RT Journal Article SR Electronic T1 099 A retrospective study of mortality rates in a video-EEG telemetry patient cohort JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP e30 OP e30 DO 10.1136/jnnp-2019-ABN-2.100 VO 90 IS 12 A1 Farhat Mirza A1 Varduhi Cahill A1 Paul Cooper A1 Rajiv Mohanraj YR 2019 UL http://jnnp.bmj.com/content/90/12/e30.1.abstract AB Rationale Despite emerging evidence of altered brain connectivity patterns in patients with non-epileptic attack disorder (NEAD), studies on the mortality rates in these patients remain scarce.Methods Mortality data was studied retrospectively in a cohort of patients admitted for video-telemetry evaluation at the Manchester Centre for Clinical Neurosciences from 2009 to 2019. The diagnosis of NEAD, epilepsy or both was confirmed by the consensus opinion of experienced epileptologists. Mortality and cause of death were identified from the death alert system linked to the Electronic Patient Record and from coroners’ reports, where available.Results Out of 693 patients 662 were included in the study analyses. Death was registered in 23 patients, 82.6% of whom suffered with epilepsy and 17.4% with NEAD. In epilepsy patients, sudden unexpected death was recorded in 42.1%, death from other medical conditions in 52.6% and death from external causes - in 5.3%. In the NEAD group, the causes of death included iatrogenic and other medical conditions.Conclusions Mortality rates in the NEAD group of patients are not negligible. With NEAD patients being at risk of unnecessary iatrogenic interventions, increased awareness of the heightened mortality rates in this patient cohort could avert preventable deaths.
