Uric acid has been supposed to have a protective role in Parkinson's disease with controversial findings. This relationship has not been validated with pathology-confirmed diagnoses. This study aims to compare uric acid levels between pathology-confirmed and clinically-misdiagnosed Parkinson’s disease patients over time. 65 patients with an in-vivo...

Background Alzheimer's disease (AD) is a leading cause of dementia. Arterial spin labeling (ASL) MRI, particularly at 3 Tesla (3T), offers a noninvasive method to assess cerebral blood flow alterations, which are believed to be early indicators of AD. Purpose The purpose of this study is to evaluate the utility of 3T ASL MRI in identifying cerebra...

Background The effectiveness of deep brain stimulation (DBS) for Parkinson’s disease (PD) depends on implantation accuracy. DBS initially employed a stereotactic frame (frame-based, FB), but technological advancements led to the development of less invasive methods based on fiducial markers (F + F) or intraoperative imaging (F-F). This study compar...

Objective Quantitative electroencephalography (qEEG) metrics are demonstrated to correlate with and predict clinical response in individuals with epilepsy. Cenobamate is an effective anti-seizure medication recently approved as an add-on therapy for individuals with epilepsy, but its effects on qEEG are unknown. We aimed to evaluate the modulation...

Objective Despite diagnostic criteria refinements, Parkinson's disease (PD) clinical diagnosis still suffers from a not satisfying accuracy, with the post-mortem examination as the gold standard for diagnosis. Seminal clinicopathological series highlighted that a relevant number of patients alive-diagnosed with idiopathic PD have an alternative pos...

Fear of Falling (FOF) significantly affects Parkinson's Disease (PD) patients by limiting daily activities and reducing quality of life (QoL). Though common in PD, the relation between FOF, mobility, and QoL remains unclear. This study examines the connections between FOF, gait, daily motor activity, and QoL in PD patients. Fifty PD patients on sta...

High-frequency oscillations produced by external stimuli are useful for...

Importance Although up to 20% of patients with multiple sclerosis (MS) experience onset before 18 years of age, it has been suggested that people with pediatric-onset MS (POMS) are protected against disability because of greater capacity for repair. Objective To assess the incidence of and factors associated with progression independent of relapse...

Introduction: In past years, a possible bidirectional link between epilepsy and Alzheimer's disease (AD) has been proposed: if AD patients are more likely to develop epilepsy, people with late-onset epilepsy evidence an increased risk of dementia. Furthermore, current research suggested that subclinical epileptiform discharges may be more frequent...

The semantic variant of primary progressive aphasia (svPPA), known also as “semantic dementia (SD),” is a neurodegenerative disorder that pertains to the frontotemporal lobar degeneration clinical syndromes. There is currently no approved pharmacological therapy for all frontotemporal dementia variants. Transcranial direct current stimulation (tDCS...
