Study Notes
Physiological Arousal
- HPA activation (hypothalamic-pituitary-adrenal axis) is a universal human experience
- Affects multiple brain regions and every organ system in the body
- Essential for survival
Concepts Related to HPA Activation
- Stress
- Response to any perceived demand or problem
- Subjective
- Depends on individual coping abilities
- Fear
- Present-oriented response to a real, identified danger
- Marked by a surge in the sympathetic nervous system's "fight or flight" response
- Panic
- Short, intense HPA activation
- Characterized by an abrupt rush of fear accompanied by physiological symptoms, without any real threat
- Anxiety
- Also known as apprehension or apprehensive anxiety
- Future-oriented
- Often triggered by anticipation of a potential future threat
- Characterized by physical tension
Anxiety Disorders
- Occur when anxiety is intense, frequent, excessive (exaggerated threat perception), and causes distress or impairment
Importance of Anxiety Disorders
- Prevalence
- Most prevalent mental health condition in North America
- Estimated lifetime prevalence of 24.9% in the general population (DSM III)
Physiological Arousal
- The body’s innate fear system activates the HPA axis, which affects the brain and all organ systems.
- HPA activation is essential for survival.
Concepts Related to HPA Activation
- Stress is a response to perceived demands or problems that outweigh coping abilities.
- Fear is a response to actual danger, characterized by a surge in the sympathetic nervous system (fight/flight) and an urge to escape.
- Panic is a sudden rush of intense fear and physiological symptoms with no objective danger.
- Anxiety is a future-oriented apprehension about a possible threat.
Anxiety vs. Anxiety Disorders
- Anxiety disorders occur when anxiety is intense, frequent, excessive, and leads to distress or impairment.
Importance of Anxiety Disorders
- Anxiety disorders are the most prevalent mental health problem in North America.
- 24.9% of the general population experience anxiety disorders during their lifetime.
Prevalence of Anxiety Disorders
- Anxiety disorders affect a significant portion of the population, with a 12-month prevalence of 16.4% in primary care settings.
- Even when excluding specific phobias, the prevalence remains high at 18%.
- A concerning 40% of patients experiencing non-cardiac chest pain also have panic disorder.
- Anxiety disorders are not limited to specific demographics; they are present in all cultures but vary in prevalence.
- Notable examples of prevalence include:
- Europe: 8.4%
- USA: 22%
- Australia: 5.6%
- China: 13%
- Canada: 5.8% (for Panic Disorder, Agoraphobia, and Social Anxiety Disorder only)
- Francophone populations: 3.85%
- Anglophone populations: 4.89%
Cultural Factors in Anxiety Disorders
- Studies suggest that anxiety disorders are more frequent in Francophone populations compared to Anglophone populations. This may be attributed to differences in access to and utilization of mental health services in wealthier Anglophone countries.
- A study by Tiwari & Wang (2006) observed higher anxiety rates in Canadians with European backgrounds compared to other ethnic groups.
- Research indicates a consistent presence of anxiety and depression across various cultural groups.
- Defining "culture" presents a challenge:
- Distinguishing between ethnicity and culture.
- Defining research criteria and whether to use a standardized measure.
- Many Canadians identify with a dual cultural identity.
- Individuals from the third generation demonstrate stronger Canadian cultural influences compared to individuals with heritage group affiliations.
- Grouping individuals as "Asian" or "European" may mask diverse experiences within those groups.
- Significant differences exist in specific anxiety disorders between Southern and Northern European cultures.
- Discrepancies in the translation of emotional terms (like social anxiety disorder) can impact diagnosis and understanding across languages.
- Some anxiety disorders, like generalized anxiety disorder or worry, are universally recognized across cultures.
Characteristics of Anxiety Disorders
- Anxiety disorders are often chronic, causing significant personal impairment.
- They are associated with increased risk for other conditions, including depression, suicide, and substance abuse.
- 31% of individuals with anxiety disorders also experience another anxiety disorder.
- 50% of those with anxiety disorders also have depression.
- There is an increased risk of substance abuse among individuals with anxiety disorders.
