Clinical and brain volumetric correlates of decreased DTI-ALPS, suggestive of local glymphatic dysfunction, in iRBD

Abstract Glymphatic alterations may underlie neurodegeneration in alpha-synucleinopathies. Reduced Diffusion-Tensor Imaging ALong the Perivascular Space (DTI-ALPS), a proxy of perivascular glymphatic activity, has been scarcely studied in isolated REM sleep behaviour disorder (iRBD), a prodromal syn...
