Key Points
- Wet brain syndrome is a neurological disorder caused by chronic thiamine deficiency
- Also called Wernicke-Korsakoff Syndrome (WKS), wet brain is a form of dementia
- WKS has two phases: Wernicke's encephalopathy, marked by confusion and coordination issues, and Korsakoff's psychosis, which leads to severe, lasting memory problems.
- Diagnosing WKS involves reviewing the patient's medical history and a physical check-up. Brain scans and blood tests are also typically used to confirm low thiamine levels.
- Wet brain syndrome may be treated with thiamine supplementation
- High doses of thiamine early on can reverse some of the damage, but delaying treatment often results in permanent brain impairment.
- Recovering from wet brain syndrome requires abstinence from alcohol
- Treating wet brain syndrome often requires treating alcohol use disorder
Wet brain syndrome, or simply wet brain, is a form of serious dementia common in those with chronic alcohol abuse. Also known as Wernicke-Korsakoff Syndrome, wet brain arises from a prolonged lack of thiamine. Our brains require a constant and plentiful supply of thiamine (vitamin B1). Without it, potentially irreparable brain damage will result. WKS is not common. Although many alcoholics don’t get enough thiamine, only a minority go on to develop full-blown WKS, or Wet Brain Syndrome.[1]
Talking About Wet Brain Syndrome
“Wet brain syndrome” is a common but non-clinical term for Wernicke-Korsakoff Syndrome. WKS is a two-stage brain disorder that includes:
Wernicke’s Encephalopathy (WE). WE is the first stage in the progression of wet brain syndrome. Many people suffering from alcohol addiction get WE. Symptoms often include confusion, problems with eye movement, an unsteady gait, and poor coordination. If caught early and treated with high-dose thiamine, WE can often be reversed.
Korsakoff Syndrome: This is the more chronic and often longer-lasting phase of the condition. It can develop if Wernicke’s encephalopathy isn’t treated effectively. The hallmark of Korsakoff Syndrome is severe memory loss, particularly the inability to form new memories.[2] People might also confabulate, meaning they unintentionally make up stories to fill in memory gaps, and experience other changes in their thinking and behavior. The brain damage from Korsakoff Syndrome can be permanent.[3]
Thiamine Deficiency and Wet Brain: What are the Connections?
Understanding Wernicke-Korsakoff Syndrome begins with understanding the brain’s reliance on thiamine, also known as vitamin B1.[4] Our brains need thiamine to convert blood sugar into energy that brain cells require to function. The brain is an energy-hungry organ, and its thiamine supplies must be constantly replenished.
Without thiamine, brain tissue begins to die. The process takes a while, but an alcohol-related thiamine deficiency will produce life-threatening health issues.
Alcohol Impairs the Brain by Interfering with Thiamine
Alcohol-induced thiamine deficiency is slow, severe, and can be fatal.[5] Excessive alcohol consumption impairs the body’s ability to turn thiamine from food into its active form. The brain requires an active form of thiamine for its cells to function properly.
But the situation gets worse. People who chronically abuse alcohol typically live with moderate to severe malnutrition. Drinking alcohol becomes an alcoholic’s main source of calories, but it has no nutritional value. Without proper nutrition, a thiamine deficiency is likely to cause wet brain in those with alcohol addiction.
Alcohol also irritates the lining of the stomach and intestines. This severe inflammation slows down and often stops the body from absorbing any nutrients, including thiamine.
People with long-term alcohol abuse don’t take in enough thiamine, and what they do take in is poorly absorbed because of the irritation alcohol abuse causes in the digestive tract. Then, the small amount that reaches the bloodstream may not be efficiently converted into its active form, thiamine pyrophosphate (TPP), because chronic alcohol use interferes with liver enzymes and magnesium levels necessary for this conversion. [6]
How Thiamine Deficiency Leads to Wet Brain Syndrome
Nerve cells in the brain require a significant amount of energy. The brain requires thiamine within every nerve cell to change glucose into useful energy. Without it, these are a few of the consequences.
Energy Starvation. Without sufficient thiamine in its active form, nerve cells function incorrectly. Some cells begin to die.
Toxic Buildup. Toxic byproducts of chemical reactions build up when brain cells lack sufficient energy. This is oxidative stress, which exacerbates damage to brain cells.
Chemical Imbalance. A lack of thiamine leads to an excess of glutamate, a neurotransmitter that stimulates brain cells. Millions of brain cells start firing too rapidly and incorrectly. Too much stimulation when cells are already starving from a lack of thiamine kills many of them.
Brain Damage. Major sections of the brain, such as those responsible for memory, balance, and eye movement, suffer the most because they require the most energy. This can lead to serious problems like memory loss, trouble walking, and unusual eye movements, which are symptoms of wet brain syndrome.
Symptoms of Wet Brain Syndrome
Wet brain includes Wernicke’s Encephalopathy (WE) and, if untreated, Korsakoff’s Syndrome. Early signs of WE include abnormal eye movements, poor muscle coordination, and confusion at all times. Treating wet brain is most effective during this stage. Most of the damage done by thiamine deficiency can be repaired during WE.
Korsakoff’s Syndrome, or Korsakoff’s psychosis, follows if WE remains untreated. Korsakoff’s Syndrome includes severe memory loss, particularly the inability to form new memories. People might also confabulate, meaning they unintentionally make up stories to fill in memory gaps.
These are the typical symptoms of wet brain syndrome broken down by functional area:[7]
Memory & Cognitive Issues
- Severe memory impairment
- Gaps in memory
- Confabulation (fabrication of stories to fill memory gaps)
- Hallucinations
- Permanent cognitive deficits
- Reduced consciousness
- Mood disturbances like depression, apathy, or irritability
Motor & Coordination Issues
- Disorientation
- Difficulty walking or standing
- Impaired coordination and balance (ataxia)
- Impaired ability to perform the activities of daily living
- Diminished ability to live independently
Abnormal Eye Movements
- Paralysis or weakness of the eye muscles can lead to double vision, drooping eyelids, and difficulty tracking objects properly.
- Involuntary, rhythmic back-and-forth eye movements (nystagmus)
- Misalignment of the eyes, often causing crossed eyes (strabismus)
- Rapid, tremor-like eye movements
- Impaired ability to follow moving objects with the eyes
Diagnosing Wet Brain Syndrome
Diagnosing WKS first requires identifying a person’s symptoms. Doctors will also order a physical exam, blood tests, and a brain scan.[8] Usually, treatment professionals will gather information from people in the individual’s daily life, if possible.
Treating Wet Brain Syndrome
Treating wet brain involves healing the brain and digestive tract.[9] At the same time, people need to address their behaviors that contributed to their WKS. Because heavy alcohol consumption is usually the root of WKS, a person must remain abstinent from alcohol.
These are the most common approaches to treating WKS:
- Intravenous Thiamine. Treatment with high-dose IV thiamine injections is a cornerstone of healing WKS.
- Psychological Support. Addiction and mental health services are essential for people with wet brain. Support groups can also help a person work through their symptoms of wet brain.
- Ongoing Monitoring. Early diagnosis and treatment are crucial for maximizing the chance of recovery. Regular follow-ups with healthcare providers, including blood tests to monitor thiamine levels and cognitive assessments, are important.
Other beneficial therapies for wet brain syndrome include:
- Cognitive Behavioral Therapy (CBT)
- Somatic experiencing
- Experiential therapy
- Nutritional counseling
- Group therapy
- Eye movement desensitization and reprocessing therapy (EMDR)
- Brainspotting
- Outdoor recreation
Wet brain syndrome is preventable; early diagnosis makes a big difference in treatment success. Recovery takes addiction treatment and overall medical care. It also demands lifestyle change and ongoing support. With help, many people regain independence and enjoy better health.
