Objective: To estimate quality of life (QoL) during the natural course of patients with untreated cerebral cavernous malformations (CCM) using a one-year longitudinal follow up.
Methods: 246 consecutive cases of CCM were included in a prospective longitudinal study assessing QoL and neurological/psychiatric constitution over the past two years in our institution. QoL was assessed by SF 36 survey (2 sum scores (physical sum score PCS/mental sum score MCS) and 8 subdomains (physical function PF, role bodily BR, bodily pain BP, general health GH, vitality VIT, social functioning SF, role emotional ER, mental health MH)), psychiatric constitution by HADS-A/D and functional condition by modified Rankin score. Longitudinal follow-up was achieved within 12 months ± 2 months. Pairwise comparison of data was performed by Wilcoxon test.
Results: So far, 73 patients of the whole cohort were re-assessed at the one year follow up, 4 were excluded as they underwent surgical treatment of the CCM in between the surveys. Therefore, n= 69 cases were included in a preliminary analysis. In these, CCM were located supratentorial (71%), in the brainstem (26%) and cerebellar (3%). Five patients showed multiple CCM, 10 suffered from cavernoma related epilepsy (CRE) and 33 were asymptomatic. Twenty-eight patients (40%) had an initial symptomatic hemorrhage. Two patients suffered from a bleeding event in between the 2 surveys. Comparing longitudinal QoL values, no significant improvement or deterioration was found. Longitudinal HADS-A scores improved significantly (p= 0.047). Subgroup analysis revealed that patients with CRE showed deterioration in most QOL subdomains and component scores.
Conclusion: It is known that diagnosis of CCM effects QoL and mental state (anxiety and depression). Our data reveals that at untreated one-year follow up, QOL does not significantly change, but anxiety levels improve (HADS-A). The latter may reflect an improvement in coping with the diagnosis. Suffering from CRE leads to decrease of QOL reflecting the specific burden of epilepsy.
