Objectives
At the end of the talk participants
will be able to:
Describe the range of Mood Disorders women
experience
Recognize post partum mood disorders
Prescribe medications for depression in women
and know when to refer
Mood Disorders =
Affective Disorders
• Disturbance in mood
• Inappropriate, exaggerated, or limited range of
feelings
• Everybody gets down, and everybody
experiences excitement and pleasure
• Mood disorder: feelings are extreme
• Crying, and/or feeling depressed, suicidal
• Or excessive energy, sleep not needed for days
and decision making significantly hindered
Common Disease
•
•
•
•
10% of primary care adult patients
3x visits as non-depressed patients
Occurs in all demographic groups
Occurs in women double the rate in men
–
–
•
20% lifetime incidence
50% occurs between ages 25-44 years
Common cause of slow recovery from
physical illness
Precipitating Events
Life events which can precipitate depression
• Loss of a parent or sibling in early childhood
• Loss of a limb or another part of the body
(mastectomy)
• domestic violence
• miscarriage
• loss of self-esteem
• divorce or separation
Depression and Disability
• More disability days than any other chronic
condition except coronary artery disease
• More chronic pain than any other chronic
disease except arthritis
• WHO: 2nd most important cause worldwide
of life years lost to disability (2020)
• $31.3 billion/year in the United States (1990)
Poorly Recognized and Treated
• Under-recognized
– 80% of patients are undiagnosed
– Only 20% of patients receive treatment
– 80% of patients respond to treatment
• Anxiety often due to depression
• Patient may present with smiling or able to
laugh, w/o obvious depressed mood- known
as masked depression
• Universal screening is necessary
Barriers to Diagnosis:
Clinician

Failure to recognize somatization

Distinguishing sadness from depression

Discomfort with emotional issues

Misdiagnose as organic or hormone related

Concern that assessment is timeconsuming

Difficulties in obtaining a referral
Barriers To Diagnosis:
Patients

Resistance to diagnosis of a mental
disorder

Belief it is natural to be depressed
sometimes

Belief they can will themselves well

Shame

Cultural Issues
Suspect The Diagnosis:
Clinical Presentation
 Multiple visits for vague complaints

Depressed voice, expression, or posture

Pain syndromes: vulva, pelvic, vagina,
menses, coitus, urinary tract

Clinician feels sad during or after visit
Forms Of Depression In
Women
• Unipolar forms
–
Major depressive disorder
– Chronic depression (dysthymia)
• Bipolar mood disorder (manic-depression)
• Other distinct syndromes in women
Eating disorders
– Premenstrual dysphoric disorder (PMDD)

– Severe:
•
always prevents ADL*
Chronic depression = dysthymia
*ADL: activities of daily living
Major Depression Disorder
MDD, Single episode
• Absence of mania or
hypomania
MDD, Recurrent
• 2 major depression
episodes, separated
by at least a 2 month
period with more or
less normal
functioning/mood
DSM IV Criteria For Major

–
–
–
–

–
Depressed mood and/or anhedonia (required)
Low self-esteem (worthlessness)

Screening With 2 Questions
• Depression is present if 1 or both
present:
“In the past month have you been often
bothered by. . .
. . . depressed mood?”
. . . lack of interest or pleasure?”
Whooley MA, Avins AL, Miranda J, Browner WS. Case-finding
instruments for depression: Two questions are as good as
many. J Gen Int Med 1997;12:439-445.
Direct Questions to Ask
Depressed mood
"How's your mood been lately?"
Anhedonia
–
Loss of interest or pleasure
– Lack of enjoyment in most daily activities
"What have you enjoyed doing lately?"
"Are you getting less pleasure in things you
typically enjoy?"
Direct Questions to Ask
• Other symptoms
"Have you been feeling down on
yourself?"
"How are you eating; sleeping?”
"How's your energy level?"
"Do you ever feel like life is not worth
living?"
"How's your concentration?"
Mnemonic: “Space Drags”
S leep disturbance
D epressed mood
P leasure/interest (lack of) R etardation movement
A gitation
A ppetite disturbance

depression
• Asking does not insult patient or initiate
thought
• Ask direct questions:
"Have you had thoughts of hurting yourself?"
"Do you sometimes wish your life was over?"
"Have you had thoughts of ending your life?"
Suicidal Assessment
• If yes, assess immediate risk:
"Do you feel that way now?”

"Do you promise to call me immediately if your
suicidal thoughts get stronger?”

to have a mood disorder (particularly for
bipolar disorder)
Women: Heritability rates are higher
Grief Reactions

Does Hormonal Contraception
Cause or Worsen Depression?
• Older studies suggested progestins could
– Make pre-existing depression worse
– Cause depression in a small % of users
– “More likely” with progestin-only methods
• Newer (and better) studies show that neither
of these assertions are correct
• 2010 CDC Medical Eligibility Criteria (MEC):
– In depressed women, all methods are
categorized as US MEC 1
Depression In Pregnancy
• Include the patient in decision-making
–
–
Overall well-being & Ability to function
Weigh risks and benefits
•
Untreated depression in pregnancy leads to
increased risk of postpartum depression
•
One study found both SSRIs & untreated
depression associated with preterm birth
Major depression and antidepressant treatment: impact on pregnancy and neonatal
outcomes. Wisner KL - Am J Psychiatry - 2009; 166(5): 557-66 Treatment of Mood
Disorders During Pregnancy and Postpartum Cohen et al 2010; 33(2): 273-293
Safety Of Drugs In Pregnancy

Fluoxetine best studied SSRI for safety and efficacy in
pregnancy and lactation. >1500 in-utero exposures have
been reported w/o evidence of teratogenicity Avoid
Paroxetine
•
SSRIs and SNRIs are category C
•
Wellbutrin is category B
•
2005 meta-analysis of prospective comparative studies
found no increased risk of anomalies

flu-like symptoms, sensory disturbances,
anxiety, irritability
• Onset 1-3 days after stopping Rx, last an average
of 10 days, usually mild and transient
• Case reports of severe discontinuation symptoms
• PaxilR and ZoloftR > ProzacR (shorter half-life)
• Noncompliance leads to discontinuation
symptoms
• Avoid by tapering drug in weekly increments
Herbals
• St John's wort (hypericum perforatum):
–
mild antidepressant, sedation, anxiolysis
–
headache most common side effect
–
Many studies show induction of CYP450
–
Does decrease efficacy of estrogen based
contraception
Follow Up
• Phone call in 3 days to assess side effects
• 1,2 or 4 weeks according to severity
–
Phone can be used to titrate dose
– Use flow sheet to score symptoms

• Consider role of prophylactic maintenance
Rx if current episode is a relapse
Office Interventions

Assess for adverse personal
relationships

Assess family and community support

Consider self-help groups

Pursue watchful waiting with periodic
follow up
