Commonality of Anxiety Disorders

Adaptive vs. Maladaptive Anxiety

    • Black and White Thinking:
      • This thought pattern limits perception to absolute extremes, ignoring nuances.
      • Example: Lying awake at night contemplating life goals vs. catastrophic outcomes (e.g., dying alone).
    • Catastrophizing:
      • A process where the consequences of a situation are imagined to be disastrous.
      • Example: Not doing well on a test leads to fears of failing college, homelessness, and eventual death.

Generalized Anxiety Disorder (GAD)

    • GAD is the most generic and widely recognized anxiety disorder.
    • Palpable difference from other anxiety disorders such as Panic Disorder and OCD.

    • Scope: Widespread anxiety over various topics, from serious to mundane issues.
    • Persistence: Difficulty in turning anxiety off; constant state of worry.
