Jun 27, 2019 · Patients who are brain-injured and unresponsive may appear unconscious, but a study published Wednesday in the New England Journal of Medicine repurposed a widely-used technology to demonstrate...

Coma is defined as ‘an eyes-closed state of unresponsiveness with severely impaired arousal and cognition’. 17 In comatose patients the EEG can be used to assess for evidence of potentially reversible causes, such as intoxication with sedatives, NCS, and NCSE.

The EEG allows insight into thalamocortical function in comatose patients when this is inaccessible clinically. A single EEG can help with broad diagnostic categorization whereas continuous or serial EEG provides monitoring for unstable and potentially treatable conditions and for monitoring the eff …

To test the value of quantifiable electrical stimuli as a reliable method to assess electroencephalogram reactivity (EEG-R) for the early prognostication of outcome in comatose patients.

Aug 26, 2020 · EEG involves recording the brain activity at rest and testing EEG reactivity (EEG-R) to external stimuli. This EEG phenomenon relies upon the integrity of the associated sensory receptors and afferent neural pathway to the brainstem, and relay in the thalamus to the cortex.

Sep 18, 2015 · The assessment of thalamocortical function in comatose patients in the intensive care unit (ICU) can be difficult to determine. Since the electroencephalogram (EEG) affords such assessment, we have developed an EEG classification for comatose patients in our general ICU.

Differential diagnostic considerations for comatose patients with a normal EEG pattern may include locked-in syndrome, catatonia, or psychogenic unresponsiveness.

Electroencephalography (EEG) has long been used in evaluating comatose patients, and is being increasingly found to uncover patterns of prognostic significance, reveal subclinical seizure activity and provide data during treatment in which patients are paralyzed.

Spindle coma is an electroclinical entity that has been used to describe an EEG pattern of “sleep-like” activity in comatose patients. Although it has been associated with favourable prognosis, its aetiology is one of the key factors for patient outcome.

This paper discusses the various EEG features seen in coma, ranging from intermittent rhythmic delta activity to electrocerebral inactivity. A discussion regarding etiology and prognosis is presented after the EEG pattern is described in detail.
