[Chronic fatigue syndrome in school children].

Chronic fatigue syndrome (CFS) is characterized by persistent or relapsing debilitating fatigue for at least 6 months without any apparent medical diagnosis that would explain the clinical presentation. Although, most of the reported patients are over age 30, CFS also affects school children. To better understand CFS, the network of the central nervous-endocrine-immune systems should be considered, and one must be careful to distinct CFS from school absenteeism and other psychosomatic disorders often seen among them.
