Our Brains, Addiction & Alcohol

Addiction is a chronic and progressive biological disease that involves the reward system of the brain and manifests in many ways. Addiction can involve alcohol, prescription drugs, illicit drugs, food, and behaviors such as sex and gambling. It’s estimated that 20 million people suffer from addiction (Townsend Treatment Centers, 2016), and addiction involving alcohol is an increasingly common diagnosis.

Hard to Escape
Alcohol is everywhere in today’s society – pubs serving craft ales, beer at baseball games, cocktails after work, wine with dinner, and lots of other celebrations where margaritas and other festive cocktails are served. Why do we drink? As a central nervous system depressant, alcohol brings about relaxation and helps millions of people wind down with a drink each night.

Physical Effects of Alcohol Use

Besides the interplay of alcohol use, the brain, and addiction, excessive use of alcohol can bring about harmful physical consequences to a number of systems throughout the body. While moderate drinking may come with limited risks, heavy drinking and binge drinking can take a serious physical toll on the body. Alcohol enters the bloodstream through the intestinal tract and is then carried to all parts of the body. When alcohol is consumed excessively over a person’s lifetime, major organs can suffer significant damage.

Harm to Organ Systems
Liver disease, including increased fat, inflammation, and scarring of the liver can all occur as a result of chronic alcohol abuse. Damage to other major organs is also common, including inflammation of the stomach lining, damage to the pancreas, heart, eyes, bones, and nervous system. Excessive alcohol consumption also can result in birth defects, a weakened immune system, sexual dysfunction, and increased risk of cancer.

Consequences of Alcohol Overuse
People with addiction involving alcohol are unable to control their drinking despite its negative effects on their lives. Despite the damage they incur when continuing to drink, they’re unable to stop on their own while interpersonal relationships, family, career, health, and finances suffer.

Medical Treatment for Safe Detox
As a disease, alcoholism requires medical treatment. It is not a matter of willpower or determination; people suffering from alcohol addiction need professional help, just as those dealing with other medical diseases, like diabetes or heart disease. Since the physical alcohol detox process may result in a multitude of serious risks, including life-threatening withdrawal symptoms, individuals dealing with addiction involving alcohol should never attempt to detox on their own; medical detox is necessary to ensure safety throughout the process.

Who Is at Risk for Alcoholism?

Over half of adults in U.S. report drinking alcohol, according to the Substance Abuse and Mental Health Services Administration (SAMHSA).

Most people can drink moderate amounts of alcohol with no problem but for others, alcohol use can becomes problematic. About 6 percent of regular drinkers have an alcohol use disorder, the formal name for alcoholism. This disorder is characterized by lack of control, preoccupation with alcohol, a level of drinking that causes problems in daily life, and a physical dependence on alcohol. When a person begins drinking at a young age, or regularly has more than 4-5 drinks at a time, chances of developing an alcohol use disorder increase.

Who Is at Risk for Alcoholism?

Risk Factors
Various factors can contribute to the risk of developing an alcohol use disorder. Mayo Clinic lists the following risk factors for development of an alcohol use disorder:

  • Regularly drinking large amounts of alcohol
  • Beginning drinking at a young age
  • Having friends or partner who regularly drink large amounts of alcohol
  • Suffering from depression or other mental health problems
  • Having family history of alcohol abuse

The presence of risk factors doesn’t mean that a person will become an alcoholic. Instead, it increases the likelihood of developing problems with alcohol consumption. Those with awareness of their risk factors for alcohol abuse can take extra precaution by managing their drinking or avoiding alcohol consumption altogether.

Alcohol Dependence & Disorders

characteristics of alcohol dependence

Dependence or Behavior?
It is possible to have an alcohol use disorder without alcohol dependence, which means the person is not physically dependent on alcohol, but engages in a level of drinking that is problematic. A person who consumes a large amount of alcohol in a short period of time (“binge drinking”) a few times per month may not be physically dependent on alcohol but this pattern of drinking is problematic and may indicate alcohol use issues.

Alcoholism: Chronic & Progressive
Physical dependence on alcohol happens when a person’s body becomes accustomed to having a certain level of alcohol in the system at all times. As the alcohol use progresses, a tolerance occurs and increasing amounts of alcohol are necessary to feel the same effect. When physical dependence and tolerance are present, as alcohol levels decrease and as alcohol leaves the body, the person may experience physically unpleasant and often dangerous withdrawal symptom

The National Library of Medicine lists the following characteristics of alcohol dependence:

  • Cravings
  • Withdrawal symptoms when you stop drinking
  • Feeling like you’ve lost control over drinking
  • Physical dependence
  • Increased tolerance to alcohol
  • You spend a lot of time drinking or recovering from drinking
  • Anxiety
  • Depression
  • Fatigue
  • Irritability
  • Shakiness and tremors
  • Mood swings
  • Nightmares
  • Difficulty thinking clearly
  • Sweating
  • Dilated pupils
  • Headache
  • Difficulty sleeping
  • Loss of appetite
  • Nausea and vomiting
  • Increased heart rate
  • Agitation
  • Fever
  • Hallucinations
  • Depression, anxiety
  • Seizures
  • Severe confusion
  • Drinking more than intended
  • Wanting to stop drinking but unable to do so
  • Spending a lot of time drinking
  • Being in dangerous situations, such as driving under influence or engaging in unsafe sex, as a result of drinking
  • Drinking interferes with daily life
  • Continuing to drink despite the problems it causes
  • Stopping past enjoyable activities for more time to drink
  • Continuing to drink despite depression or anxiety
  • Drinking increasing amounts of alcohol to achieve same effects
  • Experiencing withdrawal symptoms when not drinking
  • Craving alcohol when not drinking

Alcohol Poisoning

Who Gets Alcohol Poisoning?
People with alcohol use disorders as well as binge drinkers are at increased risk of alcohol poisoning. A binge is defined as consuming more than 4-5 alcoholic beverages in one sitting. Binge drinkers tend to drink alcohol quickly, and drink with the intention of getting drunk.According to the Centers for Disease Control and Prevention, binge drinking is a major problem in the U.S., and one in six adults binge drink an average of once per week.

How Does Alcohol Poisoning Happen?
Alcohol poisoning occurs when an individual consumes more alcohol than the body can process at one time. Per Mayo Clinic, alcohol poisoning is a medical emergency that can lead to death. Without emergency medical assistance, a person experiencing alcohol poisoning can slip into a coma or even die. Symptoms of alcohol poisoning include:

Alcohol Poisoning
  • Abdominal pain
  • Stupor or loss of consciousness
  • Confusion
  • Stomach and intestinal bleeding
  • Shallow breathing
  • Slurred speech
  • Unsteady walking
  • Vomiting
  • Coma

Emergency Treatment
There are no home remedies to treat alcohol poisoning. Attempts to put the person in a cold shower or drink coffee will not be successful, and could lead to accidents and further injuries. In cases of alcohol poisoning, call 911 immediately.

Effects of Alcohol Poisoning
People who survive alcohol poisoning are lucky. The worst thing they can do is to have repeated cases of alcohol poisoning. With repeated cases, permanent and sometimes fatal organ damage or organ failure may result. Liver disease and heart disease are common among individuals who have abused alcohol for many years.

Treating Alcohol Use Disorders

Treating Alcohol Use Disorders

Medical Detox
For some individuals, treatment for their alcohol dependence begins with detox and withdrawal. Because withdrawal from alcohol can involve dangerous complications, detox must be completed under medical supervision. Any at-home “cold turkey” detox attempts could result in life-threatening health complications.

Safe Detox Environment
In a professional detox program, medical professionals monitor clients around the clock, providing supervision and support throughout the entire detox process. In some instances, medications may be used during the detox process to manage withdrawal symptoms and promote abstinence. Medications may also be prescribed to treat specific detox symptoms, such as antidepressants to deal with sadness common during detox or anti-nausea medications to manage intestinal issues.

  • Naltrexone: This medication blocks the effects of alcohol on the brain and body. This helps to discourage relapse, because drinking will not have the intended effects. Compliance with this medication can be low, so it is not always effective. A new form of the drug is available as a monthly injection, which may improve rates of compliance.
  • Acamprosate: This medication is used to ease symptoms of withdrawal. It addresses symptoms like insomnia, anxiety, restlessness, and dysphoria. Taking acamprosate may help individuals stay sober for longer lengths of time, particularly if they suffer from severe alcohol dependence.
  • Disulfiram: This medication discourages relapse by causing individuals to feel sick if they drink alcohol. Drinking alcohol while taking disulfiram causes flushing, nausea, and heart palpitations. People who are highly motivated to stop drinking generally do well with disulfiram.

Multidisciplinary Treatment
While medications can be important in alcohol addiction treatment, they should only be used as part of a comprehensive treatment program. Therapy that addresses the root causes that led to alcohol abuse is needed. Various methods of therapy are used to treat alcohol use disorders, including Cognitive Behavioral Therapy, family therapy, Motivational Enhancement Therapy, and alternative therapies, such as adventure therapy, art therapy, music therapy, and animal-assisted therapy.

Individual Treatment Needs
An addiction treatment program, for alcohol addiction or for any other substance addiction, should be tailored to meet the needs of the individual client. There is no one-size-fits-all method of care that will work for everyone. Instead, the needs of the individual need to be assessed, and reassessed, throughout treatment to ensure the best care plan possible for the individual.
