Excessive drinking can cause long-term effects such as stroke, heart disease, and cancer. Patients with ARD and WKS have shown cognitive improvement following treatment with memantine, although these findings require replication [68,69]. Finally, these socially isolated patients are often hospitalized for another health condition and this presents an ideal opportunity for screening, identification, and intervention.
- Thus, CBT cannot be effectively employed where cognition is severely impaired particularly memory and executive function (81-83).
- This is because alcohol damages the part of the brain that controls balance, co-ordination and posture.
- JR and OSMH performed the main systematic searches and the methodological studies to assure inter-rater reliability.
If you have difficulty controlling your alcohol use and want help, there are many treatment options and resources to help you through your journey toward sobriety and wellness. For instance, research suggests that a five-year history of drinking 35 alcoholic beverages a week for men and 28 for women presents a “sufficient” risk for the development of ARD. For doctors out there, when you see patients who have late-onset alcoholism, which is defined as happening after the age of 40 or older, perhaps these people need a little more attention and an evaluation for a neurologic disorder. We’re not saying that this is happening for everyone who develops this, but it is possible that the drinking is the result of a medical condition that they don’t really have any control over. People may have these accumulated risks, but they may have genetic or environmental factors that have a protective effect, and they never experience cognitive decline related to alcohol use. Those same factors, along with other health conditions, may put them at greater risk.
Midlife alcohol consumption
Moderate alcohol drinking is classified as drinking one alcoholic drink a day for women and two a day for men. Light drinking describes those who drink less than moderate drinkers but more than those who totally abstain from alcohol. Find out about alcohol-related dementia including symptoms, diagnosis, treatment and support. https://ecosoberhouse.com/ You may need to stop drinking while being treated in an inpatient program if you regularly consume excessive alcohol. Therapy for alcoholic dementia can include management of AUD, nutritional supplementation to compensate for nutrient deficiencies, and exercises to help improve cognition (thinking abilities) and motor skills.
A 2020 study showed that moderate alcohol intake could lower a person’s risk of developing Alzheimer’s disease. The neuropsychology of WKS has been the subject of more extensive investigation. Patients typically demonstrate profound anterograde amnesia and impaired recall of past events, with a temporally graded deficit in which recall is better for more remote time periods [58]. Other cognitive functions apart from memory may be disturbed, and impaired executive functions, visuoperceptual difficulties, and disturbed working memory have been observed [59]. Difficulties are most frequently detected on tasks assessing higher-order organization, planning, and cognitive flexibility (for example, verbal fluency and divided attention) [60,61]. In a review of evidence for variability in WKS, Bowden [4] remarks that empirical evidence suggests that the chronic phase of WKS is more accurately described as ‘dementia-like deterioration’ rather than severe and selective amnesia.
Alcohol-Related Dementia and Neurocognitive Impairment: A Review Study
Elderly alcoholic dementia is a closely-related condition which affects elderly people, and the health effects of alcohol are worse when coupled with other neurological illnesses such as Alzheimer’s disease or Parkinson’s disease. This combination of brain issues might be incurable and are known as alcohol-induced psychosis. There are several symptoms which can be easily identified and might indicate that one suffers from this health problem.
- Wernicke-Korsakoff syndrome can occur due to other conditions, but misuse of alcohol is a common underlying factor for its development due to long-term vitamin deficiency.
- A new publication from the Whitehall study confirms earlier findings that light to moderate alcohol drinkers have a reduced risk of dementia compared with abstainers and heavy drinkers.
- He expected this classification would bring more clarity and stimulate further research in this area (12).
- The doctor will also do a full physical examination and take a detailed history of the person’s symptoms and how they are affecting their life.
The age of onset of alcohol-related dementia varies, but it’s often seen in middle-aged adults around 40 to 50 years old. However, it can occur earlier or later depending on the amount of alcohol a person consumes. While forgetfulness and short-term memory might be the first signs, a person may go on to experience difficulties with executive functioning (like organizing and planning) and, in a later stage, problems with motor abilities.

So skipping five days of drinks doesn’t mean you can safely have five drinks in one 24-hour period — it’s still only one. Thousands of people across the UK who are worried about their memory will receive blood tests for dementia in two trials that doctors hope will help to revolutionise the low diagnosis rate. In some cases, Martinez said, it may even contribute to memory impairment or even play a role in a neurological disorder.
They showed that this brain network is also particularly vulnerable to schizophrenia and Alzheimer’s disease. Yuko Hara, PhD, the director of aging and Alzheimer’s prevention at the Alzheimer’s Drug Discovery Foundation, further explains why some factors heighten dementia risk and suggests ways to reduce them. In previous research, the scientists had pinpointed a “weak spot” in the brain — a specific network of higher-order regions that not only develop later during adolescence, but also show earlier degeneration later in life. They discovered that this brain network is particularly vulnerable to schizophrenia and Alzheimer’s disease. After the first part of treatment, a person with alcohol-related ‘dementia’ will need support from different kinds of services. They may be treated with drugs that mimic the effect of alcohol on the brain to reduce withdrawal symptoms.
Alcohol use and dementia: new research directions
The Korsakoff syndrome is a long-term outcome of WE and includes a syndrome of profound memory impairment, which is related to additional disruption to diencephalic and hippocampal circuitry. Because of similar pathological substrates, WE and KS are commonly referred to as the Wernicke-Korsakoff syndrome (WKS) (2). Patients with WKS demonstrate similar but more severe lesions in form of deficits in regional brain volumes (mammillary bodies, thalamus, cerebellar hemispheres, and vermis) than alcoholic patients without WKS (47). There have been suggestions that cases of ARD are variants of the WKS due to combination of heterogeneity in presentation of the WKS along with a lack of distinct pathology for ARD (50). Other reports suggest that ARD and WKS are distinct disorders with overlapping clinical profile (24).
Cognitive impairment predicts poor compliance with treatment and decreased self-efficacy. Cognitive impairment also influences the degree of motivation, which is an essential prerequisite for effective management. Thus, cognitive dysfunction influences management by determining the efficacy of treatment and the prognosis. Every patient with alcohol alcohol and dementia dependence should be advised to strive for total abstinence. In cases with cognitive impairment, memory training techniques along with social support is required. Due to the damage caused by alcohol metabolism coupled with thiamine deficiency, adequate thiamine transport is affected at various sites including the blood-brain barrier.
