Description
Isolated REM Sleep Behavior Disorder (iRBD) is the strongest prodromal marker for conversion to α-synucleinopathies. A continuum between aging and neurodegeneration has been proposed, but this hypothesis has not been tested in iRBD so far. Here we used epigenetic clocks, estimated from DNA methylation arrays using the DNA Methylation Age Calculator available at https://dnamage.genetics.ucla.edu/home, to measure biological aging in videopolysomnography-confirmed iRBD patients (iRBDs, n=28), videopolysomnography-negative controls (CTR_neg; n=57), and controls from the general population (CTR_pop; n=31).
