ObjectiveAlthough shunting has been shown to ameliorate symptoms in idiopathic normal pressure hydrocephalus (iNPH), its impact on health-related quality of life (HRQoL) has yet to be fully elucidated. Patient and caregiver subjective life satisfaction and HRQoL represent crucial indicators for assessing the well-being of individuals facing chronic illnesses, including iNPH. This study aimed to systematically analyze the existing data about HRQoL in iNPH-treated patients to evaluate the role of surgical treatment in such a scenario.MethodsUsing Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the literature in the PubMed/Medline, Web of Science, and Scopus databases was searched. Fourteen studies met our inclusion criteria. The Joanna Briggs Institute critical appraisal tool was used to assess the risk of bias.ResultsOverall, HRQoL improved significantly within 1 year after shunt placement although patients with iNPH reported worse HRQoL values compared with healthy-matched individuals. Up to 5 years after shunting, a sustained heterogeneity exists on published data showing improved scores across all domains for at least 21 months after shunting. Further, although surgical treatment can improve HRQoL, long-term follow-up showed that it remained lower than that of healthy controls. These data suggest a significant decrease of HRQoL in patients with iNPH over time after shunting, probably due to aging, comorbidities, and disease progression.ConclusionsDespite that iNPH has been recognized as a potentially reversible neurological disorder, the available data about the impact of shunting on the HRQoL are unsatisfactory. To improve the well-informed clinical decision-making, it is essential to reach additional high-quality evidence regarding the effect of shunting on HRQoL. New prospective studies, using validated instruments specifically tailored for assessing HRQoL in patients with iNPH, and improved reporting standards are needed. Current evidence suggests that although shunting can provide initial benefits, affected patients may experience long-term impairment in HRQoL.Copyright © 2023 Elsevier Inc. All rights reserved.
