Part of the complete guide to understanding addiction
Alcohol addiction carries numerous risks, both physically and mentally. One of the most significant risks is Wet Brain Syndrome, also known as Wernicke-Korsakoff Syndrome (WKS). In some cases, Wet Brain can develop within weeks or months.
Join Avenues Recovery, experts in addiction treatment, to explore Wet Brain, its symptoms, risks, and treatment options.
What is Wet Brain Syndrome?
Wet Brain (Wernicke-Korsakoff syndrome) is a neurological disorder caused by a severe deficiency of thiamine. Thiamine, also known as Vitamin B1, is essential for proper heart, muscle, and brain function and is typically obtained through proper diet. Vitamin B1 is necessary for your brain to turn carbohydrates, like sugar and starches, into energy. When your brain and nervous system do not receive an adequate amount of energy, they cannot function at healthy levels.
Wernicke-Korsakoff syndrome involves two distinct brain disorders, each with its own set of symptoms: Wernicke’s disease and Korsakoff’s psychosis. They often occur together.
Wernicke's disease, also known as Wernicke’s encephalopathy, is the more severe phase of the disorder. It develops relatively quickly, and affected individuals require treatment. If people don’t receive timely treatment for Wernicke's disease, it can develop into Korsakoff's psychosis.
Korsakoff's psychosis is a long-term condition. Unfortunately, over 80% of people who suffer from Wernicke’s syndrome will develop Korsakoff syndrome. Below we will look at the various symptoms that characterize these two wet brain stages.
How is Alcohol Misuse Connected to Wet Brain Syndrome?
Although wet brain isn’t exclusively associated with chronic alcohol misuse and severe alcohol use disorder (AUD), they are the most common causes of this disease. Wernicke-Korsakoff syndrome occurs in only 1-2% of the general population, while an estimated 12-14% of alcoholics are likely to suffer from wet brain. Excessive alcohol consumption over a sustained period of time can lead to these two disorders for several reasons:
- Poor nutrition - The body does not produce thiamine on its own and typically obtains the vitamin through a proper diet. Many foods are naturally rich sources of B1, including fish, meat, legumes, fruits, vegetables, and fortified products like cereals, breads, and rice. Alcohol is high in calories but lacks vitamins and minerals, leading alcoholics to consume empty calories. This results in poor nutrition and vitamin deficiencies, causing inadequate thiamine absorption (1.1mg/day for women, 1.2mg/day for men). Additionally, alcohol suppresses appetite, causing poor dietary habits and increasing the risk of thiamine deficiency.
- Alcoholic gastroenteritis - Inflammation of the stomach lining can cause vomiting or diarrhea. This impairs the absorption of thiamine as it prevents nutrients from being absorbed into the gastrointestinal tract.
- Alcoholic liver disease – Alcoholic liver disease drastically reduces the thiamine storage capacity of the liver by as much as 73%.
Wet Brain Symptoms
This condition manifests in two stages: Wernicke’s encephalopathy and Korsakoff’s psychosis, each with their distinct symptoms.
Symptoms of Wernicke’s Disease
Neuropsychiatric symptoms of wet brain occur when thiamine levels go below 20% of normal. The NIAAA explains that damage occurs in multiple brain regions, most notably the thalamus, hippocampus, hypothalamus, and cerebellum. Each of these areas controls different parts of the overall functioning of the body. The fact that they are all impacted has an adverse effect on many different parts of the body. The three primary symptoms of Wernicke’s syndrome include:
- Confusion and disorientation: The affected person may have difficulty focusing, understanding their surroundings, and following conversations.
- Lack of muscle coordination: Also known as Ataxia, this affects coordination, posture, and balance, and can lead to tremors - involuntary movements in one or more parts of the body.
- Vision problems: Affected persons may experience vision problems, including abnormal eye movements (e.g., involuntary back-and-forth movements, called nystagmus), double vision, misaligned or crossed eyes, and eyelid drooping. Another condition is ophthalmoplegia, which is the weakness or paralysis of certain eye muscles. All of these can cause vision disturbances.
Symptoms of Wernicke's disease can develop relatively quickly, often within a matter of days to weeks.
Symptoms of Korsakoff’s Syndrome
Korsakoff's syndrome is the chronic phase that may follow Wernicke's disease when it is left untreated or is treated insufficiently. Symptoms of Korsakoff's syndrome are characterized by those listed above, as well as:
- Memory impairment: In the journal article Korsakoff’s Syndrome: A Critical Review, the authors state that KS affects both “episodic memory, related to explicitly remembered personally experienced events specific to time and place, and semantic memory, related to facts.” Commonly referred to as alcoholic dementia, individuals may struggle to remember recent events and form new memories. Typically, the ability to learn new information (anterograde memory) is more severely impacted than the ability to recall memories from before the condition began (retrograde memory).
In severe cases, this memory impairment can be irreversible. - Problems with decision-making: Problems with decision-making are a direct offshoot of memory impairment, with individuals also experiencing difficulty planning, organizing, and completing tasks.
- Confabulation: Affected individuals may remember events incorrectly, and then to compensate for memory gaps, they will inadvertently invent inaccurate stories about events or "fill in" information with false details.
- Apathy and lack of insight: People with Korsakoff's syndrome may seem indifferent or uninterested and may not fully understand the extent of their memory deficits.
- Hallucinations: Individuals may see or hear things that are not really there.
- Repetitive speech and actions: Individuals may frequently repeat the same words or actions.
Is Wet Brain Preventable?
While abstaining from alcohol use is critical to prevent and reduce additional brain damage at all stages of wet brain syndrome, the NIAAA explains that “when someone who has been drinking heavily for a prolonged period suddenly stops drinking, the body can go into a painful or even potentially life-threatening process of withdrawal.” Thus, individuals suffering from addiction to alcohol and wet brain should seek medical help where they can be guided on how to withdraw from it safely.
Is Wet Brain Reversible?
Wernicke Korsakoff syndrome is a serious medical condition that requires proper diagnosis and treatment. Some Wernicke Korsakoff syndrome symptoms may be reversible if detected early and treated with thiamine supplementation, whereby thiamine is administered intravenously. If the intervention is successful, individuals can regain some of their lost functionality.
Without prompt treatment, Wernicke’s disease can progress to Korsakoff’s psychosis, which is irreversible. Left untreated, Wernicke Korsakoff syndrome will prove fatal in an estimated 20% of cases, while approximately 75% of wet brain patients will suffer permanent brain damage.
Wet Brain Treatment
It's crucial to seek medical attention if you suspect someone may be experiencing Wernicke-Korsakoff syndrome or see signs of wet brain syndrome. Early diagnosis and intervention can make a significant difference in the outcome and quality of life for the affected individual.
