organizing, inhibition of behavior,
error detection, insight)
Attention (focus on specific stimuli
to the relative exclusion of others)

recognition)
Working Memory (temporary
storage and management of
information)

Qualitative Studies in FMS



Arnold et al. (2008) conducted a qualitative analysis of 48
FMS patients across the U.S.
Substantial negative impact on social and occupational
functioning
Disrupted relationships, social isolation, reduced leisure
activities, avoidance of physical activity, and career loss or
inability to advance in career/education

Education and Counseling 73: 114-120.
Qualitative Studies in FMS
Physical Domain
Pain
Fatigue
Disturbed sleep
Emotional/Cognitive Domains
Depression, anxiety
Cognitive impairment (decreased concentration, disorganization)
Memory problems
Social Domain
Disrupted family relationships
Social isolation
Disrupted relationships with friends
Work/Activity Domains
Reduced activities of daily living
Reduced leisure activities/avoidance of physical activity
Loss of career/inability to advance in career or education

Qualitative Studies in FMS




Greatest impact on quality of life included pain, sleep
disturbance, fatigue, depression, anxiety, and cognitive
impairment
Primary reported cognitive effects were on memory, thought
processes, planning/organization, response time, word-finding
and concentration
These impairments have collectively been referred to by
patients as “fibro fog”
“Fibro fog” is reported to affect a wide range of activities
including driving, social interactions, and work-related tasks

Qualitative Studies in FMS



Katz et al. (2004) investigated prevalence of reported
cognitive difficulties in 57 patients with rheumatic disease
with FMS and 57 patients without FMS
Compared to the non-FMS sample, FMS patients more
frequently reported memory decline, mental confusion, and
speech difficulty
Memory decline and mental confusion were coupled more
often in FMS patients
FMS patients were found to be at considerably higher risk
for cognitive difficulty

Qualitative Studies in CFIDS



Afari & Buchwald (2003) suggest that cognitive
problems are some of the most disruptive and
debilitating symptoms reported in patients with CFS
85% of patients describe impairments in attention,
concentration, and memory function
In CFS these are known as “Brain Fog”
Afari, N., Buchwald, D. (2003). Chronic Fatigue Syndrome: A Review. American Journal of Psychiatry 160: 221-236.
Qualitative Studies in CFIDS


Capuron et al. (2006) conducted a meta-analysis
showing that 50-85% of patients with CFS report
cognitive difficulties that contribute significantly to
social and occupational dysfunction
Cognitive dysfunction manifests primarily in the form
of concentration/attention problems, memory
impairment, poor word-finding ability, decreased
processing speed, motor slowing, and mental
exhaustion
Capuron, L., Welberg, L., Heim, C., Wagner, D., Solomon, L., Papanicolaou, D., Craddock, R., Miller, A., Reeves, W. (2006). Cognitive dysfunction
relates to subjective report of mental fatigue in patients with chronic fatigue syndrome. Neuropsychopharmacology 31:1777-1784.
Summary of Findings



Patients with FMS and CFS report a number of
cognitive impairments referred to as “Fibro Fog”
and “Brain Fog” respectively
These impairments include attention, memory,
executive function, processing speed, and speech
These problems have a negative impact on daily
function including driving, social interactions, and
work tasks

Quantitative Studies in FMS






Suhr (2003) studied neuropsychological test performance on
28 FMS patients, 27 chronic pain patients, and 21 healthy
controls
Measures included depression, pain, fatigue, subjective
cognitive complaints, memory, executive functioning, intellect,
attention, and psychomotor speed
FMS patients had more memory complaints, reported greater
fatigue, pain, and depression than other groups
Groups were not found to be different on testing after
controlling for fatigue, pain, and depression
Depression related to memory performance
Fatigue related to psychomotor speed

Hoover (2006) investigated neuropsychological
performance of 61 women with FMS that were age and
education-matched to 63 healthy women
FMS patients were found to have significantly poorer
performance on some measures of executive function,
working memory, and sustained attention
Neuropsychological measures were not found to be more
significant predictors of group membership than were
measures of symptoms relevant to FMS

Quantitative Studies in CFIDS





Metzger et al. (2002) conducted a study examining
discrepancies between perceived and actual performance by
40 CFS patients and 40 age and education matched healthy
controls
Performance was compared on a measure of executive
function
After correcting for differences between groups for
depression, there were no differences found in actual
performance on the test
CFS patients were found to consistently underestimate their
performance relative to normal performance
Performance correlated with patient’s ratings of mental effort
and fatigue

Quantitative Studies in CFIDS



Majer et al. (2008) examined 58 CFS patients and
104 healthy controls on neuropsychological
performance
Controlled for major psychiatric disorders and
medications known to affect cognition
CFS patients were found to have significantly higher
levels of impairment on tasks involving motor speed
and working memory
Majer, M., Welberg, L., Capuron, L., Miller, A., Pagnoni, G., Reeves, W. (2008). Neuropsychological performance in persons with Chronic Fatigue
Syndrome: Results from a population-based study. Psychosomatic Medicine 70: 829-836.
Summary of Findings



Many studies have found FMS and CFS patients
exhibit deficits on neuropsychological testing
Areas of impairment included sustained attention,
working memory, processing speed, and executive
function
After controlling for factors such as pain,
depression, and fatigue, performance was similar to
that of healthy people
Possible Biological Explanations





cortisol levels
hippocampus is responsible for
memory function
FMS patients have lower
salivary-free cortisol levels
very low and very high cortisol
levels affect hippocampal
function
selective effects on verbal
declarative memory, selective
attention, and divided attention
Sephton, S., Studts, J., Hoover, K., Weissbecker, I., Lynch, G., Ho, I., McGuffin, S., Salmon, P. (2003). Biological and psychological factors
associated with memory function in Fibromylagia Syndrome. Health Psychology 22(6): 592-597.
Possible Biological Explanations





anti-68/48 kDa protein antibodies
more common in both CFS (13.2%)
and FMS (15.6%) patients (Nishikai,
et al., 2001)
suggests related immunological
background
patients with antibodies presented
more frequently with hypersomnia,
short-term amnesia, and difficulty in
concentration
may be used as a possible marker
for fatigue and cognitive problems
Nishikai, S. ,Tomomatsu, S., Hankins, R., Takagi, S., Miyachi, K., Kosaka, S., Akiya, K. (2001). Autoantibodies to a 68/48 kDa protein in chronic
fatigue syndrome and primary fibromyalgia: a possible marker for hypersomnia and cognitive disorders. Rheumatology 40: 806-810.
Possible Biological Explanations






pain factors
pain has been shown to correlate highly
with processing speed, working memory,
free recall, and recognition memory
(Park, et al. 2001)
pain and weakened immunity is
associated with increased inflammatory
cytokines
inflammatory cytokines affect appetite,
sleep, and fatigue levels
pain affects serotonin and
norepinephrine
pain medications (particularly opiates)
have well-known effects on cognitive
function
Park, D., Glass, J., Minear, M., Crofford, L. (2001). Cognitive function in fibromyalgia patients. Arthritis & Rheumatism 44(9): 2125-2133.
Possible Psychological Explanations




clinical depression
20% of FMS patients in one
sample reported clinical levels
of depression (Sephton et al.,
2003)
correlated with immediate and
delayed verbal memory
performance in FMS
depression in FMS and CFS may
also affect domains such as
processing speed and attention
Sephton, S., Studts, J., Hoover, K., Weissbecker, I., Lynch, G., Ho, I., McGuffin, S., Salmon, P. (2003). Biological and psychological factors
associated with memory function in Fibromylagia Syndrome. Health Psychology 22(6): 592-597.
Coping With Cognitive Challenges
The focus should be on addressing
the “whole” person, not just the
individual symptoms of FMS/CFIDS.

E.T.P.S.
Developing Compensatory Strategies
Developing and implementing
compensatory strategies should
increase function and not simply
provide “symptom relief.”
Compensating Through Use of Technology




computer-assisted cognitive rehabilitation using computer
games (e.g. BrainAge™ and HAPPYneuron™) to address
processing speed, memory, and attention
PDAs and Smartphones to address memory and executive
function/organizational skills
Pulse Smartpens™ to assist with memory and executive
functioning
Speech recognition software (e.g. Dragon™) to address
fatigue related to writing and note taking
Compensating Through Lifestyle Change




diet/nutritional changes (avoid aspartame, MSG,
caffeine, simple carbohydrates, yeast, gluten, dairy,
nightshade plants)
regular exercise (low to moderate intensity aerobic
exercise at least 2x/week with strength training)
maintain a regular, consistent, paced routine
(sleep/wake, meals, rest breaks)
stress reduction (relaxation, prayer/meditation,
diaphragmatic breathing)
Compensating Through Environmental Change






avoid cold and/or damp environments
avoid exposure to strong odors
create rest environments void of distractions (e.g.
silence cell phone, turn off computer etc.)
follow principles of sleep hygiene (e.g. bedtime rituals,
bed for sleep/sex only, get up after 20 min. of
unsuccessful sleep, etc.)
avoid overheating
reduce exposure to fluorescent lighting
