Studies have shown that excessive alcohol use can lead to many health problems such as dementia and cognitive decline, particularly among older people. While researchers are still learning about the link between drinking and dementia, it is important to act now to raise awareness of alcohol consumption as a risk factor. In recognition of National Aging Life Care Month, this post will explore the link between heavy drinking and dementia, as well compare and contrast alcohol consumption in the United States and South Africa, two countries that rank high among heavier-drinking nations. The goal is for aging professionals to explore how different cultures can prevent cognitive decline.
Alcohol-related dementia (ARD), a form of dementia caused by long-term, heavy drinking, leads to neurological damage and impaired cognitive function. Binge drinking typically occurs after four drinks for women and five drinks for men-in about two hours, according to the National Institute on Alcohol Abuse and Alcoholism. Despite steps to address dementia in South Africa, there is still no national plan that deals with the risks associated with alcohol use. The U.S. has several organizations, such as the Alzheimer’s Association, which provide interventions to reduce alcohol-related cognitive decline.
According to the World Health Organization (WHO), South Africa has the highest level of alcohol consumption in Africa per capita. This is most alarming since South Africa has been highlighted as the worst country in the world for drunk driving, where about 58 percent of road deaths are related to alcohol consumption. WHO also places the U.S. and South Africa both among the top countries in terms of per capita alcohol consumption.
In 2015, the National Institute for Health and Care Excellence released recommendations for preventing or delaying the onset of health problems, including dementia. High on the list was the recommendation that people between the ages of 40 and 64 to “reduce the amount they drink as much as possible.” As dementia rates continue to increase in the U.S. and South Africa, it is important that aging professionals raise awareness of the causal relationship between heavy drinking and dementia.
Alzheimer’s disease (AD) is the most common cause of dementia and may contribute to 60 percent to 70 percent of cases. It is the sixth-leading cause of death in the U.S. and an estimated 5.5 million Americans currently suffer from AD. If current population trends continue, the number of people with Alzheimer’s disease will increase significantly, unless the disease can be effectively treated or prevented. Due to increases in longevity, dementia is one of the most common diseases among older people. It is also a leading cause of frailty, institutionalization and death; therefore it has a great impact on both the individual and society.
More than 2.2 million South Africans have Alzheimer’s, and many live with the stigma attached to the condition. The problem is especially acute in rural areas, where communities often think people with Alzheimer’s are ‘bewitched’ or are simply ‘acting out’. While there is no proven effective treatment nor much intervention, the consensus is that a lack of exercise, obesity and binge drinking all can increase the chance of getting Alzheimer’s.
Despite the incidence of dementia, physical activity and brain exercises have positive effects on the aging brain. Physical activity, such as brisk walking, increases the flow of oxygen to the brain. Brain exercises, such as learning a new sport or a foreign language, can set the brain cells into action and increase mental power. With studies now showing the link between heavy drinking and dementia, aging professionals in South Africa and the U.S. can discuss ways of raising awareness of aging and alcohol.
Increases in alcohol-related deaths and accidents have led to recent discussions to ban alcohol in countries and regions including Malawi and India. Globally, about 3.3 million deaths were connected with alcohol consumption in 2012. Drinking accounted for 7.6 percent of deaths among males and 4.0 percent of deaths among females. Other statistics for South Africa and the U.S. only include:
- South Africa’s average alcohol consumption is almost double the WHO African region average of six liters, and is expected to increase to 12.1 in 2025.
- More than a quarter of the drinking population in South Africa are deemed binge drinkers, consuming at least 60 grams or more of pure alcohol in one sitting within a 30-day period.
- Americans over age 60 are drinking more than they were 20 years ago.
- Alcoholism is the third leading lifestyle-related cause of death in the U.S., with 79,000 deaths per year traced to excessive drinking.
While there is plenty of evidence that chronic alcoholism can cause serious damage to the brain, it would be wise to also emphasize and encourage the benefits of other healthy habits. Many studies state that regular exercise, no smoking, healthy diets, and little or moderate alcohol intake can help reduce the risk of dementia and other cognitive decline. These lessons, including further exploration of the causal relationship between heavy drinking and dementia, call for both nations to invest more in health and wellness.
