Review Common Psychiatric Diagnoses
presenting in the primary care setting
Review available pharmacologic
treatment options
Depressive Disorders
History
Prevalence: 15% total, 25% woman
Cost: estimate $45-55 Billion annually in U.S.
Treatment: 2/3 of people with depression do not
realize they have it (Andrew, 3/2012) and only 20% of
those diagnosed received appropriate treatment
Depressive Disorders
Depressed patients lose on average 5-6 hours of
productive work every week
Depressed patients are more than 2 times likely to take
sick days
Depressed patients are 7 times more likely to be
unemployed
Depressive Disorders
Depressed patients have an 11% decrease in the
probability of getting married
Patients have a 35% decrease in lifetime income due to
depression
Rates of undetected depression among drug and
alcohol users are estimated to be at least 30%
Depressive Disorders
According to WHO, depression was the 3rd most
important cause of disease burden worldwide in 2004
A Toronto study showed workers who were treated for
severe depression were 7 times more likely to be high
performing than those who were not

Etiology
Cause Unknown
Causative factors divided into biological factors,
genetic factors, and psychosocial factors
Biological Factors
Mood disorders associated with dysregulations of biogenic
amines norepinephrine, serotonin, dopamine
Adrenal Axis: Hypersecretion of cortisol
Thyroid Axis: Abnormal regulation, autoimmune disorder
(10% have antithyroid antibodies)

growth hormone release

50% in monozygotic twins
Diagnosis

Qualifiers: Severity, Psychotic, Recurrent, Single,
Remission
