BASELINE OLFACTION TESTING IN PARKINSON’S DISEASE PATIENTS IS CORRELATED WITH LONG-TERM DOPAMINERGIC DENERVATION IN STRIATAL SUB-REGIONS: LONGITUDINAL DATA FROM THE PPMI STUDY.
Objective: The aim of the current study was to determine whether there are longitudinal differences in dopaminergic denervation of striatal sub-regions [signal reduction in 123I-FP-CIT…Relationship Between Hyposmia and Olfactory Network Connectivity in Patients With Parkinson’s Disease
Objective: To examine resting-state functional Magnetic Resonance Imaging in a group of Parkinson’s Disease patients, used to characterize changes in functional connectivity of the olfactory…Predictive value of UPSIT subsets in prodromal Parkinson disease
Objective: To assess the predictive value of previously published subsets of the University of Pennsylvania Smell Identification Test (UPSIT) odors for conversion to Parkinson disease…Serial olfactory testing for the diagnosis of prodromal Parkinson disease in the Parkinson Associated Risk Syndrome (PARS) study
Objective: To assess whether repeat olfactory testing in initially hyposmic subjects improves prediction of conversion to Parkinson disease (PD). Background: Hyposmia is a common prodromal…Smell dysfunction correlates with severity of motor deficits in H&Y stage-I early onset Parkinson’s disease
Objective: The objective of this study is to test the hypotheses that: 1) olfactory dysfunction in early stage Parkinson’s disease (PD) is correlated with severity…Olfactory dysfunction and its relationship with clinical features of Parkinson’s disease
Objective: To investigate the reliability of assessing olfactory function of patients with PD by HRS in China and compare other non-motor features between patients with PD…Parkinson Progression Marker Initiative 2.0 – New Science/New Cohorts
Objective: The Parkinson Progression Marker Initiative 2.0 (PPMI 2.0) is a longitudinal, observational, multi-center natural history study to assess progression of clinical features, digital outcomes,…Olfactory impairment in Wilson’s disease
Objective: Olfactory dysfunction is a very common and early sign of many neurodegenerative disorders, but little is known about olfactory dysfunction in Wilson’s disease (WD).…Assessing the screening performance of three abbreviated smell tests in Parkinson’s disease
Objective: We aimed to: a) determine the effectiveness of two shortened six-item ‘scratch-and-sniff’ smell tests and an alternative novel alginate capsule scent delivery system in…Improving estimation of Parkinson’s disease risk – enhancing the PREDICT-PD algorithm
Objective: To develop and test an enhanced algorithm for the prediction of Parkinson’s disease (PD) risk. Background: The PREDICT-PD algorithm estimates risk of PD using…
