Unrefreshing sleep

Unrefreshing sleep is a core symptom in the diagnosis of SEID (ME/CFS).

The "Report Guide for Clinicians" by the IOM and a part of the Institute of Medicine report states: "Despite the absence of a specific objective alteration in sleep architecture, the data are strong that the complaint of unrefreshing sleep is universal among patients with ME/CFS (SEID) when questions  about  sleep  specifically  address  this  issue.  While  polysomnography  is  not required to diagnose ME/CFS (SEID), its use to screen for treatable sleep disorders when indicated is appropriate. Diagnosis of a primary sleep disorder does not rule out a diagnosis of ME/CFS (SEID)."
