There may be a link between alcohol and dementia, but its complicated
The observational epidemiological studies underlying the reviews listed in Table 1 were limited because the majority of the studies were restricted to older populations (that is, late adulthood). Of the 350 results from the original search, a total of 28 systematic reviews, most of which were published after 2010 [11, 20, 22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47], met all inclusion criteria.

Importance
The impact of serial changes in alcohol consumption on dementia risk has rarely been investigated to date. JR and OSMH performed the main systematic searches and the methodological studies to assure inter-rater reliability. JR wrote a first draft of the paper, and all authors participated in revising the draft to its current form and approved the final version.
Other causes of dementia
Research studies show that’s especially the case with colorectal cancer — ranked eighth in incidence among all states — and breast cancer, ranked ninth. The study found that individuals who regularly over-consumed were three times more likely to develop a dementia as those who did not. Over-consumption of alcohol was especially common in study participants diagnosed with early-onset dementia or Alzheimer’s disease. • The study found that while moderate consumption was actually linked to a slight decrease in Alzheimer’s disease, regular over-consumption of alcohol increases the risk of developing Alzheimer’s disease by 300%.
- The hazard ratio for abstinence compared to consumption of 1–14 drinks per week for developing any kind of dementia was 1.47, after adjusting for confounders (extensive assessment of sociodemographic data and cardiovascular health data).
- It is essential to identify modifiable risk factors as understanding these could help prevent or delay the onset of dementia.
- Around one in six American adults drink to excess, and almost half of the United States population drank alcohol in 2020.
- Among the 25 counties in the U.S. with the highest incidence of cancer, Iowa’s Palo Alto County ranks second.
This article describes the causes of alcoholic dementia, symptoms, diagnosis, treatment, and coping. If you or a loved one begins to develop signs of alcoholic dementia, it’s important to see a healthcare provider as soon as possible. Medical treatment and getting treated for alcohol addiction may help prevent the condition from getting worse. “That is what really sets this paper apart — we can assess the association between dental health and cardiovascular and brain health independent of any confounding from socioeconomic status,” Trumble said. PTSD has been linked with poorer performance on neurocognitive tasks, including attention, memory, processing speed, verbal learning, and executive functions. PTSD appears to be another pathway to dementia or, more appropriately, neurocognitive disorders (NCD), which includes Alzheimer’s Disease and other forms of dementia.
Alcohol and Your Brain: The Latest Scientific Insights
The interplay between cortisol dysregulation, heightened norepinephrine levels, and structural alterations in key brain regions make some individuals more susceptible to PTSD than others. Humans have a longer lifespan these days, so there are more people living into their 70s and beyond—which has also provided the opportunity to look at alcohol and dementia alcohol and dementia in more detail. By examining the differences between alcohol-related dementia and more common forms, such as Alzheimer’s Disease, we begin to see that they are different in many ways. For example, the problems with word-finding seen in Alzheimer’s Disease is rarely seen in alcohol-related dementia, which also presents much earlier with changes in behavior.

Conversely, other recent data suggest a lower risk for dementia in people consuming a few alcoholic beverages a day. This includes a 2022 study showing that in around 27,000 people, consuming up to 40 grams of alcohol (around 2.5 drinks) a day was https://ecosoberhouse.com/ linked to a lower risk for dementia versus abstinence in adults over age 60. A much larger study of almost 4 million people in Korea noted that mild to moderate alcohol consumption was linked to a lower risk for dementia compared to non-drinking.
Alcohol and Alzheimer’s Disease
Wernicke-Korsakoff syndrome occurs due to a deficiency in vitamin B1 or thiamine. This is a common deficiency in people who misuse alcohol, but it can also occur due to other disorders or conditions. Experts noted that France, well known for wine consumption, has an average 0.4% rate of alcohol-related dementia.
