Problem: The biological theory depicts that past generations of family members who have struggled with addiction can represent a precursor to the current generation of abused family members. Examples of biological models include genetic models and neurobiological models (Capuzzi & Stauffer, 2020). The biological model uses medical terminology to explain the process. This means medical professionals like doctors or psychiatrists contribute to genetics. This allows professionals to make sure that addicted people are taken care of properly. The genetic model uses empirical research and genetic reasons to explain the cause of addiction and alcoholism disorder. The difference is genetic, like family history, and the number of chromosomes you have can contribute to the addictive behavior. Capuzzi Stauffer found in a study that alcoholism or the use of drugs can contribute to various families. Children with alcoholic parents are at an increased risk of becoming addicted to alcohol than children who do not have alcoholic parents (Capuzzi & Stauffer, 2020). The neurobiological models show that neurotransmitters are a messenger system. Neurotransmitters can be affected by addicted people who are suffering from drug addiction or alcoholism (Blum et al., 2020). When you are addicted to drugs or alcohol, it can send messages to the limbic part of the brain, which can release things like serotonin, epinephrine, or dopamine. These chemicals bring pleasure and positively increase the person's mood. An increased use of drugs contributes to dependency and can overall make changes to the limbic system. Need Assignment Help?
