Does Alcohol Abuse Lead To Dementia?

However, there are doubts regarding the etiopathogenesis, nosological status, prevalence and diagnostic criteria for ARD, due to difficulty in assessment and various confounding factors. Finally, alcohol-related brain damage may be present in infants subjected to alcohol while in the womb.

There is evidence from the history, physical examination, or laboratory findings that deficits are etiologically related to the persisting effects of substance use.There are problems with DSM diagnostic criteria. Furthermore, the criteria for diagnosis of dementia were inspired by the clinical presentation of Alzheimer’s disease and are poorly adapted to the diagnosis of other dementias.


Adding the struggles of alcohol-related dementia means family support is even more important. With family support, a person is more likely to have a lasting recovery. Individuals with alcohol-related dementia generally have issues with their memory. For example, they may struggle to understand new information or details of a conversation.

Alcohol can have both acute and chronic effects on cognitive functions. Acute cognitive impairment can be seen in direct intoxication which impairs most cognitive skills and in excess, may lead to respiratory depression and stupor. Long-term alcohol use may result in amnesia and difficulty in recall . Oslin refined the diagnostic criteria for ARD by including duration and severity of alcohol consumption and a minimum abstinence time, for a ‘probable’ diagnosis of ARD to be considered. He expected this classification would bring more clarity and stimulate further research in this area . Even till now, only a few studies have adopted these criteria and they still need research for being conclusive (13-15).

The first problem is the most glaring, and that’s the addict themselves. Behaviors can be unpredictable and uninhibited, and communication is difficult and could become impossible. Medically Reviewed By Benjamin Caleb Williams, RNA licensed behavioral health or medical professional on The Recovery Village Editorial Team has analyzed and confirmed every statistic, study and medical claim on this page. Alcohol use disorders have long been known to carry a long list of health issues. Of the dementia cases, around 3 percent were directly attributed to alcohol. But when the team looked at only the early-onset dementia cases, the percentage was much higher. Certain risk factors — such as aging, smoking, and depression — are already known, but the role of alcohol has proven more difficult to pin down.

  • They may fall over because alcohol damages the part of the brain that controls coordination and balance.
  • This heterogeneity in outcome operationalization may have contributed to the contradictory findings with respect to light to moderate drinking mentioned above.
  • It’s hard to know what to say to a loved one when you’re worried that their drinking is affecting their health.
  • Examining a person’s nervous and muscular system can help shed light on any nerve damage caused by alcoholic dementia.
  • The Wernicke’s encephalopathy is an acute neurological disorder, precipitated by thiamine deficiency, characterized by the clinical triad of ophthalmoplegia, ataxia and confusion.

This study extends our knowledge about the well known J-shaped curve of the effects of alcohol on mortality, to look at the effects of alcohol on cognitive function in older adults. The study is careful not to suggest that older adults should drink, but the data are important. Direct intoxication impairs most cognitive skills and in excess may lead to stupor and respiratory depression. Acute withdrawal in long-term alcohol abusers can result in tremor, hallucinations, seizures, agitation, and fluctuating levels of alertness . WKS is classified in the DSM-IV as ‘alcohol-induced persisting amnestic disorder’, and memory disturbance is the key diagnostic feature . Dementia is a clinical syndrome characterized by a progressive deterioration in cognitive ability and the capacity for independent living and functioning .

Neither informed consent to participate nor ethical approval is required. JR and OSMH performed the main systematic searches and the methodological studies to assure inter-rater reliability. JR wrote a first draft of the paper, and all authors participated in revising the draft to its current form and approved the final version. Alcohol use was always self-reported and in almost all studies was assessed only once, at baseline . These accreditations are an official recognition of our dedication to providing treatment that exceeds the standards and best practices of quality care. At North Jersey Recovery Center, we strive to make your addiction treatment experience as comfortable as possible.

Protective Effects

Among the 1,518 participants screened, late-onset alcohol abuse affected 2.2 percent, higher than the 1.7 percent for older adults overall. They also found that alcohol abuse as a first symptom occurred in 1.4 percent of all patients, five times more frequently in patients with bvFTD than those with Alzheimer’s-type dementia. The results indicate not only that late-onset alcohol abuse is much more frequent in bvFTD than Alzheimer’s-type dementia, but also the likelihood that the biological mechanisms underlying late-onset and lifelong alcohol abuse are different. The presence of alcohol abuse was screened using the National Alzheimer’s Coordinating Center UDS questionnaire completed by clinicians during patient research visits.

The differing elements of drinking patterns as well as difficulties gaining an accurate self-report of past drinking have further complicated attempts to link drinking levels to later cognitive impairment. Estimates of past drinking habits of individuals diagnosed with ARD have included up to 60 years of drinking , although there is significant variability in length and severity of drinking . Oslin and colleagues suggested that a five-year history of consuming 35 standard drinks a week for men and 28 for women constitutes a sufficient level of neurotoxic burden to risk the development of ARD, but this needs verification. Recent research indicates that alcohol plays a much larger role in early-onset dementia than previously thought.

Therapies For Dementia And Alcoholism

Another form of ARD is known as wet brain (Wernicke–Korsakoff syndrome), characterized by short-term memory loss and thiamine deficiency. ARD patients often have symptoms of both forms, i.e. impaired ability to plan, apathy, and memory loss.

Social isolation appears to be a significant factor in the poor identification and treatment of ARD, and a high proportion of patients are unmarried or do not have the support of family or friends . These gender and social findings are consistent with reported characteristics of individuals who are heavy users of alcohol . This type of dementia is called alcohol-related brain damage, abbreviated as ARBD. Middle-aged Americans are considered to be the most at-risk, since younger people tend to experiment with other drugs rather than drink heavily. While women are more susceptible to the effects of alcohol, men receive more diagnoses for ARBD than women, possibly due to the higher amounts of the substance consumed throughout their lives. Typically, alcohol-related dementia affects men over 45 struggling with chronic alcoholism.

Associations Between Dimensions Of Alcohol Use And Specific Brain Functions

Reports also suggest that mild structural changes can result even with subclinical thiamine deficiency. Animal models suggest similar brain changes in direct alcohol neurotoxicity and those produced by thiamine deficiency. These changes include shrinkage of frontal brain volume, loss of cells in the basal forebrain and hypofunction of hippocampal acetylcholine. Thiamine deficiency also showed lesions in the diencephalon, which were not present in direct alcohol neurotoxicity . However, other pure cases of thiamine deficiency , without chronic and excessive alcohol consumption, show a low rate of progression to KS . This further supports the notion that cognitive deficits seen in ARD are multifactorial.

  • Another hypothesis is that thiamine deficiency is primarily responsible for the development of ARD.
  • Those who drink heavily are statistically more likely to injure themselves – and their brains – through falls or fights.
  • This scoping review was limited by the large amount of heterogeneity in the operationalization of outcomes and the small degree of overlap of underlying studies between reviews .

Other types of alcohol-related brain damage occur outside of direct, damaging interactions between alcohol and brain cells. Those who drink heavily are statistically more likely to injure themselves – and their brains – through falls or fights. Also, damage to other parts of the body will affect the brain over time.

Alcohol Misuse Increases Early

When Wernicke’s syndrome is not treated correctly, the result is Korsakoff psychosis. If your healthcare provider has advised you to stop drinking entirely, it’s important to follow their advice.

A person’s weight, gender, metabolism, and genetic predisposition are also factors. Overall, patients with alcohol dependence, or AUD, often lack insight into their condition, are ashamed, isolated, and, in many cases, lack access to proper healthcare. If you find our articles and interviews helpful, please consider becoming a supporting member of our community. Frustrated by the lack of an editorially independent source of information on brain health and Alzheimer’s disease, we decided to create Being Patient. We are a team of dedicated journalists covering the latest research on Alzheimer’s, bringing you access to the experts and elevating the patient perspective on what it’s like to live with dementia. To develop alcohol abuse interventions specifically for people with dementia.

Assessing Alcohol Abuse And Alcohol

Since they can’t make sense of things, situations can quickly escalate into violence where they might hurt themselves or others. For example, a person with dementia might not remember what food is for or how to use a spoon. Wernicke encephalopathy can progress into Korsakoff if left untreated. However, Korsakoff syndrome may also occur independently or simultaneously with Wernicke. Can I suggest that instantly cutting off alcohol to a dependent drinker can be fatal. There are now non-alcoholic versions of most popular beers eg Budweiser, Heineken available.

Creutzfeldt-Jakob Disease is a form of a brain disorder known as prion diseases and is the most common form of this disorder. The syndrome can get to the point where patients begin to make up information that they can’t remember on their own. However, this doesn’t quite mean they are lying, some of these people may even believe these fabricated situations. Wernicke encephalopathy can alcoholism cause dementia is a related disorder that often precedes Korsakoff syndrome. If left untreated, it can cause death in up to 20 percent of cases and progresses to Korsakoff syndrome in 85 percent of survivors. Data suggests that about 25 percent of those who develop Korsakoff syndrome eventually recover, about have improve but don’t fully recover, and about 25 percent remain unchanged.
