Before
we begin our discussion of how to live well with Chronic Fatigue
Syndrome (CFS) and
fibromyalgia, this chapter and the next offer an overview of the two
illnesses, focusing on symptoms, diagnosis, treatments and prognosis.
This chapter discusses CFS, the next chapter FM.
Brief
Description of CFS
Chronic
Fatigue Syndrome, also known by other names such as Chronic Fatigue
and Immune Dysfunction Syndrome (CFIDS) and
myalgic encephalomyelitis (ME), is a long-term disorder affecting the
brain and other systems. Debilitating fatigue is usually the most
prominent symptom. Other common symptoms include poor sleep, body pain
and mental confusion (“brain fog”). Emotional problems such as
depression, anxiety, irritability and grief, are common.
As
a severe, long-term illness, CFS affects
many parts of patients’ lives, creating many challenges and
requiring many adjustments. Patients must struggle to control their
symptoms and adapt their lives to the limits imposed by their illness.
Adaptations may include reducing or eliminating paid work, reducing
family responsibilities, coping with increased stress and intense
emotions, and coming to terms with loss.
The
severity of CFS varies greatly. While some patients continue to lead
relatively active lives, others are housebound or even bedridden. The
average case of CFS creates moderate to severe symptoms and reduces a
person’s activity level by 50% to 75%.
Symptoms
People
with CFS usually experience several or even many symptoms.
(CFS symptom lists can be several dozen items long.) The severity of
symptoms often waxes and wanes. One symptom may be the most prominent
at one time, another in a later period. The four most common symptoms
are fatigue, pain, poor sleep and cognitive problems.
Fatigue
Fatigue is
experienced as a deep exhaustion that can be brought on by low levels
of activity or for no apparent reason. Fatigue is often
disproportional to the energy expended and lasts far longer than it
would in a healthy person (“post-exertional malaise”). Fatigue can
be intensified by a number of factors, including overactivity, poor
sleep, deconditioning, stress, emotions and poor nutrition.
Pain
Pain may
be experienced in the joints or, more commonly, as an overall body
pain that is often described with metaphors such as feeling run over
by a truck. Pain may be intensified by overactivity, non-restorative
sleep, anxiety and stress, and changes in the weather.
Poor
Sleep
Sleep
is often experienced as not restorative or refreshing. Patients often
feel as tired when they get up as before going to bed. Sleep problems
are usually a part of the illness, but they may be intensified by
other factors such as stress, overactivity, and the absence of a good
sleep environment
or good sleep habits.
Cognitive
Problems
Most
CFS patients experience cognitive difficulties, often called “brain
fog.” Cognitive problems include
feeling confused, difficulty concentrating, fumbling for words and
lapses in short-term memory. Brain fog can
be reduced by limiting activity, getting adequate rest, managing
stress and limiting sensory input.
Other
Symptoms
Patients
often experience other symptoms as well, which create further
discomfort. Common
additional symptoms include: headaches, low-grade fevers, sore throat,
tender lymph nodes, anxiety and depression, ringing in the ears,
dizziness, abdominal pain (gas, bloating, periods of diarrhea and/or
constipation), allergies and rashes, sensitivity to light and sound,
abnormal temperature sensations such as chills or night sweats, weight
changes and intolerance of alcohol.
Who
Gets CFS?
CFS is a common illness. Research suggests that there are
probably 800,000 or more adults with CFS in the United
States. In addition, children and adolescents also suffer from CFS.
Research has disproved the earlier idea of CFS as the “yuppie
flu.” The illness affects all racial and economic groups, striking
vulnerable populations more frequently than upper middle class whites.
About two thirds of patients are women.
Diagnosis
Since
there is as yet no diagnostic test
for identifying CFS or proven physical marker for the illness,
diagnosing CFS can be difficult. Severe fatigue and other symptoms of
CFS can be caused by several different illnesses. The illness is most
often diagnosed in the United States using criteria developed in 1994
by an international consensus committee organized by the US Centers
for Disease Control (CDC).
Using their guidelines, CFS is diagnosed in a two-step process. First,
a thorough medical examination and laboratory testing are used to
exclude other illnesses that have similar symptoms. These illnesses
include thyroid problems, anemia, Lyme disease, lupus, MS, hepatitis,
sleep disorders and depression. The doctor should also consider the
possibility that CFS symptoms, especially fatigue and cognitive
problems, are side effects of one or more medications taken for
another condition. Second, if other illnesses have been excluded, a
patient is considered to have CFS if two further criteria are met:
 |
The
patient has experienced at least several months of a new,
debilitating fatigue that forces a substantial reduction of
activity.
|
 |
The
patient reports four or more of the following eight symptoms: |
1.
Impaired memory
or concentration (mental confusion).
2.
Sore throat
3.
Tender lymph
nodes in the neck or armpit
4.
Muscle pain
5.
Joint pain
without redness or swelling
6.
Headaches of a
new or different type
7.
Non-restorative
sleep
8.
Extreme fatigue
following activity (“post-exertional malaise”)
A
more recent Canadian definition emphasizes five symptoms: fatigue,
post-exertional malaise, disturbed sleep, pain and cognitive problems.
It
is important to note that the presence of CFS does not exclude a
person’s having other illnesses as well. A majority of people with
CFS also have fibromyalgia. Other illnesses often found in people with
CFS include: irritable bowel syndrome (IBS), candida (yeast
infection), food and chemical allergies, depression, and sleep
disorders such as apnea and restless legs syndrome.
Causes
The
cause of CFS is
unknown. Some believe that it is caused by an agent entering the body,
while others think it is due to the body’s response, possibly to
various agents. Since CFS can appear both in clusters and in
individual cases, and because it manifests with a wide variety of
symptoms and in a wide range of severities, some researchers suggest
that CFS may prove to be several or even many illnesses. Whether it is
one or more illnesses will be decided by future research.
Treatments
Given
the lack of understanding of the cause and the absence of a cure,
treatment for CFS focuses
on controlling symptoms and improving quality of life. Medical
treatment is tailored to the individual patient, often focusing on
addressing the most bothersome symptoms such as sleep disorders and
pain. Since no medication is commonly helpful, there is often a period
of experimentation to find what works for a given individual.
Medications may have to be changed periodically, as they can lose
effectiveness. Patients are usually started with very low dosages.
Many
CFS authorities recommend the approach we will adopt in this book:
making use of medical treatments where appropriate, but focusing on
lifestyle adjustments such as pacing, controlling stress and getting
good support. Self-management techniques are often the most potent
strategies for treating CFS and fibromyalgia. CFS/FM physician Dr.
Charles Lapp summarizes
this view when he states, “There is no drug, no potion, no
supplement, herb or diet that even competes with lifestyle change for
the treatment of CFS or FM.”
Fatigue
The
principle and probably most effective technique for controlling
fatigue is
adjusting one’s activity level to the limits imposed by CFS, which
we call “living within the energy envelope.” (See Chapter
9.)
Living within limits includes strategies such as setting priorities,
taking regular rests, having short activity periods, living by a
schedule, and managing special events like vacations and holidays.
Fatigue
can also be lessened by addressing pain and poor sleep, both of which
intensify fatigue. Fatigue has additional causes as well, such as
stress, emotions, deconditioning and poor nutrition. Stress
management, exercise and healthy eating can help reduce fatigue by
addressing these causes.
Pain
Just
as with fatigue, pain is
a reflection of the limits imposed by illness, so pacing is usually
helpful. Recognizing activity
limits and staying within them, having short activity periods,
switching from task to task and taking rest breaks all reduce pain.
Also, addressing fatigue and poor sleep can reduce pain. When
we feel tired, we experience pain more intensely, so reducing fatigue
also reduces pain. Similarly, poor sleep intensifies pain, so
improving sleep is also a way to control pain.
Some
pain relief may also be achieved through medications: non-prescription
products such as aspirin and other over-the-counter pain relievers,
prescription pain relievers such as Ultram (Tramadol)
and in some cases narcotics, prescription medications intended
primarily for sleep, and anti-depressants such as Elavil
(Amitriptyline), Prozac and
Paxil.
Sleep
Sleep
can often be improved through maintaining good sleep habits and by
having an environment conducive to good sleep. Sleep-related habits
include keeping regular times for going to bed and getting up,
limiting daytime napping, avoiding caffeine and other stimulants
before bedtime, and practicing relaxation to fall asleep. A good sleep environment
includes the absence of noise, a good bed and an appropriate
temperature. Reducing pain through exercise or a bath and dealing with
worry can also help improve sleep.
Medications
commonly used to treat sleep problems include over the counter
products like melatonin and valerian, antihistamines such as Benadryl,
clonazepam (Klonopin), tricyclic antidepressants such as amitriptyline (Elavil),
benzodiazepines such as Halcion, and the hypnotic drug Ambien. Often,
a combination of two drugs is prescribed, one to initiate sleep and
another to maintain sleep.
Cognitive
Problems
As
with other symptoms, brain fog is addressed most effectively using a
combination of approaches. Strategies that are generally helpful for
CFS, such as pacing and stress management, also help control brain
fog. Other techniques that patients often use to control fog include
getting good sleep, limiting sensory input, using lists and other
reminders, having daily and weekly routines, and keeping an orderly
physical environment.
For
more on treatment options for these four symptoms, see Chapter
8.
Stress,
Emotions, Support & Loss
As
mentioned earlier, CFS has comprehensive effects, touching many parts
of patients’ lives and creating additional challenges beyond dealing
with symptoms. A treatment plan should address, in addition to symptom
management, issues such as managing stress and emotions, strengthening
support systems and coming to terms with loss. Dealing successfully
with these additional challenges usually reduces symptoms, so is also
a form of symptom management. For more on stress, emotions, support
and loss, see Chapters 13 to 16.
Prognosis
There is
so far no cure for CFS and its course varies greatly. Some patients,
probably only a small percentage, recover. They are able to resume
their pre-illness lives with only a minor residue from the illness,
such as vulnerability to high levels of stress or less physical
stamina. Another, larger group achieves notable improvement, but less
than full recovery. The amount of improvement in this second group
ranges widely. The total of these two groups might be something like
half or perhaps somewhat more than half of all patients.
Unfortunately, others remain quite ill while a few worsen over time.
The
course of CFS also varies. Some people with CFS make relatively steady
progress, some swing between periods of improvement and times of
intense symptoms, while still others have a relatively stable level of
symptoms, neither improving nor declining.
Our
program is based on the belief that most patients can find things to
help them feel better. These strategies are not aimed at curing CFS,
but they can help reduce
pain and discomfort, bring greater stability and lessen suffering.
