DOI: 10.1016/j.sleep.2020.02.012

Abstract: OBJECTIVES Hyperechogenicity of the substantia nigra (SN) and abnormal dopamine transporter-single-photon emission computed tomography (DAT-SPECT) are biomarkers commonly used in the assessment of prodromal synucleinopathy. Our goals were as follows: (1) to compare echogenicity of… read more here.

DOI: 10.1016/j.sleep.2021.04.033

Abstract: Abnormal motor manifestations in REM sleep are the most visible feature of idiopathic REM sleep behavior disorder (iRBD), which precedes the overt alpha-synucleinopathy. The aim of this study was to perform a systematic visual analysis… read more here.

DOI: 10.1212/wnl.0000000000213463

Abstract: Background and Objectives Diagnosing dementia with Lewy bodies (DLBs) is challenging because of symptom overlap with other neurodegenerative diseases. Although dysautonomia is a recognized supportive diagnostic criterion, its prevalence and extent remain underexplored. We aimed… read more here.

DOI: 10.3390/biomedicines11020296

Abstract: Background: Parkinson’s disease (PD) is characterized by a progressive loss of nigrostriatal dopaminergic neurons with impaired motor and non-motor symptoms. It has been suggested that motor asymmetry could be caused due to an imbalance in… read more here.
