Addictions

Overview of Addiction

• Definition Complexity

  • Different definitions exist; addiction is a term with varied meanings based on context.

  • Core components of addiction:

  1. Engagement: The activity or substance is something one enjoys doing.

  2. Compulsion: An inability to stop the behavior despite wanting to.

  3. Consequences: The behavior or substance use leads to negative outcomes in life.

• Brain Disease Theory:

  • Proposes that habitual use of substances or compulsive behaviors leads to changes in brain function and structure.

  • Emphasizes the alterations in neural circuitry related to addiction.

Behavioral Addiction

• Inclusion in DSM:

  • Behavioral addictions, such as gambling, were first recognized in DSM-5.

  • Importance of understanding neural pathways in both substance and behavioral addictions.

Neurological Mechanisms

• Dopamine and Reward Pathways:

  • Pleasure derived from activities/substances is linked to increased dopamine in the nucleus accumbens.

  • Common neural circuitry is shared across both substance and behavioral addictions.

Diagnostic Criteria for Substance Use Disorders

• Types of Use Disorders:

  • Various specific substance use disorders exist (e.g., opioid use disorder, alcohol use disorder).

  • Diagnostic criteria derived from DSM focus on impaired control among first four criteria.

• Lifetime Prevalence:

  • Refers to the likelihood of an individual meeting diagnostic criteria for an addiction at some point.

Co-occurring Mental Health Disorders

• Dual Diagnosis Concept:

  • High rates of co-occurrence between substance use disorder and mental health conditions, often referred to as dual diagnosis.

  • Statistics: Only about 10% of individuals receive treatment for both conditions; about 35% are treated solely for mental health conditions.

• Self-Medication Hypothesis:

  • Common belief: people use substances to alleviate mental health symptoms.

  • Evidence suggests this is not accurate, as data indicates:

  • People with depression do not necessarily choose substances that help them feel better.

  • Withdrawal and symptoms often persist regardless of mental health fluctuations.

Genetic and Environmental Factors

• Genetic Vulnerabilities:

  • Genetic predispositions can influence the likelihood of developing mental health issues post-substance use.

  • Substance use can trigger genetic predispositions, exacerbating mental health symptoms.

• Common Neurocognitive Issues:

  • Problems with self-regulation noted in both substance use disorders and certain mental health conditions.

  • Early exposure to adverse life experiences may influence susceptibility to both issues as one develops.

Treatment Paradigms

• Historical Treatment Approaches:

  • Traditionally, substance use disorders are treated first, with the hope of addressing remaining mental health symptoms afterward.

  • Current paradigms advocate treating both issues simultaneously to manage overall functioning and impairment.

• Integrated Treatment:

  • Combined approaches to address substance use and mental health concurrently.

  • Significance in addressing depressive symptoms alongside substance withdrawal during detox.

Medications for Substance Use Disorders

• Common Medications:

  • Disulfiram (Antabuse): causes nausea/vomiting when combined with alcohol.

  • Naltrexone: helps curb cravings; also used for binge eating disorders, blocking euphoric effects from opioids.

  • Wellbutrin (Bupropion): a dopamine and norepinephrine reuptake inhibitor (DNRI) used for smoking cessation and also binge eating.

• Benzodiazepines:

  • Used to manage withdrawal symptoms from alcohol, given their chemical similarities to alcohol.

  • Tapering process typically begins with a higher dose and gradually reduces over time.

• CAPRO (Gabapentinoids):

  • Regulates glutamate to alleviate withdrawal; may be effective in reducing negative withdrawal symptoms when combined with naltrexone.

Opioid Use Disorder

• Overview of Opioids:

  • Opioids, both naturally occurring and synthetic, bind to opioid receptors and modulate pain, euphoria, and sedation.

• Withdrawal Management:

  • Naloxone: rapid opioid receptor blocker to use in cases of overdose.

  • Methadone: a synthetic opioid used for maintenance treatments that helps manage withdrawal symptoms without euphoric effects.

Implications of Treatment Approaches

• Treatment Challenges:

  • Recovery often involves the challenge of balancing treatment logistics (e.g., strict clinic hours for methadone therapy) and personal life.

  • Tough reality of relapse upon discontinuation of maintenance treatments like methadone, with high rates of return to substance use.

• Ethical Considerations:

  • Debate exists over the treatment of clients solely for substance use before addressing their underlying mental health conditions.

  • Importance of recognizing and treating co-occurring conditions effectively to promote overall recovery.
