412 post-M2 Flashcards
hypomanic episode
- same symptom criteria as a manic episode
- lasting at least 4 days
- represents a change in functioning, but no marked impairment in social or occupational functioning
manic episode
- A distinct period of abnormally and persistently elevated, expansive, or irritable mood, lasting at least ONE WEEK (or any duration if hospitalization is necessary)
- Three or more (four if mood is only irritable) are present to a significant degree:
- inflated self-esteem or grandiosity
- decreased need for sleep
- more talkative than usual or pressure to keep talking
- flight of ideas or subjective experience of racing thoughts
- distractibility
- increase in goal-directed activity or psychomotor agitation
- excessive involvement in pleasurable activities that have a high potential for painful consequences
Bipolar I
- presence of a manic episode, regardless of whether depressive episodes have been present
- may show mixed features: concurrent depressive and manic symptoms
Bipolar II
- major depressive episode AND hypomanic episodes
- has never had a full manic episode
cyclothymia
- period lasting at least 1 year (2 in adults) of manic symptoms that do not meet feel criteria for either a manic or hypomanic episode and depressive symptoms that do not meet criteria for MDD
bipolar in children
- diagnoses of BP quadrupled between 1990-2000, exacerbated by the publication of a book arguing that BP in kids was being overlooked
- in 2001, it was decided that BP could be diagnosed in kids but that there could be presentation differences
- adults typically have discrete episodes, but kids could be cycling through moods rapidly (within the same day) which could last for long periods of time (1-4 years)
narrow phenotype BP
- ‘classic’ adult symptoms of grandiosity and mania
- some children do meet full adult criteria
- maybe we’re missing the kids who have BP but present differently
broad phenotype BP
- including irritability, mood swings
- irritability is common in typical kids and in many other disorders (depression, ODD)
- argued that we’re losing specificity and maybe this isn’t bipolar at all
diagnostic challenges for BP
- irritability rather than euphoria can be the main mood state which requires many DDx (depression, ODD, CD, ADHD)
- arguing for a more narrow phenotype in which core symptoms of mania must be present
- but decision that criteria for adults should be applied to children too (irritability should still be a marked change in state)
- children may not show discrete episodes of mood changes
- diagnostic validity of BP in kids is unclear (concerns about overdiagnosis - frequent temper tantrums and chronic irritability), so creation of DMDD diagnosis
prevalence and course of BP
- BP very rare prior to puberty, then rates rise in adolescence
- lifetime prevalence of BP1, 2 is 2.9%
- 60% of people report their first episode in adolescence (before age 19), and the first episode tends to be MDD
- there may be subclinical mania or depression prior to first episode, which is difficult to identify
- mania in adolescence is associated with psychosis, mixed episodes (more severe course)
recovery for BP
- recovery: 2 months without meeting DSM criteria for manic, hypomanic, depressive, mixed episode
- 40-100% of children/teens will recover within their first year, but 60-70% of them will show recurrence (another episode)
- recovery rates are dependent on age of onset
- prepubertal onset is associated with much lower rates of recovery than onset during puberty
- childhood mania is an important risk factor for adult mania (more severe and chronic) - homotypic continuity
comorbidity bipolar
- ADHD: 60-90% of children, 30% of teens (stimulant medication can exacerbate bipolar symptoms)
- disruptive bx disorders: 20% of kids meet criteria for conduct disorder (could be symptom overlap or that the disruptive behaviours are a product of your bipolar presentation)
clinical correlates of bipolar
- marked social impairment
- peer problems: social skill deficits, teased and victimized by peers, few friends
- families: poor relationships with siblings, hostility and conflict with parents
etiological factors in BP
- highly heritable (estimates over 75%, high concordance rates in Mz twins), but not completely genetically based (environmental factors still play a role)
- genetics play a larger role in early onset cases (severe and chronic cases)
- multiple gene problem
- diathesis-stress model with exposure to stress
- stressor can be problematic family interactions (hostility, conflict) = passive gene-environment correlation
treatment of BP
- medication: mood stabilizers (lithium), antipsychotics, antidepressants
- pharmacotherapy is indicated for treatment of all youth with BP (thought many do not receive it or receive the wrong medication like antidepressants on their own)
- psychosocial: family education
lithium treatment for BP
- commonly used in adults, approved for kids aged 12+
- has serious side effects and can be toxic if dosage is wrong (renal problems, hyperthyroidism)
- compliance and monitoring are very important
- meta-analysis showed safety in short-term, some small side-effects WHEN compliance and monitoring were good
atypical antipsychotics for BP
- wide-ranging class (many different options to try)
- ten RCTs have demonstrated good efficacy for BP in youth
antidepressants for BP
- depressive episodes can be chronic and severe, but antipsychotics/mood stabilizers only help with manic symptoms
- using antidepressants alone can exacerbate/provoke manic episodes in people with BP (bipolar switch)
- rarely prescribed alone; best to prescribe in conjunction with lithium or antipsychotics
recommendations for youth with BP
- begin with one atypical antipsychotic, if they don’t respond or cannot tolerate it, try a different one
- if a patient isn’t responding to 2-3 antipsychotics, switch to lithium
- if a patient partially responds to the antipsychotic, add lithium
- see about adding antidepressants afterwards
psychosocial treatment for BP
- family education: understanding the disorder and symptoms, reducing conflict in the family, medication management
- multifamily psycheducational psychotherapy and family-focused therapy both emphasizing education, communication, problem-solving skills showed similar efficacy in improving mood symptoms
RAINBOW in child- and family-focused CBT (CFF-CBT)
- Routine: establish a predictable routine to reduce tantrums, negativity, conflict
- Affect regulation: understanding triggers and helping parents and kids manage episodes
- I can do it: increase beliefs that kids and parents can manage symptoms
- No negative thoughts: retraining cognitive distortions associated with depression
- Be a good friend and Balanced lifestyle
- Oh, how can we solve this problem: improving problem-solving skills in parents and kids
- Ways to get support: help parents learn to access support and advocate for their child at school
CFF-CBT for pediatric BP trial
- kids aged 7-13 diagnosed with BP who were treated with medication (stabilized, no acute symptoms)
- assigned to treatment as usual or CFF-CBT
- outcome measures: parent and clinician report of mania and depression
- after treatment, youth in CBT had lower mania symptoms (below the clinical cutoff)
- youth in CBT had lower depressive symptoms according to parent report, but not according to clinician report
- psychosocial therapy can further reduce symptoms for patients stabilized on medication
definition of child maltreatment
- any recent act or failure to act on the part of a parent or caretaker, which results in death, serious physical or emotional harm, sexual abuse, or exploitation, or an act or failure to act, which presents an imminent risk of serious harm
- includes physical/emotional/sexual abuse, physical/educational/emotional neglect
physical abuse
- punching, beating, kicking, burning, shaking, or otherwise physically harming a child
- often unintentional and resulting from severe physical punishment
neglect
- child’s basic needs aren’t being met
- physical: refusal of healthcare, inadequate supervision, lack of food
- emotional: not attending to emotional needs, not providing psychological care when required
- educational: not putting the child in school, not attending to special education needs or accommodation
sexual abuse
- touching genitals, intercourse, exhibitionism, production of pornographic photos
emotional abuse
- repeated acts by parents/caregivers that could/have caused serious behavioural, cognitive, emotional or mental disorders
epidemiology of child maltreatment
- difficult to study incidence and prevalence due to people not reporting (parents unwilling, kids unable/unaware), using retrospective report
- rates will depend on how you operationalize abuse and maltreatment
- US has slightly higher rates than Canada, likely due to higher rates of poverty + difficult to access health care
- most commonly reported experience is neglect, then physical, then sexual, then emotional abuse (studies still mostly focus on physical/sexual abuse)
demographic characteristics of child maltreatment
- age: younger kids more likely to be neglected, older (12+) more likely to be sexually abused
- gender: girls more likely to be sexually abused
- single-parent families have higher rates of physical abuse and neglect
- poverty is a risk factor
- more upward social mobility = less rate of maltreatment (ease of access to education and resources = moving out of lower classes, so the stress of a lack of resources could be a risk factor for maltreatment)
Covid and child maltreatment
- rates increased across the globe during lockdowns
- most notable increases in low and middle income countries (LMIC)
- poverty is a risk factor in individual families and nationwide (compounding risk factors)
- chronosystem influence on prevalence of maltreatment and subsequent psychopathology
developmental course of maltreatment
- kids must learn to cope with challenges in environment which may be adaptive in maltreatment situations, but could become maladaptive in other situations
- maltreatment shapes brain development (smaller brain volumes), physiological reactivity to stress (strong spikes or blunted responses), understanding of emotion
maltreatment and understanding of emotion
- maltreatment = exposed to different emotional experiences = changing your understanding and experience of emotion (hypervigilance to anger signs)
emotion recognition task maltreatment study
- included physically abused or neglected kids compared to no abuse history between 3-5 years
- kids presented with vignettes of stories representing happiness, sadness, fear, disgust, anger and told to point to the correct facial expression for that story
- evaluating sensitivity to differences between expressions (are kids correct in their choices), bias toward choosing a certain emotion (are they always choosing an emotion)
- neglected kids are less sensitive (not good at differentiating)
- physically abused kids show a bias for angry faces, neglected kids show a bias for sad faces
- could be due to a visual inability to discriminate between faces or these kids have different understandings of the emotional displays
