Depression

Unified Model of Mood Disorders
•
•
•
•

Genetic Vulnerability
Developmental Events
Physiological Stressors
Psychosocial Stressors
This model believes that any of these
can start the cycle of disturbed
neurochemistry
Neurochemical Theories

Serotonin and
Norepinephrine
• 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



Elevated levels of
corticotrophin
releasing hormone
Elevated pituitary
release of
andrenocorticotropic
hormone
Early live exposure
to overwhelming
trauma
Circadian Rhythm
Medications
 Nutritional deficiencies
 Physical illness
 Wake-sleep cycles

Etiology/psychosocial/depression



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
Psychosocial Cont.

Behavioral Theories- Believes that the way
you act effects peoples response
•

Seligman- Developed theory of learned
helplessness, hopelessness and being
unassertive
Loss theory
•
Bowlby-Loss during childhood predisposes
you to depression, esp. another loss
Cognitive Theory
How we think about our situation
 Aims at symptom removal by
identifying and correcting silent
assumptions
 Silent assumption: going to school is
something I am doing for me.

Treatment Efficacy
Depression very treatable disease
 Episodes usually last 6 to 9 weeks
 Endogenous compared to
Exogenous depression

Treatment Efficacy
•
Endogenous means from within
–
•
The client can not describe a specific event that
exacerbated the depression.
Exogenous means from without
–
There is a specific event that triggers the depression
•
•
•
•
Psychotherapy may be enough for exogenous
–
•
Loss of a loved one
Surgery
Retirement
Group Therapy for Grief
Combination is best for endogenous
–
–
Medications
Individual or Group psychotherapy

Issues for Nurses with depressed
Patients

Safety First: The milieu or environment
should keep the client safe
• Check all clients every 15 minutes
• Locked environment



Record amount eaten
Assess client

• Lab work
– A low albumin level or total protein will let you know
the client is not eating well
Decrease Isolation
Approach is firm and direct
 “It is time for our 1-1 or Art Class or
Coping Skills Group”
 Listen and Acknowledge negative
feelings

•
If client has made suicide attempt,
important acknowledge their feeling.
You do not agree with it but you let
them know you heard it.
Other Issues

responsibility

–
•
Initially: memory of events immediately prior to the procedure
Treatment 6-10 times
