Study Notes
Substance Abuse/Misuse
- Drug misuse can lead to health issues, including addiction, organ damage, and mental health complications.
- Drug use can affect job performance, attendance, and lead to job loss.
- Drug abuse can strain relationships with family, friends, and partners.
- Drug misuse involves taking drugs more frequently, in larger quantities, or for reasons other than their intended use.
Withdrawal
- Withdrawal occurs when drug use is stopped.
- Withdrawal symptoms vary depending on the drug and individual.
- People may use closely related substances to alleviate withdrawal symptoms.
Craving
- Craving is a powerful drive to use a substance.
- Cravings can be intense, but they are not insurmountable.
- It's possible to manage cravings and regain control.
- Seeking help from a healthcare professional can be beneficial.
Addiction and Reinforcement
- Addiction is reinforced by positive and negative reinforcement, creating a cycle of dependence.
- Cognitive distortions, such as denial and minimization, contribute to the maintenance of addiction.
- Cognitive restructuring can change negative thoughts and behaviors.
- Therapy, skills training, and coping mechanisms are helpful with cognitive restructuring.
Psychoanalytic Model of Addiction
- Early childhood experiences and trauma may contribute to addiction.
- Addiction can be a way to manage unconscious conflicts, relieve anxiety, or fill a void.
- Addiction might be a defense mechanism against painful emotions or challenging situations.
- Addiction could be a way to meet unmet needs or recreate problematic relationships from the past.
Social Learning Theory of Addiction
- Observational learning, by watching others engage in addictive behaviors, contributes to addiction.
- Modeling and reinforcement increase the likelihood of engaging in addictive behaviors.
- Social norms and cultural contexts influence the perception of addictive behaviors.
- Social support systems can either encourage or discourage addictive behaviors.
Ecological Model of Addiction
- This model considers multiple factors, including individual, family, community, and societal factors, that influence addiction.
- Social determinants like poverty, access healthcare, and social support networks play a role.
- The Ecological Model emphasizes addressing addiction through a systemic approach, involving multiple stakeholders.
Stages of Change Model
- The first stage is precontemplation, where individuals are unaware or unwilling to change.
- The model focuses on the individual's journey through stages of change to address addiction.
Hedonic Regulation Theory of Addiction
- This theory explains how individuals try to maintain a pleasurable state.
- Addiction disrupts the balance, leading to allostasis and disruption of homeostasis.
- Withdrawal creates a negative state, driving cravings for the substance.
The Role of Dopamine in Addiction
- Dopamine is a neurotransmitter in the brain's reward system.
- Dopamine release is heightened during drug use, reinforcing the connection between the substance and pleasure.
- Repeated drug use leads to changes in the dopamine system, including a decrease in dopamine receptors and altered signaling pathways.
- These changes contribute to tolerance, withdrawal, and persistent cravings.
Incentive Salience and Craving
- Incentive salience assigns motivational value to drug-related cues and stimuli.
- Craving is a strong desire for the drug, triggered by various factors, such as drug-related cues, stress, and social situations.
- The intensity of craving often increases over time since the last drug use.
Tolerance and Withdrawal in Addiction
- Tolerance refers to the decreasing effectiveness of a substance with repeated use.
- Withdrawal refers to the unpleasant physical and psychological symptoms that occur when someone stops using a substance.
- The cycle of tolerance and withdrawal can contribute to compulsive use and difficulty stopping drug use.
Allostatic Model of Addiction
- Chronic drug use leads to changes in the brain's stress response system, creating a state of dysregulation.
- This results in chronic stress, characterized by increased cortisol and cravings.
- The model highlights the interplay between the brain's reward system, stress response system, and the body's physiological responses to drug use.
Opponent-Process Theory of Addiction
- Repeated exposure to an addictive substance elicits both pleasurable and aversive responses.
- Withdrawal symptoms intensify with repeated use and drive continued drug-seeking behaviors.
- Over time the pleasure-seeking response weakens while the withdrawal response intensifies.
Conclusion and Future Directions
- Understanding addiction is essential for developing effective treatment strategies.
- Future research should focus on integrating different theories to understand addiction.
- Further investigation into the role of genetics, epigenetics, and environmental factors is needed.
- Personalized treatment approaches should address individual vulnerabilities and strengths.
The Brain Science of Addiction
- Addiction is a chronic disease of brain reward, motivation, memory, and related circuitry.
- It is a primary brain disease, not a weakness or lack willpower.
- Repeated drug use can lead to long-lasting health changes, including brain changes.
Dopamine and Substance Use
- Dopamine is a neurotransmitter involved in pleasure and reward.
- Dopamine is released during pleasurable experiences, reinforcing behaviors.
- Drug use increases dopamine release, leading to cravings and compulsive drug-seeking behaviors.
Dopamine Receptors in Addiction
- Repeated drug use depletes dopamine receptors in the brain.
- This makes it difficult for individuals to experience pleasure in healthy ways.
- These brain changes make it harder to stop using drugs.
Effects of Meth on the Brain
- Methamphetamine use causes significant changes in brain structure and function.
- There is hope for recovery with prolonged abstinence.
Brain Disease Model of Addiction
- Addiction is a chronic, relapsing brain disease.
- Brain changes associated with addiction can be reversed with treatment and abstinence.
- Recovery is possible, and individuals can regain control over their lives.
How Drugs Change Brain Function
- Drugs interfere with or alter the brain's neurotransmitters, which allow neurons to communicate.
- These changes can disrupt brain functions, behaviors, and experiences.
- Understanding the brain science of addiction provides insights into how drugs impact the brain and support the development of effective treatment strategies.
