Specifically, adjustments were made for age, gender, ethnicity, Townsend deprivation index, education level, employment status, alcohol consumption, smoking, BMI, and baseline comorbidities (including cardiovascular disease, hypertension, and diabetes). The proportional hazards assumption was checked using Schoenfeld residuals, and no violations were detected. Calculating the hazard ratio (HR) for each value of the covariate, the location where the HR approaches 1 can be identified, which corresponds to the threshold. Data utilized in this study were obtained from the Aiginition Longitudinal Biomarker Investigation of Neurodegeneration (ALBION) population-based cohort study. This study is conducted at the Cognitive Disorders Clinic of Aiginition Hospital, affiliated with the National and Kapodistrian University of Athens.
- Poisson regression analysis was employed to explore the relationship between PA parameters and the incidence of cognitive impairment over four years.
- They’ll likely start by doing a physical exam and asking about your physical and psychological symptoms.
- The symptoms of alcohol-related dementia and age-related dementia are fairly similar.
- To address this, we conducted a longitudinal study of a hospital cohort of patients with depression, with up to 22 years of follow-up to examine the relationship between age at onset of depression and dementia risk.
Rodent models of AUD and Alzheimer’s disease
For individuals with alcohol addiction, the progression of dementia may occur more rapidly and at an earlier age compared to those without this addiction. Alcohol-related dementia, also known as alcohol-induced dementia, can manifest as a distinct form of dementia or exacerbate pre-existing forms, such as Alzheimer’s disease. Alcohol addiction, also known as alcoholism or alcohol use disorder (AUD), is a chronic condition characterized by the compulsive and uncontrollable consumption of alcohol, despite negative consequences. It is a complex disorder that affects both physical and mental health, often leading to significant impairment in various areas of life. A small number of studies seem to suggest that drinking moderate amounts of alcohol reduces dementia risk compared to not drinking at all.
Impact of Alcohol Addiction on Brain Health
The researchers emphasize that their observational study cannot show the direction of the relationship between excessive sleep and dementia. The authors of the study state that higher levels of LDL-C lead to inflammation, oxidative stress and an imbalance in brain cholesterol homeostasis, all of which are implicated in the development of dementia. People with LDL-C levels below 70 mg/dL had a 26% lower risk of Twelve-step program all-cause dementia and a 28% lower risk of Alzheimer’s disease related dementia, than those with LDL-C levels greater than 130mg/dL.

According to a WHO statement, it has been asserted that there is no safe level of alcohol consumption regarding human health. Nevertheless, the relationship between alcohol consumption and Alzheimer’s disease (AD) pathology remains unclear. Therefore, we examined whether the frequency and patterns of alcohol consumption could predict neurodegeneration biomarkers in a cohort of middle-aged adults without dementia.
- They all found that people who drank heavily or engaged in binge drinking were more likely to develop dementia than those who drank only moderate amounts.
- Beverage type was not consistently assessed across the cohorts and therefore could not be considered in the current study.
- Discover 4 important things about relapse, including triggers, aftercare, and support for lasting recovery.
- In conclusion, addressing alcohol addiction, managing dementia symptoms, and adopting an integrated approach to care are essential components of the overall treatment and management strategies for individuals facing the complex relationship between alcohol addiction and dementia.
We examined associations of dementia with alcohol consumption in midlife, alcohol dependence, hospital admission for alcohol related disease, and trajectories of alcohol consumption over 17 years. In addition, we examined whether cardiometabolic disease modifies the association between alcohol consumption and dementia. Analyses first focused on the categorical alcohol use variable and were conducted in the full sample with current abstainers as the reference category. All analyses were then repeated in the sample of 11 cohorts where life‐time abstainers and former drinkers could be separated, with life‐time abstainers as the reference category. These analyses included inverse probability of censoring weights and were adjusted for age, sex and smoking status, as well as a random effect for cohort using the coxme package in R 31.
- Frequency of alcohol use is likely to be an important factor in dementia risk, but the current study was limited in the way it could examine alcohol frequency across cohorts.
- The current study addresses these limitations by harmonizing individual participant‐level data from 15 prospective epidemiological cohort studies, including representation from countries situated throughout six continents, and examining the alcohol–dementia relationship.
- While light or moderate drinking may protect against the development of Alzheimer’s disease, chronic alcohol use over an extended period can cause irreversible brain damage.
- As the MVPA threshold increased, the association between the WW group with short SB time and a lower dementia risk gradually lost statistical significance.
- While the current study was able to account for many demographic and clinical characteristics which were harmonized across cohorts, uncontrolled confounding may still impact this study’s results.
- We specifically compared patients with depression onset before the age of 55 years and those with depression onset at or after the age of 75 years, as these groups exhibited the most significant differences in dementia risk.
In the second part, we will present the results of a systematic literature search we conducted. We will then address can alcohol cause dementia the question whether alcohol consumption constitutes a potential target for dementia prevention. When compared with abstainers, the risk for dementia was lower in occasional, light–moderate and moderate–heavy drinkers (Table 3). Similar relationships were found in the fully adjusted model and competing risk model, as well as in the subsample of males. For women, the unadjusted model showed that, when compared with abstainers, the risk for dementia was lower in occasional, light–moderate and moderate–heavy drinkers.
