Week 4 (Tuesday) - Anxiety Disorders and Treatments

Exam Format and Recording

  • The Monday evening session will be recorded for those unable to attend, ensuring that all students have access to the information presented.

  • Questions must be submitted via Google Forms by Friday before the review session to allow adequate time for preparation and organization of responses.

  • The focus during the review will specifically be on the questions submitted by students, rather than providing a comprehensive overview of all topics covered in the course. This targeted approach allows for a more in-depth discussion of areas where students feel the need for clarification or further understanding.

Study Guides

  • No official study guide will be provided by the instructor.

  • Students are encouraged to create their own review sheets based on main topics from the slides presented during the lectures. This self-generated study material can enhance comprehension by actively engaging with the content.

  • It is important for students to understand the purpose and relationships of slides and materials, as this ability will contribute to their overall understanding of the subject matter rather than relying solely on memorization.

Understanding Mental Disorders

Mental Disorder Criteria

  • For a condition to be classified as a mental disorder, it must relate to significant distress and impairment in functioning, impacting daily life, social interactions, and overall well-being.

  • Cognitive factors are known to increase vulnerability to mental disorders, often manifesting through negative cognitive biases and interpretations that exacerbate feelings of distress.

Focus on Anxiety Disorders

Panic Disorder

  • Panic Disorder is characterized as an example of cognitive vulnerability, where cognitive framing plays a crucial role in the risk of developing anxiety disorders. This includes experiencing unexpected panic attacks and ongoing fear of future attacks, which can lead to substantial lifestyle changes.

Phobias

  • Specific phobias are irrational fears that can have a debilitating effect on one’s functioning, such as fear of flying or public speaking, leading individuals to avoid certain situations altogether.

  • Prevalence studies indicate that the lifetime prevalence of specific phobias is approximately 12.5%, highlighting the commonality of these experiences among the population.

  • The chronic nature of phobias is frequently reinforced by avoidance behaviors and learning theories, perpetuating the cycle of fear and avoidance.

Learning Theories in Phobias

Classical Conditioning

  • Classical conditioning explains how neutral stimuli can become sources of fear when they are associated with traumatic events. For example, experiencing turbulence while flying may lead to an increased fear of flying.

Preparedness Theory

  • This theory suggests that some fears are evolutionary adaptations that have developed to enhance survival, such as an innate fear of heights or snakes.

  • Different groups of phobias can be categorized as follows:

    • Blood/injury/injections

    • Natural environments (e.g., heights, water)

    • Animals (e.g., spiders, dogs)

    • Situational phobias (e.g., fear of flying or open spaces).

Treatment Approaches

Biological Treatments

  • Benzodiazepines are fast-acting medications that increase the inhibitory neurotransmitter GABA in the body, commonly prescribed for managing acute anxiety symptoms.

  • However, these medications come with risks such as dependence, withdrawal effects, and potential dangerous interactions with alcohol, necessitating careful monitoring by healthcare professionals.

  • SSRIs (Selective Serotonin Reuptake Inhibitors) and SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) are other treatment options that target neurotransmitter dysregulation, though they require a longer duration to observe therapeutic effects.

Psychological Treatments

  • Psychological approaches primarily focus on addressing cognitive vulnerabilities and maladaptive thought patterns.

  • Cognitive Behavioral Therapy (CBT) is a widely used intervention for panic disorder; it emphasizes cognitive restructuring to help individuals identify and modify distorted thinking patterns.

  • Third-wave therapies such as Acceptance and Commitment Therapy (ACT) and mindfulness have emerged, emphasizing flexibility in thoughts and fostering acceptance of uncomfortable feelings as a strategy to manage anxiety.

Generalized Anxiety Disorder (GAD)

  • GAD is characterized by prolonged worry about a variety of issues, persisting for more than six months, and often involves a pervasive sense of dread or apprehension.

  • The treatment plan for GAD often includes CBT combined with exploring acceptance and mindfulness practices to enhance coping strategies and reduce overall anxiety levels.

Essential Reminders

  • The primary focus of the course is not merely on diagnosing disorders but rather on a comprehensive understanding of the cognitive-behavioral model as well as the interaction of genetic and environmental factors in the production and management of anxiety disorders.

  • It is crucial for students to remain proactive by engaging with study materials, participating in discussions, and utilizing practice questions that will be posted in advance to facilitate thorough preparation for assessments.
