Intro to Psychology Unit 15 Review: Psychological Disorders

What Are Psychological Disorders?

• Psychological disorders involve significant disturbances in thoughts, emotions, and behaviors that cause distress or impair functioning
• Deviate from cultural norms and interfere with a person's ability to function effectively in daily life (work, relationships, self-care)
• Characterized by specific symptoms that are persistent and severe enough to meet diagnostic criteria
• Can affect people of all ages, genders, and backgrounds
• Often co-occur with other mental health conditions (anxiety disorders, substance use disorders)
• Severity exists on a continuum from mild to severe impairment
• Differ from temporary stress reactions or eccentricities in behavior
  • Stress reactions are typically short-lived and resolve with time or support
  • Eccentricities do not cause significant distress or impairment

Types of Psychological Disorders

• Anxiety Disorders
  • Characterized by excessive fear, worry, and avoidance behaviors (phobias, panic disorder, generalized anxiety disorder)
• Mood Disorders
  • Involve persistent disturbances in emotional states (major depressive disorder, bipolar disorder)
• Personality Disorders
  • Enduring patterns of inner experience and behavior that deviate markedly from cultural norms (borderline personality disorder, narcissistic personality disorder)
• Psychotic Disorders
  • Characterized by a disconnection from reality, including delusions and hallucinations (schizophrenia)
• Eating Disorders
  • Involve severe disturbances in eating behaviors and body image (anorexia nervosa, bulimia nervosa)
• Trauma and Stressor-Related Disorders
  • Develop in response to traumatic or stressful events (post-traumatic stress disorder, acute stress disorder)
• Neurodevelopmental Disorders
  • Arise during the developmental period and affect brain functioning (autism spectrum disorder, attention-deficit/hyperactivity disorder)
• Substance-Related and Addictive Disorders
  • Involve problematic use of substances or addictive behaviors (alcohol use disorder, gambling disorder)

Causes and Risk Factors

• Biological factors
  • Genetic predispositions increase vulnerability to certain disorders
  • Neurotransmitter imbalances (serotonin, dopamine) contribute to mood and anxiety disorders
  • Brain structure and function abnormalities are associated with various disorders
• Psychological factors
  • Early life experiences (trauma, neglect) can shape emotional development and coping mechanisms
  • Cognitive distortions and negative thought patterns perpetuate mental health issues
  • Personality traits (neuroticism, impulsivity) increase risk for certain disorders
• Social and environmental factors
  • Stressful life events (loss, relationship problems) can trigger or exacerbate symptoms
  • Lack of social support and isolation contribute to the development and maintenance of disorders
  • Cultural and societal norms influence the expression and perception of mental health
• Biopsychosocial model
  • Recognizes the complex interplay of biological, psychological, and social factors in the development of psychological disorders
  • Emphasizes a holistic approach to understanding and treating mental health conditions

Diagnosis and Assessment

• Diagnostic and Statistical Manual of Mental Disorders (DSM-5)
  • Provides standardized criteria for diagnosing psychological disorders
  • Categorizes disorders based on symptoms, duration, and severity
• Clinical interviews
  • Mental health professionals gather information about symptoms, history, and functioning through structured or unstructured interviews
• Psychological assessments
  • Self-report questionnaires (Beck Depression Inventory) assess specific symptoms and severity
  • Neuropsychological tests evaluate cognitive functioning and brain-behavior relationships
• Medical evaluations
  • Rule out underlying medical conditions that may contribute to psychological symptoms
  • Assess physical health and potential side effects of medications
• Differential diagnosis
  • Considers multiple possible diagnoses based on presenting symptoms
  • Distinguishes between disorders with similar or overlapping features
• Collaborative approach
  • Involves the individual, family members, and other healthcare providers in the diagnostic process
  • Considers cultural and contextual factors that may influence the presentation of symptoms

Treatment Approaches

• Psychotherapy
  • Cognitive-behavioral therapy (CBT) focuses on modifying negative thoughts and behaviors
  • Interpersonal therapy (IPT) addresses relationship issues and interpersonal conflicts
  • Dialectical behavior therapy (DBT) teaches emotion regulation and distress tolerance skills
• Medication
  • Antidepressants (SSRIs, SNRIs) treat mood and anxiety disorders by regulating neurotransmitter levels
  • Antipsychotics manage symptoms of psychotic disorders by reducing dopamine activity
  • Mood stabilizers (lithium) help regulate mood swings in bipolar disorder
• Combination of psychotherapy and medication
  • Often the most effective approach for many psychological disorders
  • Addresses both the psychological and biological aspects of the condition
• Lifestyle changes
  • Regular exercise, healthy diet, and adequate sleep promote mental well-being
  • Stress management techniques (relaxation, mindfulness) reduce symptoms of anxiety and depression
• Social support
  • Engaging in supportive relationships and community activities fosters resilience
  • Peer support groups provide a sense of belonging and shared experiences

Living with Psychological Disorders

• Coping strategies
  • Developing healthy coping mechanisms (journaling, art therapy) to manage symptoms
  • Identifying and avoiding triggers that exacerbate symptoms
• Self-care
  • Prioritizing physical health through regular check-ups and preventive care
  • Engaging in activities that promote relaxation and enjoyment
• Stigma and discrimination
  • Facing societal stigma and misconceptions about mental illness
  • Advocating for oneself and educating others to reduce stigma
• Occupational challenges
  • Managing symptoms in the workplace and seeking accommodations when needed
  • Balancing work demands with self-care and treatment
• Relationship dynamics
  • Communicating openly with loved ones about the impact of the disorder on relationships
  • Setting healthy boundaries and seeking support from friends and family
• Recovery and resilience
  • Recognizing that recovery is a journey with ups and downs
  • Celebrating small victories and building resilience in the face of challenges

Stigma and Mental Health Awareness

• Misconceptions and stereotypes
  • Challenging common myths and stereotypes about mental illness (dangerousness, weakness)
  • Promoting accurate information and understanding of psychological disorders
• Media portrayal
  • Examining how media representations shape public perceptions of mental health
  • Advocating for responsible and accurate portrayals in news, entertainment, and social media
• Language and terminology
  • Using person-first language (person with schizophrenia vs. schizophrenic)
  • Avoiding stigmatizing or dismissive terms (crazy, psycho)
• Education and awareness campaigns
  • Promoting mental health literacy through public education initiatives
  • Encouraging open conversations about mental health in schools, workplaces, and communities
• Access to care
  • Addressing barriers to seeking and receiving mental health services (cost, availability)
  • Advocating for policies that improve access to quality care for all individuals
• Intersectionality
  • Recognizing the unique challenges faced by marginalized communities in accessing mental health support
  • Addressing the intersection of mental health with race, ethnicity, gender, and socioeconomic status

Current Research and Future Directions

• Neuroscience and brain imaging
  • Investigating the neural basis of psychological disorders using advanced imaging techniques (fMRI, PET scans)
  • Identifying biomarkers and potential targets for treatment
• Genetics and epigenetics
  • Exploring the role of genetic variations in the development of psychological disorders
