Over time, excessive alcohol consumption increases a person’s risk of AD by 300%. Below, we lay out the effects of alcohol on the brain and identify the specific drinking behaviors that research says put individuals at the greatest dementia risk. These figures differ widely depending on factors such as the severity of the condition, the presence of other health complications, and whether the individual stops drinking alcohol and receives early intervention. On average, life expectancy oscillates from several years to a decade, with men experiencing a slightly shorter lifespan in comparison to women.
How alcohol might damage the brain
If a person with ARBD stops drinking alcohol and receives good support, they may be able to make a partial or even full recovery. They may regain much of their memory and thinking skills, and their ability to do things independently. But these effects can be slowed — and sometimes reversed — if you stop drinking. A 2023 study found that people diagnosed with depression were more than twice as likely to be diagnosed with dementia later in life.

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. According to the Dietary Guidelines for Americans 2020–2025, drinking in moderation consists of no more than one or two drinks daily for females and males, respectively. A standard drink contains 14 grams, or 0.6 ounces (oz), of pure alcohol in the United States. Research suggests that almost half of dementia cases worldwide could be prevented or delayed. If everyone cut down on alcohol, there’d be one fewer case of dementia for every 100 people who develop it now.
Damage to blood vessels
Heavy alcohol use can also lead to a condition called hepatic encephalopathy, characterized by a loss in brain function due to increases of ammonia https://ecosoberhouse.com/ in the blood caused by liver damage. First, ethanol and its byproduct acetaldehyde are known to have a toxic effect on the brain that can lead to long-term structural and functional brain damage, Schwarzinger says. Diagnosis for alcohol-related dementia requires a physical and mental health exam, blood testing, and a thorough health history.
Does Treatment Reverse Alcoholic Dementia?
- Regularly drinking too much alcohol damages blood vessels in a person’s brain and can lead to high blood pressure.
- It isn’t easy to cope with alcohol-related dementia, but there are resources that can help.
- Middle aged women are more at risk of the negative effects of alcohol due to differences in hormones, body fat composition and height weight ratios.
- You can also use their online chat feature for more personalised advice, including a self-assessment.
It’s no secret that heavy drinking can hurt your mental and physical health in the long run. But some experts say the lifestyle habit may be more harmful than anticipated — especially when it comes to the brain. Heavy drinking can lead to cognitive impairment, and in severe cases it can cause «alcohol-induced dementia,» says Amber Robins, MD, a double board-certified family and lifestyle medicine physician. The person who is drinking alcohol to excess should see their Halfway house GP for an assessment of the issue and for referral for treatments and services available to treat the alcohol misuse.
- In addition, if the GP suspects that there may be cognitive damage they may refer the person for an assessment of the cognitive damage and for ongoing support if needed.
- Moreover, alcohol’s neurotoxic effects damage brain cells and disrupt neural communication pathways, exacerbating cognitive decline.
- We’re not saying that this is happening for everyone who develops this, but it is possible that the drinking is the result of a medical condition that they don’t really have any control over.
This is known as alcohol-related brain damage (ARBD) or alcohol-related brain injury (ARBI). Some people with ARBD will only have small changes to their thinking and can drinking cause dementia memory, known as mild cognitive impairment (MCI). Research suggests that a history of drinking 28 alcoholic beverages a week for women or 35 for men increases the risk of developing alcohol-related dementia, according to the journal Alzheimer’s Research and Therapy. Several high-profile reviews looked at the research into alcohol and dementia risk.
What Is Alcohol-Induced Dementia?
You can find out how many units are in an alcoholic drink by reading the label. This should ideally be spread over three or more days because ‘binge-drinking’ is particularly harmful to the brain. Research has found that untreated vision loss increases the risk of dementia by about 50 percent, so go to the eye doctor when you can. Research has found that lowering blood pressure in people with hypertension can lower the risk of dementia by about 15 percent. Smoking has been linked to dementia because it can increase the risk of problems with the heart and blood vessels, the Alzheimer’s Society says. Toxins in cigarettes also cause inflammation, which has been linked to Alzheimer’s disease.
