The relationship between subjective ratings of sleep and mental functioning in healthy subjects and patients with chronic fatigue syndrome

Cognitive deficits in chronic fatigue syndrome and their relationship to psychological status, symptomatology, and everyday functioning.

Moreover, the deficits in RT were not related to sleep quality; however, it was not possible to examine whether cognitive deficits were restricted to CFS participants with a sleep disorder (as was found by Smith et al, 1996), as only four CFS participants were not classified as poor sleepers. Although high, the finding that 34% of controls were classified as poor sleepers is comparable to the 40% reported for healthy Australian adults of an equivalent age (Magee, Caputi, Iverson, & Huang, 2008).…”

Applying this measure at initial assessment (baseline) revealed data indicating that the health status for the cohort was poor; the majority of the group (41%) rating their health as 'bad with some recovery'.…”
