SD, acute stress disorder, borderline personality disorder,somatic symptom disorder,
substance use disorder, CiMC (various neurologic disorders including complex/partialseizures,
migraine, Cotard syndrome)
Dissociative Identity Disorder
• disruption of identity characterized by >2 distinct personality states or an experience of possession
• can manifest assudden alterations in sense ofself and agency (ego-dystonic emotions, behaviours,
speech)
« features recurrent episodes of amnesia (declarative or procedural) as well as episodes of
depersonalization and derealization
• rare (<1%); can manifest at any age, although childhood physical/sexual abuse or neglect are a major
risk factor
• caution: high-risk of attempting suicide and/or self-harm
• DDx includes borderline personality disorder and PTSD
Dissociative Amnesia
• inability to recall important autobiographical information, usually of a traumatic or stressful nature,
that is inconsistent with normal forgetting and not attributable lo a psychiatric disorder, a medical
illness, or effects of a substance
• localized/selective amnesia: failure to recall all/some events during a prescribed period of time
(however procedural memory is preserved)
• can experience periods of flashbacks or nightmares related to associated trauma, increased risk of
suicide as amnesia resolves
• generalized amnesia (more rare): complete loss of memory for one’slife history, ± procedural
knowledge, ± semantic knowledge; usually sudden onset; often presents with perplexity,
disorientation, and aimless wandering
Dissociative Fugue
Sudden unexpected travel away from
home that Is accompanied by amnesia
for identity or other autobiographical
details
Depersonalization/Derealization Disorder
• persistent or recurrent episodes of one or both of:
depersonalization: experiences of detachment from oneself,feelings of unreality,or a sense of
being an outside observer to one’
sthoughts, feelings,speech, and actions (can feature distortions
in perception including time, as well as emotional and physical numbing)
derealization: experiences of unreality or detachment with respect to the surroundings(i.e.
feeling as if in a dream,or that the world is not real; external visual world is foggy or distorted)
• transient (s-h) experiences of this nature are quite common in the general population
• episodes can range from h-yr; patients are often quite distressed and verbalize concerns of "
going
crazy"
During depersonalization (detachment
from one'sself) or derealization
(detachment from one'ssurroundings),
patients usually have intact reality
testing, which adds to their alarming
nature

Sleep Disorders
•for more information regarding normal sleep cycles and the illnesses described,see
Disorders, N48
Overview
•adequate sleep is essential to normal functioning; deprivation can lead to cognitive impairment and
increased mortality
•circadian rhythms help regulate mood and cognitive performance
•neurotransmitters commonly implicated in psychiatric illnesses also regulate sleep
• increased ACh activity and decreased activity of monoamine neurotransmitters are associated
with greater REM sleep
decreased adrenergic and cholinergic activity are associated with NKEM sleep
•depression is associated with decreased A (deep,slow-wave) sleep, decreased REM latency, and
increased REM density
•criteria for sleep disorders:
must cause significant distress or impairment in normal functioning
not due to a General Medical Condition (GMC) or medications/drugs(unlessspecified)
Management
•sleep hygiene is a simple, effective, but often underutilized method for addressing sleep disturbances;
recommendations include:
waking up and going to bed at same time every day, including on weekends
avoiding long periods of wakefulness in bed
not using bed for non-sleep activities (reading, TV, work)
avoiding screens, especially smartphones and iPads in the hour before bed
avoiding napping
discontinuing or reducing consumption of alcohol, caffeine, drugs
• exercising at least 3-4 X /WK (but not in the evening if this interferes with sleep)
•cognitive behavioural therapy for insomnia (CBTi) is considered first
-line treatment for chronic
insomnia
•pharmacological treatments are illness-specific
avoid benzodiazepines:increased risk of abuse/dependence, rebound anxiety/insomnia, cognitive
impairment,daytime somnolence, and disturbed sleep architecture (suppresses deep and REM
sleep)
non-benzodiazepines (c.g. zopiclone/eszopiclone/zolpidem, lemborexant, low dose doxepin) are
preferred and effective for short
-term treatment; they should be re-evaluated regularly aslongterm use is associated with dependency
• “z-drugs": common side-effect is bitter metallic taste, which is improved by something acidic such
as orange juice; high doses increase risk of cognitive impairment and falls (particularly among
the elderly)
lemborexant (orexin receptor antagonist) reduces wake pressure/drive, as opposed to increasing
sleep pressure/drive with other sedating agents; avoid use in patients with narcolepsy or cataplexy
trazodone,mirtazapine, and quetiapine can be prescribed off-label if there are comorbid
psychiatric symptoms
low-dose amitriptyline can be prescribed for patients with comorbid pain
screen for complex sleep behaviours before and after prescribing a medication for insomnia
consider whether sleep issue is part of another psychiatric or medical illness and treat those
conditions

Eating Disorders s
Definition
• eating disorders are characterized by a persistent disturbance of eating that impairs psychosocial
functioning or health
• disorders include: anorexia nervosa, avoidant/restrictive food intake disorder, binge eating disorder,
bulimia nervosa, pica, and rumination disorder
Eating Disorder Screening
Method to identity patients with
eating disorders. A "Yes" to two or
more questions is associated with a
sensitivity and specificity of 78 and 88%.
respectively
Epidemiology
• anorexia nervosa (AN): 1% of adolescent and young adult females; 0.3% males; onset in mid-teens
(14-18 yr)
• bulimia nervosa (BN ): 2-4% of adolescent and young adult females;0.5% males;onset in late teens or
early adulthood
• I
:
:M= I 0: I; mortality of AN 5- 10"
,,
t common comorhidities:depression (50-75%),substance misuse (35% in BN, 15% in AN ), OCD (25% in
AN )
SCOFF
Do you make yourself Sick because you
feel uncomfortably full?
Do you worry you have lost Control over
how much you eat?
Have you recently lost more than One
stone (M pounds or 6.35 kg) in a 3 mo
period?
Do you believe yourself to be Fat when
otherssay you are too thin?
Would you say that Food dominates
your life?
Etiology
• multifactorial: psychological,sociological, and biological associations
• individual: perfectionism, lack of control in other life areas, history of sexual abuse
• personality: anxiety, perfectionism, obsessionality, negative emotionality, cognitive inflexibility
• family & sociocultural:invalidating family structure, prevalent in industrialized societies,
idealization of thinness in the media,athletic demands
• puberty
• genetic factors
AN:6% prevalence in siblings,with one study of twin pairs finding concordance in 9 of 12
monozygotic pairs vs.concordance in 1 of 14 dizygotic pairs (lOx greater risk among first-degree
relatives)
BN:higher familial incidence of affective disorders than the general population
Risk Factors
• physical factors:obesity, chronic medical illness (e.g. DM)
• psychological factors:individuals who by career choice are expected to be thin,family history'
(mood disorders,eating disorders,substance use disorder), history ofsexual abuse (especially for
BN), competitive athletes, concurrent associated mental illness (depression, OCD, anxiety disorder
(especially panic and agoraphobia),substance use disorder (specifically for BN))
Complications
• growth delay, osteoporosis(40%), osteopenia (50%), cardiovascular complications (bradycardia,
QTc prolongation,starvation edema), gastrointestinal complications (irritable bowel syndrome,
constipation,gastric dilation), electrolyte disturbances(hypokalemia, hypomagnesemia,
hypophosphatemia), refeeding syndrome, and endocrine abnormalities (increased GH, reduced LH,
1'
SH, and T3)
Anorexia Nervosa
DSM-5 DIAGNOSTIC CRITERIA FOR ANOREXIA NERVOSA
Repiinled with permission from the Diagnostic and Slatislical Manual olMental Disorders, 5th cd. 2013. American Psychiatric Association
A.restriction of energy intake relative to requirements, leading to a significantly low body weight in
the context of age,sex, developmental trajectory, and physical health. Significantly low weight is
defined as a weight that isless than minimally normal or, for children and adolescents, less than that
minimally expected
B.intense fear of gaining weight or of becoming fat, or persistent behaviour that interferes with weight
gain, even though at a significantly low weight
C.disturbance in the way in which one'
s body weight orshape is experienced, undue influence of body
weight or shape on self-evaluation,or persistent lack of recognition of the seriousness of the current
low body weight
• specifiers: partial remission, full remission,severity based on BM1 (mild = BMI >17 kg/m -, moderate
= BMI 16-16.99 kg/m2 ,severe = BMI 15-15.99 kg/m5 extreme = BMI <15 kg/m2), type (restricting =
during last 3 mo no episodes of binge-eating or purging vs. binge-eating/purging type = in last 3 mo
have participated in recurrent episodes of binge-eating/purging)
Athletic Triad
Disordered eating
Amenorrhea
Osteoporosis
Some patients with insulin-dependent
DM may stop their insulin in order to
lose weight
r-t
Management
• standard svork-up:vitals (weight and orthostatic BP and HR), Woodwork (CBC, electrolytes,
creatinine, liver enzymes,B12,TSH), KCG
• psychotherapy:individual,group,family; address food and body perception, coping mechanisms,
health effects
• CBT:sets clear weight goals and expectations, makes use of recording sheets, targets maintaining
factorssuch as negative body image
• family-based treatment is primarily used in the paediatric system, main focus is on weight restoration
and return to physical health

PSIO Psychiatry Toronto Notes 2023
•medications of little value;however,SSRls may be helpful in treating concurrent mood and anxiety
disorders
•outpatient and inpatient programs are available (nutritional rehabilitation)
•inpatient psychiatric hospitalization for treatment of eating disorders is rarely on an acute basis
(unless there is a concurrent psychiatric reason for emergent admission (e.g. suicide risk));such
patients often require a specialized LD program
•criteria to admit to medical ward for hospitalization: <65% ofstandard body weight (<85% of standard
body weight for adolescents), hypovolemia requiring intravenousfluid, heart rate <40 bpm, abnormal
serum chemistry (e.g.low K+ , low Mg2+, Low PO43-, high creatinine),or if actively suicidal
•agree on target body weight on admission and reassure this weight will not be surpassed
•monitor for complications of AN (see Table 9, PS41)
•monitor for refeeding syndrome
• potentially life-threatening metabolic response to refeeding in severely malnourished patients
resulting in severe shifts in fluid and electrolyte levels
complications include hypophosphatemia, congestive heart failure, cardiac arrhythmias,
delirium, and death
prevention:slow refeeding,gradual increase in nutrition,supplemental phosphorus, and close
monitoring of electrolytes and cardiac status
Prognosis
•adolescent onset has much better prognosis than adult onset
•only about 50% make a full recovery
•witn treatment, 70% resume a weight of at least 85% of expected levels and about 57% resume normal
menstrual function
•eating peculiarities and associated psychiatric symptoms are common and persistent
•high rates of mortality (7%) secondary to severe and chronic starvation, metabolic or cardiac
catastrophes,with a significant proportion dying by suicide
Bulimia Nervosa
DSM-5 DIAGNOSTIC CRITERIA FOR BULIMIA NERVOSA
Reprinted withpermission from the Diagnostic and Statistical Manual of Mental Disorders.Sth ed.2013. American Psychiatric Association
A.recurrent episodes of binge-eating; an episode of binge-eating is characterized by both of the
following:
eating, in a discrete period of time, an amount of food that is definitely larger than what most
individuals would eat during a similar period of time and under similar circumstances
• a sense of lack of control over eating during the episode
B.recurrent inappropriate compensatory behaviour in order to prevent weight gain,such asself-induced
vomiting, misuse of laxatives, diuretics, enemas, or other medications, fasting, or excessive exercise
C.the binge-eating and inappropriate compensatory behaviours both occur, on average, at least once a
week for 3 mo
D.self-evaluation is unduly influenced by body shape and weight
E.the disturbance does not occur exclusively during episodes of AN
• specifiers: partial remission, full remission,severity (mild = 1-3 inappropriate compensatory
behaviours/wk, moderate = 4-7 inappropriate compensatory behaviours/wk,severe
= 8-13
inappropriate compensatory behaviours/wk, extreme = 14+ inappropriate compensatory behaviours/
wk)
Associated Features
- fatigue and muscle weakness due to repetitive vomiting and fluid/electrolyte imbalance
• tooth decay, perioral irritation, mouth ulcers
• swollen appearance around angle of jaw and puffiness of eye sockets due to fluid retention, edema
• reddened knuckles, Russell’ssign (knuckle callus from self-induced vomiting)
• trouble concentrating,fatigue, headache, abdominal pain/reflux
• weight fluctuation over time
Management
• medical admission forsignificant electrolyte abnormalities
• biological: treatment ofstarvation effects,SSRls (60 mg fluoxetine has the most evidence) as adjunct
• psychological: develop trusting relationship with therapist to explore personal etiology and triggers,
CBT,family therapy, recognition of health risks
• social: challenge destructive societal views of women, use of hospital environment to provide external
patterning for normative eating behaviour
Prognosis
• relapsing/remitting disease
• good prognostic factors:onset before age 15,achieving a healthy weight within 2 yr of treatment
• poor prognostic factors:later age of onset, previous hospitalizations, individual and familial
disturbance
• 60% good treatment outcome, 30% intermediate outcome, 10% poor outcome (mortality rate of
approximately 2% per decade)

Binge-Eating Disorder
Definition
• recurrent episodes of hinge-eating (as defined by criteria A of BN ) that are associated with eating
much more rapidly than normal, eating until feeling uncomfortably full, eating large amounts when
not physically hungry, eating alone because embarrassed by how much one is eating, and/or feeling
disgusted with oneself/depressed/very guilty afterwards at least once/wk x 3 mo
• not associated with any compensatory behaviours
• dieting usually follows binge-eating (vs. BN where dysfunctional dieting typically precedes bingeeating)
• for more details about Binge- hating Disorder, please consult the DSM-5
Points for Differentiating Between
Eating Disorders
• AN of binge-eating/purging type
(significantly low body weight) takes
priority over a BN diagnosis (body
weight not in criteria)
• BN requires compensatory
behaviours
• Binge-eating disorder does not
involve compensatory behaviours
• Avoidant/restrictive food intake
disorder does not involve
disturbances in body image
Epidemiology
• F:M«2:1
• begins in adolescence or young adulthood
Treatment
• CUT
Avoidant/Restrictive Food Intake Disorder
Definition
• eating/feeding disturbance (i.e. apparent lack of interest in eating or food ) to the extent of persistent
failure to meet appropriate nutritional and/or energy needs, resulting in significant weight loss/
growth failure and nutritional deficiencies; patients experience disturbances in psychosocial
functioning and may become dependent on enteral feeding/oral nutritional supplementation
does not occur during an episode of AN or BN and not better explained by lack of available food
or culturally sanctioned practice
no evidence of distress in the way in which one’s body weight or shape is experienced
Risk Factors
• temperament (e.g. anxiety disorders), environment (e.g.familial anxiety), genetic (e.g.history of GI
conditions)
• begins in infancy and can persist into adulthood
Treatment
• psychoeducation
• behaviour modification
• psychotherapy

Personality Disorders
•in the literature, personality and its disorders can be understood using a trait-based dimensional
approach (i.e. 5 major traits such as extraversion, agreeableness, conscientiousness, neuroticism,
and openness to experiences rated on a continuum of dysfunctional effects), rather than discrete
categories; however, the discrete categories still remain in the current DSM and will be referenced here
General Information
•an enduring pattern of inner experience and behaviour that deviates markedly from the expectations
of the individual’s culture; manifested in two or more of:cognition, affect, interpersonal functioning,
impulse control
•inflexible and pervasive across a range of situations
•pattern isstable and well-established by adolescence or early adulthood (i.e. not a sudden onset)
•associated with many comorhiditiessuch as depression,suicide, violence, brief psychotic episodes,
substance use, and treatment resistance
•relationship building and establishing boundaries are important; focus should be placed on
validating, finding things to be truly cmpathetic about, and speaking to the patient'
s strengths
•mainstay of treatment is psychotherapy (e.g. CUT, interpersonal psychotherapy, psychodynamic
psychotherapy, DBT); add pharmacotherapy to treat associated psychiatric disorders (e.g. depression,
anxiety,substance misuse)
Classification
•personality disorders are divided into three clusters (A, B, and C), with shared features among
disorders within each
A flag for personality disorders in clinical

Child Psychiatry
Developmental Concepts
• temperament: a child '
s innate psycho-physiological and behavioural characteristics (i.e. emotionality,
activity, and sociability);spectrum from “difficult" to “slow-to-warm-up" to “easy temperament”
• parental fit: the congruence between parenting style (authoritative, permissive) and child’s
temperament
• attachment:special relationship between child and primary caretaker(s);develops during first year,
the caretaker’s attachment style isthe best predictor of their child’s attachmentstyle,see Table 12
• separation anxiety (normal between 10-18 mo): where separation from attachment figure results in
distress
Consider speaking to children alone.
Always consider child abuse in your ODx.
See Paediatrics. P18
Tips
Q
for the Child Interview
• Use language the child will
understand (e.g. don't ask about
feelings of worthlessness,ask about
whether they feel like they are a
bad kid)
• Use developmentally-appropriate
questions (e.g. don't ask about lack
of interest in activities, ask children
whether they feel bored)

Prognosis
« prolonged episodes, up to 1-2 yr = poor prognosis
• prognosis variable; adolescents with depression more likely to have depression in adulthood than
adolescents without
• approximately 2% of adolescents with depression will develop bipolar disorder within 4 yr
• complications: negative impact on family and peer relationships,school failure,significantly increased
risk of suicide attempt or completion (however,suicide risk low for pre-pubertal children),substance
use disorder
DISRUPTIVE MOOD DYSREGULATION DISORDER
Clinical Features
• severe, developmental^
inappropriate,recurrent verbal or behavioural temper outbursts at least 3x/
wk with persistently irritable mood in between
• symptom onset before age 10, occurring for 212 mo, in 22 settings, with no more than 3 consecutive
mo free from symptoms
• diagnosisshould be made between ages 6-18
• criteria not met for intermittent explosive disorder nor bipolar disorder ( no mania/hypomania)
• supersedes diagnosis of ODD if criteria for both are met
• common comorbidities: ADHD, anxiety'disorders, depressive disorders
BIPOLAR DISORDER
Clinical Features
• mixed presentation and psychotic symptoms ( hallucinations and delusions) more common in
adolescent population than adult population
often misdiagnosed in the adolescent population
• unipolar depression may be an early sign of adult bipolar disorder
• associated with rapid onset of depression, psychomotor retardation, mood-congruent psychosis,
affective illness in family, and pharmacologically-induced mania
Attachment type can be assessed
ininfants 10-18 mo of age using the
Grange Situation test,in which the
child is stressed by the caregiver being
removed from the situation and the
stranger staying. Attachment style is
measured by the child's behaviour
during the reunion with the caregiver
Treatment
• lack of research in adolescent population, treatment guidelines based off of adult recommendations
• pharmacotherapy: mood stabilizers (lithium, anticonvulsants) and/or antipsychotics (risperidone,
olanzapine, quetiapine, aripiprazole)
• psychotherapy:CBT, family-focused therapy (a therapeutic modality designed for bipolar disorder
that combines psychoeducation, communication skills training, and problem-solving skills training)

Differential Diagnosis
•depressive disorders,ODD, truancy
•persistence and impairment to daily functioning differentiates anxiety disorder from normal anxiety
•for school avoidance, differentiate social anxiety (fear of performance and humiliation) from
generalized anxiety
•consider anxiety about separation, and rule out bullying and school refusal due to learning disorder
Course and Prognosis
•better prognosis with later age of onset, fewer comorbidities, early initiation of treatment, ability to
maintain school attendance and peer relationships, and absence of social anxiety disorder
•with treatment, up to 80% of children will not meet criteria for their anxiety disorder at 3 yr followup, but up to 30% will meet criteria for another psychiatric disorder
Treatment
•similar principles for most childhood anxiety disorders due to overlapping symptomatology and
frequent comorbidity
•psychoeducation of child and family
•psychotherapy: CBT has been shown to be effective in children and adolescents with anxiety
•pharmacotherapy: SSRls can be helpful
The shy child is quiet and reluctant to
participate but slowly ‘warms up'

SOCIAL ANXIETY DISORDER (SOCIAL PHOBIA)
• anxiety, fear, and/or avoidance provoked by situations where child feels under the scrutiny of others
• must distinguish between shy child, child with issues functioning socially (e.g. autism), and child with
social anxiety
diagnosis only if anxiety interferessignificantly with daily routine,social life, academic
functioning, or if markedly distressed. Must occur in settings with peers, not just adults
