- Objectives The survival rates for patients affected by aneurysmal subarachnoid hemorrhage (aSAH) have increased in recent years; however, many patients continue to develop cognitive dysfunctions that affect their quality of life. The commonly used outcome measures often fail to identify these cognitive dysfunctions. This study aimed to evaluate the long-term outcomes at 1 and 3 years after aSAH to assess changes over time and relate outcomes to patient characteristics and events during the acute phase. Materials and Methods This prospective observational study included patients that experienced aSAH. Patients were assessed according to the extended Glasgow Outcome Scale, Life Satisfaction Questionnaire, Mayo-Portland Adaptability inventory-4, and Mental Fatigue scale. Results Patients were assessed after 1 year (n = 62) and 3 years (n = 54). At 3 years, the extended Glasgow Outcome Scale score improved in 15% and worsened in 12% of the patients. Mental fatigue was observed in 57% of the patients at 1 year. Patients <60 years of age at the time of aSAH had more self-assessed problems, including pain/headache (p < .01), than patients >60 years of age. Patients with delayed cerebral ischemia during the acute phase reported more dissatisfaction at 3 years, whereas no significant result was seen at 1 year. Conclusions Cognitive dysfunction, especially mental fatigue, is common in patients with aSAH, which affects quality of life and recovery. Patient outcome is a dynamic process developing throughout years after aSAH, involving both improvement and deterioration. This study indicates the importance of longer follow-up periods with broad outcome assessments.

- Objective Post-traumatic epilepsy (PTE) is common, but its impact on survival after traumatic brain injury (TBI) of different severity and in different demographic patient groups is unknown. We analyzed the risk of death associated with PTE with adjustment for TBI severity, causes of death, and the contribution of epilepsy as direct or contributing cause of death. Methods Register-based, retrospective cohort study. All individuals hospitalized in Sweden for a TBI between 2000 and 2010 without prior seizures were identified in the National Patient Register, with follow-up until 2017. Subsequent epilepsy was identified by ICD-10 codes. Time-dependent Cox proportional hazard ratio (HR) was used to assess hazard of death, with epilepsy as a time-updated covariate. Adjusted analyses for age, gender, injury severity and comorbidities were also performed. Causes of death were analyzed using the Cause of Death Register. Results Among 111 947 individuals with TBI, subsequent epilepsy diagnosis was associated with a crude HR of 2.3 (95% CI: 2.2-2.4) for death. Stratified analyses showed a HR of 7.8 (95% CI: 6.5-9.4) for death in younger individuals. Epilepsy was a more common underlying cause of death in younger individuals. Conclusion PTE is associated with a higher risk of death and epilepsy seems to contribute to a significant proportion of deaths, especially in younger age groups. Future studies on whether improved epilepsy treatment can reduce mortality are needed.

- Objective Satisfactory anabolic reactions, including the activation of the hypothalamic-pituitary-adrenal (HPA) axis, are essential following severe traumatic brain injury (TBI) and aneurysmal subarachnoid hemorrhage (SAH). Many factors may influence this activation. This study aimed to investigate whether individuals who reported chronic diseases, psychosocial afflictions, or stressful events before a severe brain injury display a different pattern regarding cortisol levels retrospectively and up to three months compared with those who did not report stressful experiences. Materials and Methods Fifty-five patients aged 16-68 years who were admitted to the neurointensive care unit (NICU) were included. Hair cortisol measurements offer a unique opportunity to monitor cortisol levels retrospectively and after the trauma. Hair strands were collected as soon as possible after admission to the NICU and every month until three months after the injury/insult. The participants/relatives were asked about stressful events, psychosocial afflictions and recent and chronic diseases. Results The group who reported chronic diseases and/or stressful events before the brain injury had more than twice as high median hair cortisol levels before the brain injury compared with those who did not report stress, but the difference was not statistically significant (P = .12). Those who reported stress before the brain injury had statistically significantly lower hair cortisol values after the brain injury and they remained until three months after the injury. Conclusions Stressful events and/or chronic disease before brain injury might affect mobilization of adequate stress reactions following the trauma. However, the large variability in cortisol levels in these patients does not allow firm conclusions and more studies are needed.
