Alcoholic Dementia | Can Alcoholic Dementia Be Caused By Alcoholism?

Published on

Chronic, long-term excessive alcohol consumption can result in alcoholic dementia, known by a number of different names. Most common after alcoholic dementia, is Korsakoff Syndrome.

Alcoholic Dementia

Alcohol affects the brain in a number of ways. Alcohol can directly affect neurons, leading to a negative impact on higher functions like insight, judgment, and decision making.

Alcohol tends to cause malnutrition and vitamin deficiencies when it is abused in excess over the course of several years. This can cause brain damage since the brain requires specific vitamins and nutrients to function properly.

The disease commonly referred to as alcoholic dementia is similar to Alzheimer’s Disease because it causes impairments to cognitive function and memory.

Other names that have been used to refer to alcoholic dementia include its official name; alcohol-induced neurocognitive disorder, Korsakoff Syndrome, Wernicke-Korsakoff Syndrome, and alcohol-related brain damage.

While all of these terms are used interchangeably in general conversation, they are not all the same disease, syndrome, or disorder.

Symptoms Of Alcoholic Dementia

The symptoms of alcoholic dementia vary more than Wernicke – Korsakoff syndrome, but the symptoms of alcoholic dementia are largely dependent on where the brain damage is located.

A person struggling with alcoholic dementia may display the following symptoms:

  • issues with impulsivity and emotion regulation
  • socially inappropriate behavior
  • poor decision-making, planning, judgment, and organizational skills
  • insensitivity
  • inattention

People with alcoholic dementia do not always lose day-to-day memory, which is a symptom-specific to Wernicke – Korsakoff syndrome.

Alcoholic dementia can be caused by a number of factors, not just malnutrition.

A person who drinks excessively for long periods of time end up with brain damage due to:

  • cerebrovascular disease due to alcohol consumption
  • repeated head trauma while intoxicated
  • toxic effects that alcohol has on brain cells
  • stress to the body from withdrawal and intoxication cycles over time

What Is Wernicke – Korsakoff Syndrome?

Wernicke-Korsakoff syndrome is actually two different issues that can happen together or separately, known as Wernicke’s encephalopathy and Korsakoff psychosis (or syndrome).

Wernicke’s encephalopathy is typically identified by confusion, muscle coordination issues – like leg tremors and unsteady gait, nystagmus (eye movement back and forth), double vision, drooping eyelids, progressive loss of mental activity that can lead to coma or death.

Wernicke’s encephalopathy causes damage to the thalamus and hypothalamus in the brain.

Korsakoff syndrome symptoms tend to emerge as Wernicke’s encephalopathy symptoms fade. These symptoms include severe loss of memory, fabricating stories, hallucinations, and being unable to form new memories.

Korsakoff psychosis is a result of permanent brain damage to areas that are responsible for memory formation and recall.

Causes And Symptoms Of Wernicke – Korsakoff Syndrome

A deficiency of thiamine, or vitamin B1, tends to be common among people with severe alcoholism. This particular deficiency is an issue because nerve cells have to have thiamine in order to work properly.

Thiamine’s purpose in the brain is to assist in energy production using sugar. Without thiamine, brain cells can not create the energy necessary to function correctly.

Failure to treat Wernicke’s encephalopathy will almost always lead to the development of Korsakoff syndrome.

Diagnosing Alcoholic Dementia

Diagnosing alcoholic dementia or any other form of alcohol-related brain damage is difficult to do if the person is still drinking. Medical professions recommend that a person has abstained from alcohol for at least a couple weeks to properly diagnose.

A person can expect to receive a complete physical examination and will be asked for a complete history as well. It is advised that the person brings a loved one who is very close to them to fill in any gaps due to impairment.

It will be important to disclose when symptoms started to emerge and an accurate recollection of current and past alcohol use and abuse. Tests evaluating mental abilities and potential mental illness are likely to be administered as well.

In some cases, a doctor may request a brain scan to rule out other potential causes for symptoms. Additionally, if the scan reveals that the cerebellum has shrunk, alcoholic dementia is more likely than another form of dementia.

If the following symptoms are present, a diagnosis of alcoholic dementia is probable:

  • impaired memory
  • defect reasoning
  • recent and persistent alcoholism history

In most cases, if a person can be diagnosed with an alcohol-induced neurocognitive disorder, they will likely be diagnosed with one of the following, depending on symptoms:

  • alcoholic dementia
  • Wernicke’s encephalopathy
  • Wernicke-Korsakoff syndrome
  • Korsakoff’s psychosis
  • alcohol amnestic syndrome

Treatment For Alcoholic Dementia

While some of the brain damage caused by alcoholism is irreversible, there is a significant chance of improvement if a person stops drinking, starts eating a well-balanced diet, and receives high doses of thiamine.

During the first phase of treatment for alcoholic dementia, most people require hospitalization. These first several weeks of treatment are for stabilization and may require an alcohol detoxification program that is medically supervised.

Often this will result in intense alcohol withdrawal symptoms, such as agitation, sweating, delirium tremens, hallucinations along with other withdrawal symptoms. Treatment includes benzodiazepines, rehydration, thiamine injections, and proper supplements and vitamins.

After a person is stabilized, they should have ongoing support from an alcohol treatment program and a physical rehabilitation facility.

Treatment For Alcoholism

Because some symptoms and effects of alcoholic dementia will diminish over time, as long as the person stops drinking, it is important to treat the underlying causes of alcoholism. This is achievable with an alcohol abuse treatment program.
