23
Q

A behavioral model of OCD suggests that people sustain
conditioned responses as habits long after the contingencies that conditioned the initial behavior have
shifted. Thought suppression may exacerbate tendencies toward obsessions, and thought–action fusion
may increase the likelihood of thought suppression.

A

oke

24
Q

Cognitive behavioral models of hoarding disorder focus on …

A

poor organizational abilities (difficulties with attention, categorization, and decision making), unusual beliefs about possessions, and avoidance behaviors.

hoarding is evolutionair gezien opzich logisch!

25
Q

what is the most used medication in ocd

A

anti-depressants

26
Q

what is the most used therapy in ocd

A

exposure-response prevention

27
Q

ERP in ocd

A

OCD: exposure to situations that elicit the compulsive act and then they are supposed to refrain from the compulsive ritual. challenging peoples beliefs about what will happen if they do not engage in these rituals

28
Q

ERP in body dysmorphic disorder

A

exposure to interact with people who could be critical of their looks, response of activities they use to reassure themselves about their appearance

For the treatment of BDD, ERP is supplemented
with cognitive strategies to challenge people’s overly negative views of their appearance, their excessive focus on their appearance, and their belief that self-worth depends on their appearance.

29
Q

ERP in hoarding disorder

A

exposure to disposal of stuff
response prevention focuses on not doing the activities to reduce their anxiety

ERP for hoarding disorder often involves motivational strategies to enhance insight and willingness to consider change.

30
Q

acute stress disorder =

A

when symptoms occur between 3 days and 1 month after trauma

31
Q

what for treatment for treatment resistant ocd

A

Deep transcranial magnetic stimulation (dTMS) and deep brain stimulation (DBS)

32
Q

OCD, BDD, and hoarding disorder are each moderately heritable. There is some shared genetic risk across these three disorders

A

oke

33
Q

welke brain region in het algemeen bij OCD

A

fronto-striatal circuits (rewards!)

34
Q

OCD has been linked to activity in the fronto-striatal circuits, including the orbitofrontal cortex, the caudate nucleus, and the anterior cingulate cortex, during tasks that provoke symptoms.

People with BDD also show hyperactivity in regions of
the orbitofrontal cortex and the caudate nucleus when viewing photos of themselves.

Hoarding disorder involves hyperactivity in the orbitofrontal cortex and the anterior cingulate cortex during symptom-provoking tasks.

A

oke

35
Q

welke region extra bij BDD

A

visual processing regions

36
Q

behavioural model for ocd

A

Tendencies toward repetitive thoughts and behaviors in OCD may be related to a tendency for conditioned responses to become habitual, such that they are sustained even after the threat is removed. Obsessions may be intensified by attempts to suppress unwanted thoughts, in part because people with OCD tend to believe that thinking about something is as bad as doing it, a tendency referred to as thought–action fusion.

37
Q

BDD cognitive model

A

The cognitive model relates BDD to a detail-oriented analytic style and an overvaluing of the importance of appearance to self-worth.

38
Q

antidepressants in BDD and hoarding

little research, geen goed bewijs voor. wel voor ocd.

could stigmatize short-term, normal reactions to trauma. and most people with ptsd do not qualify for ASD within the first month

43
Q

etiology of ptsd

A

2/3 of ppl with ptsd have history of other anxiety disorder

44
Q

two-factor model of conditioning in ptsd

A

coping mechanisms (avoiding = more risk of ptsd, dus dissociation and memory suppression)
