There was no evidence of a relationship between alcohol use and dementia in females when the models were fully adjusted and when the model adjusted for competing risk of death. This research aimed to investigate the relationship between PA and the onset of cognitive impairment. Adults who engage in at least 150 min of LPA per week, spread over 3 or more days, or at least 30 min per session, exhibit a lower risk of cognitive impairment compared to inactive individuals.
Cohort Studies
Drinking alcohol in moderation has not been conclusively linked to an increased risk of dementia. If you already drink alcohol within the recommended guidelines, you do not need to stop on the grounds of reducing the risk of dementia. Learn how drinking too much alcohol can damage the brain and increase a can alcohol cause dementia person’s risk of developing dementia. A vitamin B1 deficiency resulting from excessive alcohol consumption may also cause Wernicke-Korsakoff syndrome, rather than the disorder being a direct result of alcohol misuse. A 2020 study showed that moderate alcohol intake could lower a person’s risk of developing Alzheimer’s disease.
Maintaining low cholesterol may help decrease dementia risk
- Stanford Medicine is an integrated academic health system comprising the Stanford School of Medicine and adult and pediatric health care delivery systems.
- In this study, we aimed to investigate the relationship between the age at onset of depression and AD risk, and compare the characteristics between different age groups.
- Although numerous studies have explored the relationship between PA, cognitive impairment, and potential cognitive impairment in middle-aged and older adults 24, 27, the majority of these studies have utilized a cross-sectional design.
- A small number of studies seem to suggest that drinking moderate amounts of alcohol reduces dementia risk compared to not drinking at all.
- Preventive Services Task Force, current estimates are that fewer than 50% of people who visit primary care providers for alcohol-related issues are asked about the problem.
- Prior knowledge of the recall day was not provided to the participants, ensuring that they did not alter their dietary habits in anticipation of the interview.
Importantly, studies of the alcohol–dementia relationship are largely based on samples from high‐income countries 9, 10. Evidence for the relationship between alcohol use and dementia is sparse in low‐ to middle‐income countries, where the future burden of dementia is likely to be concentrated 3, and where Substance abuse alcohol use is increasing 12. We used a two-sample Mendelian randomization (MR) approach to evaluatedthe causal relationship between alcohol intake and AD.

Excessive alcohol may compromise executive functions in people with dementia and can lead to memory, learning, problem-solving, and judgment problems. Individuals may also be irritable, have sudden outbursts, and have issues with coordination and balance. Long-term alcohol use may lead to Alzheimer’s disease (AD), a type of dementia that affects more than six million Americans. And although the likelihood of having dementia also increases with age, it is not a typical part of aging. Around one in six American adults drink to excess, and almost half of the United States population drank alcohol in 2020. Excessive drinking can cause long-term effects such as stroke, heart disease, and cancer.
In total, more than 5,000 articles were considered; approximately 400 are referenced herein (i.e., only articles directly related to search terms were included). People with LDL-C at 55 mg/dL had only 18% risk reduction, and below 30 mg/dL, there was no reduction in dementia risk at all. A new study by South Korean researchers has found that people with low, but not extremely low, LDL-C levels have a reduced risk of developing dementia, and this decrease appears to be enhanced if they take cholesterol-lowering statins. Find out about alcohol-related dementia including symptoms, diagnosis, treatment and support. If you regularly drink much more than this, you are increasing your risk of damage to your brain and other organs, and so increasing your risk of dementia.
Elevated Dopamine in Cannabis Users May Explain Psychosis Risk
- To mitigate this issue, we cross-referenced patient and caregiver reports with available medical records to enhance data accuracy.
- During follow-up, the antidepressant treatment response and remission were assessed using the HAM-D score.
- If depression in older adults had a greater impact on cognitive function regardless of initial onset, we would expect recurrent depression later in life to be a significant dementia risk factor.
- Previous studies have shown that the WW exercise pattern can suppress inflammatory processes and enhance antioxidant capacity, helping to prevent depressive-like cognitive and behavioral changes 33.
- However, our multivariable analysis did not support this, as late-life recurrent depression (indicated by “multiple tendency”) did not independently increase dementia risk beyond the age of depression onset (Table 2).
Reported a mean depression onset in the mid-to-late 50s, with few patients whose depression began after the age of 75 years. Since depression onset after age 75 constitutes a very small subset of the overall depression population, its unique characteristics may not have been fully captured in studies focusing on earlier-onset cases. This could help explain why depressive symptoms in later life might have a different association with dementia risk than earlier-onset depression, further emphasizing the need for onset-age-specific analysis to understand the link between depression and dementia.
- Furthermore, when accounting for all-cause mortality as a competing risk using the Fine and Gray hazard model, similar results were observed (Supplementary eTable 6).
- If further confirmed, the new findings suggest that a preventive intervention for dementia is already close at hand.
- In the absence ofany therapeutic interventions for dementia, successful intervention strategies thattarget modifiable risk factors to promote disease prevention are currently the onlyavailable approach that can have an impact on the projected rates of dementia.
- Dementia affects memory, thinking, behavior, and the ability to perform everyday activities 2, and is a leading cause of disability in older individuals 3.
- These analyses were conducted with the coxme package in R and included the binary drinking frequency variable (daily drinking/not daily drinking) while adjusting for age, sex, smoking status and baseline alcohol consumption (g/day), as well as cohort as a random effect.
Other factors that have links to the development of dementia may include infections, such as HIV or neurosyphilis, or thyroid disorders. If you suspect you have this condition, reach out to a healthcare professional as soon as possible to discuss treatment options. If you think you may be experiencing alcohol-related dementia, talk with a healthcare professional. Despite this, there may be other characteristics such as social activity that could drive the apparent protective effect of alcohol against dementia, rather than alcohol use per se.
