Psychopathy (Antisocial Personality Disorder)

Key Points

  • Diagnostic Tools: DSM-5 & Psychopathy Checklist Revised (PCL-R)
    • Developed by Robert Hare
    • 20-item scale; scores range from 0 (not at all) to 2 (definitely)
    • Standard cutoff: 30 out of 40 indicates psychopathy

Symptoms

  • Pathological lying
  • Absence of guilt
  • Early behavior issues (conduct disorder in children)
  • Grandiose sense of self-worth

Prevalence and Examples

  • About 1% of the population
  • Often successful in business or politics

Causes

  • Genetic Component: MAOA gene linked to psychopathy
  • Gene-Environment Interaction: High risk if both gene and childhood trauma/abuse are present

Neurological Basis

  • Involvement of prefrontal cortex and amygdala
  • Reduced activity in amygdala, affecting fear responses

Evolutionary Perspective

  • Frequency-dependent selection keeps psychopathic traits rare
  • Psychopaths as "cheaters" in altruistic systems
  • Significant sex differences; predominantly men

Borderline Personality Disorder (BPD)

Key Points

  • Symptoms: Emotional instability, hostility, impulsivity
  • Behavior: Extreme mood swings, manipulative actions

Causal Factors

  • Splitting: Inability to integrate good and bad traits of individuals
  • Sex Differences: More prevalent in women

Developmental Disorders

ADHD (Attention Deficit Hyperactivity Disorder)

  • Subtypes: Previously divided into Autism and Asperger’s
  • Intellectual Range: Varies from intellectual disability to above-average intelligence
  • Savant Syndrome: Extreme ability in one area

Causes

  • Heritability: High genetic influence, impairments in theory of mind
  • Vaccination Myth: Disproved claim linking vaccines to autism

Dementia

Alzheimer's Disease

  • Symptoms: Cognitive decline, memory loss
  • Diagnosis: Presence of amyloid plaques and neurofibrillary tangles
  • Impact: Significant brain atrophy, especially in the hippocampus
