Functional and structural connectivity measures, as assessed by means of functional and
diffusion MRI, are emerging as potential intermediate biomarkers for Alzheimer disease (AD) …

Mild cognitive impairment (PD-MCI) and dementia (PDD) are among the most frequent non-
motor symptoms in Parkinson's disease (PD). PD-MCI is six times more likely than age …

Brain changes have been reported in the first weeks after SARS-CoV-2 infection. However,
limited literature exists about brain alterations in post-COVID syndrome, a condition …

Background Dementia is common in Parkinson's disease (PD) but measures that track
cognitive change in PD are lacking. Brain tissue iron accumulates with age and co-localises …

Cognitive decline is one of the most frequent and disabling nonmotor features of Parkinson's
disease. Around 30% of patients with Parkinson's disease experience mild cognitive …

Objective To use a multimodal approach to assess brain structural pathways and resting
state (RS) functional connectivity abnormalities in patients with Parkinson's disease and …

Background The aim of this work was to investigate the cortical and white matter changes
that underlie cognitive impairment in patients with incident Parkinson's disease (PD) disease …

L-DOPA is still the most effective pharmacological therapy for the treatment of motor
symptoms in Parkinson's disease (PD) almost four decades after it was first used. Deep …

Parkinson disease (PD) is associated with cognitive impairment. We aimed to determine the
effects of intranasal insulin (INI) on cognition and motor performance in PD. This was a proof …

Cognitive impairment in patients with Parkinson's disease (PD) is one of the commonest and
most disabling non-motor manifestations during the course of the disease. The clinical …
