Bowden et al. remarked that it would be more apt to describe the chronic phase of WKS as ‘dementia-like deterioration’/ARD rather than severe and selective amnesia (53). Having comparatively spared implicit and procedural memories, patients typically have profound antegrade amnesia and impaired recall, with recall being better for more remote events (54, 55). In around 80% of the patients suffering from KS/ARD, executive deficits have been identified, mostly in the tasks assessing planning, higher-order organization, and cognitive flexibility (56, 57). As a carer for her mum, who has vascular dementia, Clare is taking part in our ‘We live with dementia’ campaign to make more people aware of the support our nurses offer.

The results will help determine whether you or your loved one has AUD, dementia, or both.

Because he is a member of a support group that stresses the importance of anonymity at the public level, he does not use his photograph or his real name on this website. ARD is a progressive illness, which means its symptoms often happen in stages and continue to get worse—especially if left untreated. The most distinguishing symptom is confabulation (fabrication) where the person makes up detailed, believable stories about experiences or situations to cover gaps in memory. After several years of erratic behavior and speculation, reps for Wendy Williams revealed she was diagnosed with dementia and aphasia in 2023.

Long-term outcomes of WE can include development of a syndrome of profound memory impairment – Korsakoff syndrome (KS) – that appears to be related to additional disruption to diencephalic and hippocampal circuitry. As KS shares similar pathological substrates and often follows an episode of WE, it is commonly referred to as the Wernicke-Korsakoff syndrome [1]. Increasing evidence suggests that the WKS encompasses a spectrum of pathological, neurological, and cognitive impairments resulting from thiamine deficiency [4]. The heterogeneity in presentation of the WKS, in combination with a lack of distinct pathological evidence for ARD, has led to the suggestion that cases of ARD are variants of the WKS [20].

In particular, drinking patterns of repeated binges and withdrawal periods may enhance neuronal injury through increased vulnerability of upregulated N-methyl-D-asparate (NDMA) receptors to glutamate-induced excitotoxicity. Support for the neurotoxicity hypothesis emerges from animal studies, which have demonstrated dose-related ethanol-induced damage to brain structures – including the hippocampus, hypothalamus, and cerebellum – that correspond with impairments in memory and learning [14,15]. Cholinergic neurotransmission in alcohol and dementia the basal forebrain, which plays a key role in attention, learning, and memory, also appears to be impacted by prolonged intake of alcohol. Imaging studies of ‘uncomplicated alcoholics’ – individuals with no history of nutritional deficiency, hepatic failure, or other indirect forms of brain injury – confirm structural abnormalities, including changes to the corpus callosum, pons, and cerebellum [12]. However, the permanence of such changes, and whether they relate to neurotoxicity in isolation, remains to be established [1].

Another important consideration for neuropathology of ARD involves WE and KS. This leads to a hypothesis that ARD is primarily due to thiamine (vitamin B1) deficiency. Also, because of poor dietary nutrition, alcohol users are at a higher risk of thiamine deficiency (31). The Wernicke’s encephalopathy is an acute neurological disorder, precipitated by thiamine deficiency, characterized by the clinical triad of ophthalmoplegia, ataxia and confusion.

• Korsakoff syndrome causes confabulation, memory loss, and gait abnormalities.
• At the moment, only 2% of people with dementia can access the specialised tests needed to demonstrate eligibility for new treatments, leading to unnecessary delays, worry and uncertainty,” she said.
• Alcohol related brain damage tends to be more common in people in their 40s and 50s and comprises about 10% of the cases of young onset dementia diagnosed.
• Alcohol itself does not directly cause Wernicke-Korsakoff syndrome as much as the damage to the brain cells that takes place from a thiamine deficiency (vitamin B1) caused by alcohol.

However, efficacy of CBT depends upon the relative integrity of certain brain regions particularly frontocerebellar and preserved cognition (80). Thus, CBT cannot be effectively employed where cognition is severely impaired particularly memory and executive function (81-83). Oslin refined the diagnostic criteria for ARD by including duration and severity of alcohol consumption and a minimum abstinence time, for a ‘probable’ diagnosis https://ecosoberhouse.com/ of ARD to be considered. He expected this classification would bring more clarity and stimulate further research in this area (12). Even till now, only a few studies have adopted these criteria and they still need research for being conclusive (13-15). The person who is drinking alcohol to excess should see their GP for an assessment of the issue and for referral for treatments and services available to treat the alcohol misuse.
