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


turned on the self; overactive superego
Sullivan-problems in the interpersonal

•
•
•
•
Psychotherapy may be enough for exogenous

•
Loss of a loved one
Surgery
Retirement
Group Therapy for Grief
