Association of Parkinson’s disease severity and cortical and subcortical cognitive markers
Objective: To assess cortical and subcortical dysfunction in several stages of Parkinson's disease (PD) using the Parkinson's disease-cognitive rating scale (PD-CRS). Background: Cognitive impairment in…Neuropsychological subgroups in non-demented Parkinson’s disease: A latent class analysis
Objective: Identify discrete cognitive phenotypes in a cohort of 199 non-demented Parkinson's disease (PD) patients. Background: Methods to detect early cognitive decline and account for…Optogenetic silencing of locus coeruleus activity in mice impairs cognitive flexibility in an attentional set-shifting task
Objective: In this study we used unilateral optogenetic silencing of the LC in an attentional set-shifting task (ASST) to evaluate the influence of the LC…Synaptic biomarkers for cognitive decline in Lewy body dementias and Alzheimer’s disease. A mass spectrometry approach
Objective: The aim of our study is to understand the role of synaptic dysfunction in cognitive decline by comparing the whole proteome of Parkinson's disease…Circulatory levels of BDNF correlate with cognitive deficits in people with Parkinson’s disease
Objective: The aim of this study was to examine the relationship of serum BDNF levels with cognitive function. Background: Brain-derived neurotrophic factor (BDNF) is essential…A technological solution for monitoring Parkinson’s disease: A patient-based perspective on necessity, usability and acceptability
Objective: The objectives of this study were twofold. First, to determine the feasibility of monitoring changes in how people with Parkinson's feel, think, and behave…Mild cognitive impairment is linked with white matter degeneration in the cortico-subcortical tracts in patients with Parkinson’s disease
Objective: Evaluate the correlation between brain tractography changes in patients with Parkinson's disease (PD) with and without mild cognitive impairment (MCI). Background: Up to 40%…Construct validity of Moca test in a sample of patients with Parkinson´s disease in Bogotá and Cali – Colombia
Objective: To evaluate of construct validity for a sample of patients with PD in Bogotá and Cali - Colombia. Background: Parkinson´s disease (PD) is a…Mental simulation of whole-body movements in patients with isolated cervical dystonia
Objective: To explore mental transformation of whole-body images in patients with isolated cervical dystonia (CD). Background: Mental transformation of bodies or of body-part images is…Brain structural abnormalities in multiple system atrophy patients with cognitive impairment
Objective: To investigate the cerebral anatomical changes associated with cognitive impairment (CI) in multiple system atrophy (MSA). Background: Mild cognitive deficits are frequently reported in…
