Substantia nigra hyperechogenicity in male methamphetamine users
Objective: To investigate the effect of sex on substantia nigra (SN) echogenicity in young-to-middle aged adults with a history of methamphetamine use. Background: The sonographic…Evaluation of serum sestrin protein in Parkinson’s disease: a plausible diagnostic marker
Objective: In this study, we evaluated the concentrations of sesn1 and sesn2 in the serum of 50 PD patients and 60 elderly controls. Aging is…Cardiac 123I-MIBG Scintigraphy, olfactory testing and transcranial sonography for differentiating between Parkinson’s disease and atypical parkinsonian syndromes during the early stage
Objective: To evaluate the utility of the combined use of cardiac metaiodobenzylguanidine (MIBG) scintigraphy, olfactory testing, and substantia nigra (SN) hyperechogenicity on transcranial sonography (TCS)…A follow-up study of hyperechogenicity of the substantia nigra in Parkinson’s disease and atypical parkinsonian syndrome
Objective: To evaluate whether the hyperechogenic size of the substantia nigra changes with time in Parkinson's disease (PD) and atypical parkinsonian syndromes (APSs), such as…Substantia nigra area evaluated by neuromelanin-sensitive MRI as an imaging biomarker of disease progression in Parkinson’s disease
Objective: to investigate the pattern of substantia nigra - neuromelanin (SN-NM) area loss and contrast ratio (CR) intensity changes in late-stage Parkinson’s disease (LSPD) patients,…Frequency of echogenic abnormality of the substantia nigra is increased in methamphetamine users
Objective: To investigate structural abnormality of the substantia nigra (SN) in methamphetamine users using transcranial sonography (TCS). Background: Epidemiologic studies suggest that chronic use of…Substantia nigra hyperechogenicity in Parkinson´s disease motor phenotypes
Objective: To evaluate substantia nigra hyperechogenicity (SN+) with transcranial sonography (TCS) in different PD motor subtypes. Background: Parkinson´s disease (PD) patients display a range of…Evolution of mild Parkinsonian signs in a longitudinal population-based cohort
Objective: To investigate evolution of mild Parkinsonian signs (MPS) in an ongoing longitudinal study on Parkinson's disease (PD). Background: Mild motor impairmant may progress to…MRI signatures of the brain of Parkinson’s disease and idiopathic REM sleep behavioral disorder subjects
Objective: To characterize brain microstructural integrity, iron loads, and functional connectivity in 10 idiopathic rapid eye movement sleep behavior disorder (RBD), 10 Parkinson's disease (PD)…Application of the MDS research criteria for prodromal Parkinson’s disease to the longitudinal population-based Bruneck study cohort
Objective: To quantify the prevalence of prodromal phase of Parkinson's disease (PD) defined per 2015 MDS research criteria and their potential to predict incident clinically…
