Memory problems in myalgic encephalomyelitis can be very disabling. Mental fatigue makes memory problems worse but does not account for all memory deficiencies in people with ME/CFS. A 2006 study by the CDC found that patients with CFS and high complaints of mental fatigue exhibited significant impairment in working memory.
Presentation[edit | edit source]
Prevalence[edit | edit source]
- In a 2001 Belgian study, 85.6% of patients meeting the Fukuda criteria and 89.3% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported memory problems.
Symptom recognition[edit | edit source]
- In the Canadian Consensus Criteria, impairment of concentration and short-term memory consolidation is an optional criteria for diagnosis, under the section Neurological/Cognitive Manifestations.
- In the Fukuda criteria, the symptom of substantial impairment in short-term memory can be used to help form a diagnosis.
- In the Holmes criteria, forgetfulness is an optional criteria for diagnosis, under the section Minor Symptom Criteria - Neuropsychologic Complaints.

chronic fatigue syndrome (CFS) - A controversial term, invented by the U.S. Centers for Disease Control, that generally refers to a collection of symptoms as “fatigue”. There have been multiple attempts to come up with a set of diagnostic criteria to define this term, but few of those diagnostic criteria are currently in use. Previous attempts to define this term include the Fukuda criteria and the Oxford criteria. Some view the term as a useful diagnostic category for people with long-term fatigue of unexplained origin. Others view the term as a derogatory term borne out of animus towards patients. Some view the term as a synonym of myalgic encephalomyelitis, while others view myalgic encephalomyelitis as a distinct disease.
