Attention deficit/decreased attention span is one of the symptoms of the cognitive dysfunction associated with ME/CFS.

Presentation[edit | edit source]

Prevalence[edit | edit source]

  • In a 2001 Belgian study, 93.0% of patients meeting the Fukuda criteria and 95.9% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported attention deficit.[1]
  • Katrina Berne, PhD, reports a prevalence of 70-100% for concentration/attention deficit.[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 concentration can be used to help form a diagnosis.[4]
  • In the Holmes criteria, inability to concentrate is an optional criteria for diagnosis, under the section Minor Symptom Criteria - Neuropsychologic Complaints.[5]
  • In the IACFS/ME Primer for Clinical Practitioners (2014), decreased attention span is listed in the cognitive symptoms.[6]

Notable studies[edit | edit source]

  • 2006, Cognitive dysfunction relates to subjective report of mental fatigue in patients with chronic fatigue syndrome

    "CFS patients with significant complaints of mental fatigue (score of mental fatigue 2 standard deviations above the mean of nonfatigued subjects) exhibited significant impairment in the spatial working memory and sustained attention (rapid visual information processing) tasks when compared to CFS patients with low complaints of mental fatigue and nonfatigued subjects. In CFS patients with significant mental fatigue, sustained attention performance was impaired only in the final stages of the test, indicating greater cognitive fatigability in these patients."[7]

myalgic encephalomyelitis (M.E.) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
