Epidemiology
Major
Depressive Disorder (MDD) is
the one of the most common mental
disorders in primary care settings
The
prevalence of current MDD in
primary care settings has been found to
range from 9.2% to 13.5%
MDD
may occur at any age
Natural History of Major Depression
Recurrent, episodic disorder in > 50%
Residual symptoms persist between
episodes in 20-35% (partial remission)
Systemic disorder .
Most serious complication is suicide;
others include marital, parental, social,
and vocational difficulties.
מקרה מספר 1
מורן בת , 30נשואה ואם לבת (בת . )5
הגיע לרופא המשפחה ומתארת עייפות רבה בחודשיים
האחרונים .מורן עובדת כמזכירה ומתארת כי היא מבצעת
שגיאות רבות בעבודתה .המעסיק שלה מעיר לה לאחרונה
על שגיאותיה .מרגישה כי לאחרונה קשה לה יותר
להתרכז .מדווחת על מריבות ומחלוקות בזמן האחרון עם
בעלה בשל לחץ כלכלי בבית .כשמתעוררת בבוקר מרגישה
עייפה ו "לחוצה מהמחשבה שהיא צריכה ללכת לעבודה".
דיווח על התקפי פלפיטציות וכאבים בחזה.
פחות מתעניינת בילדים ומרגישה שפחות משקיעה בהם.
דיון ( מקרה )1
• איזה שאלות היית רוצה לשאול את מורן?
מקרה מספר ( 1המשך)
לאחר שנשאלה מספרת כי מקיצה משנתה בשלוש לפנות
בוקר עם מועקה בחזה .לא הולכת לשיעורי "פילאטיס"
והתעמלות במועדון השכונתי .מבשלת למשפחתה אך
קיימת ירידה בתאבון .לא בטוחה אם יש שינוי במשקל.
מרגישה בטוחה בנישואיה אבל מרגישה כי בעלה פחות
מתעניין בה כי היא שווה פחות במיוחד כי יש לה פחות
עניין בקיום יחסי מין עימו .מפחדת כי בעלה יעזוב אותה.
מרגישה אשמה ביחס לילדיה ולבעלה .מרגישה כי צריכה
להיענש והתאבדות תפתור את בעיותיה .משתמשת יותר
ביין אדום כדי שתוכל לישון.

•האם אתה צריך לראות את בעלה?
•מה תעשה אם היא מסרבת לדבר עם בעלה
כי היא מפחדת שידע כי היא חוששת
לנאמנותו?

Recognition
Depression is difficult to diagnosis in
primary care and often goes
undetected:
depressed mood typically not
presenting complaint
competing demands (acute and chronic
illnesses)
limited resources and time
Major Depression: Four Hallmarks
Depressed Mood.
Anhedonia: loss of interest or pleasure
Physical Symptoms:
sleep disturbance, low energy,
appetite or weight change,
psychomotor changes
Psychological Symptoms:
low self-esteem, poor concentration,
suicidal ideation/obsession
surrounding death.
Assessing for Depression
and Anhedonia
Do not ask patient: “Are you Depressed?”,
INSTEAD, Ask: “How has your mood
been?”
Ask about Anhedonia: “What are you
doing for fun?” OR: “Does your
(pain,anxiety, grief, whatever symptoms
patient mentions) keep you from doing all
the things you enjoy?”

Assessing Risk of Suicide
Assess risk factors:
PRIOR ATTEMPTS
Family history of suicide
Hopelessness
Demographics
Caucasian, male, elderly, lives alone
Clinical
Substance abuse, psychosis,
potentially terminal illness
Assessing for Suicide
Use a gradual, sensitive approach to raise
the subject:
How does the future look to you?
Living with (pain/anxiety/patients’
symptoms) can be very difficult. Do you
sometimes wish your life was over?
Have you had thoughts that you would be
better off dead?
Have you had thoughts of hurting
yourself?
Have you thought about how you might
hurt yourself?
When to Consider Involving Psychiatry
Suicidal
ideation
Psychotic symptoms
Manic symptoms
Current substance abuse
Severe psychosocial problems
Interventions: What can be done?
Depression is one of the most treatable
mental illnesses
• 70% - 75% of all depressed people
respond to treatment
• almost all who receive treatment
experience some relief in symptoms
Medication
Psychotherapy
Electroconvulsive Therapy
Watchful waiting
Management of Depression
Give an adequate trial of treatment
(therapeutic dose for 6-8 weeks)
Follow closely until patient responds
Change treatment if patient doesn’t respond
Continue medication for 6-9 months
minimum.
If patient has a history of 2 or more
previous depression episodes, continue for 2
years or more.

Side Effects
Are relatively common
Are the #1 reason patients give for stopping
medications
Therefore:
Talk to patients about common side effects
Wait - many side effects resolve with time
Consider reducing the dose temporarily
Consider changing to another type of
medication
Consider changing timing of medication
Adjunctive Medications
Anxiety
Consider short term use of a
benzodiazepine
Insomnia
Trazodone – warn about priapism
Antihistamines (hydroxyzine,
diphenhydramine)
Sexual Dysfunction
sildenafil

Depression in Primary Care
Depression In Western Industrialized Nations
(DSM-IV):
Males: 2-3% of population at any given time, and
5-12% for population in lifetime.
Females:5-9% of population at any given time,
and 10-25% for population in lifetime.
Percent of mental disorders accounted for by
depression: Males (up to) 15%, Females (up to) 45%
(rough estimate).
In primary care practices 5-9% patients at any
given time have Major Depression (it is estimated
that only one third to one half are recognized by
practitioners).
Consequences of Untreated Depression
Depression is the 2nd leading cause of
disability in industrialized countries
Depression associated with:
2x increased risk of death overall
26x increased risk of suicide
Impaired social functioning
Consequences of Untreated Depression
(continued)
Depressed patients visit primary care
provider 3x more than non-depressed
patients
2-5x increase in days absent from work
Cost of depression in US in 1990
estimated to be $44 billion

Drug Interactions
Sertraline and citalopram have no
clinically significant drug interactions
through the CYP450 system
Fluoxetine and paroxetine are potent
2D6 inhibitors
Nefazodone is a potent 3A4 inhibitor
Common Barriers to Treatment
Practical Barriers
Ethnic/Cultural barriers
Patient doesn’t agree with diagnosis or
plan
Patient doesn’t understand treatment
plan
Patient is afraid of becoming addicted
to antidepressants
Common Barriers to Treatment (Continued)
Side effects
Patient forgets to take medications or
runs out early
Formulary restrictions
Friends or family are not supportive
Treatment is ‘not working’; patient feels
hopeless
Treatment ‘is working’; patient is better
and wants off
Adherence
20-50% of patients “drop out” in the
first month of treatment
30-50% of patients don’t have a
complete response to the initial
treatment
If patient is not better at 8 weeks,
consider changing medication, adding
psychotherapy, or getting a psychiatric
consultation
Improving Medication Adherence
Tell patients:
Medications take time to work
Medications are not addictive
Take medications every day as ordered
Take medications even if you feel better
Do not stop medication before first
contacting your physician
Engage in pleasant activities
Call your provider if you have questions
What To Do If Patients Don’t Get Better
Wrong
diagnosis?
Insufficient dose?
Insufficient length of treatment?
Problems with barriers to
adherence?
Side effects?
Other complicating factors?
Wrong treatment?
Continue Medication for 6-9 Months or
More
Medications should be continued for 6-9
months after the patient gets better
People at high risk for relapse (those with at
least two prior episodes of major depression,
dysthymia, or residual depressive symptoms)
should get a full dose of medication for 2
years or more to prevent recurrences
See patients at least every 3 months
What To Do If Patients Relapse
Assess adherence to medication
regimen
Examine for new stressors
Restart treatment at the last
effective dose of antidepressants
or consider an increase in dose if
patient is still taking medication
Consider adding psychotherapy
Consider psychiatric consultation
Preparing the Patient for a Mental Health
Referral
Bring up the possibility of a mental
health consultation when first
presenting the diagnosis of depression
to the patient.
The request for a mental health
consultation is simply a matter of
obtaining another professional opinion.
Draw the analogy of referrals made to
other medical specialist, like
cardiologists, endocrinologists, etc.
Side Effects of Other Antidepressants
bupropion (Wellbutrin)
Main contraindication is seizure disorder or
eating disorder
Also effective for smoking cessation
Less sexual dysfunction than others
mirtazapine (Remeron)
Sedation
Weight gain
venlafaxine (Effexor): Relative contraindication if
HTN is present
nefazodone (Serzone): Carries a black box warning
for liver failure
Antidepressant Dosing
Once a day dosing:
Give sedating meds at bedtime
(paroxetine, mirtazapine, nefazodone)
Activating meds (fluoxetine) in the
morning
Starting dose is lower with the elderly, with
the medically ill, and if there is a comorbid
panic disorder.
Titrate to therapeutic dose as tolerated by
side effects
