Research abstract

Considerable discussion has transpired regarding whether chronic fatigue syndrome is a distinct illness from Myalgic Encephalomyelitis.

A prior study contrasted the Myalgic Encephalomyelitis International Consensus Criteria (ME-ICC; Carruthers et al., 2011) with the Fukuda et al. (1994) CFS criteria and found that the ME-ICC identified a subset of patients with greater functional impairment and physical, mental, and cognitive problems than the larger group who met Fukuda et al. (1994) criteria (Brown et al., 2013).

The current study analyzed two discrete data sets and found that the ME-ICC identified more impaired individuals with more severe symptomatology.
