Linking Emotions with Physical Symptoms




“The good physician treats the disease, but
the great physician treats the person.”

                                          William Osler
Non-Specific Symptoms
Often missed in assessment
Dualism


“If you are distressed by anything external, the pain is not due to the thing
itself, but to your estimate of it; this you have the power to revoke at any
moment”
                                                    Marcus Aurelius 180BC


Dualism         Mind / Body Divide

The “Baskerville” Effect
Is disease real or is it in the mind?
Physiological Response to Stress

Chronic stress & Acute stress

Pituitary Gland, Hypothalamus and Amygdala



Adrenal glands =        Secrete hormones
                        Epinephrine      Cortisol      Glucocorticoids


                        Heart          =       beats faster

                        Lungs          =       faster / shallow
                        Muscles        =       tense
Damage from Stress

Arterial damage

Increased glucocorticosteroids weaken immune system
                               reduce bone mass
                               reproductive suppression

Common Chronic Ill-Health Complaints

• Low Back Pain
• Carpal Tunnel Syndrome
• Cumulative Trauma Disorders             FORMS OF
• Tendonytis                              CHRONIC PAIN
• Repetitive Strain Injury                & FATIGUE
• Fibromyalgia
• Irritable Bowel Syndrome
• Chronic Fatigue

Those with heightened symptoms choose attributions to match concepts of
what is currently acceptable in medicine

External cause for illness preferred - patient becomes a helpless victim
Chronic Patient’s Attributions of Ill-Health

• Work

• Environment
    Chemicals
    Stress
    Toxins
    Virus
    Allergies

• Traumatic injury

• Anatomy / Ergonomic

Somatization and Fashionable Diagnoses

Somatoform Disorders (DSM IV category) “Somatization disorder”

Psychiatric diagnosis
Somatization             1. Rationalisation for psychosocial problems
                         2. Coping mechanism
                         3. Becomes a way of life

            Multiple Chemical Sensitivity             Dysautonomia
           Reactive Hypoglycemia           Irritable Bowel Syndrome
                          Chronic Fatigue Syndrome

1.   Vague subjective multisystem complaints
2.   Lack of objective lab findings e.g no organic cause
3.   Semi-scientific explanations e.g “post-viral syndrome”
4.   Symptoms consistent with Depression, Anxiety or general unhappiness

Psychological / Perceptual Process of Illness

Internal Processes
“Do I   notice internal changes?”
                                                   MENTAL SCHEMA
“Should   I interpret them negatively?”
                                           Internal representation of the world
   “Should I think they are important?”     (knowledge, attitudes, beliefs)


                                           What do we believe about health?
External processes
   “Do I notice external sources?”
                                           What do we believe affects health?
   “What should I believe about it?”
   “What should I do about it?”

          Little communication             Stressful environment
       Learned behaviours                      “Negative Affectivity”

Psychology important in how symptoms are perceived and reacted to
Chronic Fatigue Syndrome


• Non-specific subjective symptom

• Overlap with psychiatric diagnoses (66%)

• Chronic long-term inability and tiredness

• Both Physical and Psychological fatigue

• Most prevalent in white, middle class thirtysomething females

• Fatigue dominates activities and life
Bias – The placebo effect really does work!
Most effective medication known!
In approx. 30% of pop.
Subjected to more clinical trials than any other medicament
Nearly always does better than anticipated
The range of susceptible conditions seems limitless
Does not always occur
Present in subjective and objective outcomes
Negative outcomes can occur (Nocebo effect)

•Big pills better than smaller pills
•Red pills better than blue
                                     Patient’s “knowledge” of their treatment causes bias
•4 pills better than 2
                                     e.g. Benedetti & the Turin study
•30% of pop.
•Sham surgery vs arthroscopy for osteoarthritis
Treatment Bias of Healthcare

Behavioural Responses to Diagnoses

Hedonism

Put life in order               ADAPTIVE COPING
                                Talk about it
Premature grieving              Planning
                                Changes
Sick Role
                                MALADAPTIVE COPING
Illness Behaviour
                                Drink
                                Eat
Over-sensitivity to symptoms    Substance use

Premature death
  Hierarchy of Needs


                   Self actualisation (personal growth and fulfilment)
  GROWTH
  NEEDS                         Esteem (self and others)

                Belonging (group membership, affection, companionship)

  HOMEOSTATIC            Security (safety, stability, continuity)
  NEEDS
                            Bodily needs (food, drink, safety)




Maslow 1954
Four Pathways of Psychological Factors in Ill-Health

1)    Part of Cause of Health Condition
      e.g.    Influencing factors (personality)
              Risky behaviours


2)    Part of Health Condition
      e.g.    Stroke, Metastases


3)    Effects of Health Condition
      e.g.    Chronic ill-health        depression, anxiety, withdrawal


4)    Psychological Interventions
      e.g.  Therapeutic benefits
            Increased compliance
  Compensation Neurosis

  Pending litigation

  Treatment results often poor

  Some overt malingering

  Exaggerated illness due to:
  suggestion      +        somatization
  rationalization +        distorted sense of justice
  victim status   +        entitlement

  Adverse legal / admin. systems

  Harden patient’s convictions

  With time, care-eliciting behaviour may remain permanent
Bellamy, 1997
Compensation Neurosis

                         Improvement in health.....

                         ...may result in loss of status


Patient compelled to guard against getting better


Financial reward for illness is a powerful nocebo


Exacerbates illness


 In a litigious society, will compensation neurosis become more widespread?
Accident Neurosis

• Failure to improve with treatment until compensation issue settled

• Accident must occur in circumstances with potential for compensation
payment

• Inverse relationship to severity of injury - Accident neurosis rare in cases of
severe injury

• Low socio-economic status favors accident neurosis

• Complete recovery common following settlement of compensation issue

Secondary Gain Pre-disposition

 What is the Motivation?

• Desire for attention

• Punish spouse / others

• Solve life’s problems

• Cry for help

• Diversion from work

• Socially approved task avoidance
         sex with spouse
         work
         military duty
Secondary Gain Pre-disposition

 Non-economic motivation?


• Loneliness


• Difficulty expressing emotional pain


• Previous history of attention seeking when ill


• Depression


• Anxiety
Secondary Gain Pre-disposition

 Who are the Potential Claimants?


• Military patients nearing severance


• Workers under retirement age


• Low job satisfaction


• Workers soon to be made redundant


• Members of support groups
 Abnormal Illness Behaviour (Care Eliciting Behaviour)

 • Disability disproportionate to detectable illness
 • Constant search for disease validation
 • Relentless pursuit of “enlightened doctors”
 • Appeals to doctor’s responsibility
 • Attitude of personal vulnerability and entitlement to care by others
 • Avoidance of health roles due to lack of skills and fear of failure
 • Adoption of sick role due to rewards from family, friends, physicians
 • Behaviours which sustain the sick role - complaints, demands, threats




Blackwell, 1987
 Return to Work

  Longer off work = Less likely to return to work
                           10 20 30 40 50 60 70 80 90 100
     % returning to work




                                                            <1 2 4 6 8 10 12 14 16 18 20 22 24
Waddell, 1994                                                         months not working
Conclusion

• Somatization influenced by numerous factors

• Sick role resolves intrapsychic, interpersonal or social problems

• Fashionable diagnoses have considerable overlap

• Occupational and Environmental syndromes

• Non specific and subjective complaints

• Underlying depression, anxiety, and history of unexplained complaints

• Mass communication + support groups = fashionable way to solve distress
• Behavioural aspects of chronic patients – blame, refusal, over-reporting etc.
