Brief Summary
We hypothesise that a real-time quaking induced conversion assay for the detection of pathological alpha-synuclein (α -syn RTQuIC) can be used to differentiate between cases of idiopathic REM-sleep behaviour disorder (RBD) and RBD that is symptomatic of prodromal α-synucleinopathies.

Outcome Measures
Primary Outcomes (1)
Presence of pathological α-synuclein within the cerebrospinal fluid (CSF)
The primary outcome measure will be either a positive/negative (binary) result from the α-syn RT-QuIC assay. A positive output confirms presence of pathological α-synuclein within the CSF.
0-24 months after sample taken
