Major Depressive Disorder
而它造成一種下墜的運動

憂鬱的氛圍緩緩流動
並從你身邊掠過
而你有天將察覺它
在這地獄般的世界
它不會讓每日醒來的日子
變得更好過。

remission： resolution of depressive symptoms
 Maintenance stage－
– to resolve residual symptoms
– to return to full pre-morbid functioning
– to reduce risk of recurrence
– to treat co-morbid conditions

Possible Dose-Side Effect Relationship of Antipsychotic
Drugs: Relevance to Cognitive Function in Schizophrenia
Cognitive function, such as verbal learning memory,
working memory, executive function, verbal fluency and
attention/information processing, is the most influential
determinant of outcome in patients with schizophrenia.
 Atypical antipsychotic drugs have been shown to be more
efficacious in treating cognitive disturbances of
schizophrenia compared with typical antipsychotic drugs.
Serotonin (5-hydroxytryptamine [5-HT]) receptor subtypes,
such as the 5-HT1A receptor, are considered to mediate
the ability of antipsychotic drugs to enhance cognition.
 On the other hand, treatment with some atypical agents,
such as risperidone, may deteriorate working memory in
some people with early-stage schizophrenia.
 The paradoxical side effects of these antipsychotic drugs
in terms of cognition may be attributable to dose, duration
of treatment and type of cognitive domain.

Clinical Staging of Psychotic or Mood disorder
St.
Definition
0
Increased risk of psychotic or severe mood disorder. No symptoms currently.
1a
Mild or non-specific symptoms, including neurocognitive deficits of psychosis or
severe mood disorder. Mild functional change or decline.
1b
Ultra high risk: moderate but subthreshold symptoms, with moderate neurocognitive
changes and functional decline to caseness (Global Assessment of Functioning [GAF] < 70)
2
First episode of psychotic or severe mood disorder. Full threshold disorder with moderatesevere symptoms, neurocognitive deficits and functional decline (GAF 30-50)
3a
Incomplete remission from first episode of care. Could be linked or fast-tracked to
Stage 4.
3b
Recurrence of relapse of psychotic or mood disorder which stabilizes with
treatment at a level of GAF, residual symptoms, or neurocognition below the best
level achieved following remission from first episode.
3c
Multiple relapses, provided worsening in clinical extent and impact of illness is
objectively present.
4
Severe, persistent or unremitting illness as judged on symptoms, neurocognition
and disability criteria.

Functioning after a major depressive episode:
complete or incomplete recovery?

60-85% of the
respondents did better
or showed no change
on different scales
after recovery from
MDE.

Co-morbid substance use
disorder and anxiety
disorder, presence of
somatic illness, external
mastery, low social support
and high baseline
functioning were predictors
of worsened functioning.

Major depressive disorder: psychosocial
impairment and key considerations in functional
improvement.


Patients who achieve full asymptomatic remission
from depressive symptoms can still experience
functional impairment; thus, restoring psychosocial
functioning is increasingly being identified as an
important goal of depression therapy.
The more effective the therapeutic approach
employed to resolve symptoms of depression (eg,
long-term duration of treatment, monitoring of patient
adherence to treatment, maintenance of
asymptomatic remission), the more likely it is that
patients with MDD will experience a full restoration of
premorbid psychosocial functioning.

Risks of slow response to
antidepressant treatment
Prolongs the vocational disability, an increasing risk for chronification of
the current illness episode. The length of the current untreated episode of
illness may be the strongest predictor of overall short-term and long-term
outcome in major depression.*1
 The slow response of antidepressant treatment is connected with
suicidality. Achieving a more rapid and enhanced treatment response,
targeting core depressive symptoms including hopelessness, could help to
substantially reduce the incidence.*2
 Limits quality of life, particularly through its impairment of the cognitive
skills necessary for work, creating and maintaining relationships, being
productive, and functioning in multiple domains.*3
 Increases the patient’s subjective experience of a lack of treatment
efficacy, which may lead to frustration and damage to the patient doctor
relationship, usually finally resulting in poor compliance rates.*4

Consideration of metabolic risk
when starting SGA
If a patient gains ≥5% of his
or her initial weight during therapy,
one should consider switching the
SGA
If a patient develops worsening
glycaemia or dyslipidaemia while on
antipsychotic therapy, one should
consider switching to an SGA that
has not been associated with weight
gain or diabetes
Non-pharmacological strategies

Psychotherapy (often in conjunction with
pharmacotherapy), CBT/ interpersonal
psychotherapy

Electroconvulsive therapy (ECT)

Vagus nerve stimulation (VNS). The US
FDA recently approved vagus nerve
stimulation as adjunctive therapy (after
four prior treatment failures); however,
its benefits are seen only after
prolonged (up to 1 year) use.

Other nonpharmacological options, such
as repetitive transcranial stimulation,
deep brain stimulation or psychosurgery,
remain experimental and are not widely
available.
Therapeutic options for treatment-resistant
depression. CNS Drugs. 2010 Feb;24(2):131-61.



Clinical experience tells us that such
treatment-resistant patients are difficult to
manage when the next depressive
episode appears, because the previous
treatment history causes both the patient
and the clinician to develop treatment
strategies that include more intensive
methods of treatment (ie, higher doses,
drug combinations, augmentation
strategies, etc).
Thus, in addition to biological treatment,
psychosocial interventions (cognitive
behavioral therapy, emotion-focused
therapy, self esteem therapy) should be
recommended.

Are Antidepressant Drugs That Combine Serotonergic and Noradrenergic
Mechanisms of Action More Effective Than the Selective Serotonin
Reuptake Inhibitors in Treating Major Depressive Disorder? A Metaanalysis of Studies of Newer Agents

Methods：Medline/Pubmed, EMBase, clinical trial registries, program syllabi from major
psychiatric meetings held since 1995, and documents from relevant pharmaceutical
companies were searched for double-blind, randomized trials comparing a newer
serotonergic-noradrenergic antidepressant drug (venlafaxine, duloxetine, milnacipran,
mirtazapine, mianserin, or moclobemide) with an SSRI for MDD.

Results：Ninety-three trials (n = 17,036) were combined using a random-effects model.
Treatment with serotonergic + noradrenergic antidepressant drugs was more likely
to result in clinical response than the SSRIs (risk ratio [RR] = 1.059; response rates
63.6% versus 59.3%; p = .003).

Conclusions：Serotonergic-noradrenergic antidepressant drugs seem to have a modest
efficacy advantage compared with SSRIs in MDD. With the Number Needed to Treat (NNT)
statistic as one indicator of clinical significance, nearly 24 patients would need to be
treated with dual-action antidepressant drugs instead of SSRIs in order to obtain one
additional responder.

Treatment strategies for depression:
WFSBP 2007 guidelines
Partial or nonresponse to 2-4 week treatment with
an antidepressant at adequate dosage
Consider treatment optimisation
(1. dose increase)
2. Combining
two antidepressants
from different classes
4. Augmentation
strategies
Consider adding psychotherapy
at any time during treatment
3. Switch to a new
antidepressant from a
different or same
pharmacologic class
Consider ECT only in special
circumstances e.g. severe
psychotic depression
Bauer et al. WFSBP (World Federation of Societies of Biological Psychiatry ) 2007 guidelines
1. Increasing dosages
Dose-Response Effects with Fluoxetine
HAM-D Total
Dornseif et al, 1989
2. Combining two antidepressants from
different classes
CO-MED: Rates of remission and response in
a comparison of AD monotherapy with 2 AD combinations
Rush et al 2011
3. Switching Strategy:

(1) Retrospectively, switching class of antidepressants has no
advantage in TRD.

(2) In a large group of treatment resistant depression with a failure to
respond to at least 1 adequate antidepressant treatment in open treatment,
switching to a different class n=281 was non-significantly better than
switching to an antidepressant of the same class n=59.

Lithium, valproate, selective serotonin reuptake inhibitors (SSRIs), tricyclic
antidepressants (TCAs), and other treatment, such as electroconvulsive
shock therapy (ECT), all increase post-synaptic 5-HT1Areceptor signaling
through either direct or indirect effects.
Reduced somatodendritic and postsynaptic 5-HT1A receptor numbers or
affinity have been reported in some post-mortem studies of suicide victims,
a result consistent with well-replicated PET analyses demonstrating reduced
5-HT1A receptor binding potential in diverse regions such as the dorsal
raphe, medial prefrontal cortex (mPFC), amygdala and hippocampus.
5-HT1A receptor knockout (KO) mice display increased anxiety-related
behavior, which, unlike in their wild-type counterparts, cannot be rescued
with AD treatment.
In humans, the G allele of a single nucleotide polymorphism (SNP) in the 5HT1A receptor gene (HTR1A; rs6295), which abrogates a transcription factor
binding site for Deaf-1 and Hes5, has been reported to be over-represented
in MDD cases. Conversely, the C allele has been associated with better
response to AD drugs.
We raise the possibility that 5-HT1A receptor dysfunction represents one
potential mechanism underpinning MDD and other stress-related disorders.

Possible Dose-Side Effect Relationship of Antipsychotic
Drugs: Relevance to Cognitive Function in Schizophrenia
Cognitive function, such as verbal learning memory,
working memory, executive function, verbal fluency and
attention/information processing, is the most influential
determinant of outcome in patients with schizophrenia.
 Atypical antipsychotic drugs have been shown to be more
efficacious in treating cognitive disturbances of
schizophrenia compared with typical antipsychotic drugs.
Serotonin (5-hydroxytryptamine [5-HT]) receptor subtypes,
such as the 5-HT1A receptor, are considered to mediate
the ability of antipsychotic drugs to enhance cognition.
 On the other hand, treatment with some atypical agents,
such as risperidone, may deteriorate working memory in
some people with early-stage schizophrenia.
 The paradoxical side effects of these antipsychotic drugs
in terms of cognition may be attributable to dose, duration
of treatment and type of cognitive domain.

Rumination

Rumination is defined as
the compulsively focused
attention on the symptoms
of one's distress, and on
its possible causes and
consequences, as
opposed to its solutions.

Lyubomirsky, S.(2008)Rethinking
rumination. "Perspectives on
Psychological Science", "3.5" 400-424.

At least two previous
studies found that
ruminative responses
predicted episodes of
depression. (Just & Alloy,
1997; Roberts, Gilboa, &
Gotlib, 1998).

Ruminative response : A Trans-diagnostic Process
* It appears that rumination is a stable trait that is present in individuals
both during active states of depression and remission (Lyubomirsky et
al., 1998,1999).
* Repetitive thoughts related to personal concerns occur in several anxiety
disorders, including social anxiety, GAD, OCD, and PTSD. The
presence of rumination across these various disorders suggests that
rumination is a trans-diagnostic process (Abbott and Rapee, 2004;
American Psychiatric Association, 1994; Ehlers et al., 1998; Van Oppen et
al., 1995).
* Additionally, several prospective longitudinal studies have shown that
rumination predicts levels of both anxiety and depressive symptoms
(Hong, 2007; Nolen-Hoeksema, 2000;Sarin et al., 2005).
* One such study by Johnson et al. (2008) found that both undergraduates
diagnosed with bipolar disorder and those diagnosed with MDD
experienced heightened levels of rumination.

Rumination and Dopamine(1)


Dopamine might enhance the capacity of individuals to reject
negative thoughts. Specifically, when dopamine levels are limited,
activation of brain regions tends to be more diffuse than
concentrated (e.g., Bush, 2010).
Presumably, if dopamine levels are low, brain activation is
significantly dependent upon random noise--that is, fleeting states,
thoughts, or conditions--rather than more sustained patterns of
cognition. Therefore, many regions of the brain are activated
marginally. In contrast, if dopamine levels are high, specific
cognitions prevail, and activation is more confined to particular
regions.
Bush, G. (2010). Attention-deficit/hyperactivity disorder and attention networks.
Neuropsychopharmacology, 35, 278-300.
59
Rumination and Dopamine(2)



Diffuse rather than concentrated activation can
undermine the efficiency of some brain regions.
To illustrate, the left inferior frontal gyrus, which
primarily overlaps with the ventrolateral
prefrontal cortex, partly underpins the inhibition
of unwanted thoughts.
As Berman et al. (2011) showed, when
activation in this region was diffuse rather than
concentrated to specific locations, people could
not inhibit negative words as effectively.
Presumably, this diffuse activation implies the
individuals cannot focus on specific classes of
stimuli efficiently. They attempt to inhibit a broad
range of stimuli, compromising efficiency.
This limitation could underpin the rumination that characterizes
depression. In particular, dopamine is often limited in depressed
individuals (e.g., Hasler et al., 2008). Thus, activation of specific regions,
such as the left inferior frontal gyrus, may be more diffuse. Negative
thoughts, therefore, cannot be as readily inhibited.

and rumination. Cognitive, Affective, and Behavioral Neuroscience, 11, 85-96.

Rumination-focused cognitive–behavioural therapy
for residual depression: phase II randomised
controlled trial
One potential way to improve the efficacy of CBT for residual or
chronic depression is to adapt it to specifically address core residual
symptoms such as depressive rumination, defined as repetitive
thinking about the causes, meanings and implications of
depressed feelings, symptoms, problems and upsetting events.
We modified CBT to target rumination because rumination: (a)
remains elevated after remission from depression; (b) is associated
with less treatment response; and (c) prospectively predicts the
onset, severity and duration of depression.
The
British Journal of Psychiatry (2011) 199, 317–322.
Conclusion






1. Around 60% of patients do not achieve remission after treatment
by first-line antidepressants.
2. The target goal of treatment for MDD should be functional
recovery, emphasizing timing, active treatment of residual s/s,
side effects and duration.
3. Understanding non-response of antidepressant, emphasizing
dosage, duration and drug adherence.
4. Augmentation or switch strategy: Considering the advantages,
disadvantages, evidence and indication.
5. The Role of SGA for augmentation treatment: As more evidence
confirmed, choosing the good candidate, intervening earlier and
monitoring the related side effects might be warranted.
6. The mechanism of SGA for TRD remained to be further studied,
esp. the role of 5-HT1A receptor, dopamine and rumination.
