[Note: the full text of this case definition – endorsed by the IACFS/ME – is available free of charge.]
The case definition for chronic fatigue syndrome was developed for adults (Fukuda et al. 1994), and this case definition may not be appropriate for use with children and adolescents.
The lack of application of a consistent pediatric definition for this illness and the lack of a reliable instrument to assess it might lead to studies which lack sensitivity and specificity.
In this article, a case definition is presented that has been endorsed by the International Association of ME/CFS.
