Objective: To determine serum 25-hydroxy vitamin D (25OHD) concentration at diagnosis and 18 months in incident Parkinson's disease (PD) compared to controls and to investigate…Verb naming in hypokinetic and hyperkinetic movement disorders: Preliminary results
Objective: To investigate verb naming differences in hypokinetic (Parkinson's disease, PD) and hyperkinetic (primary cervical dystonia, PCD) movement disorders; and to determine whether different effects…Urate and homocysteine: Changes in motor and cognitive symptoms in newly diagnosed Parkinson’s disease
Objective: 1) To determine serum urate and homocysteine concentration at baseline, 18 and 36 months in control and PD participants. 2) To determine if urate…Emotional modulation of the startle reflex in essential tremor: Evidence of altered cerebellar input into limbic circuitry?
Objective: To examine whether Essential Tremor (ET) is associated with subtle changes in emotion processing, in parallel with those observed in the cognitive domain, using…Effects of zonisamide on dementia with Lewy bodies (DLB): A post-hoc analysis of phase 2 study for parkinsonism in DLB patients
Objective: To clarify the effects of zonisamide (ZNS) on the core symptoms of dementia with Lewy bodies (DLB), we performed a post-hoc analysis using data…Relationship of MDS-UPDRS non-motor symptoms to cognitive functioning in patients with Parkinson’s disease
Objective: To evaluate the relationship among individual items from the MDS-UPDRS Part I and measures of cognitive functioning in patients with PD. Background: Non-motor symptoms…Speech prosody impairment predicts cognitive decline in Parkinson’s disease
Objective: We assessed whether baseline speech prosodic parameters, alone or in combination with other predominantly non-dopaminergic symptoms may predict global cognitive decline as measured by…Analysis of factors associated with cognitive and functional performance in Parkinsonian with normal mini-mental state examination
Objective: To evaluate the correlation between cognitive and functional performance of Parkinsonian with normal Mini-Mental State Examination (MMSE), and demographic variables, motor impairment, neuropsychiatric disorders…
