What Does Depression
Look Like?

Symptoms

Alterations of Cognition






Inability to concentrate
Confusion
Easily distracted
Problems with thinking, ideas and problem-solving
Uninterrupted self-defeating ruminations
Alterations of Affect
Low-self esteem
 Worthlessness
 Guilt
 Anxiety
 Hopelessness

Symptoms

Alterations of a
Physical Nature
 Somatic Complaints
 Preoccupation with
their bodies
 Panic Attacks in
15% to 30% of
people with MDD
Symptoms of Depression

Alterations of Perception:
Usually mood-congruent


Hallucinations
 Voices accusing or blaming of self
Delusions (really, these are cognitive
alterations!)


Delusions of Persecution:
 e.g. For a moral or ethical mistake
Somatic Delusions
 e.g. “I am full of cancer”
Depression Model and Theories

Unified Model of Mood Disorders
Genetic Vulnerability
 Developmental Events
 Physiological Stressors
 Psychosocial Stressors

Any of these can start the cycle of
disturbed neurochemistry
Neurochemical Theories

Serotonin and
Norepinephrine
 Level is altered at
the receptor site
 Receptor sensitivity
changes
 The cells they
activate have lost
the capacity to
respond
Genetic Theories


Depression, major correlation, but not
clear
Two thirds of twins are concordant for
MDD if one or both parents have MDD
Endocrine Theory



Elevated levels of
corticotropin-releasing
hormone
Elevated pituitary release of
andreno-corticotropic
hormone
Early life exposure to
overwhelming trauma
dysregulates stress
hormone levels and 
ability to tolerate stress
Circadian Rhythm Theory





Medications
Nutritional deficiencies
Physical illness
Wake-sleep cycles
Hormonal fluctuations
Anything that disrupts circadian rhythms may
trigger depression
Psychosocial Perspectives



Freud believed depression was anger turned on
the self; overactive superego
Sullivan-problems in the interpersonal areas of
neglect, abuse, rejection, loss
Cognitive theories


Beck-Depression based on distorted thinking patterns
Ellis-Concept of neg. self talk and catastrophising
Beck Depression
Inventory:
Assesses severity of
depressive symptoms
Psychosocial Perspectives, con’td.

Behavioral Theories- The way you act affects
people’s response


Seligman- Developed theory of learned helplessness,
hopelessness and being unassertive
Loss Theory

Bowlby-Loss during childhood predisposes to
depression, esp. another loss
TREATMENT FOCUS:
Cognitive Theory



Core beliefs= How you think about your situation
Identify self-defeating thoughts, beliefs
Change beliefs and you will change behavior
(For more info. on Cognitive Theory, review p.27-28, 30)
Treatment Efficacy




Depression very treatable disease
Episodes usually last 6 to 9 weeks
Endogenous: no identifiable trigger or
event – tx: medications with
psychotherapy
Exogenous: identifiable event(s) or
stressor(s)– tx: counseling/psychotherapy
may be enough to resolve symptoms
Some Nursing Dx. For
Depressive Disorders






Alteration in Nutrition: Less than body
requirements
Sleep pattern disturbance
Self care deficit
Alterations in perception:Hallucinations
Alteration in thought process: Delusions
Potential for Violence: directed at self,
or Risk for Suicide
Goals for the Depressed Patient
Problem
-Sleeps all day
-Doesn’t want to do anything
because he is a failure
-Having thoughts of suicide
-Stays alone in room
-Anxious, ruminating, restless
-Believes she may infect others
with a disease
Goal
Nursing Care and Milieu
Management

Safety First: The milieu or environment
should keep the client safe




Check all clients every 15 minutes
Locked environment
Remove all harmful items

Mirrors, pocket knifes, razors, shoelaces, hangers
Balance Sleep/activity




Assess hours of sleep
Encourage exercise/Walking
Relaxation tapes
Medication as needed for sleep
Nursing Care and Milieu
Management

Monitor and Provide Adequate Nutrition





Observation of client during meals
Record weight < weekly
Record amount eaten
Vital signs
Lab work
 A low albumin level or total protein will let you
know the client has not been eating well
Nursing Care, Milieu, cont’d

Decrease Isolation
Approach is firm kindness and being direct
e.g. “It is time for our 1-1 (or Art Class or

Coping Skills Group)”

Listen and Acknowledge Negative
Feelings

Acknowledge even the most negative or
suicidal feelings. You do not agree with them,
but you let them know you hear them.
Interventions for Other Issues

Anger: writing, discussing, and

Agitated depression: walk

exercise
with patient
Simple, structured
activities best in early
treatment (why?)
Group Therapies






Assertiveness training
Coping Skills
Grief group
Art therapy
Insight oriented
psychotherapy (outpatient)
Family therapy
Nurse-Client Communication





Establish trust
 Show sincere concern
Assess client’s negative
self-talk
Provide another point of view
 Do not attempt to reason
 Don’t reinforce delusions
May be resistant to come to
1-1
Active listening, non-directive
style

Cognitive Therapy Strategy
 Have client list 3 negative
thoughts about self
 This must be limited in number
or could initiate rumination
 Have client list 3 positive
qualities about self
 Talk with client about positive
qualities
 Goal = to begin to replace
negative thinking with more
positive thoughts
Medications

Antidepressants
Tricyclics (TCAs)
 Serotonin re-uptake Inhibitors /SSRIs
 Monoamine Oxidase Inhibitors (MAOIs)
 Atypical/Novel Antidepressants (SNRIs,
NDRIs, and receptor antagonists)

See Chart in Keltner, pp. 182-183
Other Medications Used for
Depression
 Antianxiety medications



Atypical Antipsychotics
Psychostimulants (amphetamine)
OTC meds:


St. John’s Wort (hypericum)--herbal remedy
SAM-e –natural remedy, generally considered
safe
Comparison of Modes of Action

Tricyclics:



a) Non-selectively inhibit reuptake of serotonin, also
norepinephrine and dopamine (somewhat)
b) Increase receptivity to serotonin and
norepinephrine
SSRI’s: Selective inhibition of serotonin reuptake 
fewer side effects
Antidepressant
Side Effect Profiles

TCAs









Dry mouth
Blurred vision
Constipation
Sedation
 appetitewt gain
Postural hypotension
Cardiac effects
 Can be cardiotoxic
 EKG prior to starting
Slow onset 2-4 weeks
Overdose potential

SSRIs







Nausea
Nervousness, anxiety
Insomnia
Sexual dysfunction
Headache
Slow onset 2-4 weeks
 This length of time
is a consideration if
client is suicidal
Low OD risk
Ethical Issue: SSRIs and Suicide

Activating effects of some SSRI
medications appear to be implicated in
increased suicidal behavior (to be
discussed in suicide lecture)
Client Teaching: Managing
Common Medication Side
Effects

Orthostatic Hypotension


Insomnia



Hydrate
Hard candy or gum
Drowsiness


Schedule dose early in day
Dry mouth


Teach the patient to rise slowly
Schedule dose at night
Cardiac effects

Tricyclics may be supplied one week at a time
Serotonin Syndrome



A potentially fatal syndrome
Too much serotonin
Results from: Combination of therapy
 Serotonin Reuptake Inhibitors combined with:
 Prescribed:
 Tricyclic Antidepressants
 Monoamine Oxidase Inhibitors
 Lithium
 Over-the-Counter Medications:
 Cough and cold meds.
 Diet drugs
 St. John’s Wort
 Other
 LSD, Ecstasy
Serotonin Syndrome, cont’d

Symptoms:







CNS-confusion
Agitation
Hypomania
Myoclonus
Tremor
Hyperreflexia
Autonomic signs





Fever
Tachycardia OR bradycardia
Hypertension OR hypotension
Diaphoresis, diarrhea
Severe dehydration can be fatal
Serotonin Syndrome
Monoamine Oxidase Inhibitors
(MAOIs)
 Inhibit enzyme that breaks down
serotonin and norepinephrine
 Non-Selective (older) and Selective types
 Usually last choice of pharmacotherapy
Side Effects of MAOIs



MAOIs can cause very serious
hypertensive crisis
Client must be instructed not to
drink red wine, beer, eat aged
cheese, yogurt, pickled foods,
sausage, etc. anything
fermented/preserved: Tyramine is
chemical ingredient.
Check with MD before taking any
new meds.

AVOID
Atypical/Novel
Antidepressants


Prevent reuptake of specific
neurotransmitters, e.g.
 Serotonin and Norepinephrine (SNRI)
 Norepinephrine and Dopamine (NDRI)
or are
Receptor Antagonists - increase activity of
neurotransmitters
Side Effects of Atypicals




Trazodone/Desyrel- Usually used for sleep: rare
side effect: priapism
buproprion/Wellbutrin: seizures at high doses,
irritability, decreased appetite, worsening of tics
venlafaxine/Effexor: Nausea, agitation,
headache and increase in blood pressure
mirtazapine/Remeron: Sedation, increased
appetite
Other Medications

Used in conjunction with an
antidepressant for treatment of variants of
depression e.g. agitated-type depression,
or for treating anxiety, psychosis or severe
cognitive symptoms
Somatic Therapy:
Electroconvulsive Therapy
(ECT)

Beneficial for for Clients with:



Severe Depression
Depression that is resistive to treatment with
medications
Older adults
 Renal disease or liver disease
 With increased blood serum levels of
medication
ECT, cont’d

ECT seems to balance dopamine and serotonin







Under supervision of anesthesiologist
Pre-op: Give atropine, barbiturate, muscle relaxant
Procedure: Induction of seizure via electrical current
Side effects- short term memory loss
 Initially: memory of events immediately prior to the
procedure
Treatment series of 6-10 times
 Spaced several days apart
After treatment: monitor LOC, orientation, vitals, resp.
Client may have immediate relief of depression
