Anxiety Disorders Flashcards
Differences between anxiety and fear
Anxiety is a mood, whereas fear is an emotion
Fear is present-oriented, whereas anxiety is future-oriented
Fear is more intense than anxiety
Components of anxiety
Cognitions: apprehension, worry, dread
Behavior: avoidance
Physiology: stress response (cortisol)
Components of fear
Cognitions: danger
Behavior: escape
Physiology: fight or flight sympathetic arousal (adrenaline)
Anxiety disorders general characteristics
Pervasive and persistent anxiety or fear
Intense need for avoidance and escape
Clinically significant distress and/or impairment
Largest mental health problem in US
Anxiety disorders
20% lifetime prevalence
Panic attack
Abrupt period of intense fear that reaches its peak within minutes
Sympathetic response: pounding heart, sweating, shaking, shortness of breath, nausea/abdominal distress, paresthesias (numbing through various parts of body), chills or heat sensation, feeling dizzy or faint, chest pain/discomfort, feelings of choking, derealization or depersonalization, fear of losing control, fear of dying
Specific phobia description
Marked fear/anxiety about specific objects or situations
Exposure provokes a fear response
Object is avoided
Fear is out of proportion to danger
Types of specific phobia
Animal (spiders, mice, etc.)
Situational (small spaces, flying in airplane, etc.)
Natural environment (tornado, thunderstorm, etc.)
Blood injection injury (unique: person passes out)
Other (clowns, dolls, etc.)
Specific phobia epidemiology
Age of onset: teen years (11-17)
Chronic course
4:1 female to male
Relatively high lifetime prevalence (11%)
Specific phobia biological causes
Genetic vulnerability (moderate influence; don’t inherit phobia, but tendency)
BIS
HPA
BIS (Behavioral inhibition system)
Influence in all anxiety disorders
Drive to avoid danger
If high, then cautious
HPA (hypothalamus, pituitary, adrenal)
Influence in all anxiety disorders
Increased activity, then more likely to develop anxiety disorder
Specific phobia learning pathways
Classical/operant conditioning
Vicarious conditioning (observation)
Information transfer (someone tells you to fear something)
Prepared learning: people develop fears to some things more quickly than others (things that posed danger in human history)
Treatments for specific phobia
Cognitive behavioral therapy: exposure, flooding, graduated exposure
Medications rarely used
Exposure
Facing fear and discovering that nothing bad will happen
Used to treat phobias and panic attacks
Flooding
Put person in feared situation until fear response disappears
Not commonly used
Graduated exposure
Systematic desensitization using subjective units of discomfort
Used in treating phobias
Subjective units of discomfort
Patient rates levels of discomfort: 0 is not scary at all, 100 is extremely scary
Start out at low levels of discomfort and work up until patient is desensitized to feared stimulus
Panic disorder description
Recurrent, unexpected panic attacks
At least one month of worry about future attacks and behavioral change related to attacks
Panic disorder epidemiology
Age of onset: teens (11-17) and late 30’s
Course: chronic
33% of ER billing (similar symptoms to heart attack)
Gender: 2:1 female to male
Panic disorder learning pathways
Classical/operant conditioning
Fear response to interoceptive cues (learn to fear panicky feeling)
Cognitive: catastrophic misinterpretations of internal sensations
Panic disorder therapy treatments
CBT
Exposure, especially interoceptive exposure
Cognitive restructuring
Interoceptive exposure
Exposure to physical symptoms of panic attack without fear response
Ex- have patient breathe through straw
Cognitive restructuring
Changing the way people think
Challenging belief system
