Integrating amyloid imaging and genetics for early risk stratification of Alzheimer’s disease

The genetic connection to addiction comes through inherited levels of dopamine, a neurotransmitter made in your brain. But does that mean your chance of addiction is alcoholism a hereditary disease is essentially a coin flip if you have a family history of SUD? It’s a little more complicated than that, says addiction psychiatrist Akhil Anand, MD.

The alcohol flushing response is associated with the risk of depression

In the future, there may be genetic therapies that help people control how much alcohol they consume; for now, behavioral therapies have proven very effective at managing these chronic health conditions. For example, it has already provided a test of new methods for genetic analysis, as presented at the Genetic Analysis Workshop 11 (Begleiter et al. 1999). In addition, COGA researchers are currently re-interviewing https://ecosoberhouse.com/ participants as part of a 5-year followup. This strategy will allow the investigators to increase the reliability of the data and to refine the phenotypes, which in turn will enhance the power of the genetic analyses. As the field of genomics is rapidly expanding, with advances in technology and decreases in costs, whole genome sequencing is expected to become feasible in the near future.

Genetical Sensitivities to Alcohol

Recognizing alcoholism as a disease promotes early intervention, access to appropriate healthcare services, and ongoing support for people struggling with AUD. It’s a chronic condition characterized by excessive and compulsive consumption of alcohol, despite harmful consequences. “These genes are for risk, not for destiny,” stressed Dr. Enoch Gordis, director of the National Institute on Alcohol Abuse and Alcoholism. He added that the research could help in identifying youngsters at risk of becoming alcoholics and could lead to early prevention efforts.

• Therefore, COGA researchers gathered a detailed psychiatric history of each participant, along with electrophysiological data (electroencephalograms [EEGs] and event-related potentials [ERPs]).

• The risk of several other kidney disorders is moderately raised, though the variants don’t seem to affect the risk for diabetes-related kidney disease.
• Study findings confirmed the observational relationship between the factors but failed to provide genetic causality for the same.
• There are 35 different ways one could pick 3 criteria from 7 (DSM-IValcohol dependence) and 330 ways to pick 4 from 11 (DSM-5 severe AUD).
• Severity is based on the number of criteria a person meets based on their symptoms—mild (2–3 criteria), moderate (4–5 criteria), or severe (6 or more criteria).
• Moreover, it will be equally important to determine the potential underlying mechanisms through functional studies, including the use of animal models, particularly those in which candidate genes or alleles are introduced into the organism (i.e., knocked-in).

Data collection, analysis, and/or storage for this study take place at nine sites across the United States. Because alcoholism is a complex genetic disorder, the COGA researchers expected that multiple genes would contribute to the risk. In other words, there will be no single “gene for alcoholism” but rather variations in many different genes that together, interacting with the environment, place some people at significantly higher risk for the disease. This genetic and environmental variability (i.e., heterogeneity) makes the task of identifying individual genes difficult. However, the COGA project was designed with these difficulties in mind and incorporated strategies to meet the challenges. This article briefly reviews these strategies and summarizes some of the results already obtained in the ongoing COGA study.

• It’s a little more complicated than that, says addiction psychiatrist Akhil Anand, MD.
• Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems.

Thinking of addiction as genetic begins with understanding that addiction is a chronic relapsing brain disorder. “In many ways, it’s no different than having a family history with heart disease or diabetes,” says Dr. Anand. Research shows that genetic and environmental factors play a role in its development.

The DSM-5 [1] currently requires the endorsement of any 2 of 11 criteria to reach the diagnostic threshold for AUD at the mild severity level. A study in Sweden followed alcohol use in twins who were adopted as children and reared apart. The incidence of alcoholism was slightly higher among people who were exposed to alcoholism only through their adoptive families.

It results most commonly from diabetes or hypertension, but sometimes from infectious diseases like HIV, or from lupus, an autoimmune disease. Occasionally, it occurs in isolation, such as in a disease called focal segmental glomerulosclerosis. FSGS often strikes children or younger adults, causing kidneys to degenerate with no other disease signs. The volunteers in 2023’s small inaxaplin trial all had FSGS, and it has been central to uncovering APOL1’s importance. Moxey-Mims and her colleagues now hope to use APOL1 screening to transform policies around kidney transplantation. And with Vertex currently testing inaxaplin in a large, placebo-controlled trial, hopes are high that medical options will soon expand for the tens of millions of people globally whose APOL1 genes put them at risk of kidney failure.

A short animated video from Vertex Pharmaceuticals explains the company’s approach to studying and treating APOL1-mediated kidney disease. But the reason they were recruited was because of which versions they had of the gene carrying instructions for making APOL1. Thirteen people with serious kidney disease given a new type of drug for three months had, on average, seen the amount of protein pathologically leaking into their urine fall by almost 50 percent. In this elemental test of kidney function, some participants saw an improvement of more than 70 percent.

The GI tract is exposed to very high levels of alcohol as it passes throughthe mouth, esophagus, stomach and intestinal tract, and most ethanol passes throughthe liver before entering the circulation. Alcohol levels in common drinks rangefrom approximately 5% (1.1 M) for beer, 11-15% for wine (∼3M) and 40% for spirits (∼9 M). The oral cavity and esophagus aredirectly exposed to those levels, and the liver is exposed to high levels from theportal circulation. Thus it is not surprising that diseases of the GI system,including cirrhosis, pancreatitis, and cancers of the upper GI tract are affected byalcohol consumption80-86. In the context of AUD, GCTA could be applied to the subsets of previously discussed SNPs that reached genome-wide significance and were correlated with alcohol-dependent phenotypes. GCTA estimates could be used for diagnostic purposes and provide further insight as to whether variants in ADH and ALDH, among other genes, in fact contribute to the genetic predisposition for AUD.
