OBJECTIVE To determine the predictive value of clinical assessment and dopamine transporter (DAT) uptake for the early development of neurodegenerative synucleinopathy diseases from idiopathic REM sleep behavior disorder (iRBD) over 5 years in a Chinese population. METHODS Forty-three patients with iRBD were administered clinical assessment tests, and 35(More)
Catechol-O-methyltransferase (COMT) is one of the cardinal enzymes that metabolize dopamine and other catecholamine neurotransmitters in the central and peripheral nervous system. Recent studies have shown that the impact of COMT haplotypes on the development of wearing-off phenomenon is in dispute, while the relationship between COMT haplotypes and(More)
Dopamine transporter based imaging has high diagnostic performance in distinguishing patients with Parkinson’s disease (PD) from patients with non-Parkinsonian syndromes. Our previous study indicated that the “Sniffin’ Sticks” odor identification test (SS-16) acts as a valid instrument for olfactory assessment in Chinese PD patients. The aim of the study(More)
The present study was to evaluate the diagnostic value of salivary total and oligomeric α-synuclein levels in PD. Furthermore, we sought to explore the relationship between salivary total α-synuclein and α-synuclein SNP variants levels. 201 PD patients and 67 controls were recruited, of which there also had the genetic information of two positive(More)
