Burden of incidental cerebral aneurysms on lifestyle and quality of life: a survey of patients in expectant management (the SPICE Study).

Background: The increasing availability of neuroimaging tests has led to a rise in the identification of incidental unruptured intracranial aneurysms (UIAs). Their management is under debate, with no consensus on their follow-up strategy, which can cause anxiety in patients. Our aim is to evaluate the impact of diagnosis and imaging follow-up on daily activities and quality of life.

Methods: A multicenter cross-sectional study was carried out in patients with UIAs undergoing watchful waiting. Exclusion criteria were history of stroke, renal polycystic disease, symptomatic aneurysms, intervention or scheduled for intervention. The patients completed an anonymous 36-question survey about their habits and perceived quality of life after diagnosis through a validated questionnaire (PROMIS).

Results: We obtained 73 responses from 183 patients identified in eight hospitals (40%), 68 of which were included in the study (50 women (74%), median (IQR) age 62 (55-70) years). Forty-nine patients (72%) underwent at least one imaging follow-up per year. Forty-two patients (63%) found follow-up tests reassuring and 12 (18%) experienced concern about the results. Nineteen patients (28%) reported adopting a healthier lifestyle since diagnosis, while 13 (19%) acknowledged a negative impact on their daily activities. Forty-six (68%) admitted avoiding or conditioning at least one activity or situation from a list. PROMIS scores were similar to those of the general reference population. Overall, 77% rated their quality of life as 'good' or better.

Conclusions: The diagnosis of UIAs seems to influence the activities of the majority of patients. However, follow-up yielded more benefit in the form of healthier lifestyles than harm to daily activities, without detriment to their perceived quality of life.
