Q

from the stimulation of the hypothalamus how does the adrenal- cortical system respond?

A

releasing hormones like CRF -> pituitary (which releases ACTH) -> andrenal glands and causes many hormones to be released like epinephrine and norepinephrine

Q

why can women experience more severe anxiety symptoms

A

progesterone (usually PMS and postpartum) can affect both serotonin and GABA neurotransmitter systems. increased progesterone can induce mild chronic hyperventilation and in some women this is enough for a panic attack.

-sever impairment with small percentage in China, Mexico, Netherlands, and Romania

46
Q

explain some emotional and cognitive factors of GAD

A

emotions:
-highly reactive to negative events, uncontrollable or manageable
cognitive: maladaptive assumptions (from concerns of uncertainty or losing control) with focus on detecting possible threats in the environment. GAD individuals usually maintain a constant level of anxiety so they dont have to feel a sudden increase from a bad experience

47
Q

what is the stroop-coloring naming task

heightened activity of sympathetic NS and amygdala.
-possible disruption of brain activity coordination
-lower amount of GABA receptors or deficiency resulting in excessive firing of neurons especially in limbic system

49
Q

what are some cognitive behavioral treatments for GAD

A

confront issues of worry, challenge negative thoughts, and develop coping strategies

50
Q

biological treatments for GAD

A

possible drugs like xanax but have side effects and addictiveness and when you discontinue your symptoms will continue

51
Q

what is social anxiety disorder

A

individuals become anxious in social situations and so afraid of being rejected, judged, or humiliated in public that they become preoccupied with these worries they focus on them and possible avoid social encounters

52
Q

what are some things that can have a positive impact on those with social anxiety disorder

A

have a good social support (or a higher level of perceived social support)

53
Q

some characteristics of social anxiety disorder

A
  • when in social situations they may: tremble, perspire, feel dizzy or confused. They think others view their nervousness as weak, stupid, or crazy.
    -key feature is situations are social in nature
    -12 % lifetime prevalence in US and 1-7% internationally
  • women tend to have more severe social fears BUT men tend to seek treatment more
  • can co-occur with other mood disorders
    -in Japan Taijinkyofu-sho is the idea of shame about persistent fear of causing others offense
54
Q

what are some highlights of the cognitive perspective on social anxiety

A

individuals with this disorder have excessively high standards for their social performance and believe everyone should like them
-focus heavily on cues from others they are talking to but may interpret them in a self deprecating way
-avoid eye contact, or social situations all together
- after a social situation they will obsessively go over all part of their performance

55
Q

what are some treatments for social anxiety

A
  • meds like: SSRIs and SNRIs but when you stop meds your symptoms usually come back
  • Cognitive behavioral therapy: behavioral component includes exposing client to situations that illicit anxiety and cognitive component: identify the negative cognitions client has about themselves and social situations and teaching them how to see these are wrong. Could be in group setting and also teaching relaxation techniques
    -ACt: mindfulness based working on acceptance. and values to become more focused and relaxed in present moment than judging themselves
    -also starting to make internet based therapy and can meet those patients who are unable or unwilling to use traditional treatment delivery
56
Q

define specific phobias

A

unreasonable fear associated with specific objects or situations

57
Q

what are the five categories of specific phobias in DSM

A

animal, natural environment, situational, blood-injection, and other

58
Q

what are the key symptoms to diagnose specific phobia

A

fear of specific object or situation with that does not correlate to actual risk or danger
-avoidance or intense fear during event
-symptoms of at least 6 months
-clinical distress or impairment that cannot be better defined as relevant to other mental disorder
- when presented with these objects or situations individual experiences immediate spike in fear that could turn into panic attack and anxious over encountering experience again

59
Q

animal type phobia

A

most common are snakes and spiders - can live in terror of encountering them or create life around ways to avoid them

60
Q

natural environment phobias

A

events of situations like storms, heights, or water. typical survival tactic to fear these things but becomes phobia when you organize life in way to avoid them

61
Q

situational type phobia

A

can include bridges, elevators, flying, driving, etc.

62
Q

blood-injecting-injury phobia

A

seeing blood or injury - likely to faint when they see. Runs more strongly in families compared to other phobia types

63
Q

agoraphobia

A

fear if they cannot escape when they become anxious - 50% have panic attack history and the rest struggle with history of other forms of anxiety disorder

64
Q

behavioral theories of phobias

A

classical conditioning leads to fear of object and operant conditioning maintains it. when people avoid what causes their anxiety it becomes a negative reinforcement
- we typically avoid objects that in the past would have been advantageous for evolutionary purposes
- usually those with phobias can not correlate it to a specific traumatic event
-without conditioned stimuli hard to argue phobia is developed through classical conditioning or observational learning
- individuals may just have chronic anxiety which makes them more susceptible

65
Q

define prepared classical conditioning

A

from evolutionary history we are engrained in some areas to quickly learn associations that may result in a phobia - this theory was tested. Using photos of evolutionary conditioned stimuli (snakes and spiders) and non conditioned (houses, flowers, faces) each photo was paired with a shock. it took longer for fear response to photos of houses and flowers compared to snakes. It took longer to “unlearn” fear response when viewing photos of spiders compared to flowers

66
Q

what is the biological theory of phobias

A

1st degree relatives 3-4 times for likely to have phobias

67
Q

treatments for phobias

A

-behavioral therapy: systematic desensitization, modeling, and flooding
- in blood phobias they are taught to tense muscles in arms, legs, to make blood rise to face and increase blood pressure (applied tension technique)
-modeling technique: therapist does action first to show client they do not need to worry
-flooding: is showing client their worst fear and leaving them with it for extended amount of time (ex. fear of dogs so client is left in with dogs in a room overnight) harder to get clients to do this type of therapy

68
Q

biological treatment for phobias

A

may provide short term relief from symptoms but does not correct the phobia and drugs have side effects and are easily addicting

69
Q

describe obsessive-compulsive and related disorders

A

all share an obsessive-compulsive component and examples include: (OCD, hoarding disorder, body dysmorphic disorder, trichotillomania (hair pulling), and excoriation (skin picking) they are all related by repetitive behaviors, age of onset and comorbidities, brain circuitry and neurotransmitter abnormalities

70
Q

define OCD

A

describes individual with obsessions, compulsions, or both. usually obsessions revolve around certain themes (germs, prevent harm or bad luck, forbidden thoughts, symmetry and order) the compulsions usually happen as a way to neutralize and reduce anxiety and distress. Will create rituals that are deliberate, purposeful, and goal oriented

71
Q

what is an overt compulsive ritual

A

behavioral compulsions
- excessive decontamination
-counting or repeating routine actions

- strong correlation with impulse-control and substance use disorders as well
- world wide 1-3% will develop

75
Q

define trichotillomania

A

pulling hair (scalp, eyebrows, pubic) and some dont realize they are doing the action (automatic) while others say a hair does not feel right so they pick it (focused)
-impacts for females to males usually develops around 10-13yrs old

76
Q

define excoriation

A

picking at skin and they cannot stop but feel shame or social embarrassment

77
Q

how OCD, hoarding, trichotillomania, and excoriation are connected

A

acts are repetitive, behavioral inhibition, and individuals feel tension before and trying to stop themselves and then immediate relief when they complete their behavior

78
Q

characteristics of those with body dysmorphic disorder

A

excessive concern about physical appearance and do not feel less distressed when others tell them their concerns are not real. Create compulsive rituals to “check” their flaws can spend 3-8 hours a day on these preoccupations and may seek surgery to check
-usually presents around 16 (and equally impacts males and females)
- high comorbidity with depression, substance abuse,
- social media makes it much worse
- high associated with suicide
- if excessive may begin to show delusional thoughts
- 80% of individuals with BDD have a lifetime suicide ideation

79
Q
A
80
Q

what are the biological theories around OCD and related disorders?

A

in OCD, trichotillomania, and excoriation individuals show alternations in structure and function of frontal cortex, basal ganglia (specific striatum) to thalamus, anterior cingulate cortex

81
Q

what are the brain alternations based on the biological theories for hoarders

A

dysfunction in structure and activity levels of frontal cortex and limbic system

82
Q

brain alternations based on bio theories for those with body dysmorphic disease

A

alternations in processing visual stimuli

83
Q

Cognitive behavioral theories around OCD

A

have inability to turn off negative intrusive thoughts
-may be generally anxious and makes negative events create more negative intrusive thoughts
-believe their thoughts are more unacceptable
- these negative thoughts cause compulsions through operant conditioning (rituals of praying before handling baby - makes less anxious so continue to do it to stop bad feeling or negative reinforcement)

84
Q

cognitive behavioral theories around hoarding

A

exaggerated sense of responsibility, feel guilty wasting things and want to be ready for ‘just in case’ scenarios. Also think they have bad memory and need to keep things in site to know what they have

85
Q

cognitive behavioral theory around BDD

A

negative interpretations of perceived flaws and overvaluation

86
Q

biological treatments for OCD and related disorders

A

can use SSRI’s but only help to a certain degree and symptoms usually return when drug is discontinued - but also have significant side effects

87
Q

cognitive behavioral treatment for OCD

A

combine CBT and exposure and response prevention (expose to obsessions without allowing compulsive behavior) while CBT focuses on challenging thoughts on excessive thoughts of responsibility
-69-90% clients saw improvement

88
Q

CBT for hair and skin picking

A

focus on habit reversal training so they become aware of tells and cues to replace behavior

89
Q

CBT for BDD

A

focus on feared situations concerning body parts and hierarchy of learning calming skills to tackle most fears areas and allowing others to seem them in public for example

90

92
Q

what is a PTSD flashback as part of experiencing symptom

A

individuals re-experience traumatic event and cannot tell what is reality or just a memory. could be triggered by something in environment (like smell) or nothing at all. They are emotional intrusive memories of highly selective neural hotspots which are personally significant to the individual

93

how does ethnic identity relate to psychological factors

A

usually ethnic identity established during adolescents has positive association with self-esteem, coping, sense of mastery, and optimism (protective factor)

104
Q

biological factors associated with PTSD

A

PET scan shows differences in amygdala, hippocampus, and prefrontal cortex (areas involving emotional regulation)
-amygdala responds more actively (responsible for processing emotional and threat info)
-medial prefrontal cortex: usually moderates amygdala response is less active
-shrinkage of hippocampus: usually helps with memory but in PTSD individuals may have memory loss and lower control over fear response

105
Q

biochemical findings of PTSD

A

-possible lower levels of cortisol = prolonged SNS activity
-HPA axis shut down and cant respond to neurotransmitters released for SNS
-childhood stress
- genetics: heritable risk of low cortisol levels

106
