How do biological factors influence a person’s risk of alcoholism?

For some, alcohol gives off feelings of pleasure, encouraging the brain to repeat the behavior. Repetitive behavior like this can make you more vulnerable to developing alcoholism. There are also certain chemicals in the brain that can make you more susceptible to alcohol abuse.

What are the biological factors of alcohol?

Alcoholism causes changes to the brain in at least four fundamental ways:

  • Alcoholism causes changes to the brain’s natural balance (homeostasis).
  • Alcoholism alters brain chemistry.
  • Alcoholism changes the brain’s communication patterns.
  • Alcoholism causes changes to brain structures and their functioning.

What are some biological and psychosocial factors that contribute to the development of alcoholism?

Researchers hypothesize, for example, that in childhood, biologically based vulnerabilities in emotional and behavioral regulation (tempera- ment or personality) interact with poor parenting to create emotional distress and exposure to nega- tive peer influences, both of which create risk for alcohol misuse.

Do genetic factors play a role 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.

Environmental influences on alcohol use include: acceptance of alcohol use by society; availability (including price, number of outlets, and server practices); advertising and marketing both nationally and locally; and public policies regarding alcohol and enforcement of those policies.

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).

How does genetics play a role in addiction?

Genes influence the numbers and types of receptors in peoples’ brains, how quickly their bodies metabolize drugs, and how well they respond to different medications. Learning more about the genetic, epigenetic, and neurobiological bases of addiction will eventually advance the science of addiction.

What is the difference between hereditary and genetic?

The main difference between these two terms lies in the fact that hereditary diseases have the potential of being carried from one generation to another whereas a genetic disease can either be hereditary or not, but there will always be a mutational change in the genome.
