Anxiety Disorders Flashcards
Define fear
Emotional response to real or perceived imminent threat
Define anxiety
Anticipation of a future threat
What is most a/w ANS arousal - fear or anxiety?
Fear
What is anxiety most associated with in relation to body response?
Hyper-vigilance and muscle tension in preparation for future danger
How do anxiety disorders differ from general fear/anxiety?
Anxiety disorders are excessive or persist beyond developmentally appropriate periods (a 4 yr old being scared of monster in the closet is appropriate vs. a 51 yr old)
Who is MC affected by generalized anxiety disorder (GAD)?
- Females 2:1
- Diagnosis peaks in middle age (decreases in later years)
Etiology of GAD
- Learned
- Cognitive theory (anxiety results from incorrect views of oneself, the environment, future)
- Neurobiology (abnormal functioning of serotonin and cortisol, increased NE)
Proposed neurobiological model of GAD?
- Hyperactive amygdala results in hyperactive ANS activity and cortisol secretion
- Chronically increased cortisol results in increased serotonin uptake and other changes
Clinical presentation of GAD
- Excessive and persistent worrying
- Hyperarousal, muscle tension
- HAs, neck/shoulder pain w/o specific cause
How to diagnose GAD?
- 3 or more symptoms (present on more days than not) for over 6 months
- GAD 7 scale (99% negative predictive value)
Treatment of GAD
Psychotherapy/CBT (along with some meds)
Pharm treatment of GAD
Use anxiolytics (short acting)
- BZD used with SSRI/SNRI
- Buspirone (no abuse potential, no cognitive impairments, takes longer than BZDs, may work better w/SSRI or SNRI)
- SSRIs and SNRIs
Define panic disorder

- Meds (SSRIs, BZDs, MAOis)
What meds are used for general social phobias vs. specific phobias?
- General social: SSRIs, BZDs, MAOis
- Specific: BBs 1 hr before, can give small BZD dose w/it
What is the MC mental disorder in the US?
