Q

Cognitive Techniques for Worrying

A
  • Helpful vs. unhelpful worry:
  • Is there something that can be done about this in the next 24 hrs? -> If so, stop worrying and start acting.
  • Likelihood questions:
  • What is the worst case scenario? What is the best case scenario?
  • How likely are each?
  • Importance Questions:
  • If the worst case scenario happens, can you deal with it?
  • How important do you think this will be 5 years from now?
  • Acceptance of Uncertainty
  • We do things every day that are potentially dangerous: Driving, crossing the street, eating at restaurants, smoking
  • We can never predict what will happen in life
  • People usually consider their greatest accomplishments to be how the overcame adversity
  • Life would be boring if we could always predict the future and nothing bad every happened

63
Q

OCD: About of patients will respond to monotherapy

with SSRI

A

40-60%

64
Q

OCD: Augmentation with may help treatment resistant

have de novo or worsening of OCD symptoms with
SGAs, especially clozapine

Q

Cognitive Techniques OCD

A
  • Normalization of obsessions: Intrusive thoughts along lines of obsession themes are common in general population. Becomes pathological due to importance and meaning attached to the thoughts (e.g. If I have the thought of drowning my baby, it means I’m a horrible person)
  • Role of neutralization: Attempting to suppress the thought makes it occur more often (e.g. “Don’t think of a pink elephant!”). Goal is to have patient “do nothing” in response to obsession.
72

77
Q

BDD treatment pharmaco

A
  • SSRIs and clomipramine at high doses for long duration (12-16 weeks) most effective
  • No evidence that presence of “delusion” requires treatment with antipsychotic. Instead, implies a more severe form of BDD
  • Only 22% of patients who tried SRI had a “minimally adequate” trial
  • Open studies suggest potential benefit from buspirone + SSRI, SGAs +SSNRI
78
Q

BDD psychotherapy

A

• Often requires motivational interviewing (exploring pros + cons of change)
• Exposure and response prevention
• Perceptual retraining – nonjudgmentally describe their entire body in a mirror for 5 min from an arm`s length away
• Identify maladaptive beliefs: “As long as I have this deformed nose, no one will love me and I will
never be happy”
• -> “Even if my nose is deformed, I can still live a meaningful life. There is more to a person than their outward appearance.”

79
Q

Communicating with BDD Patients Don’t

A
  • Say that there is “nothing wrong with them”

85
Q

Hoarding D/O vs OCD

A
  • Phenomenology

Treatment hoarding

A
  • Poor outcomes with traditional CBT for OCD

Q

Anxiety disorders: More common in women or men?

A

women

95
Q

Impacts of anxiety disorders

A

Decrease work productivity, increased use of healthcare services. Increased risk for suicide.

96
Q

Etiology of anxiety

A

Cell bodies of origin for the serotonin pathways lie within the raphe nuclei located in the brain stem. Serotonin is thought to be decreased in anxiety disorders. Cell bodies for norepinephrine originate in the locus ceruleus. Norepinephrine is thought to be increased in anxiety disorders. GABA is the major inhibitory neurotransmitter in the brain. It is involved in the reduction and slowing of cellular activity. It is synthesized from glutamic acid, with vitamin B 6 as a cofactor. It is found in almost every region of the brain. GABA is thought to be decreased in anxiety disorders (allowing for increased cellular excitability).
Hereditary, genetic, learned beahviors
HPA axis: stress= cortisol = increased arousal, vigilance, focused attention, memory formation, inhibition of the growth and reproductive system containment of the immune response
Stressors = neurophysiological changes
Childhood trauma
Temperament: behavioural inhibition

97
Q

Areas of the brain affected by anxiety disorders and the symptoms that they mediate include the following:

A
  • Amygdala: Fear; particularly important in panic and phobic disorders
  • Hippocampus: Associated with memory related to fear responses
  • Locus ceruleus: Arousal
  • Brainstem: Respiratory activation; heart rate
  • Hypothalamus: Activation of stress response
  • Frontal cortex: Cognitive interpretations
  • Thalamus: Integration of sensory stimuli
  • Basal ganglia: Tremor
98
Q

How does anxiety affect thinking, perception, learning, and attention?

A

By biasing attention, anxiety alters what we are conscious of, and in turn, the way we experience reality. More difficult to learn, attention is focused on threat, heightened senses focused on the threat but everything else falls away. Thought process is distorted. Selective attention. Decrease concentration, reduced ability to make recall associations. Brain fog, senses decreased. Feelings of unreality.

99
Q

Comorbid with OCD

A
