The EEG as an independent indicator of mortality and healthcare utilization

Quantitative EEG in ischemic stroke: Correlation with functional status after 6months

“…Similarly, 6 month mortality was independently associated with baseline NIHSS score, age of stroke onset, and DTABR as a marker of EEG slowing. This finding from a cerebrovascular impaired cohort are in line with results from a general population consisting of 3193 patients, 19% of which experienced a stroke, in which diffuse and focal slowing were associated with an increased mortality during a follow up period of 3.5 years (Stecker, 2009).…”

Increased mortality in patients with standard EEG findings of ‘diffuse slowing’

“…In our retrospective study of standard, 24-hour EEG reports in 1069 inpatients, we found that "diffuse slowing" on cEEG is significantly associated with mortality after an adjustment for age, sex, and CCI, confirming previous associations between diffuse slowing on EEG and mortality. (31,32) In addition, we demonstrated the association persists even when limited to awake patients only.…”
