Prevalence[edit | edit source]
- 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.
- 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.
