Q

Panic Attacks versus Panic Disorder

A

Panic attack is not a mental disorder and can occur in the context of any anxiety disorder; can be noted as a specifier

Q

Panic Disorder Symptoms Domains

A
  • Cognitive: focus on immediate threats, interpret ambiguous stimuli as dangerous
  • Somatic: respiratory and cardiovascular primarily, but also nausea, loss of bodily control, sweating, dissociation
  • Behavioral: mostly avoidance

Q

Initial Panic Attack

A
  • Fear = natural response to a threatening stimulus
  • First panic attack like a false alarm; don’t know why it happened
  • First attack usually occurs away from home, in public, and while active
  • Bodily sensations perceived as threatening

Q

Interoceptive Conditioning

A
  • Somatic arousal related to anxiety becomes conditioned stimulus (i.e., associate somatic arousal with the bad situation the person was in)

Q

Catastrophic misappraisals of bodily sensations

A
  • Sensations interpreted as signs of imminent death or loss of control (e.g., person climbs a flight of stairs & their hear rate changes; person attributes this to early signs of a panic attack and works themselves up)

Q

Maintenance of Panic Attacks

A

Distress over bodily sensations (fear of fear) ongoing:
1) Cycle of fear about bodily sensations considered a positive feedback loop, triggered by autonomic arousal
2) Seems to start out of the blue; perceived as uncontrollable, which adds to anxiety (When is it going to happen again?)
Increased apprehension = increased availability of/alertness to bodily sensations related to panic

Q

Initiation and Maintenance of Panic Disorder Model

A

Unknown stimulus –> first attack –> fear of fear –> increased arousal –> sensations as stimuli/catastrophic misinterpretations –> panic attack –> heightened apprehension –> back around the loop (increased arousal) OR avoidance behavior leading to agoraphobia

Q

Agoraphobia DSM-5 Diagnostic Criteria

A
  • Marked fear of 2 or more:
    1) Public transportation
    2) Open spaces
    3) Enclosed spaces
    4) Standing in line or being in a crowd
    5) Being outside of home alone
  • Fears driven by thoughts that escape would be difficult or help would not arrive
  • Situations are persistently fear provoking and are actively avoided (or require presence of companion/are endured with intense fear)
  • Fear out of proportion to actual danger posed by situation
  • 6+ months

Q

Generalized Anxiety Disorder DSM-5 Diagnostic Criteria

A
  • Excessive anxiety/worry (apprehensive expectation, or feeling that something bad is going to happen) about a lot of things for at least 6 months
  • Worry is difficult to control
  • Worry is associated with 3+ of following:
    1) Restlessness
    2) Fatigue
    3) Concentration difficulties
    4) Irritability
    5) Muscle tension
    6) Sleep disturbance

Q

Specific Phobia Epidemiology & Etiology

A
  • Point estimate: 7-9%
  • More common females 2:1
  • Age of onset can differ by type of phobia
  • Preparedness: why afraid of some things but not others? Possibly evolutionary?
  • Classical conditioning
17
Q

Social Anxiety Disorder Epidemiology & Etiology

A
  • Very common (lifetime 12%, point 7%)
  • More common in women
  • Onset: ages 13-20
  • Genetic: moderately heritable; gender differences in twin studies (50% variance in females, 25% men)
  • Temperament
  • Parents may model anxious behavior; overprotectiveness or parents low in emotional support
  • Biological: serotonin involved but role unclear; dopamine involved (MAOIs reduce symptoms)
18
Q

Social Anxiety Disorder Symptom Domains

A
  • Somatic: panic attack-like symptoms, but only in social situations
  • Cognitive/Psychological: thoughts of social inadequacy, concerned others are aware of own distress, fear of embarrassment, biased to attend to indicators of negative eval
  • Behavioral: avoid social situations, some have specified fears of eating/drinking in public, often interfere with performance, excessive alcohol use common
19
Q

Epidemiology of Panic Disorder

A
  • Point prevalence 2-3% (5% lifetime)
  • More common females (2:1)
  • Onset tends to be sudden, early 20s
20
Q

Etiology of Panic Disorder

A
  • Genetics: family/twin studies show genetic influence (30-40% of variance)
  • Environmental: stressors often associated with initial panic attacks
  • Classical conditioning: How much does an event affect you and do you make associations to the event?
  • Diathesis-stress approach
  • Psychological factors: fear of fear; usually more sensitive to bodily sensations (scan bodies)
  • Biological factors: amygdala dysfunction, low GABA (inhibitory) levels, dysregulation of autonomic nervous system and HPA axis (don’t have balance sympathetic and parasympathetic nervous systems), serotonergic systems implicated
21
Q

Epidemiology of Generalized Anxiety Disorder

A
  • Point prevalence 1-2%, lifetime 4-6%
  • Age of onset typically in early adulthood: often describe lifelong difficulties but don’t realize problematic; onset slow and gradual
  • Twice as common in women than men
22
Q

GAD: Biological Perspective

A
  • Genetic factors: increased risk in blood relatives (could be modeling?)
  • Neurotransmitters: GABA (inhibitory) low, serotonin low?, norepinephrine elevated?
  • Autonomic inflexibility: low autonomic reactivity, higher, unstable heart rate and state of heightened arousal
  • HPA Axis: cortisol over-production
  • Prefrontal Cortex: cognitive inhibition –> worry/rumination
23
Q

GAD: Cognitive Perspective

A
  • Theory: GAD is caused by maladaptive assumptions
  • Ellis: basic irrational assumptions applied to everyday life
  • Beck: GAD as unrealistic, silent assumptions that imply imminent danger
24
Q

Probability Overestimation

A
  • Worries themselves not necessarily unreasonable
  • Overestimate likelihood of negative consequences (interpret ambiguous events as threat, overestimate likelihood of bad events)
25
Q

Problem Solving & GAD

A
  • Worry in small portions may be adaptive

- Excessive worry associated with poor problem-solving or low confidence

26
Q

Information Processing & GAD

A
  • “Pay greater attention to threatening stimuli, preferentially encode this info, have biases in memory for threatening events”
  • Interpretation of ambiguous stimuli as dangerous/negative
27
Q

Avoidance Theory

A
  • T. Borkovec
  • Worry is attempt at cognitive avoidance –> prevents full emotional experience of anxiety (distracting)
  • Reduces distress and fear in short-term
  • Worry is employed to prolong and maintain a negative emotional state thereby avoiding an unexpected negative emotional shift
28
Q

Intolerance of Uncertainty & GAD

A

They would rather know what is going to happen, even if it’s bad; anxiety about uncertainty

29
Q

GAD: Sociocultural Perspective

A
  • Negative social conditions: stressful life events that are unexpected, negative, and very important –> increased risk
  • One of the most powerful forms of societal stress is poverty; high rates of GAD in low SES & among ethnic minority groups
30
Q

Common Age-Appropriate Fears in Children

A
  • Infants: loss of support, loud noises, height, strangers, sudden & unexpected objects
  • 1-2: separation from parent, strangers, toilet injury, loud noises, large animals
  • Preschool: animals, the dark, masks, being left alone, insects, separation from parent
  • Elementary School: animals, the dark, thunder & lightening, supernatural beings, current events
  • Middle School: academic, social, and health-related fears (e.g., tests, medical procedures)
31
Q

When is a child too fearful?

A
  • Intensity: fear more intense than expected given the child’s age, gender, etc.
  • Duration: continues beyond what is considered normal age
  • Impairment: fear interferes with child’s normal activities
