Slide 2









Review an approach to diagnosis of Depressive
Disorders

Examine the clinical course of MDD
Consider the rationale behind the drive to
achieve remission
Evidence-based selection of treatment options


Slide 3

“ Depression”


Slide 4

“Doctor, I am depressed”
because...
 My lotto numbers did not “drop” this
week
 My wife left me last week
 My husband died three years ago
 There is no reason for me to feel this
way


Slide 5

 Diagnosis

and treatment of
“depression”
depended on the clinician’s
perspective


Slide 6

 Psychological
 biological

- nurture

- nature


Slide 7







Causation -life events, “stressors”
Diagnosis – Reactive depression,
Neurotic depression
Treatment - psychotherapy “tell me
about your mother.... Your finances,
your husband, boss


Slide 8







One man’s stress, is another man’s pleasure

“If I look hard enough, I will find stress”
e.g. travelling to Ghana, jet lag, preparing
for a presentation, carrying back kobe


Slide 9





Diagnosis – Endogenous depression

Treatment - Biological –medication,
ECT


Slide 10







No one would consider putting someone on
an antidepressant because of a lotto ticket

What about the man who has lost 30 pounds,
cannot sleep, has been thinking of suicide for
the past two months, because of the lotto
ticket?
And on what basis would one decide which
treatment?


Slide 11

 Somewhere

in between


Slide 12







Symptoms clusters that responded biological
interventions
Mood disturbance that seemed to be
autonomous, impairment in in parametres
such as sleep, energy, appetite, concentration
Precipitants/stressors – not relevant to the
diagnosis of MDD (except bereavement)


Slide 13

 A. At least Five

of the following

symptoms
 present during the same 2-week
period
 represent a change from previous
functioning


Slide 14



Of five at least one of the symptoms is
EITHER

(1) depressed mood most of the day, nearly
every day, either subjective report (e.g., feels
sad or empty) or observation by others (e.g.,
appears tearful). In children and adolescents,
can be irritable mood.
OR
(2) markedly diminished interest or pleasure in
all, or almost all, activities most of the day,
nearly every day .


Slide 15

(3) significant weight loss when not dieting
or weight gain (e.g., a change of more than
5% of body weight in a month), or decrease
or increase in appetite nearly every day.
Note: In children, consider failure to make
expected weight gains.
(4) insomnia or hypersomnia nearly every
day


Slide 16

(5) psychomotor agitation or retardation
nearly every day (observable by others, not
merely subjective feelings of restlessness or
being slowed down)
(6) fatigue or loss of energy nearly every
day


Slide 17



(7) feelings of worthlessness or excessive or
inappropriate guilt (which may be delusional) nearly
every day (not merely self-reproach or guilt about
being sick)
(8) diminished ability to think or concentrate, or
indecisiveness, nearly every day (either by subjective
account or as observed by others)
(9) recurrent thoughts of death (not just fear of
dying), recurrent suicidal ideation without a specific
plan, or a specific plan for committing suicide or a
suicide attempt


Slide 18

 B. The symptoms do not meet criteria for a

Mixed Episode.

C. The symptoms cause clinically significant

distress or impairment in social, occupational,
or other important areas of functioning.

D. The symptoms are not due to the direct
physiological effects of a substance (e.g., a
drug of abuse, a medication) or a general
medical condition (e.g., hypothyroidism).


Slide 19



E. The symptoms are not better accounted

for by Bereavement, i.e., after the loss of a
loved one, the symptoms persist for longer
than 2 months or are characterized by
marked functional impairment, morbid
preoccupation with worthlessness, suicidal
ideation, psychotic symptoms, or
psychomotor retardation.


Slide 20



Major depressive disorder

◦ Major depressive disorder, single episode
◦ Major depressive disorder, recurrent - (two or

more episodes)





Dysthymic disorder
Depressive Disorder NOS
(Adjustment Disorder – depressed mood)


Slide 21



Major depressive disorder
◦ Major depressive disorder, single episode
◦ Major depressive disorder, recurrent - (two or

more episodes)


Slide 22

Mild
 Moderate
 Severe without psychotic features
 Severe with psychotic features
 In partial remission
 In remission



Slide 23





Melancholic depression - loss of pleasure in most or all
activities,, a quality of depressed mood more pronounced
than that of grief or loss,
a worsening of symptoms in the morning hours, earlymorning waking, psychomotor retardation, excessive weight
loss, excessive guilt.
Atypical depression - mood reactivity (paradoxical
anhedonia) and positivity, significant weight gain or increased
appetite (comfort eating), hypersomnia ,), a sensation of
heaviness in limbs known as leaden paralysis, and significant
social impairment as a consequence of rejection
hypersensitivity


Slide 24



Catatonic depression - rare and severe form of major
depression involving disturbances of motor behavior and
other symptoms. Patient is mute and almost stuporous,
immobile or engages in purposeless or even bizarre
movements.
Rule out schizophrenia /neuroleptic malignant syndrome .





Post partum depression -10–15% among new mothers onset
occur within one month of delivery
Seasonal affective Disorder (SAD) – onset fall/autumn
subsides following spring ,at least two episodes have
occurred in colder months with none at other times, over at
least a two-year period


Slide 25











Normal bereavement – 2 months
Bipolar depression - previous (hypomanic)
episode
DYTHYMIC DISORDER Chronic “Low grade” 2
years
Adjustment Disorder- depressed mood
Other mental disorders e.g. schizoaffective
Substance induced
Medical – e.g. Hypothyroidism,


Slide 26








$15 billion / yr (USA)
2030 - second leading cause of disability
(WHO) after HIV
Morbidity – presenteeism, absenteeism,
relationship, occupational, obesity, diabetes,
cancers
Comorbidity ( worse prognosis)– anxiety
disorders, substance use disorders,
personality disorders,


Slide 27

Mortality - lifetime risk of suicide in the US
estimated at “3.4%”,
Men -almost 7%
Women- 1%
The estimate is substantially lower than a
previously accepted figure of 15%, which had
been derived from older studies of
hospitalized patients -15%




Slide 28





Mortality – lifetime risk of suicide in
untreated major depressive disorder 20%
Less than 25% of those with MDD adequately
treated


Slide 29




smoking and obesity -increased likelihood
cardiovascular disease
-1.5- to 2-fold increased risk, independent of
other known risk factors






colorectal cancer
- Up to 43% greater risk in depressed women
- "dose-response" relationship observed
- overweight women had highest


Slide 30

Higher incidence in medical conditions
 e.g. obesity, chronic pain , diabetes
neurological conditions such as strokes,
Parkinson's disease, MS


Slide 31

Lifetime prevalence (8% -12%)
Gender differential
 Adolescent and adult females : males - 2:1
Age of onset
 rare before puberty
 average age at onset is the late 20s.
 may begin at any age, but peak 25-44


Slide 32

Clinical course
 Initial episode may be triggered by stressor
 develop over days to weeks
 Prodromal symptoms -generalized anxiety,
panic attacks, phobias, or depressive
symptoms that do not meet the diagnostic
threshold may occur over the preceding
several months.


Slide 33

Clinical course
 mean duration of a major depressive episode
16 weeks
 Untreated -6 months or longer
 median time to recovery from a major
depressive episode is approximately 20
weeks


Slide 34

Recurrence risk
After one episode – 50-60% for 2nd
 After 2nd episode – 70% for 3rd
 After 3rd episode - 90% +



Slide 35

Episodes may become
more frequent
 More prolonged
 Less treatment responsive
 More spontaneous/autonomous



Slide 36

Partial remission - higher risk for relapse
Longer episode duration- poorer prognosis
More episodes – poorer prognosis

Maintenance of full therapeutic dose for 6-12
months reduces relapse risk by 50%


Slide 37

Implications


Treat Early



Aim for remission



Maintain treatment dose for 6-12
months in remission or indefinitely


Slide 38








Response
Relapse
Remission
Recurrence
Return to premorbid functioning


Slide 39

 Symptom

remission
 Treat comorbid disorders
 Restore premorbid functioning
 Attempt to limit disease
progression.


Slide 40



Safety – where to treat (clinic, hospital)



How to treat



With whom to treat


Slide 41









I General

II Psychotherapy –CBT, IPT
III Biological -Medication, ECT
IV Other – TMS, VNS, deep brain
stimulation


Slide 42





Promote treatment adherence
Pschoeducation – re: illness, treatment
options, patient preference



Exercise – minimum 150 min/wk



Establishing a routine with modest goals


Slide 43

Cognitive behavioural therapy
 Interpersonal therapy
 Solution focused therapy



Slide 44

 Antidepressants

 Augmenting

agents
 Combinations


Slide 45



SSRI - Fluvoxamine, Citalopram, Paroxetine ,
Escitalopram, Sertraline, Fluoxetine



SNRI - Duloxetine, Venlafaxine, Desvenlafaxine



RIMA - Moclobemide



Miscellaneous – Bupropion, Mirtazapine ,


Slide 46




Quetiapine
Tricyclic antidepressants – e.g. nortriptyline,
imipramine, chlomopramine


Slide 47

Monoamine oxidase inhibitors (MAOIs)
e.g phenelzine, tranylcipramine




Slide 48

 Evidence

for superior
efficacy/safety/tolerability


Slide 49





Escitalopram,
Sertraline,
Venlafaxine


Slide 50




Duloxetine
Mirtazapine


Slide 51



Early indication of response after 2-4 weeks



With response allow for a further 2 – 4 weeks



If clear but inadequate response then ADD



If poor response then CHANGE


Slide 52

Previously - change classes e.g. SSRI’S
to SNRI

BUT
No evidence of benefit over change to
same class


Slide 53

Use other agents in the “superior “
group.
 duloxetine,
 escitalopram,
 mirtazapine,
 sertraline,
 venlafaxine


Slide 54

 lithium

 triiodothyronine,
 atypical

antipsychotic


Slide 55

 venlafaxine/mirtazepine

“California Rocket fuel”

 buproprion/SSRI

-

(Escitalopram/citalopram)

 nortriptyline/SSRI’s


Slide 56

 Commonly

done, but limited data
to support this practice


Slide 57









Create a controlled seizure
Right unilateral or bilateral
Increases mono amine neurotransmitters
ECT has the highest rates of response and
remission of any form of antidepressant
treatment, with 70%–90% of patients treated
showing improvement
Potential cognitive side effects


Slide 58

Transcranial Magnetic Stimulation
 Light therapy ( even for non seasonal
affective disorder)
 Deep brain stimulation
 Vagus Nerve stimulation



Slide 59

Recurrence - Risk factors
◦ Persistence of subthreshold depressive symptoms
(relapse)
◦ Prior history of multiple episodes of major
depressive disorder
◦ Severity of initial and any subsequent episodes
◦ Earlier age at onset
◦ Presence of an additional nonaffective psychiatric
diagnosis
◦ Presence of a chronic general medical disorder
◦ Persistent sleep disturbances


Slide 60



common, occurring in 20% of patients
within 6 months following remission.


Slide 61

Remission rates (STAR*D)






First trial
- 36.8%,
Second trial - 30.6%,
Third trial
- 13.7%,
Fourth trial - 13.0%
Total
- 67% with trials, augmentation
and combination strategies

Slide 63












Symptoms never absent longer than two consecutive months.
No major depressive episode during first two years
No manic hypomanic or mixed episodes
The patient has never fulfilled criteria for cyclothymic
disorder.
The depression does not exist only as part of a chronic
psychosis
The symptoms not directly caused by a medical illness or by
substances, including drug abuse, or other medications.
The symptoms may cause significant problems or distress in
social, work, academic, or other major areas of life
functioning.


Slide 64








major depression,
anxiety disorders (up to 50%)
personality disorders (20–40% or more
among those with early-onset DD),
somatoform disorders (2.8%–45.2%),
substance abuse (up to 50%).


Slide 65

As per MDD but response may take
longer
 More likely to maintain treatment
indefinitely



Slide 66

Criteria not met for MDD or DD
 Exclude the exclusion criteria
 Treatment options to consider as per
MDD



Slide 67










Common, more common in women than men
recurrent , progressive, chronic,
Associated with morbidity, comorbidity,
mortality
Repercussions –personal, relationship, societal
Goal of treatment – symptom relief, limit
disease progression, restore premorbid
function.
Using pharmacotherapy, psychotherapy and
other strategies, the majority can be helped
