dependence On Alcohol
Their craving for risk and novelty takes the fear out of drug use and the huge dopamine boost powerfully reinforces the motivation to seek the reward over and over again. Neuroscience research supports the idea that addiction is a habit that becomes deeply entrenched and self-perpetuating, rewiring the circuitry of physiological dependence on alcohol the brain as it is repeated. The repetition of a highly pleasurable experience—drugs, gambling—alters neurons; they adjust their wiring to become increasingly efficient at the experience. As drug use stops, engaging in other rewarding activities rewires the brain to find interest and pleasure in non-drug pursuits.
- Some current models of addiction emphasize the causative role of individual variations in biology or genes that make a substance or experience feel more or less pleasurable.
- Identifying problems with alcohol early can help prevent dependence and addiction.
- And the vast majority of people exposed to most substances (or activities) considered addictive do not in fact develop addiction to them.
Managing alcohol withdrawal
Social learning theory also provides some explanations of increased risk of excessive drinking and the development of alcohol dependence. People can learn from families and peer groups through a process of modelling patterns of drinking and expectancies (beliefs) about the effects of alcohol. Teenagers with https://ecosoberhouse.com/ higher positive expectancies (for example, that drinking is pleasurable and desirable) are more likely to start drinking at an earlier age and to drink more heavily (Christiansen et al., 1989; Dunn & Goldman, 1998). Stress is a risk factor for many kinds of nonadaptive behavior, and addiction is one.
Short-Term & Long-Term Effects of Alcohol on the Brain
Sometimes people drink alcohol to help with the symptoms of stress, anxiety, and depression. Alcohol changes the way your brain cells signal to each other, which can make you feel relaxed. If you think you may be dependent on alcohol, you should consult your doctor or another medical professional before stopping drinking. You could speak to a health professional at your GP surgery, or there are also a number of national alcohol support services that you can confidentially self-refer to for advice and support. Along with the weight disparities that allow higher alcohol use for men, the differences in the makeup of women’s bodies work against them when consuming alcohol.
The damage may be physical (e.g. hepatitis) or mental (e.g. depressive episodes secondary to heavy alcohol intake). Harmful use commonly, but not invariably, has adverse social consequences; social consequences in themselves, however, are not sufficient to justify a diagnosis of harmful use. Many different theories of addiction exist because they weight the role of contributing factors differently. Some current models of addiction emphasize the causative role of individual variations in biology or genes that make a substance or experience feel more or less pleasurable.
