Abstract
Introduction
Previous studies demonstrated an unfavorable psychological outcome after treatment of unruptured intracranial aneurysms despite an objectively favorable clinical and radiological outcome. The current study was therefore designed to analyze the psychiatric vulnerability of this specific patient collective.
Materials and methods
Patients treated for a WHO grade I meningioma and incidental intracranial aneurysms in two German neurosurgical centers between 2007 and 2013 were screened for exclusion criteria including malignant/chronic diseases, recurrence of the tumor/aneurysm after more than 12 months and focal neurological deficits, among others. Seventy-five meningioma patients (M) and 56 incidental aneurysm patients (iA) met the inclusion criteria. The past medical psychiatric history, post-morbid personality characters and coping strategies were determined by questionnaires mailed to the patients in a printed version (Brief COPE, Big Five Personality Test).
Results
Fifty-eight M and 45 iA patients returned the questionnaires. Patients with iA demonstrated significantly higher pre-interventional rates of depressive episodes (p = 0.002) and psychological supervision (p = 0.038). These findings were especially aggravated in iA patients who received their cranial imaging for unspecific symptoms such as dizziness, headaches or tinnitus (n = 33, history of depressions: 39.4 %; previous psychological supervision: 33.3 %). Furthermore, the analysis of the Big Five personality traits revealed remarkably elevated neuroticism scores in the iA collective.
Conclusion
The current study demonstrates an increased rate of positive pre-interventional psychiatric histories in the iA collective. Although those patients represent only a small subgroup, they still may play an important role concerning the overall outcome after iA treatment. Early detection and psychological support in this subgroup might help to improve the overall outcome. Further studies are needed to evaluate the influence of this new aspect on the multifactorial etiology of unfavorable psychiatric outcome after treatment of iA.

Comment
Although this relatively small follow-up study carried out in highly selected patients with subgroup analyses and multiple significance testing is vulnerable to bias, it nevertheless adds to the growing but still weak knowledge concerning the possible psychiatric comorbidity in patients with intracranial aneurysms. Neuroticism is probably a risk factor for most incidental intracranial findings. Without concern about and attention to often unspecific symptoms, patients do not seek medical attention and are not diagnosed. Furthermore, aneurysms may be incidentally discovered, but they do not develop randomly. Lifestyle-related factors such as smoking and hypertension are strong risk factors and are probably associated with psychological vulnerability on a group level. Also, when considering prophylactic treatment surgeons may at times perhaps favor active interventions in overly anxious or vulnerable patients to offer relief or help them move on. In summary, our aneurysm patients are not the average Joe or Jane, and this may affect treatment results for soft outcomes.
