Abstract
Background
Close relatives (CR) of patients with severe traumatic brain injury (TBI) and high-grade subarachnoid hemorrhage (SAH) suffer extraordinary distress during the treatment: Distress may lead to persisting mental illness symptoms within the spectrum of post-traumatic stress disorder (PTSD), anxiety disorders, and depression. The primary goal of this study was to determine the prevalence and severity of these symptoms in CR. The secondary goal was identification of associated factors.
Method
Standardized interviews were conducted with 53 CR (mean age of 57.7 ± 11.4 years) of patients with TBI °III (n = 27) and high-grade SAH H&H °III–V (n = 26) between 5 and 15 months after the event. The interviews contained a battery of surveys to quantify symptoms of PTSD, anxiety disorders, and depression, i.e., Impact of Event Scale (IES-R), 36-item Short-Form General Health Survey (SF-36), and Hospital Anxiety and Depression Scale (HADS). Fixed and modifiable possibly influencing factors were correlated.
Results
Twenty-eight CR (53 %) showed IES-R scores indicating a probable diagnosis of PTSD. Twenty-five CR (47 %) showed an increased anxiety score and 18 (34 %) an increased depression score using HADS. Mean physical component summary of SF-36 was not abnormal (49.1 ± 9.1), whereas mean mental component summary was under average (41.0 ± 13.2), indicating a decreased quality of life caused by mental effects. Perception of the interaction quality with the medical staff and involvement into medical decisions correlated negatively with severity of mental illness symptoms. Evasive coping strategies were highly significantly associated with symptoms.
Conclusions
This study quantifies an extraordinarily high prevalence of mental illness symptoms in CR of patients with critical acquired brain injury due to SAH and TBI. Modifiable factors were associated with severity of mental illness symptoms. Prospective studies testing efficiency of early psychotherapeutic interventions are needed.

This paper reports the results of a single-center study investigating mental illness symptoms in close relatives of patients with severe brain injury. An extraordinarily high prevalence of mental illness symptoms in relatives of patients with critical acquired brain injury is reported, and the results of the study are in concordance with previous studies within the field of neurorehabilitation. In neurorehabilitation, it is well established that there is an association between the condition of the patient and the condition of the relative. This association changes over time as the patient regains function and the family starts adapting to the changed situation of life. Consequently, it is necessary to collect information about the status of the patient when investigating the mental condition of close relatives. At the very least, establishing the rehabilitation status of the patient at follow-up is essential. The possible outcomes after severe brain injury are diverse, ranging from death to regaining physical and cognitive functioning, consequently affecting the mental condition of the relatives. Relatives of patients within rehabilitation facilities can experience hope and optimism regarding the future, whereas relatives of patients in nursing homes might experience despair, hopelessness, and symptoms of depression, etc. The only patient-related variable the authors used was the gross outcome measure Glasgow Outcome Scale (GOS), and they were not able to find any association between the patient’s GOS at time of the interview and the mental condition of the relative. However, this is not surprising, as the GOS is a gross distinction between broad categories ranging from dead to good recovery, and even patients categories with a ‘good recovery’ can have disabilities severely affecting the daily life of the family.
Patients scoring in the higher GOS categories will very often have more subtle and invisible deficits, however such may very well be more draining for the close relative than a hemiparesis, despite the fact that a hemiparesis can cause a lower GOS score because the patient may be depending on support. The lack of information about the status of the patient along with the varying follow-up interval limits the generalizability of the study. Nevertheless, the study does contribute to the existing literature in the field and emphasizes the vulnerability of the close relatives of patients with severe brain injury. Thus the study underlines the need for prospective studies testing efficiency of early psychotherapeutic interventions are needed, which the authors rightly state.
