RESUMEN
OBJECTIVES: Examine the incidence and predictors of PTSD symptoms in a cohort of patients with ICH. PATIENTS AND METHODS: This study uses a prospective cohort of 108 patients with complete follow-up data including a questionnaire regarding stress symptoms (PCL-S: PTSD checklist specific for a stressor) at 3, 6, and 12 months. RESULTS: The incidence of novel stress symptoms following ICH was approximately 6.5%. Age was negatively associated with PTSD symptoms with only trend-level significance (3 months: OR = 0.83, p = 0.087; 6 months: OR = 0.70, p = 0.015; 12 months: OR = 0.88, p = 0.087). Gender did not affect PTSD symptom development, (t = 1.34, p = 0.18). Pre-morbid functioning, initial stroke prognosis, total number of complications, and length of hospital/ICU stay were not associated with PTSD symptoms; however, each was significantly correlated with poorer functional outcomes. Yet, poorer functional outcomes were observed in those with higher reports of PTSD symptoms (r = 0.24, p = 0.01). CONCLUSION: Functional outcomes in ICH are correlated with PTSD symptoms, however the mechanism and relationship are difficult to elucidate. Further research is needed to determine possible mechanisms by which a stroke patient may develop PTSD.

BACKGROUND: It is unknown whether postanoxic cortical and subcortical myoclonus are distinct entities with different prognoses. METHODS: In this retrospective cohort study of 604 adult survivors of cardiac arrest over 8.5 years, we identified 111 (18%) patients with myoclonus. Basic demographics and clinical characteristics of myoclonus were collected. EEG reports, and, when available, raw video EEG, were reviewed, and all findings adjudicated by 3 authors blinded to outcomes. Myoclonus was classified as cortical if there was a preceding, time-locked electrographic correlate and otherwise as subcortical. Outcome at discharge was determined using Cerebral Performance Category. RESULTS: Patients with myoclonus had longer arrests with less favorable characteristics compared to patients without myoclonus. Cortical myoclonus occurred twice as often as subcortical myoclonus (59% vs 23%, respectively). Clinical characteristics during hospitalization did not distinguish the two. Rates of electrographic seizures were higher in patients with cortical myoclonus (43%, vs 8% with subcortical). Survival to discharge was worse for patients with myoclonus compared to those without (26% vs 39%, respectively), but did not differ between subcortical and cortical myoclonus (24% and 26%, respectively). Patients with cortical myoclonus were more likely to be discharged in a comatose state than those with subcortical myoclonus (82% vs 33%, respectively). Among survivors, good functional outcome at discharge was equally possible between those with cortical and subcortical myoclonus (12% and 16%, respectively). CONCLUSIONS: Cortical and subcortical myoclonus are seen in every sixth patient with cardiac arrest and cannot be distinguished using clinical criteria. Either condition may have good functional outcomes.
