Purpose To investigate the structural brain connectome in patients with Parkinson disease
(PD) and mild cognitive impairment (MCI) and in patients with PD without MCI. Materials and …

In Parkinson's disease (PD), cortical–subcortical interplay plays a relevant role in affecting
clinical performance. Functional MRI sequences described changes in functional …

Parkinson's disease (PD) is characterized by overlapping motor, neuropsychiatric, and
cognitive symptoms. Worse performance in one domain is associated with worse …

Parkinson's disease (PD) can be classified into tremor-dominant and akinetic-rigid subtypes,
each of which exhibits a unique clinical course and prognosis. The neural basis for these …

Parkinson's disease (PD) is characterized by complex clinical symptoms, including classic
motor and nonmotor disturbances. Patients with PD vary in clinical manifestations and …

Parkinson's disease (PD) is a neurodegenerative disease with cognitive as well as motor
impairments. While much is known about the brain networks leading to motor impairments in …

To date, regional brain atrophy unfolded using neuroimaging methods is observed to be the
signature of Parkinson's disease (PD). In addition, graph theory-based studies are proving …

Cognitive impairment in Parkinson's disease (PD) is related to the reorganization of brain
topology. Although drug challenge studies have proven how levodopa treatment can …

Aim: The aim of the present study is to investigate the relationship between both functional
connectivity and brain networks with cognitive decline, in patients with Parkinson's disease …

Background Tracking longitudinal functional brain dysconnectivity in Parkinson's disease
(PD) is a key element to decoding the underlying physiopathology and understanding PD …
