Phenoconversion in Pure Autonomic Failure
JAMA Neurology 10.1001/jamaneurol.2026.0989May 04, 2026 at 11:00 AM EDT
What are the incidence rate and predictors of phenoconversion to central α-synucleinopathies in pure autonomic failure (PAF)?In this systematic review and meta-analysis of 9 longitudinal cohort studies including 900 patients with PAF during 6.4 years of follow-up, phenoconversion incidence rate to any central α-synucleinopathy was markedly higher than that of the general population, approximately 5% per year.Findings suggest that PAF may be a prodromal presentation of central α-synucleinopathies, and future research should focus on the accurate identification of those at high risk of phenoconversion using a combination of clinical features and biomarkers to allow potential early interventions.
