Study Notes
Addiction Mechanisms
Reward System
- The brain's reward system is responsible for motivation and pleasure
- Activation of the reward system releases feel-good chemicals like dopamine
- Drugs and alcohol can hijack the reward system, leading to addiction
Dopamine Release
- Dopamine is released in response to pleasurable activities, including drug use
- Repeated drug use can lead to long-term changes in dopamine release and reception
- This can result in tolerance, where more of the substance is needed to achieve the same high
Tolerance and Withdrawal
- Tolerance: the need for increased amounts of a substance to achieve the same effect
- Withdrawal: the occurrence of unpleasant symptoms when substance use is stopped or reduced
- Both tolerance and withdrawal can drive continued substance use, despite negative consequences
Long-term Brain Changes
- Repeated exposure to drugs and alcohol can lead to changes in brain structure and function
- These changes can affect areas responsible for motivation, emotion regulation, and decision-making
- Long-term changes can contribute to the development of addiction
Neuroadaptation
- Neuroadaptation: the brain's ability to adapt to the presence of a substance
- Repeated exposure to a substance can lead to neuroadaptation, making it difficult to stop using
- Neuroadaptation can contribute to the development of addiction and relapse
Stress and Addiction
- Stress can activate the brain's reward system, increasing the risk of addiction
- Chronic stress can lead to long-term changes in the brain, making it more susceptible to addiction
- Managing stress is an important aspect of addiction treatment and recovery
Addiction Mechanisms
Reward System
- The brain's reward system is responsible for motivation and pleasure, and its activation releases feel-good chemicals like dopamine.
- Drugs and alcohol can hijack the reward system, leading to addiction.
Dopamine Release
- Dopamine is released in response to pleasurable activities, including drug use, and repeated use can lead to long-term changes in dopamine release and reception.
- Long-term changes in dopamine release can result in tolerance, where more of the substance is needed to achieve the same high.
Tolerance and Withdrawal
- Tolerance occurs when the brain adapts to the constant presence of a substance, requiring increased amounts to achieve the same effect.
- Withdrawal occurs when substance use is stopped or reduced, leading to unpleasant symptoms.
- Both tolerance and withdrawal can drive continued substance use despite negative consequences.
Long-term Brain Changes
- Repeated exposure to drugs and alcohol can lead to changes in brain structure and function, affecting areas responsible for motivation, emotion regulation, and decision-making.
- Long-term changes can contribute to the development of addiction.
