Yes, addiction is considered a brain disorder. This is because addiction affects the way the brain functions and how it interacts with the body. In particular, addiction alters the way that certain neurotransmitters, such as dopamine, are released and received by the brain. This can lead to changes in behavior and an inability to control impulses or cravings.
Addiction is also classified as a chronic brain disease because of the way it can alter brain chemistry. When someone has an addiction, their brain chemistry changes as a result of the substance being taken and the behaviors associated with the addiction. This can result in an inability to control certain impulses or cravings, as well as changes in behavior and mood.
In addition, addiction can lead to changes in the structure of the brain. This can include alterations in certain areas of the brain, such as the prefrontal cortex, which is responsible for decision-making and impulse control. It can also lead to changes in the hippocampus, which is responsible for memory formation and learning.
Overall, addiction is classified as a brain disorder because it alters the way the brain functions and interacts with the body. It can also lead to changes in brain chemistry, structure, and behavior.
