REM sleep behavior disorder and REM sleep without atonia in Parkinson’s disease
RBD and REM sleep without atonia are frequent in PD as shown by PSG recordings, and their cases may represent preclinical forms of RBD associated with PD.

The risk of developing neurodegenerative disease in idiopathic REM sleep behavior disorder is substantial, with the majority of patients developing Parkinson disease and Lewy body dementia.
Mild cognitive impairment in rapid eye movement sleep behavior disorder and Parkinson's disease
To investigate the frequency and subtypes of mild cognitive impairment (MCI) in idiopathic rapid eye movement sleep behavior disorder (RBD) and Parkinson's disease (PD) in association with RBD.
Severity of REM atonia loss in idiopathic REM sleep behavior disorder predicts Parkinson disease
In patients with REM sleep behavior disorder initially free of neurodegenerative disease, the severity of REM atonia loss on baseline polysomnogram predicts the development of Parkinson disease.

It is recommended to screen patients with Parkinson disease for mild cognitive impairment, orthostatic hypotension, and RBD even at baseline visits to identify a diffuse/malignant subgroup of patients with PD for whom the most rapid progression rate could be expected.

The presence of altered motor subtypes in PD with RBD suggests that patients with PD and RBD may have a different underlying pattern of neurodegeneration than PD patients without RBD.

Using direct assessment of motor examination before parkinsonism in a REM sleep behaviour disorder, a prodromal interval of ∼4.5 years is estimated on the Unified Parkinson's Disease Rating Scale; other quantitative markers may detect parkinsonistan earlier.
