Chronic fatigue syndrome: a joint paediatric-psychiatric approach

Comment in: Chronic fatigue syndrome: a joint paediatric-psychiatric approach. [Arch Dis Child. 1992]

 

Prolonged fatigue after an apparent viral infection, occurring sporadically or as an epidemic, has been described over the past 50 years. It has been given various names including Royal Free disease (1) and myalgic encephalomyelitis, but the preferred terms in the medical literature have been postviral fatigue syndrome (2) or chronic fatigue syndrome (CFS). (3)

However, the validity of this syndrome as a nosological entity has created a good deal of controversy and remains in doubt. (4) A constellation of symptoms make up the syndrome. There is fatigue of defined onset that is generally reported to follow a viral illness, often an influenza-like illness or an infection of the upper respiratory tract. The patient experiences profound fatigue with the initial illness and then fails to make the expected recovery, with fatigue that can persist over months or years. Fatigue is defined as a subjective sensation, which the patient often describes as tiredness or weariness and that occurs at rest. These patients also report a clear relationship of fatigue to activity. The term fatiguability has been used to describe the greater than normal fatigue that occurs after physical and sometimes after mental exertion in these patients. A great variety of associated symptoms have been described that include increased sleepiness, dizziness, vertigo, headache, difficulty in concentrating, sore throat, muscle weakness, and myalgia. The majority of patients have some emotional symptoms. There can be irritability and anxiety, tearfulness and depression. The fatigue and associated symptoms are of such severity as to impair significantly normal daily activities. There is a remarkable absence of physical signs and physical investigations fail to detect any organic pathology or current infection to account for the symptoms.

Intense fatigue in humans. Psychosocial and cultural aspects

Abstract:

A differentiation between the normal sensation of tiredness and the symptom “fatigue” is often difficult. Both are influenced by cultural, social, psychological and biological factors, which can lead–interactively–to symptom formation. Psychiatric disorders frequently associated with fatigue are all forms of depression, somatization and anxiety disorders, chronic pain states and drug abuse among many others. In at least 2/3 of patients with the fashionable chronic fatigue syndrome–formerly called neurasthenia–a psychiatric diagnosis can be made, most of them also suffer from many symptoms attributes to the autonomous nervous system. The clinical approach should be cautious avoiding diagnostic and therapeutic overaction and therapy should emerge from a diagnosis properly assessed.

Myalgic encephalomyelitis

Note: This letter appeared in the Journal of the Royal Society of Medicine in March 1990.

 

We accept that Martin Lev (November 1989 JRSM, p 693) is correct to point out that the anxiety and depression noted in patients labelled as suffering from ‘ME’ are the consequence of ‘underlying organic processes’. The demonstration of hyperventilation in the overwhelming majority of these patients (Rosen SD, King JC, Nixon PGF, unpublished results), provides a clear metabolic reason for the anxiety (1-3). ‘Depression’ is a predictable reaction to the inability to make and sustain effort due in part to the ease of acidosis of muscle cells depleted of buffer base reserves(4).

We agree with Sargant(5), that the sufferers from the late stages of effort syndrome, who have nothing to gain from their ill health and much to lose, are among the most gifted and energetic of people, and consequently the most upset about the frustration caused by loss of performance.

Neurasthenia in the 1980s: chronic mononucleosis, chronic fatigue syndrome, and anxiety and depressive disorders

Abstract:

In the 1980s, patients suffering from unexplained fatigue and what seemed like a prolonged attack of acute mononucleosis were given the diagnosis of chronic mononucleosis or chronic infection with the Epstein-Barr virus.

Although the diagnosis has great appeal, the Epstein-Barr virus does not cause the syndrome (CFS) of chronic fatigue, which has been renamed and redefined chronic fatigue syndrome to remove the inference that the virus is its cause.

From a historical perspective, both syndromes represent the 1980s equivalent of neurasthenia, a disease of fatigue that influenced the development of psychiatric nosology. Because patients with depression and anxiety also have chronic fatigue and because most patients with CFS have an affective disorder, the assessment of organic causes of this syndrome requires careful psychiatric diagnosis and treatment.

Defining chronic fatigue syndrome as a medical disorder may deprive patients of competent treatment of their affective disorder.
