Dyscalculia ICD-10 F81.2 R48.8

Dyscalculia is the medical term for experiencing severe difficulty in making mathematical calculations, for instance struggling to add up numbers or making more mistakes in math than in the past.[1][2] Dyscalculia is the result of a physical brain condition.[2] Dyscalculia is a cognitive symptom and is more common in people with severe M.E.[3]

Presentation[edit | edit source]

Dyscalculia in ME/CFS and Fibromyalgia[edit | edit source]

People with chronic fatigue syndrome were found to have difficulty even when adding up single digit numbers, a poor working memory and information processing contributed to the difficulties with numbers.[1] Dyscalculia in ME/CFS is more severe than that found in depression, and occurs in people with ME/CFS who do not have depression.[1]ME/CFS and fibromyalgia patients report having trouble with arithmetic.

Prevalence[edit | edit source]

  • 1995, Katrina Berne, PhD, reported a prevalence of 75-80% for 'aphasia' (inability to find the right word, saying the wrong word) and/or dyscalculia (difficulty with numbers) - although she notes that this symptom is probably underreported and more prevalent than indicated.[4]
  • 2001, In a Belgian study, 71.6% of patients meeting the Fukuda criteria and 75.1% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported a difficulty with calculations.[5]

International Classification of Diseases (ICD) - A system of medical diagnostic codes, created by the World Health Organization (WHO), to classify diseases and other health related conditions for the purpose of international diagnostic consistency. By having common diagnostic codes around the world, health researchers are better able to quantify and track disease burdens. The most current version is called ICD-11. (Learn more: www.who.int)
