Brain age and Alzheimer's-like atrophy are domain-specific predictors of cognitive impairment in Parkinson's disease.

TLDR
In this article, an MRI index capturing Alzheimer's disease-like atrophy, and atrophy-based estimates of brain age were computed from longitudinal structural imaging data of 178 PD patients and 84 healthy subjects from the LANDSCAPE cohort.

Morphological basis of Parkinson disease-associated cognitive impairment: an update

TL;DR: Large-scale clinicopathological correlative studies are warranted to further elucidate the exact neuropathological correlates of cognitive impairment in PD and related synucleinopathies as a basis for early diagnosis and future disease-modifying therapies.
Journal ArticleDOI

Cognitive heterogeneity in Parkinson’s disease: A mechanistic view

TL;DR: A review of the current clinical landscape surrounding cognition in Parkinson's disease can be found in this paper , where the authors discuss how cognitive impairment and dementia may develop in PD based on the spread of the pathological protein alpha-synuclein (aSyn) from neurons in brainstem regions to those in the cortical regions of the brain responsible for higher cognitive functions.

Neuroimaging-Based Brain Age Estimation: A Promising Personalized Biomarker in Neuropsychiatry

TL;DR: A review of the clinical applications of brain age estimation in neuropsychiatry and general populations can be found in this article , where the authors provide an introduction to typical neuroimaging modalities, feature extraction methods, and machine-learning models that have been used to develop a brain-age estimation framework.

Analysis of longitudinal data

TL;DR: In this paper, a generalized linear model for longitudinal data and transition models for categorical data are presented. But the model is not suitable for categric data and time dependent covariates are not considered.

Mild cognitive impairment as a diagnostic entity

TL;DR: It is suggested that the diagnosis of mild cognitive impairment can be made in a fashion similar to the clinical diagnoses of dementia and AD, and an algorithm is presented to assist the clinician in identifying subjects and subclassifying them into the various types of MCI.

N4ITK: Improved N3 Bias Correction

TL;DR: A variant of the popular nonparametric nonuniform intensity normalization (N3) algorithm is proposed for bias field correction with the substitution of a recently developed fast and robust B-spline approximation routine and a modified hierarchical optimization scheme for improved bias field Correction over the original N3 algorithm.

MR signal abnormalities at 1.5 T in Alzheimer's dementia and normal aging

TL;DR: The frequently observed "halo" of periventricular hyperintensity in Alzheimer's disease may be of diagnostic importance and high-signal abnormalities in specific cortical regions are likely to reflect disease processes localized to those structures.
