Cirrhosis, pancreatitis, and cardiovascular disease are some of the more common damaging effects of chronic alcohol abuse, but wet brain is also one of the lesser-known effects of alcohol addiction. Wet brain in aslcoholics is less common than some of the other side effects of alcohol abuse, but it can still occur. Here are the facts about wet brain causes, symptoms, and treatment.

What is Wet Brain?

“Wet brain” is a term used to describe the chronic brain disorder, Wernicke-Korsakoff syndrome or Korsakoff’s psychosis. Wet brain is caused by Thiamine (Vitamin B1) deficiency and typically occurs among people suffering from alcohol addiction.1 Wet brain from alcohol damages the lower parts of the brain known as the thalamus and hypothalamus and may also result in permanent brain damage and memory problems.

Who Gets Wet Brain?

People who regularly abuse alcohol for long periods of time are more likely than others to get wet brain, although it can also be caused by intense periods of vomiting or poor nutrition. Alcohol interferes with the body’s ability to absorb Vitamin B1, so people who binge drink on a regular basis or who consume large amounts of alcohol frequently may develop wet brain.

Signs and Symptoms of Wet Brain

Wet brain behavior may not always be immediately recognizable as the symptoms of wet brain may be misinterpreted as other health problems. However, unlike many of the other harmful effects of alcohol abuse that develop over time, wet brain occurs very suddenly and presents itself in two distinct stages.2

  • Wet Brain Symptoms, Stage 1: The first stage of wet brain is called Wernicke’s encephalopathy. Symptoms of Wernicke’s encephalopathy include:
    • A sudden decrease in mental ability
    • Confusion
    • Loss of muscle coordination
    • Leg tremors
    • Abnormal eye movements
    • Double vision
    • Eyelid drooping
    • Alcohol withdrawal
    • Coma
    • Death3
  • Wet Brain Symptoms, Stage 2: The second stage of wet brain is called Korsakoff’s psychosis or Korsakoff’s syndrome. Symptoms of Korsakoff’s psychosis:
    • Memory loss
    • Inability to form new memories
    • Making up stories
    • Auditory and visual hallucinations
Symptoms of Wet Brain
  • Staggering
  • Confusion
  • Loss of muscle coordination
  • Leg tremors
  • Making up stories (”remembering” events that didn’t happen)
  • Minor or severe memory loss
  • Inability to form new memories
  • Hallucinations (auditory and visual)
  • Double vision
  • Drooping eyelids
  • Abnormal eye movements

According to the National Institute on Alcohol Abuse and Alcoholism, approximately 80 to 90 percent of alcoholics with Wernicke’s encephalopathy develop Korsakoff’s psychosis.4

Can You Reverse Wet Brain?

Stage one of wet brain is completely reversible, but only if it is treated immediately with Vitamin B1 injections. However, if it is left untreated, it will progress to stage two of wet brain, which is only partially reversible. Stage two (Korsakoff’s psychosis) can improve over time with Vitamin B1 and abstinence from alcohol, but it can never fully be reversed.2

Wet Brain in Alcoholics

According to the National Organization for Rare Disorders, wet brain occurs in one to two percent of the U.S. population.5 Wet brain in alcoholics may occur for a few different reasons:

  • Poor nutrition: People who suffer from alcohol addiction or who abuse alcohol regularly are more likely to have poor diets and nutrition deficiencies, such as a B1 deficiency. Vitamin B1 doesn’t occur naturally in the body. Instead, it must be ingested by eating nutritious foods like poultry, whole grain cereals, nuts, and dried beans, among others. Alcohol also irritates and damages the tissues of the digestive tract, making it difficult for the body to absorb and digest nutrients from food.
  • Additional health problems: Alcoholics are also more likely to suffer from other health problems such as cancer, HIV/AIDS, heart failure, or long-term dialysis. These conditions may increase their risk of developing wet brain, as they also can cause Vitamin B1 deficiency.1
  • Increased vomiting: Episodes of vomiting can also severely deplete the body of essential nutrients and vitamins, like Vitamin B1. People with alcohol use disorder may vomit more than someone without the disorder because hangovers and alcohol overdose and poisoning are much more likely to occur on a regular basis.

Do I Have Wet Brain?

You may have wet brain if you have experienced some of these early symptoms:

  • Consistent vomiting
  • Anemia and/or nutritional deficiencies
  • Poor diet high in carbohydrates that are not whole grains
  • Rapid weight loss/reduced BMI

You may have Wernicke-Korsakoff syndrome if you have experienced some of these early symptoms:

  • Insomnia
  • Memory loss
  • Frequent nausea and vomiting
  • Loss of appetite
  • Fatigue
  • Giddiness (for no apparent reason)
  • Difficulty concentrating

The best way to find out if you have wet brain or Wernicke-Korsakoff syndrome is to see a doctor. Your doctor can provide an accurate diagnosis and help you find treatment for alcohol addiction once your physical health has recovered.

Treating Wet Brain

It’s ideal to start treating wet brain right away, because waiting until it progresses to stage two could be more harmful and potentially fatal.6 According to MedlinePlus, the primary goals of wet brain treatment are to control the symptoms of wet brain and prevent the disorder from worsening. There are several different methods for achieving these goals, including:

  • Vitamin B1 injection
  • Complete abstinence from alcohol
  • Implementation of a well-balanced and nutritious diet

If a person with wet brain is unconscious or in a coma, they will need special care in a medical environment, and potentially, for a longer period, depending on the severity of their symptoms.

Alcohol Detox and Rehab Treatment

Even if a person is diagnosed with wet brain, it may still be very difficult for them to abstain from consuming alcohol. This is especially true if the person is addicted to alcohol or physically dependent on it, which can be difficult for friends and family members to accept. It’s important to remember, however, that alcohol addiction is a chronic and powerful disease and the way an alcoholic behaves won’t always make sense to loved ones.

Once the immediate or life-threatening symptoms of wet brain have been treated, the affected person can begin to focus on preventing further memory loss and brain damage by completely eliminating alcohol from their lifestyle. Getting sober and quitting alcohol for good will prevent the loss of additional brain functions and eliminate further nerve damage.1

If you or a loved one is an alcoholic or has been diagnosed with alcohol use disorder, a medically-assisted inpatient alcohol detox program can help you safely detox from alcohol without complications.

Alcohol withdrawal symptoms can be severe and even deadly, in some cases, so detoxing under medical supervision is always the safest and most effective way to quit alcohol and begin a new, sober lifestyle.

Despite its efficacy, an alcohol detox program on its own is not a solution for long-term sobriety. Continuing your addiction treatment with a drug and alcohol rehab program can help you develop the necessary life skills and coping strategies to maintain your sobriety.
