Introduction

  • Speaker: Dr. Russell Barkley, Clinical Professor of Psychiatry
  • Topic: Nature, impairments, causes, and treatments of adult ADHD
  • Adult ADHD recognized in medical literature for over 240 years

Historical Background

  • Early References:
    • Milkier Adam Weikert and Alexander Crichton documented attention disorders in adults
  • 1960s-70s: Follow-up studies of hyperactive children into adulthood
  • 1990s: Wider public recognition due to publications like "Driven to Distraction"

Diagnosis of ADHD

  • Manual Used: Diagnostic and Statistical Manual for Mental Disorders (DSM-5)
  • Criteria:
    • Inattention symptoms (5 or more needed)
    • Hyperactive/impulsive symptoms (5 or more needed)
    • Symptoms must be inappropriate for age
    • Must occur in multiple settings and cause impairment
    • Onset typically in childhood or adolescence
  • Challenges: Symptoms are more applicable to children than adults

Understanding Symptoms

  • Inattention: Problems with sustained attention and goal persistence
  • Impulsivity: Involves motor, verbal, cognitive, motivational, and emotional impulsiveness
  • Executive Functions: Majorly impaired in ADHD; includes self-control, working memory, emotional self-regulation, and planning

Impacts and Comorbidities

  • Life Impacts: Education, relationships, legal issues, substance abuse, health risks
  • Comorbid Disorders: Oppositional disorder, conduct disorder, anxiety, depression, learning disabilities, etc.

Causes of ADHD

  • Genetic Influence: 70-80% influenced genetically
  • New Mutations (De Novo): Accumulation of mutations in older parents' gametes
  • Other Factors: Premature birth, prenatal alcohol exposure, environmental toxins, infections

Evaluation and Diagnosis

  • Process:
    • Open-ended interview about concerns
    • Review DSM-5 criteria
    • Use behavior rating scales for deviance
    • Corroborate self-reports with other sources
    • Rule out malingering, especially in contexts like universities

Treatment and Management

  • Five Components:
    1. Evaluation
    2. Education
    3. Medication (Stimulants, Non-Stimulants, Alpha-2 Agonists)
    4. Behavior Modification (CBT, mindfulness)
    5. Environmental Accommodations
  • Medication: Most effective treatment; includes stimulants like methylphenidate, amphetamines
  • Lifestyle Adjustments: Exercise, dietary changes, environmental modifications
  • Job Considerations: Roles allowing more movement, hands-on work, flexibility, creativity

Conclusion

  • Adult ADHD is a disorder of self-regulation and executive function
  • It is common, affecting 3-5% of adults in the U.S.
  • Highly treatable with potential for meaningful lives with proper management
  • Emphasis on early diagnosis and comprehensive treatment approach

Note: These notes summarize the key points from Dr. Barkley's lecture on adult ADHD, and provide a high-level overview of the condition, its recognition, diagnosis, causes, impacts, and treatment strategies.
