    • Psychological Dimension

    • Sociological Dimension

    • Case Study Video

Course Structure Changes

  • Next Week's Focus: Chapter 14

    • Topics include:

    • Sexual Dysfunction

    • Gender Dysphoria

    • Pedophilia

Genetic and Biological Factors in Schizophrenia

  • Strong Biological Arguments:

    • A significant genetic component in the onset of schizophrenia

    • High heritability rates:

    • Closer kinship to an individual with schizophrenia increases likelihood of similar diagnosis

Psychological Dimension of Schizophrenia

  • Negative Symptoms:

    • Deficits in empathy:

    • Poor ability to understand others' perspectives

    • Focus on one's own thoughts and feelings

    • Self-centered mindset

  • Early Developmental Delays:

    • Association with later onset of schizophrenia

    • Cognitive deficits during childhood and adolescence may indicate future problems:

    • Lower cognitive scores linked to brain abnormalities

  • Negative Outlook on Life:

    • Tendency to misattribute blame and avoid responsibility

    • Poor outlook and inability to take credit where due

Sociological Factors Contributing to Schizophrenia

  • Dysfunctional Family Patterns:

    • Childhood maltreatment as a significant risk factor:

    • Severe physical or mental abuse in childhood

    • Chronic bullying

    • Historical context:

    • Early explanations focused on family dysfunction before genetic influences were understood

  • Expressed Emotion:

    • Negative communication patterns within families

    • Family blame and criticism exacerbate stress for the individual

Risk Ratios and Childhood Trauma

  • Risk ratio of developing schizophrenia linked to childhood trauma, including:

    • Bullying and maltreatment

    • At age 11, cumulative trauma increases risk by six times

Cultural Perspectives on Schizophrenia

  • Stigmatization of Schizophrenia Globally:

    • Highly stigmatized in various cultures

    • In some cultures, family is not informed about the diagnosis

    • Misunderstanding of causes: supernatural vs. biological explanations

  • Variance in Medical Explanations:

    • UK: Predominantly biological explanations

    • Caribbean: Social factors and dysfunctional family explanations dominate

Systemic Racism and Psychosis

  • Hypothesis linking institutionalized systems and development of psychosis

    • Structural racism influences neighborhood disadvantages and collective trauma

    • Stress alters neurobiology and may lead to psychosis

Treatment Options for Schizophrenia

  • Historical and Modern Treatments:

    • Lobotomies once common, performed in some regions still

    • Effective for positive symptoms but disconnects the patient from their personality

  • Current Treatments:

    • Medication (e.g., Thorazine, Abilify)

    • Cognitive Behavioral Therapy (CBT)

    • Recovery model emphasizes the possibility of leading a fulfilling life despite the disorder

  • Medications Details:

    • Thorazine introduced in 1955, reduces positive symptoms

    • Side effects can stifle creativity and overall motivation

    • Works for about two-thirds; one-third shows no reaction

    • Abilify mentioned as an effective antipsychotic medication

Side Effects of Medications

  • Common side effects include:

    • Weight gain

    • Sedation

    • Parkinsonian-like symptoms

    • Tardive dyskinesia: involuntary repetitive mouth movements

Social and Group Therapy Approaches

  • Emphasis on social cognition and therapeutic group settings

    • Challenges discussed among peers to improve coping strategies

  • Importance of positive family interactions in treatment

    • Family therapy educating family members about the disorder

Case Study Video Analysis

  • Features a real individual (Andre) discussing his experiences:

    • Recognition of psychotic episodes starting at age 15

    • Claims of having children and worries about familial relationships

    • Expresses thoughts on his medication improving clarity

  • Observations of his conduct:

    • Indicates signs of functional difficulty and cognitive impairment

    • Relationship dynamics with peers affected by mutual accusatory behavior

Concluding Thoughts

  • Insights into the comprehensive and multifaceted understanding of schizophrenia, emphasizing the interplay between genetic predispositions, psychological factors, sociological influences, and treatment methodologies.
