Behavioral Addictions

Behavioral Addictions - Defining the Drive

• Definition: Compulsion for rewarding non-substance acts despite harm; loss of control.
• Types: Gambling, gaming, internet, shopping, sex, exercise.
• Common Features (📌 SALience To WiRe CoRe):
  • Salience: Behavior dominates life.
  • Mood modification: Behavior alters mood.
  • Tolerance: ↑ behavior for same effect.
  • Withdrawal: Negative effects on cessation.
  • Conflict: With self, others, activities.
  • Relapse: Return to behavior after stopping.
• Neurobiology:
  • Reward pathways (mesolimbic dopamine).
  • Overlaps substance addiction neurobiology (DA, Glu, 5-HT).

⭐ The neurobiological underpinnings of behavioral addictions show significant overlap with substance use disorders, particularly involving the brain's reward circuitry.

Gambling & Gaming - Digital Dopamine

• Gambling Disorder (GD)
  • DSM-5: ≥4 criteria in a 12-month period (e.g., preoccupation, chasing losses, jeopardized relationships/job/education, relies on others for money).
  • Phases: Winning → Losing → Desperation → Hopelessness.
  • Associated: Financial problems, comorbid mood/anxiety/substance use disorders, suicidal ideation.
• Internet Gaming Disorder (IGD)
  • DSM-5 (Section III - for further study): ≥5 criteria in 12 months (e.g., preoccupation with gaming, withdrawal symptoms, tolerance, loss of control, continued use despite psychosocial problems).
  • Impact: Significant psychosocial impairment (e.g., academic, occupational, social).

⭐ Gambling Disorder is the only behavioral addiction currently included in the main body of the DSM-5 under 'Substance-Related and Addictive Disorders' (as of DSM-5-TR).

Other Compulsions - Beyond the Screen

⭐ While not formally in DSM-5 as distinct disorders (except Gambling), these behaviors share core addiction features like preoccupation and loss of control.

Diagnosis & Assessment - Spotting the Signs

• Clinical Interview: Key for history, assessing behavior pattern, consequences, motivation to change.

  ⭐ Collateral information from family members is often crucial in assessing the extent and impact of behavioral addictions.

• Screening Tools:
  • Gambling: South Oaks Gambling Screen (SOGS) (score > 5 indicates probable pathological gambling), Lie/Bet Questionnaire.
  • Internet: Internet Addiction Test (IAT) by Young.
• Diagnostic Criteria:
  • Gambling Disorder: Utilize DSM-5 criteria.
  • Others: Focus on general addiction criteria (loss of control, functional impairment, significant distress).
• Differential Diagnosis: Crucial to rule out other psychiatric conditions (e.g., mania, OCD).

Treatment Approaches - Reclaiming Control

• Psychosocial Interventions (First-line):
  • Cognitive Behavioral Therapy (CBT): Identify triggers, cognitive restructuring, coping skills.
  • Motivational Interviewing (MI).
  • 12-Step Programs (e.g., Gamblers Anonymous).
• Pharmacological Approaches (Adjunctive/Off-label):
  • Naltrexone for Gambling Disorder: 50-100 mg/day.
  • SSRIs for comorbidities (e.g., depression, anxiety).
• Relapse Prevention & Support:
  • Strategies: Identify high-risk situations.
  • Family therapy/support crucial.

⭐ Cognitive Behavioral Therapy (CBT) is the most evidence-based psychosocial treatment for behavioral addictions, particularly Gambling Disorder.

High‑Yield Points - ⚡ Biggest Takeaways

• Behavioral addictions mirror substance use disorders with features like impaired control, craving, and continued use despite harm.
• Gambling Disorder is the only formal DSM-5 diagnosis in this class; Internet Gaming Disorder is a condition for further study.
• Mesolimbic dopamine pathway dysregulation is a crucial neurobiological mechanism, similar to substance dependence.
• Core features include impulsivity, compulsivity, and preoccupation with the behavior.
• Cognitive Behavioral Therapy (CBT) is the most established psychosocial treatment approach.
• Significant comorbidity exists with mood disorders, anxiety disorders, and ADHD.
