Can Severe Alcoholism Cause Dementia? Alcohol-Related Brain Damage

From 2009 to 2011, 24.2% of mild drinkers, 8.4% of moderate drinkers, and 7.6% of heavy drinkers became quitters. In the same period, 13.9% of nondrinkers, 16.1% of mild drinkers, and 17.4% of moderate drinkers increased their drinking level. Study participants completed questionnaires on their drinking habits and were assigned to one of five groups according to change in alcohol consumption during the study period. These groups consisted of sustained nondrinkers; those who stopped drinking ; those who reduced their consumption of alcohol but did not stop drinking ; those who maintained the same level of consumption ; and those who increased their level of consumption .

  • Alzheimer’s disease is a degenerative brain disorder characterized by a progressive loss of memory and other detrimental cognitive changes as well as lowered life expectancy .
  • Thiamine deficiency or Vitamin B1 deficiency is common with dementia and alcoholism due to a poor diet.
  • Research in mice suggests that an mRNA modification therapeutic approach may help reduce the symptoms of Alzheimer’s disease.
  • Buddy T is an anonymous writer and founding member of the Online Al-Anon Outreach Committee with decades of experience writing about alcoholism.

Also, Reid et al. explicitly included only studies which separated lifetime abstainers and former drinkers . Surprisingly, they found that having an alcohol use disorder was the strongest predictor of a dementia diagnosis, for both men and women, out of all the potential risk factors included in the analysis. The association between alcohol use and dementia remained significant across all age groups in the study, and across all different types of dementia, including Alzheimer’s disease. Cognitive and behavioral changes specific to ARD have received limited investigation.

About the study

Alcohol addiction treatmentoptions include outpatient and inpatient treatment. Outpatient treatment involves going to regular physical and mental health appointments to get treatment and learn how to overcome alcohol addiction while otherwise keeping any work and social obligations. Inpatient treatment requires more dedication and involves living in a rehab center to get intensive treatment that is more likely to have a lasting effect. There is some debateabout whether alcohol use increases the risk of developing Alzheimer’s disease at all, or whether it increases the chance that it will occur at an earlier age than it usually would.

  • Cholinergic neurotransmission in the basal forebrain, which plays a key role in attention, learning, and memory, also appears to be impacted by prolonged intake of alcohol.
  • Signs and symptoms of alcoholic dementia and the conditions it may cause often come on gradually.
  • There are no specific laboratory tests or neuroimaging procedures to confirm that a person has this disorder.
  • A standard drink is equal to 14 grams or 0.6 ounces of pure alcohol.
  • Heavy alcohol consumption has both immediate and long-term detrimental effects on the brain and neuropsychological functioning (Delin and Lee 1992; Evert and Oscar-Berman 1995).

For instance, 5 percent of alcoholics in withdrawal experience delirium tremens . Any person who drinks alcohol heavily over many years can develop alcohol-related dementia. It is unknown can alcoholism cause dementia why some heavy drinkers develop dementia, and others don’t. Alcoholism or alcohol use disorder damages brain cells and interferes with using good judgment and decision making.

Late-Onset Alcohol Abuse Can Be a Presenting Symptom of Dementia, Researchers Find

Some studies highlighted that the selection processes used in cohort studies may lead to underestimation of the associations between alcohol use and cognitive impairment or dementia . Second, most of the studies on alcohol use and cognitive decline/dementia concerned older subjects (; Table 1). In particular, there was an observed increase in the risk of an alcohol-attributable death at lower levels of use, such as 30 g of pure alcohol per day, and risk accelerated exponentially as average use increased . Former drinkers were usually grouped with lifetime abstainers to create a control group , leading to a lack of control for “sick quitters” (that is, people who quit drinking because of health problems ).

Even if you exercise daily, you should still eat healthy foods such as fruits, vegetables, and whole grains. A holistic approach to treatment addresses all these areas by providing support for mind-body wellness, nutrition, exercise, and traditional psychotherapy. Our holistic program offers a variety of therapeutic approaches that allow you to increase your self-awareness, gain new skills, and learn how to make healthy choices. Ethanol is the main ingredient in alcoholic beverages that makes you feel tipsy or drunk. It interferes with your brain chemistry by lowering its inhibitory processes.

Contribution of alcohol use disorders to the burden of dementia in France 2008–13: a nationwide retrospective cohort study

One methodological challenge of both case-control and cohort studies is the separation of AD from alcoholic dementia. AD cannot be definitively diagnosed clinically but instead requires confirmation based on examination of the brain after death. Even when AD is accurately diagnosed before death, study participants still represent a heterogeneous group, differing in age at onset, duration, and genetic basis of AD. Case-control studies may introduce bias by using heavy alcohol consumption as an exclusionary criterion for AD cases but not for controls (e.g., Graves et al. 1991). As alcoholic dementia has not been uniformly diagnosed across epidemiologic studies, the discrimination of alcoholic dementia from AD also is problematic. Alcohol dementia refers to an alcohol-induced major neurocognitive disorder.

can alcoholism cause dementia

Research has shown that severe thiamine deficiency disrupts several biochemicals that play key roles in carrying signals among brain cells and in storing and retrieving memories. These disruptions destroy brain cells and cause widespread microscopic bleeding and scar tissue. Researchers have identified several genetic variations that may increase susceptibility to Korsakoff syndrome. Alcohol misuse may reduce your brain’s ability to form new memories.
