Abstract
Cognitive impairments are among the most frequently
reported and least investigated components of the chronic
fatigue syndrome (CFS). As part of a multifaceted study
of the CFS, the present study investigated the cognitive
functioning of chronic fatigue patients. The performance
of 20 CFS patients was compared to that of controls (N
= 20) on 4 tests of working memory (WM). Digit Span Forward
was used to assess the storage capacity of WM. Multiple
aspects of central executive functioning were assessed
using several standard measures: Digit Span Backward, and
Trails A and Trails B. More recently developed measures
of WM were used to assess control of processing under temporal
demands (working memory task) and resistance to interference
(a sustained attention task). Deficits were restricted
to more demanding tasks, requiring resistance to interference
and efficient switching between processing routines. The
overall results clearly implicate deficits in the control
aspects of central executive function in CFS. (JINS,
