The scientific community maintains a cautious stance, considering these findings as preliminary. While intriguing, the connection between eye color and alcoholism requires further exploration and validation through more extensive, diverse population studies to understand the underlying biological mechanisms and potential clinical implications. In the study, researchers looked at 1,263 Americans of European ancestry, including 992 people who were diagnosed with alcohol dependence and 271 people who were not diagnosed with alcohol dependence. They found that the rate of alcohol dependence was 54 percent higher among people with light-colored eyes — including blue, green, gray and light-brown eyes — than among those with dark-brown eyes. Study co-author Dawei Li, an assistant professor of microbiology and molecular genetics, has worked with other scientists for years to build a genetic database of more than 10,000 people. All are affected by at least one mental illness, but many have multiple disorders, including depression, schizophrenia and bipolar disorder, along with alcohol or drug dependence.
Signs You May Have a Drinking Problem
An intervention from loved ones can help some people recognize and accept that they need professional help. If you’re concerned about someone who drinks too much, ask a professional experienced in alcohol treatment for advice on how to approach that person. Unhealthy alcohol use includes any alcohol use that puts your health or safety at risk or causes other alcohol-related problems. It also includes binge drinking — a pattern of drinking where a male has five or more drinks within two hours or a female has at least four drinks within two hours. Both samples showed that individuals with light-colored eyes consumed significantly more alcohol than those with dark eyes. From that extensive database, Li’s and Sulovari’s study filtered out the alcohol-dependent patients with European ancestry, a total of 1,263 samples.
Blue Eyes and Alcohol Abuse
A summary of studies performed on the efficacy of intravenous erythropoietin and high-dose corticosteroid as a medical treatment for methanol toxicity. According to the definitions in the United States, approximately 14 g of pure alcohol in any type of drink is considered as a standard alcoholic drink.[1] The containing beverage can be regular beer, malt liquor, table wine, or distilled spirits.

However, there are rare instances when eye color changes can occur during adolescence and even in adulthood. “What has fascinated me the most about this work has been investigating the interface between statistics, informatics and biology,” says Sulovari.

Li came to the University of Vermont in 2012 and has studied psychiatric genetics for a decade. Many have multiple diagnoses of diseases, including depression, schizophrenia and bipolar disorder, as well as addiction and alcohol or drug dependence. Genetic studies have identified more than 400 loci in the genome, with at least 566 variants, that could affect the risk of alcohol misuse. Certain genes, such as ADH1B and ALDH2, are predominantly involved in alcohol metabolism and are closely linked to alcoholism risk.

Still, without further studies to confirm and clarify these initial results, the scientific community remains cautious about drawing definitive conclusions. Moreover, the study participants all had at least one mental health disorder, which complicates the interpretation of the data as it suggests that the association with alcoholism could be confounded by other psychiatric conditions. But for the majority of illnesses, our genes only give us a predisposition towards diseases, affected by environmental factors. And for a disease like alcoholism, there are a huge number of non-genetic factors that can influence how and why people drink, such as social or cultural attitudes, income level, upbringing, and stress.
Does Eye Color Actually Change Over Time?
Similarly, having blue eyes may mean that a person should be more vigilant about alcohol consumption to avoid the risk of becoming alcohol dependant. Most Americans are taught that eye color is a single-gene trait – that a brown-eye gene variant is dominant over the blue-eye variant. The OCA2 gene on human chromosome 15 has a major impact on eye color by producing a protein that controls melanin formation and processing.1 The more OCA2 activity in the iris melanocytes, the darker the eye color.
Research published in the American Journal of Medical Genetics outlines genetic components that determine eye color and suggests these components are aligned with genes related to excessive alcohol use. The exploration of genetic factors, including eye color, in relation to alcoholism suggests a complex interplay between genetics and environmental influences. While studies indicate a startling correlation between blue eyes and a higher risk of alcoholism, it’s crucial to approach hope house boston review and compare with eco sober house these findings with caution, understanding that they represent only a single piece of a multifaceted puzzle. The University of Vermont study, though groundbreaking, points out that further research is necessary to confirm these associations and understand the underlying mechanisms. In this article, we present a review of ocular conditions related to alcohol consumption. PubMed, ISI Web of Knowledge database, Scopus, Embase, and the Cochrane Library were searched.
Theories suggest that for certain people drinking has a different and stronger impact that can lead to alcohol use disorder. In the future, the researchers hope to pursue more connections between genetic background and mental illness. But if you’re concerned about the genes behind alcoholism, for now you might do better to consider your own family history of alcoholism than your eye color. As it turns out, the genetic components that determine eye color line up along genes related to excessive alcohol use, the study authors explained. Using the database, the researchers identified over 1,200 people with European ancestry who suffered from alcohol dependence.
- Moreover, understanding the genetic basis of alcoholism can lead to the development of novel pharmacological treatments that address the specific biological pathways involved.

- He has submitted a grant application to pursue those missing genes and is working on another proposal for funding to continue that pursuit using the large database of patient samples.
- Once the team recognized an eye color connection, they reanalyzed their data three times, comparing the participants’ age, gender and differences in backgrounds and locations.
- Treatments can include medication and counseling, and it may be possible for you to moderate your drinking rather than quit altogether.
Too much alcohol affects your speech, muscle coordination and vital centers of your brain. This is of particular concern when you’re taking certain medications that also depress https://rehabliving.net/barbiturates-definition-types-uses-side-effects/ the brain’s function. Dr. Li wants to delve deeper into the relationship between cultural background and genetic makeup to find the mechanisms of mental illness.
Some people have eyes with different colors, spots, and specks mixed in with their primary eye color. Ultimately, prevention strategies that integrate genetic insights must also consider environmental factors and personal experiences to be truly effective. Multifaceted approaches that combine genetic screening with education, early intervention, and support systems are likely to be the most successful in preventing alcoholism and its related consequences. Research into these mechanisms may eventually contribute to the development of more targeted treatment and prevention strategies, considering the multifaceted nature of genetic and environmental influences on health. But if they can confirm the link, the big challenge will be working out whether it’s caused by genetics, environmental factors, or a mix of the two. Many people with alcohol use disorder hesitate to get treatment because they don’t recognize that they have a problem.
However, she said if they also have a family history, they can meet with a genetic counselor to talk about risks of developing alcoholism. That is to say, when someone struggles with mental health symptoms, it is not unlikely that they will also struggle with substance abuse or addiction. In fact, it may be an even more prominent indicator of an increased risk of an alcohol use disorder than eye color. New research suggests the risks of even moderate or light drinking may outweigh the benefits. In June, the World Health Organization said that no level of alcohol consumption is safe for our health. And a new study funded by the National Institutes of Health found that binge drinking among adults ages 35 to 50 has reached historic levels.
