This is one of the reasons that addiction is classified as a chronic disease. Although it can be managed and treated, like other chronic health conditions, at this time there is no “cure” for addiction. The hormonal stress response is mediated by a system known as the hypothalamic–pituitary–adrenocortical axis. Within this system, stress induces the release of the hormone corticotrophin-releasing factor from a brain area called the hypothalamus. CRF acts on the pituitary gland located directly below the hypothalamus, where it initiates the production of a molecule called proopiomelanocortin . This compound is processed further into smaller molecules, such as β-endorphin and adrenocorticotropic hormone . ACTH is carried via the blood stream to the adrenal glands , where it induces the release of stress hormones (i.e., glucocorticoids) that then act on target cells and tissues throughout the body .

Alcohol withdrawal syndrome can be very tricky to diagnose, due to other preliminary conditions that may exist from individual to individual. We strive to make every patient that walks into our office feel comfortable and genuinely welcome. We listen instead of label; if you’re physiologically dependent or have a substance use disorder, physiological dependence on alcohol we’ll work with you. Every single patient we approve gets a customized treatment plan that matches their lifestyle and their needs — we even offer telemedicine options. Because physiological dependence is a warning sign, you’ll need to know how to spot it. For many, the withdrawal symptoms are the wakeup call they need to make changes.

Psychological Dependence

Physical addiction appears to occur when repeated use of a drug changes the way your brain feels pleasure. The addicting drug causes physical changes to some nerve cells in your brain. Examples include methylenedioxymethamphetamine, also called MDMA, ecstasy or molly, and gamma-hydroxybutyric acid, known as GHB. Other examples include ketamine and flunitrazepam or Rohypnol ― a brand used outside the U.S. ― also called roofie. These drugs are not all in the same category, but they share some similar effects and dangers, including long-term harmful effects. Diagnosis is based on a conversation with your healthcare provider. The diagnosis is made when drinking interferes with your life or affects your health.

What is considered heavy drinker?

For men, heavy drinking is typically defined as consuming 15 drinks or more per week. For women, heavy drinking is typically defined as consuming 8 drinks or more per week.

Enhanced negative emotion and alcohol craving, and altered physiological responses following stress and cue exposure in alcohol dependent individuals. The role of corticotrophin-releasing factor in stress-induced relapse to alcohol-seeking behavior in rats. Zhang Z, Morse AC, Koob GF, Schulteis G. Dose- and time-dependent expression of anxiety-like behavior in the elevated plus-maze during withdrawal from acute and repeated intermittent ethanol intoxication in rats.


Once you’ve realized that you need tools and guidance, choosing a treatment program that provides what you need will get the recovery process underway. Like other chronic, relapsing diseases, including high blood pressure and diabetes, treating drug addiction is an ongoing process. If a relapse occurs, this is not a failure of treatment; it is a sign that ongoing, different, or more intensive treatment is needed to control the disease. DrugAbuse.govoffers an insightful explanation based on brain image studies from people addicted to drugs. The study found, physical changes in areas of the brain that are critical for judgment, decision making, learning, memory, and behavior control in addicted people. Scientists believe that these changes alter the way the brain works and may help explain the compulsive and destructive behaviors of an addicted person. When most people think of physical addiction, they are usually attributing it to the thought of the physical withdrawal symptoms that occur when someone stops giving their body the substance they have been using regularly.

Viral vector-induced amygdala NPY overexpression reverses increased alcohol intake caused by repeated deprivations in Wistar rats. Schulteis G, Markou A, Cole M, Koob GF. Decreased brain reward produced by ethanol withdrawal. Rassnick S, Stinus L, Koob GF. The effects of 6-hydroxydopamine lesions of the nucleus accumbens and the mesolimbic dopamine system on oral self-administration of ethanol in the rat.

Understanding Why Alcohol Is Physically Addictive

There is no such thing as not being “alcoholic enough.” There is no reason to wait until you feel like your drinking is bad enough to warrant treatment. You can ask for help at any point, whenever you realize your drinking has gone too far. These drinkers have a drink in their hand at most or all social gatherings. You might notice it if they use it as their go-to way to unwind after a challenging day or long week.

The differences between the two can be hard to distinguish, but one does not mean the other. Roy A, Pandey SC. The decreased cellular expression of neuropeptide Y protein in rat brain structures during ethanol withdrawal after chronic ethanol exposure. Rassnick S, Pulvirenti L, Koob GF. Oral ethanol self-administration in rats is reduced by the administration of dopamine and glutamate receptor antagonists into the nucleus accumbens. Effects of naltrexone, duloxetine, and a corticotropin-releasing factor type 1 receptor antagonist on binge-like alcohol drinking in rats. The GABAA receptor α1 subtype in the ventral pallidum regulates alcohol-seeking behaviors. Gilpin NW, Richardson HN, Lumeng L, Koob GF. Dependence-induced alcohol drinking by alcohol-preferring rats and outbred Wistar rats.

Psychological dependence only

The change is due to neurotransmitters sending higher levels of certain chemicals. When the drug is stopped, the dopamine levels in the brain decrease. Lower dopamine levels result in irritability, sadness, and other depressing thoughts.

Becker HC, Veatch LM. Effects of lorazepam treatment for multiple ethanol withdrawals in mice. When consumed, alcohol is metabolized by a liver enzyme and eliminated through the urine.

Alcohol increases the brain levels of many neuroactive steroids (Van Doren et al. 2000). This increased activity of neuroactive steroids in the brain following alcohol exposure is not dependent on their production by peripheral organs (Sanna et al. 2004).

Can the brain heal itself after alcohol?

Alcohol related brain damage and recovery. Studies into the effects of alcohol on the brain have shown that the brain is able to repair itself remarkably quickly after stopping drinking.
