Q

how to break the panic attack cycle

A

this is not a panic attack
i will be fine
deep breathing (but avoid hyperventilization)
re-attribute physical symptoms
also grounding eg stamp feet or squeeze fists
mindfullness, progressive muscle relaxation

Q

bio contributions to anxiety and panic (specifics!)

A

GABA circuits - depleted
Corticotropin releasing factor (CRF) and HPA axis
limbic (amygdala) and septal-hippocampal system (emtional valence of incoming info) - central to expression of enxiety and depression
noredrenergic and serotinergic implicated

Q

treatment of GAD

A

some help from meds
-benzodiazepines = short term as addictive (basically feel drunk the whole time so big congitive effects - falling down the stairs etc)
-SSRIs are less good but less side effects so good 2nd choice
psych = CBT
-confront emotions
-acceptance of distressing thoughts not avoidance
-meditation / MBCT

Q

panic disorder overview and features

A

in DSM5 no longer linked to agoraphobia
recurrent unexpected panic attacks - so false alarms
worry about next panic attack or what they mean
just a panic attack does not equal panic disorder
interoceptive and exteroceptive avoidance of situations
catastrophic misinterpretation of symptoms (clinical conditioning model)
so post panic attack = persist concern or worry about it or a significant maladaptive change in behvaiour

female 2:1 (even higher female in severe cases), maybe as men just cope by alcohol and drugs
acite onset
early/ mid 20s
panic attacks begin during puberty usually
decrease in elderly - prehaps less concern over health and vitality

medications used to treat panic disorder

A

SSRIs = preferred
relapse rates - high (50%) following discontinuation but all good if stay on meds
idea of pill as a crutch - reverse to placebo when meds stopped?
SNRIs (serotonin, neuropinephrine reuptake inhibitors)

Q

psych and combined treamtments for panic dis

A

cognitive behaviour therapies = highly effective = PCT or panic control treatment goal is to break the link between cue and panic / catastrophic event = gradual exposure and modification of perceptions and attitudes
combined treatments do well in the short term
best long term = CBT alone
drugs can interefere with CBT = so sequential treatment may be best ie if one approach doesn’t work try another
also must balance rapid repsonse of meds compared to psych can be worth it
may already be taking drugs = best to add in CBT, stepped approach

Q

what is agoraphobia

A

fear or avoidance of situations / events assocaited with panic
situation / event evokes disproportionate anxiety almost always
active avoidance
6 months
clinical sig
info transmission - don’t have to have a panic attack in that place to think you might
can be relatively independent of panic attacks
agora = marketplace
alcohol and drug abuse can occur but some od manage to work

Q

treatment of specific phobias

A

CBT = highly effective - challnege thoughts
exposure treatment:
-systematic desensitization = learn to relax, bottom of hierarchy (least feared situation), bring down to relaxed state, continue to move up the hierarchhy training to stay relaxed in each situation. can be done in one day like snake video or over the course of several weeks
-flooding = all at once emersion, no gradual exposure, risky as what if something does actually go wrong = set back

48
Q

PTSD and the brain

A

all limbic
hypoactive prefrontal cortex
hyperactive amygdala (actively looking for threats, fires too easily)
shrinking hippocampus

49
Q

3 PTSD subtypes / onset

A

delayed expression - full criteria for more than 6 months
acute stress disorder - immediately post-trauma but only more than 1 month (made to get round insurance problems to help those who are struggling)
dissociative phenotypes - more difficult to treat, less physiological arousal and more feelings of unreality

50
Q

causes of PTSD

A

intensity of the trauma and ones reaction to it
uncontrollabilty and unpredictability
direct conditioning and observational learning
moderator = social support, if good social support hugely beneficial, eg vietnam = unpopular war = high incidence PTSD, lack of social support?

51
Q

common problems with PTSD

A 
alcoholism and substance abuse
suicide
depression
chornic pain
traumatic brain injury (veterans and domestic violence cases)
52
Q

treatment of PTSD

A

CBT = highly effective
-just world belief system = i was a soldier so i deserve this
-adress cognitive distortions
exposure therapy = not to erase memories but manage them and take back control over them
-graduated or massed (eg flooding) through imaginal exposure
VA approves cognitive processing therapy, EMDR (weird wave finger side to side, wasn’t peer reviewed, $$$), prolonged exposure therapy

53
Q

how type of stressor promting PTSD differs with treatment

A

single stressor eg raped once responds better to treatment than prolonged eg years of sexual abuse or in a war zone

54
Q

what are obsessions

A

intrusive, anxiety producing thoughts, images or urges

55
Q

what are compulsions

A

repetitive behaviours or mental acts to counteract anxiety or prevent occurence of dreaded event
-overt = washing etc
-covert = sequencing, repetition, counting
more than 1 hour a day
aimed at reducing anxiety or distress or prevent some dreaded situation = excessive, not realistic

56
Q 
stats OCD
-gender
-onset
-course
note on tics
A

slightly more women than men (boys earlier onset)
onset in early adolescence or young adulthood
tends to be chronic
tics are not compulsions but 10-40% of children and adolesence with OCD = tic disorders at some point
looks very similar accross cultures

57
Q

OCD causes

A

biopsychosocial like other anxiety dis
early life experiences and learning - some thoughts are dangerous but controllable
thought-action fusion - moral vs likelihood eg thinking about abortion is the same as having an abortion

58
Q

multisite study of OCD treatment mentioned in lectures

A

aim - compare independent and combined effects of clomipramine and exposure-response prevention (ERP)
drug alone
ERP alone
drug + ERP
pill placebo alone
all were good short term compared to placebo. but drug alone = very high relapse rates once drugs stopped, ERP alone = no significant relapse, combined treatment was somewhere in the middle

59
Q

body dysmorphic disorder overview / clinical description

A

now part of obsessive compulsive and related dis
preoccupation with imagined defect
fixation or avoidance or mirrors
suicidality
ideas of reference - everything in the world relates to me
always relevant to cultural standards so maybe just an exaggeration of what is culturally determined?

60
Q

BDD course, onset and gender

A

lifelong and chronic
more common than thought
seen equally in males and females ( more severe in men)
onset usually early 20s - higher in college students and arty/design people
most remain single, seek out plastic surgery, dermatology etc
used to be considered somatic but intrusive thought problems = more OCD like
suicide ideation typical
ideas of reference problems
poor life - not married, suicide, depression etc

61
Q

causes BDD

A

unknown
runs in families
OCD relation

62
Q

treatment of BDD

A 
SSRIs = some relief
CBT / ERP
exposure and response prevention
plastic surgery = usually unhelpful
outcomes very similar to OCD
63
Q

what is panic

A

sudden overwhelming fear or terror

64
Q

environmental factors in sensitivity of brain circuits

A

can make you more sensitive so more susceptible
eg smoking cigarettes as a teenager associated with increased risk for developing anxiety disorders as an adult (paritcularly panic and GAD) = chronic exposure to nicotine triggers additional anxiety and panic so bio vulnerability increases

65
Q

limibic brain in anxiety patients

A

overly responsive to stimulation or new info = abnormal bottom up processing
at the same time controlling functions of the cortex that would down regulate the hyperexcited amygdala are deficient (so abnormal top-down processing)
=consistent with BIS

66
Q

cultural differences in reporting anxiety

A

tiny in china, large in mexico
reporting differences?
psych manifestations differ - so using western standards = not applicable
willingness to report anxiety in some cultures eg in the west men often turn to alcoholism insteas

67
Q

childhood awareness events not always in our control….

A

general sense of uncontrollability can develop early
parents foster this = eg good if parents respond to needs in a predictable way and positive interactions as this teaches children they have control over their environment. also allowing a secure home base child can explore themself from = healthy

68
Q

anxiety and sleep

A

difficulty sleeping seems to make anxiety worse

69
Q

GAD and age

A

insidious onset
tends to be diagnosed around age 30
but is definitely and older disease
maybe related to how we care / see elderly in our culture
also must watch benzo use in eldery - falling down the stairs, fragility etc

70
Q

study of autonomic restrictors in GAD but cognitive processes

A

did restrict autonomic arousal but
showed intense cognitive processing in frontal lobes (EEG), particularly left hemisphere
= thought process without imagery as imagery = right hemisphere
don’t have mental capacity to create images which would elicit ANS
so therapy = force imagery

71
Q

2 studies for treating GAD

A

primary care setting treated nurses and doctors where GAD = frequent complaint
-used CBT to deal with provoked worry in therapy then applied outside
-brief cognitive treatment altered unconscious biases of those with GAD
94 9-13 yo
CBT or waitlist
based on teacher ratings, 70% of treated children were functioning normally after treatment with gain maintained for 1 year after

72
Q

panic disorders in other cultures

A

same incidence world wide
greater emphasis on somatic symptoms in third world countries (emotions not always a big part of their culture)
ataques de nervios - carribbean, hispanic americans = more shouting and tears
kyol goeu - cambodian wind overload

73
Q

when are panic attacks most liekly to occur

A

1:30am - 3:30 am as delta or slow wave sleep = deepes stage of sleep
awaken during panic of falling into deepest sleep = most think they are dying

74
Q

what causes nocturnal panic

A

changes in stages of sleep produce physical sensation of letting go = frightening for someone with a panic dis
nightmares during REM do not dreams

75
Q

sleep terrors

A

children scream and get out of bed but report no memory
but nocturnal panic is remembered so is different
sleep terrors tend to occur in a late stage of sleep - stage 4, a stage also associated with sleep walking

76
Q

isolated sleep paralysis

A

culturally determined
transtional stage between sleeping and waking
during this period individual unable to move = surge of terror resembling panic attack, can be accompanied by vivid hallucinations
REM spilling into waking?
sig higher in aa with panic dis

77
Q

clark cognitive theories

A

emphasises specific psych vulnerabilities of people with this disorder to interpret normal physical sensations in a catastrophic way
anxiety = more of a physical sensation as increased action of sympathetic nervous system = more danger and viscious cycle
Clark = cognitive processes as most important in panic dis

78
Q

4 major subtypes of phobias

A

blood-injection-injury
situational (planes, elevators, encolsed places)
natural environment
animal type
fifth = other
people tend to have mutliple phobias of different types

79
Q

situation phobia

A

originally thought similar to agoraphobia
mid teens / 20s (like agoraphobia)
similar familial as agoraphobia
but no panic attacks outside of specific phobia

80
Q

natural environment phobia

A

fear of situations or events in nature, esp heights, storms and weather
must substantially interefere to be a phobia remember
7 yo onset

81
Q

animal phobia

A

unrealistic enduring fear of animals/insects
develops early in life
again intereferes with functioning

82
Q

stats of specific phobia

A

most common psych dis in US and around the world
4:1 female:male
only most severe need treatment / come for treatment, most simply avoid phobic situations
chronic
decline with old age
hispanics = x2 more likely than other americans
pa-leng - chinese fear of cold

83
Q

how you can cause a specific phobia

A

direct experience
experience a false alarm in given situation
viacrious experience - watch someone elses severe fear
information transmission - being told about it

84
Q

phobias in families

A

“breed true” so exact specific phobia is passed down through families (genes or modelling?)

85
Q

how to treat blood-injection-injury phobia

A

taught how to increase bp, often 2-6 hour therapy session
continue to practice at home
phobia dissapears and vasovagal response at sight of blood lessens considerably = brain rewiring as diminished responses in fear sensisive network

86
Q

separation anxiety disorder

A

excessive, enduring fear about being apart from caregiving loved ones such as spout or parent
something bad will happen
children might refuse to go to sleep alone or school
all young children experience this at some point but tends to decrease as you get older = clinican must judge if getting abnormal
must distinguish from school phobia
if severe can continue into adulthood
=new DSM5 category

87
Q

treatment of separation anxiety disorder

A

parents included - their reactions might need to change

some try therapist coaching parent in earpiece

88
Q

social anxiety disorder

A

extreme, enduring, irrational fear and avoidance of social or performance situation - also called social phobia
the social situation must almost always produce fear / be endured with intense fear / anxiety
must be out of context to social situation / culture
subtype = performance anxiety

89
Q

stats of social disorder we care about (onset, gender etc)

A 
equal male to female
adolescent onset (peak 13yo)
young, uneducated, single, low SES
much less common in elderly
white americans = most likey americans
japanese have own version = more male, fear of body odour / their body will upset others - olfactory reference syndrome
90
Q

causes of social phobia

A

we learn more quickly to fear angry expressions than other facial expressions & fear diminishes more slowly
- even more true in those with social anxiety
evolutionary basis we think
study showed some babies are born with a tempermament profile of inhibition or shyness that is evident at 4 months
severe bullying as teenager
emphasis on social evaluation

91
Q

treatment of social phobia - psych

A

therapy program emphasising real-life experiences to dipose automatic assumptions of danger
IPT - interpersonal psychotherapy
maintains as they avoid / enagage in safety behaviours - so social mishap behaviour = directly challenge beliefs
CBT in adolescence (families if parents have anxiety dis too)

92
Q

treatment of social phobia - drugs

A

assumed beta-blockers would help - did not
SSRIs
mixed results on studies trying to understand conbined treatments

93
Q

DCS drug in rats

A

worked on the amygdala, unlike SSRIs this drug worked to facilitate extinction of anxiety by modifying neurotransmitter flow in glutamate system

94
Q

selective mutism

A

developmental disorder characterised by a consisitent failure to speak in specific social situations despite speaking in other situations
-driven by social anxiety (high morbidity with social phobia)
-must occur for more than 1 month and this cannot be the first month of a new school
parents at fault - they talk for them?
treatment = CBT, highly specialised programs eg camps

95
Q

trauma and stressor related disorders are distinct

A

origin in stressful events

96
Q

PTSD - trauma exposure study

A

9/11 the closer lived to building coming down = greater incidence of PTSD
=have to be close encounter with trauma

97
Q

PTSD twins study

A

same amount of combat exposure, MZ twins are more likely to develop PTSD than DZ twins if other twin had PTSD
= some genetic influence
also stress diathesis model

98
Q

study of female undergrads who withnessed shooting

A

all experience same traumatic event
serotonin transporter gene ss = increased probability of becoming depressed and experiencing symptoms of acute stress
tendency to be anxious as well as minimal education predicted exposure to traumatic events and therefore increased risk of PTSD (don’t think this was found in shootout study but is relevant)

99
Q

when do vulnerabilities matter in PTSD

A

when stress levels arent high as when very high = PTSD

so vulnerabilities only relevant at medium / low levels

100
Q

some protective PTSD factors

A

family stability
strong social support = broad and deep
positive coping strategies

101
Q

impact of broad and deep social system - brain wise

A

loved ones reduce cortisol secretion and HPA axis activity in children during stress
maybe why vietnam vets so high PTSD as unsupported war

102
Q

brain damage / change in gulf war and holocaust survivors with PTSD

A
