What is the evidence for and against Genetics in Alcoholism?

Abundant evidence indicates that alcoholism is a complex genetic disease, with variations in a large number of genes affecting risk. Some of these genes have been identified, including two genes of alcohol metabolism, ADH1B and ALDH2, that have the strongest known affects on risk for alcoholism.

Why do researchers analyze biological genetic and environmental factors when determining the likelihood of developing alcoholism?

Research shows that genes are responsible for about half of the risk for AUD. Therefore, genes alone do not determine whether someone will develop AUD. Environmental factors, as well as gene and environment interactions account for the remainder of the risk.

What are some signs that a person may be a problem drinker?

As the effects of alcohol wear off, you may have trouble sleeping, shakiness, irritability, anxiety, depression, restlessness, nausea, or sweating. Alcohol changes your brain chemistry, and when you drink heavily over a long period of time, your brain tries to adapt.

What is the heritability of alcoholism?

The heritability of alcohol dependence is estimated to range between 40 and 65%, with no evidence for quantitative or qualitative sex differences in heritability (Kendler et al., 1994; Heath et al., 1997; Prescott and Kendler, 1999; Hansell et al., 2008).

Which mental disorder is most commonly comorbid with alcoholism?

According to the National Institutes of Health (NIH), three mental disorders most commonly comorbid with alcoholism are major depression, bipolar disorder and anxiety disorder. Less frequently co-diagnosed with alcoholism is post-traumatic stress disorder (PTSD), dependent personality disorder and conduct disorder.

How do genetics play a role in alcoholism?

Statistically, a family history of alcoholism is linked to an increased risk of genetic predisposition to alcoholism, depending on how close the relatives are to each other. Children who have one parent who struggles with alcohol use disorder have a 3-4 times increased risk of becoming an alcoholic themselves.
