Unit 2 Flashcards
anxiety
emotional/ cognitive symptoms (worry, dread) and physical symptoms ( arousal and tension)
anxiety disorder
most common mental disorder
- 1/3 develop at some point
- only 1/5 seek treatment
- women are 2x as likely as men
anx disorder comorbidities
tend to be high with other disorders- depression, asthma, chronic pain, hypertension, IBS
ADs are distinguished by
1) type of objects that are feared
2) content of associated thoughts and beliefs
panic attack
particular type of fear response and common symptom in many anx disorders
unexpected panic attack
no evident trigger- evident of panic disorder
expected panic attack
known trigger= situationally bound and predisposed
phobia
more intense persistent fear (distress) and a greater desire to avoid the feared object or situation
- associated dysfunction
- specific item of fear
phobia diagnostic criteria
1) fear of situation or object
2) immediate anxiety response
3) go to extremes to avoid the situation
4) fear is disproportionate to accompanying danger
5) may have panic attacks associated with phobia
6) must cause clinically significant distress/ social impairment (dysfunction)
7) persistent fear- symptoms must be present for at least 6 months
phobias stats
9% of US have symptoms
many suffer from more than one
women 2x men
vast majority don’t seek treatment
general subtypes
1) animals
2) natural environment
3) situations
4) medical
treatment (phobia)
- exposure therapy
- systematic desensitization (in vivo= place in the feared environment; covert= imagined)
- best= actual contact with feared object
social anxiety disorder
anxiety about being watched by others and fear of being embarrassed or judged negatively
-signif distress or impairment and avoidance
subtypes of SAD
performance- may be narrowly affected by oral presentation, etc
general subtype- broadly affected by social
-in both, people rate themselves as doing more poorly than they are
SAD stats
12% lifetime prevalence
onset= teen years- may follow humiliation
duration is usually life long, but may decrease in adulthood
-comorbidity and self medicating are common
SAD treatment
behavior and cognitive techniques
- group therapy can be helpful
- antidepressants, beta blockers, benzos
antidepressants (SSRIs)
most often prescribed -prozac, celexa, lexapro, Zoloft -taken daily for long term use not addictive appropriate for regular feelings of anxiety
Beta blockers
can help with physical symptoms of social anx
- safe for most patients, few side effects, not habit forming
- propranolol (infernal)-can lower BP
benzodiazepines
found to be effective (1950s) in decreasing anx
- valium, Xanax, Ativan, klonopin
- agonist for GABA
- negative= tolerance builds up and drowsiness (should be tapered off to stop)
panic disorder diagnostic criteria
1)person experiences recurrent panic attacks
AND 2) person is apprehensive about having it for at least one month
OR 3)person develops behaviors designated to avoid PAs
-high comorbidity rate (83% have 1+)
-3-4% of pop (1/4 pop has panic ATTACK at some point)
bio perspective-panic disorder
1) genetic
2) increased amygdala activity (heightened startle reactions and abnormally sensitive neural networks)
3) biochem abnormalities
SSRI
can decrease PAs (1960)
increase serotonin and decrease norepinephrine activity
-bring improvement to at lead 80% of panic disorder patients
agoraphobia
fear of being in public places/ situations where escape may be difficult should they panic or be incapacitated
- typically develops in 20s and 30s
- go to great lengths for avoidance
- must have symptoms for at least 6 months
- create “safe zones” which they do not leave
agoraphobia treatment
- skype/ home therapy (difficult)
- variety of exposure therapy
- support group
- home based self help
- medications to decrease anxiety (+psychotherapy)
generalized anxiety disorder (GAD)
1) excessive/ unreasonable anxiety and worry under most circumstances- free floating anxiety
2) person finds it hard to control the anxiety-“anxious apprehension”= hallmark- frequently checking and diff with decisions
3) physical symptoms (restlessness, fatigue, muscle tension, sleep probs)
4) distress or dysfunction
5) not due to meds or stimulants
6) symptoms must last at least 6 months
GAD stats
6% prevalence in US
appears in adolescence
more common in women (2:1)
shows up in care settings for physical symptoms
disorder worsens during stressful periods
GAD therapies
1) changing maladaptive assumptions (rational emotive therapy)
2) breakdown the worrying (increase self awareness)
3) barbiturates (50s)- addictive and dangerous
- benzodiazepines (60s)- work quickly and addictive
- antidepressants (SSRIS take 2 weeks to work) and azapirones work on serotonin
OCD
recurrent obsessions and or recurrent compulsions (only need one to be diagnosed)
diagnosis:
1)causes great distress or
2)takes up time (>1hr/day)
OR 3) interferes with daily function
-can be paired with trichotillmania, body dimorphic disorder, hoarding, and excoriation
OCD stats
1-2% US in given year (3% prev. over lifetime)
equally common between sexes
40% seek treatment
common obsessions
- contamination
- doubts
- need for order/ symmetry
- aggressive/ horrific impulses
- unpleasant/ unwanted sexual imagery
common compulsions
- cleaning/ washing
- checking
- demanding assurances
- organizing
- counting**
- repeated touching
OCD therapy
- psychoeducation
- SSRIs(prozac)
stress disorder
exposure to traumatic event/ stressor is explicitly listed as diagnostic criterion
symptoms= anxiety, depression (comorbid), dissociation, anhedonia, aggression
stress response
influenced by how we see the event and how we judge our capacity to react to the event effectively
sympathetic NS
hypothalamus excited SNS which stimulates key organs
hypothalamic pituitary adrenal (HPA) axis
hypothalamus signals the pituitary gland which stimulates the adrenal cortex to release corticosteroids into the bloodstream
