Disruptive/Impulse/Conduct Disorders: Part 1 (General, ODD, IED, Conduct) Flashcards
what is different about the disorders in this chapter
trouble with emotional/behavioural regulation that manifests in behaviours that VIOLATE the rights of others (i.e aggression, destruction of property) and/or that bring the individual into SIGNIFICANT CONFLICT with societal norms or authority figures
what disorder is included in this DSM chapter but is actually described elsewhere
antisocial PD
between CD, IED and ODD, which disorder focuses mostly on poorly controlled behaviours? which focuses mostly on poorly controlled emotions? which disorder is the “middle ground” in which criteria are more evenly distributed between emotions and behaviours?
CD–> behaviours
IED–> emotions
ODD–> more even mix of both
the disruptive/impulse control/conduct disorders generally tend to be more common in which gender
males
when do the disruptive/impulse control/conduct disorders tend to have their onset
childhood or adolescence
–> very rare for ODD or CD to first emerge in adulthood
what is the relationship between CD and ODD
developmental relationship–> most kids who meet criteria for CD would have previously med criteria for ODD (at least in those cases in which CD emerges prior to adolescence)
do most children with ODD go on to develop CD?
no, most do not
are at risk for eventually developing other conditions, like anxiety and depression
the disruptive/impulse control/conduct disorders have been linked to a common spectrum of what personality dimensions
an EXTERNALIZING spectrum with the personality dimensions labeled as DISINHIBITION and CONSTRAINT
and to a lesser extent, negative emotionality
*these shared personality dimensions could account for the high level of comorbidity among these disorders and their frequent comorbidity with SUDs and ASPD
what are the 3 categories of symptoms in criterion A for ODD
angry/irritable mood
argumentative/defiant behaviour
vindictiveness
how many symptoms from the 3 symptom clusters are required to fulfill criterion A for ODD
4+
what are the symptoms listed in the “angry/irritable mood” cluster for criterion A for ODD
- often loses temper
- is often touchy or easily annoyed
- is often angry or resentful
what are the symptoms listed in the “argumentative/defiant behaviour” cluster for criterion A for ODD
- often argues with authority figures or, for kids and teens, with adults
- often actively defies or refuses to comply with requests from authority figures or with rules
- often deliberately annoys others
- often blames others for his or her mistakes or misbehaviour
what are the symptoms listed in the “vindictiveness” cluster for criterion A for ODD
has been spiteful or vindictive at least TWICE in the past 6 months
what is criterion A for ODD
a pattern od angry/irritable mood, argumentative/defiant behaviour, or vindictiveness lasting at least 6 MONTHS as evidenced by at least FOUR symptoms from any of the following categories, and exhibited during interaction with at least ONE individual who is NOT A SIBLING
there are 8 symptoms spread across the three symptom clusters (see other cards)
how do you distinguish a behaviour that is within normal limits from a behaviour that is symptomatic in the case of ODD
the persistence and frequency of the behaviour
kids younger than 5–> behaviour occurs on MOST DAYS for a period of at least 6 months
people aged 5+–> behaviour should occur at least ONCE PER WEEK for at least 6 months
criterion B for ODD
assoc. with distress in the individual or others in his or her immediate context or impacts functioning
criterion C for ODD
not exclusively during course of psychotic, SUD, depressive, bipolar d/o
criteria NOT met for DMDD
how do you determine severity for ODD
number of settings in which symptoms are present
mild–> sx only in 1 setting
moderate–> sx in at least 2 settings
severe–> symptoms in 3+ settings
can you diagnose ODD if sx only occur at home and with family members
yes–> this is not uncommon
but pervasiveness of symptoms is an indicator of the severity of the disorder
how do people with ODD typically view themselves
typically do not regard themselves as angry, oppositional or defiant
often justify their behaviour as a response to unreasonable demands or circumstances
ODD is more common in which type of settings or families
more prevalent in families in which child care is disrupted by a succession of different caregivers
in families in which harsh, inconsistent or neglectful practices are common
what are 2 of the most common co occurring conditions with ODD
ADHD
conduct disorder
how does ODD affect risk of suicide
increases risk of suicide attempts
what is the prevalence of ODD
ranges from 1-11%–> average around 3.3%
(slight male preponderance but overall fairly equal male:female)
when do first sx of ODD usually appear
during preschool years
rarely later in adolescence
ODD conveys risk for development of what other disorders in the future
CD
anxiety
MDD
–> defiant/argumentative + vindictive symptoms = higher risk for CD
–> angry/irritable mood sx = higher risk for emotional disorders
at increased risk of antisocial behaviour, impulse control problems, substance abuse, anxiety and depression as adults
what temperamental factors is felt to be predictive of ODD
problems in emotion regulation–> high levels of emotional reactivity, poor frustration tolerance
list neurobiological markers that have been associated with ODD
lower HR
lower skin conductance reactivity
reduced basal cortisol reactivity
abnormalities in prefrontal cortex and amygdala
*most studies have not separated ODD and CD kids and so its unclear how specific these markers are
ddx ODD
conduct disorder
ADHD
depressive d/o
bipolar d/o
DMDD
IED
intellectual disability
language disorder
social anxiety disorder
how does CD differ from ODD
CD = more intense than ODD, and involves aggression toward people or animals, destruction of property or a pattern of theft or deceit
ODD–> has problems w emotion regulation that are not part of dx of CD
how does IED differ from ODD
in IED, shows SERIOUS aggression towards other unlike in ODD
rates of ODD are much higher in what population
those with ADHD
criterion A for IED
recurrent BEHAVIOURAL OUTBURSTS representing a FAILURE TO CONTROL AGGRESSIVE IMPULSES as manifested by either:
1. VERBAL AGGRESSION (temper tantrums, tirades, verbal arguments, or fights) or PHYSICAL AGGRESSION towards property, animals or other individuals, occurring TWICE WEEKLY on average for a period of THREE MONTHS. Physical aggression does not result in damage or destruction of property and does not result in physical injury to animals or other individuals
or
2. THREE behavioural outbursts involving DAMAGE or destruction of property and/or physical assault involving physical injury against animals or other individuals occurring within a 12 MONTH period
criterion B for IED
MAGNITUDE of the aggressiveness expressed during the recurrent outbursts is grossly OUT OF PROPORTION to the provocation or to any precipitating psychosocial stressors
criterion C IED
recurrent outbursts are NOT PREMEDITATED (are impulsive or anger based) and are not committed to achieve some tangible objective (i.e money, power, intimidation)
criterion D IED
recurrent oubursts cause either marked distress in the person or impairment in occupational or interpersonal functioning or have financial or legal consequences
what is the minimum age for diagnosis of IED
chronological age is at least 6 years old (or equivalent developmental level)
how quickly do the outbursts in IED arise, and how long do they typically last
rapid onset
typically little or no prodromal period
typically last for less than 30 min
commonly occur in response to a minor provocation by a close intimate associate
can you have both DMDD and IED
no
what is the one year prevalence of IED in the USA
about 2.7%
in which populations is IED more common
younger (below 35-40 years)
those with high school education or less
when does IED usually have its onset
most common in late childhood or adolescence
rarely begins after age 40
what is the typical course of IED
typically persistent and continue for many years
may be episodic
appears to follow chronic and persistent course over many years
what is an environmental risk factor for IED
ppl with hx physical and emotional trauma during FIRST TWO DECADES of life are at higher risk for IED
is there a genetic vulnerability to IED
yes–> first degree relatives of those with IED are at increased risk of having it themselves
twin studies–> “substantial genetic influence for impulsive aggression”
what types of neurological abnormalities are seen in those with IED
serotonergic abnormalities both globally and in the brain–> specifically in limbic system (anterior cingulate) and orbitofrontal cortex
per fMRI, amygdala responses to anger stimuli are higher in those with IED
ddx IED
DMDD
ASPD or BPD
delirium
major NCD
personality change due to another medical condition, aggressive type
substance intox or withdrawal
ADHD
CD
ODD
autism spectrum disorder
how does the level of impulsive aggression compare between ASPD and IED
higher in IED
