Functional Somatic Syndromes
Several related syndromes characterized by:
symptoms, suffering and disability
rather than
demonstrable tissue abnormality
![Page 7: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/7.jpg)

Amplification and Maintenance of Somatic Symptoms
Five Factors:
1. The belief that one is sick
2. Future expectations and the Role of Suggestion
3. The Sick Role
4. Stress and Distress.
5. Political, Economic, and Legal issues
![Page 13: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/13.jpg)
Amplification and Maintenance of Somatic Symptoms
1. The belief that one is sick Effect of cognitive beliefs on interpretation of current
symptoms. e.g. hypertension and absenteeism Effect of cognitive beliefs on interpretation and
recall of past symptoms
e.g. healthy volunteers given imaginary diagnosis Amplified through self-scrutiny, medical scrutiny,
media / public health attention, advocacy groups
![Page 14: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/14.jpg)
Amplification and Maintenance of Somatic Symptoms
2. Future expectations and the Role of Suggestion
Cognitive processing of current bodily sensations guided by expectations of what we will experience next.
e.g. ASA for UAP – 6 X dropouts for GI symptoms (- endoscopy) if consent form explicitly mentioned
![Page 15: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/15.jpg)
Amplification and Maintenance of Somatic Symptoms
3. The Sick Role
– social labeling theory:
“… the connotations and implications of the label we
apply to a condition or state influence the outcome of
that condition or state.”
- changes interactions with family, employer & physician
![Page 16: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/16.jpg)
Amplification and Maintenance of Somatic Symptoms
4. Stress and Distress.– Exacerbates and perpetuates physical symptoms– lowers threshold for medical help seeking– ambiguous body sensations more likely attributed to
disease.
![Page 17: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/17.jpg)
Amplification and Maintenance of Somatic Symptoms
5. Political, Economic, and Legal Issues
political climate of entitlement sense of belonging to a group secondary gain e.g. prolonged rehab. in workers
compensation
![Page 18: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/18.jpg)
2. Chronic Fatigue Syndrome
“…fatigue is very common, CFS is not ”.
Caplan. CMAJ 1998;159(5):519-520.
![Page 19: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/19.jpg)
CDC Criteria for CFS:
1. Fatigue > 6 mos., resulting in decrease in activities of > 50%.
and
2. All of: - New or definite onset - Not from ongoing exertion
- not alleviated by rest
and
![Page 20: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/20.jpg)
CDC Criteria for CFS (concl’d):
> 4 of the following, present con-currently for > 6 mos.:- impaired memory/concentration- sore throat- tender cervical/axillary lymph nodes- myalgias- arthralgias- new headache- unrefreshing sleep- Post-exertional malaise
![Page 21: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/21.jpg)
3.Diagnostic Strategy
A. Prolonged fatigue > 1 mo., < 6 mo.- Hx and Px- Mental status, psych, neuro as indicated- Lab: CBC, lytes, urea, Cr, glucose,
Ca++, phos, ALT, ALP, protein, albumin, TSH, urinalysis, ?ESR ?Fe Sat
- Additional tests as indicated*
![Page 22: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/22.jpg)
*Additional tests as indicated:
- ANA, RF, C3, C4, CH50
- Quantitative Ig’s (serum, urine)– Cortisols, CK’s– HCV, HBV, HIV, CMV, toxo– TB skin test– Lyme serology– Sleep Study
Other cause of disease Identified?
YES: Manage as per diseaseNO:
![Page 23: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/23.jpg)
B. Chronic Fatigue > 6 mos.:
Meet the CDC criteria?
Yes: Do you really want to make this diagnosis?No: Idiopathic chronic fatigue.
![Page 24: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/24.jpg)
4. Treatment Strategies:
1. R/O diagnosable disease as per diagnostic strategy.
2. Treat psychiatric comorbidity.
3. Form therapeutic alliance with patient
4. Make restoration of function the goal of treatment
5. Provide limited reassurance
6. Cognitive Behavioral therapy?
7. Other options
![Page 25: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/25.jpg)
4. Treatment Strategies:
1. R/O diagnosable disease (diagnostic strategy)
– Try not to foster sick role
– negative findings rarely reassure these patients
– risk of iatrogenesis.
![Page 26: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/26.jpg)
4. Treatment Strategies:
2. Treat psychiatric comorbidity.
– Major depression, panic disorder
– somatic symptoms = probability of
psychiatric diagnosis
![Page 27: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/27.jpg)
4. Treatment Strategies:
3. Form therapeutic alliance with patient
– acknowledge and legitimize patient’s suffering.– discourage sick role.– reassure that you will not abandon.
![Page 28: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/28.jpg)
4. Treatment Strategies:
4. Make restoration of function the goal
– coping rather than curing
– realistic, incremental goals,
i.e. gently graduated exercise
– active rather than passive role
“not waiting to be cured” but “taking control of self-cure”
![Page 29: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/29.jpg)
4. Treatment Strategies:
5. Provide limited reassurance
– “no life-threatening illness found”
– describe “amplification” process
![Page 30: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/30.jpg)
4. Treatment Strategies: What’s the Evidence?
6. Cognitive Behavioral therapy
– Positive and negative randomized trials of varying
quality, and relatively small numbers.
– reexamines health beliefs and expectations
– explores effects of sick role and stress on symptoms
– muscle relaxation, graduated exercise, desensitization
![Page 31: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/31.jpg)

4. Treatment Strategies:
7. Other options:
– low dose SSRI’s, TCA’s: no consistent response
– modafinil (alertec): few studies
– complementary therapies. No evidence from RCT’s
![Page 35: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/35.jpg)
Depression Very common problem in primary
practice 10% of men over lifetime 20% of women over lifetime
May be even more prevalent in medical patients up to 40% with chronic illness
![Page 36: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/36.jpg)
Depression in Medicine Depression more common in
following illnesses: stroke dementia diabetes heart disease renal disease cancer
![Page 37: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/37.jpg)
Depression and Drug Tx certain drugs have been linked to onset of
depressive symptoms common offenders:
steroids, calcium channel blockers, digoxin cohort studies
withdrawal of psycho-stimulants benzos, barbituates, morphine, levo-dopa
perhaps ACEi, statins B-blockers controversial
![Page 38: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/38.jpg)
Why should we care? Prognosis of medical diseases
worse in depressed patients 15 months post onset of depression,
mortality rates are 4 times that of age matched controls!!!
Depressed patients admitted to NH are 1.5 times more likely to die within a year
![Page 39: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/39.jpg)
Post MI, depression is an important marker of prognosis as important as LV function
incidence in stroke patients very high between 25-80% range is large b/c difficult to make
diagnosis
![Page 40: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/40.jpg)
Cancer and depression
estimates vary, but expect that depressed patients have mortality rates 10-20% greater than matched counterparts
![Page 41: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/41.jpg)
Diagnosis often difficult medical patients often have somatic
complaints GI upset, headache, fatigue etc.
important to r/o other causes for complaints hypothyroid, anemia etc.
rating scales available (+ we have them!)

DSM 4 Criteria
Must have one of: depressed mood most of the time decreased interest/pleasure in nearly
all activities Plus, must have 5 of the following
during a 2 week period:
![Page 43: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/43.jpg)
DSM 4 Criteria
weight change sleep change observed agitation or retardation fatigue or loss of energy feelings of worthlessness or excessive
guilt unable to concentrate / indecisiveness recurrent thoughts of death
![Page 44: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/44.jpg)
Minor Depression patients and doctors may want to
attribute mood to current life stress I.e. adjustment disorder this is characterized as a minor
depression most common type of depression becomes problematic if leads to
social dysfunction, or persists longer than 2 months
![Page 45: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/45.jpg)
Course and Prognosis untreated major depression:
40% resolve spontaneously within 6 - 12 months
20% resolution is incomplete sub-clinical symptoms persist for years
40% depression continues depression is usually recurrent
![Page 46: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/46.jpg)
Course and Prognosis
depression is usually recurrent 70% recurrence after 2 episodes 90% recurrence after 3 episodes
thoughts of death are common 1 in 8 suicide attempts are successful risk factors for suicide:
medical illness, ETOH, male, Caucasian, presence of psychotic symptoms, social isolation, history of previous attempts, and a plan
![Page 47: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/47.jpg)
Treatment main modalities include
psychotherapy drug treatment electro-convulsant therapy
should be individualized
![Page 48: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/48.jpg)
Psychotherapy recent studies do show it to be as
effective as medication 40-50% improve BMJ 2000;320:26-30
perhaps best suited to less severe forms of depression in a highly motivated patient
![Page 49: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/49.jpg)
Medications three main groups of drugs:
SSRI TCAs MAOI
occasionally for refractive forms: lithium valproate thyroid supplementation
![Page 50: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/50.jpg)
Medications in general, need 6 week trial to see
effect try to adjust dose to achieve
benefits at lowest possible dose usually continue therapy for 6
months to 2 years relapses usually occur within 2
months of discontinuation; taper slowly
![Page 51: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/51.jpg)
SSRI Most commonly used safer in overdose than TCAs some meta-analyses say less
effective than TCAs: other say equal
fluoxetine (Prozac) safe in pregnancy
![Page 52: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/52.jpg)
SSRI - Common Side Effects GI:
nausea, diarrhea, weight gain neuro:
headache, sedation, paresthesia insomnia, poor memory, agitation
other: sexual dysfunction
![Page 53: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/53.jpg)
SSRI - Rare Side Effects Neuro:
extrapyramdal - dystonias, akathesia b/c of serotonin mediated inhibition of
dopaminergic pathways Cardiac
case reports of a fib, bradycardia, syncope
may have class 1,4 properties and be pro-arrhythmic
SIADH
![Page 54: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/54.jpg)
SSRI - Serotonin Syndrome Insidious, may be fatal
usually seen when 2 or more drugs enhance serotonin activity
present as: confused, agitated, fever, shivering,
diaphoretic, diarrhea, ataxic, hyper-reflexic, myoclonus
tx: stop meds +/- anti-sertoninergics (BB)
![Page 55: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/55.jpg)
SSRI - OD Rarely fatal
if fatal, usually b/c of what it is combined with
moderate OD - 30* dose - are nauseated, drowsy
high - 75* - may have seizures, ECG changes and further decreased LOC
supportive care mainstay of treatment

TCAs until recently, most common drugs
used to treat depression decrease use attributed to addition of
SSRI to market very effective treatment
approx. 50-60% improve may still be 1st line for severe
depression

TCAs inhibit re-uptake of mono-amines,
noradrenaline and serotonin at nerve endings
many possible side effects, especially in the elderly

TCAs - Side Effects anti-cholinergic:
dry mouth, nausea, constipation, urinary retention, mydriasis and cycloplegia
cardiovascular: postural hypotension, tachycardia
neurologic: fine tremor, dizziness, ataxia drowsiness

TCA - Overdose can be rapidly fatal were the 4th most common OD within 6 hours:
CNS depression, seizures respiratory depression CVcollapse, QRS prolongation and VT
quinidine like effects

TCA - OD - Basic Treatment symptoms develop within 1-2 hours undergoes entero-hepatic circulation
repeated activated charcoal correct acid-base - ventilator,
NaHCO3 treat hypotension arrhythmias - NaHCO3, lidocaine,
pacing seizures - benzos or dilantin

MAOI increases levels of noradrenaline,
dopamine and 5-hydroxytryptamine
usually reserved for atypical depression: weight gain excessive sleep marked anxiety / obsessional features
![Page 62: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/62.jpg)
MAOI - Side Effects common:
weight gain drowsiness, agitation postural hypotension
interactions may cause hypertension: tyramine in cheese, herring, red wines dopamine - other antidepressants
must give at least 2 week wash-out period
![Page 63: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/63.jpg)
ECT usually reserved for:
imminent suicide psychotic depression catatonia
very effective usually need 6-8 treatments over 3
weeks
![Page 64: CHRONIC FATIGUE/DEPRESSION THE MIND BODY CONNECTION](https://reader035.fdocuments.net/reader035/viewer/2022062221/568136e3550346895d9e7c7c/html5/thumbnails/64.jpg)
ECT - Side Effects can develop short-term retrograde
amnesia also can get hypertensive surge
sympathetic mediated b/c done under general
anaesthesia, other potential complications include aspiration pneumonia etc.

Special Considerations in Elderly age-related physiologic changes
may alter pharmacokinetics reduce flow to liver, kidney decreased enzyme activity
usually on multiple medications increases potential for drug
interactions “start low and go slow”

Special Considerations in Elderly TCAs metabolized by P-450
common inhibitors cipro, biaxin, flagyl, amiodarone, fluconazole
narrow therapeutic range increases possible side effects
SSRI prozac, zoloft, paxil, luvox all inhibit
P450 careful with haldol, coumadin, lithium

Conclusions depression is common in our patient
population elderly, chronic illnesses often present with somatic complaints
therapy is effective ideally managed by GP, or someone who
can see patient frequently many side-effects, but SSRI generally well
tolerated
