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.[1]

Fibromyalgia patients also report having problems with memory and refer to it as fibro fog.

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.[2]

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.[3]
  • In the Fukuda criteria, the symptom of substantial impairment in short-term memory can be used to help form a diagnosis.[4]
  • In the Holmes criteria, forgetfulness is an optional criteria for diagnosis, under the section Minor Symptom Criteria - Neuropsychologic Complaints.[5]

Memory issues that begin after COVID-19 are a potential symptom of Long COVID in the World Health Organization's definition.[6]
