“…There was no relationship between the favorable or unfavorable prognosis and the type of etiological factor, whether acute or remote. Studies with different samples associate greater severity and mortality to the underlying cause of NCSE in the elderly [9,10,11,23], similarly to what has been found in adults [7,[25][26][27].…”

“…In the Cox regression multivariate analysis, the EEG data did not remain in the equation to predict the risk of death. Some studies describe that the presence of LPD has a worse outcome, regardless of etiology, in the elderly [24] and in adults with NCSE [27]. Despite the importance of the EEG in the diagnosis and follow-up of patients with NCSE, the predictive significance of the EEG aspects is still not fully known [19,20,24,25,28,29].…”

To assess the clinical-EEG aspects, characterization of subtypes, relationships with prognostic scales and the occurrence of death in elderly patients in the acute phase of nonconvulsive status epilepticus (NCSE).Methodology Clinical variables, EEG data, Status epilepticus severity score (STESS), and the Epidemiologybased mortality score in status epilepticus (EMSE) were related to the death of 96 patients who were over 60 years old, with NCSE.Results NCSE with coma was observed in 31 patients (19 non-subtle and 12 "subtle" SE) and focal NCSE with impairment of consciousness in 65 cases. There were no significant EEG differences according to the type of NCSE. Higher STESS scores occurred in the comatose NCSE patients when compared to those with focal NCSE and impairment of consciousness (4.8 ± 1.2 vs 3.7 ± 1.2; T-Test; p<0.001). It was observed that 25 (26%) elderly died, with a mean survival time of 19.3 days. Elderly people with a higher risk of death are those diagnosed with

Background/Objectives: Cardiac arrest may cause significant hypoxic–ischemic injury leading to coma, seizures, myoclonic jerks, or status epilepticus. Mortality is high, but accurate prognostication is challenging. A multimodal approach is employed, in which electroencephalography (EEG) forms a key part with several recognised patterns of prognostic significance. Methods: In this retrospective study, clinical and qualitative features of the EEG of patients admitted to the Intensive Care Unit (ICU) at Kingston General Hospital following cardiac arrest from 2017 to 2020 were reviewed. The study included 81 adult patients (≥18 years). Outcome was assessed using the Cerebral Performance Category (CPC) as 1–2 (favourable) or 3–5 (unfavourable). EEG patterns were divided into groups within the highly malignant, malignant and benign patterns described in the literature. Results: There were a wide range of causes and 22% had a favourable outcome. Highly malignant, malignant and benign patterns were associated with survival in 0%, 70% and 100%, respectively, and favourable outcomes in 0%, 48% and 100%. All patients with seizures died, and 94% with myoclonus had unfavourable outcomes. In contrast, EEG reactivity and improvement on follow-up EEG were associated with a favourable outcome. Conclusions: Highly malignant EEG, seizures and myoclonus were associated with unfavourable outcomes, while patients with malignant EEG had better outcomes.
