Alcohol and Dementia What is the Link? A Systematic Review

Antipsychotic use reduced the alcohol consumption and the mortality in patients with Wernicke-Korsakoff syndrome (WKS) or ARD, and thiamine shows promise in preventing dementia in individuals with AUD. Still, further research is needed on the epidemiology and clinical presentation of ARD. Encouragingly, some individuals can improve when alcohol-related brain damage is caught early and treated appropriately. Unlike many other forms of dementia, alcohol-related cognitive decline can sometimes be halted or partially reversed if a person stops drinking and addresses nutritional deficiencies. Consistent abstinence, combined with medical and nutritional support, can help the brain regain some lost functions or adapt in ways that reduce symptoms. The diagnosis of an alcohol problem is best made by review of medical histories and interviews with patients.

Alcoholic Dementia: Causes, Symptoms, and Treatment

  • The main treatment for Wernicke encephalopathy is thiamine (vitamin B1) replacement, this is done through a vein as an infusion, rather than an injection.
  • 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).
  • The two primary classification guidelines, the International Classification of Diseases, ICD-10 (9) and the Diagnostic and Statistical Manual of Mental Disorders, DSM-5 (10) also differ in description of ARD.
  • It’s important for effective treatment and management to know these differences.
  • Among very heavy drinkers, alcohol metabolism and the resulting inflammation may even contribute to serious brain damage, possibly including shrinkage of the brain or alcohol-induced dementia, Wakeman says.
  • Rigorous testing and validation of the diagnostic criteria for ARD is required.

The induction and perpetuation of chronic, low-grade neuroinflammation represent a core shared pathological axis through which AUD critically exacerbates AD progression 18. Neuroinflammation and metabolic dysregulation play pivotal roles in alcohol-mediated AD pathology. Acute ethanol exposure significantly reduces perivascular AQP4 polarization, leading to decreased Aβ clearance efficiency, whereas chronic intake exacerbates neuroinflammation by inducing astrocytic GFAP expression 13, 19. Metabolic-immune dysregulation exhibits sex-specific differences; ethanol exposure enhances perivascular microglial Aβ phagocytic activity in aged female rats, but this effect is absent in males 20. These findings suggest that alcohol addiction exacerbates AD pathology through multidimensional molecular https://ecosoberhouse.com/ mechanisms, including E/I imbalance, glial cell polarization abnormalities, and epigenetic modifications. Integrating insights across these molecular mechanisms with the broader dysfunctions in neural circuits, networks, and clinical manifestations is essential for developing effective interventions targeting the complex AUD-AD comorbidity.

Late-stage alcoholic dementia (stage

Talk to a healthcare provider or a loved one if you’re worried you’re drinking too much. The damage that causes alcohol-related dementia happens after years of unsafe drinking. Patients with ARD and WKS have shown cognitive improvement following treatment with memantine, although these findings require replication 68,69. Finally, these socially isolated alcohol induced dementia patients are often hospitalized for another health condition and this presents an ideal opportunity for screening, identification, and intervention. If you’re worried about a friend or family member who is experiencing memory problems, confusion and/or personality changes, encourage them to visit their GP.

Tips for living with and caring for someone with alcohol-related brain damage

Alcohol exposure upregulates TLR4 expression, increasing the levels of IL-1β and TNF-α in the hippocampus, accompanied by an increase in Iba-1 positive microglial cell density 61, 62. Pharmacological intervention with sodium butyrate has been shown to significantly reduce the expression of the M1 marker CD86 and the levels of pro-inflammatory factors, while increasing the anti-inflammatory factor IL-10 61. Further studies revealed that alcohol-induced microglial secretion of MCP-1 can activate GSK3β via the CCR2 receptor, promoting neuronal apoptosis. Blocking MCP-1 synthesis (Bindarit) or CCR2 (RS504393) effectively reduces apoptotic body numbers 62. At the mechanistic level of polarization, alcohol-activated GSK3β has been found to drive microglial transition to the M1 phenotype, with minocycline significantly reducing pro-inflammatory factor release by inhibiting GSK3β activity 63.

Some of the genetic markers used for alcohol consumption are problematic as their associations with average volume of drinking and with heavy drinking occasions in overall light drinkers point in opposite directions (80; see also the discussion following 84). Furthermore, cohort studies in twins may contribute to identifying genetic variations 85. Overall alcohol abuse—classified as when alcohol consumption negatively impacts work or social life or leads to legal ramifications—is present in 1.7 percent of older adults in the United States. Previous research has identified lifelong alcohol abuse as a risk factor Halfway house for dementia.
