Quality of life (QoL) disturbances are common after aneurysmal subarachnoid hemorrhage (aSAH) both in physical and mental health domains and their causes are not clearly understood. Corticotropin-releasing hormone receptor 1 (CRHR1) is involved in stress reactivity and development of mental health disturbances after negative life-events. We performed a retrospective cohort study of long-term QoL outcomes among 125 surgically treated aSAH patients (2001–2013). QoL was assessed with Short Form Health Survey (SF-36) and compared to an age and gender matched general population. Genotyping of CRHR1 single nucleotide polymorphisms was performed (Rs7209436, Rs110402, Rs242924) and their effect on QoL scores was explored. aSAH patients experienced a reduced quality of life in all domains. CRHR1 minor genotype was associated with higher SF-36 mental health (OR = 1.31–1.6, p < 0.05), role-emotional (OR = 1.57, p = 0.04) and vitality scores (OR = 1.31–1.38, p < 0.05). Association of all studied SNP’s with vitality and Rs242924 with mental health scores remained statistically significant after Bonferroni correction. Mental quality of life scores were associated with physical state of patients, antidepressant history and CRHR1 genotype. Predisposition to mental health disturbances after stressful life-events might be associated with reduced mental QoL after aSAH and selected patients could be provided advanced counselling in the recovery phase.
