Reversed or chaotic diurnal sleep rhythms
Many patients with ME/CFS end up with circadian abnormalities ranging from severe delayed sleep phase to non 24 hour circadian rhythm disorder to apparent loss of regular circadian rhythms.
Canadian Consensus Criteria[edit | edit source]
The Canadian Consensus Criteria (CCC) for ME/CFS states that some form of sleep dysfunction will be present in almost all ME/CFS patients, and includes sleep dysfunction not caused by sleep apnea as a diagnostic criteria.[1] "Reversed or chaotic diurnal sleep rhythms" are examples of sleep dysfunction involving circadian rhythm disruption, and are listed as a possible manifestation of sleep dysfunction in the Canadian Consensus Criteria for ME/CFS.[1] At least one form of sleep dysfunction is required for diagnosis according to the Canadian Consensus Criteria.
