Addiction as a Brain Disease - Addiction Test
Although changes in the brain surely don't cause us to begin experimenting with alcohol or drugs, by the time we become addicted, changes in brain chemistry can make it very tough to quit using.
Addiction and Changes to the Brain? The chronic use of drugs and alcohol can lead to lasting, or even permanent changes in brain structure and function. These brain changes tend to reinforce drug seeking behaviors and make it harder for people to resist temptation.
- In some cases, changes in the brain result in a diminished ability to experience pleasure without intoxication (diminished dopamine response). People who cannot experience normal pleasure without using drugs have an understandably hard time quitting their use. Drugs that can cause this response include heroin and other opiates, methamphetamine, cocaine and alcohol
- Changes in brain chemistry can result in temporarily or permanently diminished memory and cognitive function. Changes to activity in the prefrontal cortex alters our ability to make good decisions and to stick to long term plans, and this contributes to the perpetuation of addiction1
