Challenges and Opportunities in Machine Learning for Light‐Emitting Polymers

open access: yesMacromolecular Rapid Communications, EarlyView.
The performance of light‐emitting polymers emerges from coupled effects of chemical diversity, morphology, and exciton dynamics across multiple length scales. This Perspective reviews recent design strategies and experimental challenges, and discusses how machine learning can unify descriptors, data, and modeling approaches to efficiently navigate ...

Patient‐Reported Communication Decline Following Deep Brain Stimulation in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Objective decline in communication abilities following Deep Brain Stimulation (DBS) in People with Parkinson's disease (PwP) is common; however, patient perspectives remain under‐investigated. Objectives This study examined subjective change in communicative efficacy using the Communicative Participation Item Bank (CPIB) in PwP ...

Alzheimer's Biomarkers and Visuospatial Cognition in Parkinson's Disease: Modification by α‐Synuclein and Mediation of Age Effects

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Visuospatial deficits in Parkinson's disease (PD) often precede dementia and complicate daily functioning. Alzheimer's disease (AD) pathology and α‐synuclein aggregation frequently co‐occur in PD, but their combined impact on cognition is unclear.

Early Autonomic Burden in Prodromal Parkinson's Disease Predicts Cognitive Impairment

open access: yesMovement Disorders, EarlyView.
Abstract Background Autonomic dysfunction is a known contributor to cognitive impairment in Parkinson's disease (PD), but its impact during prodromal stage is unknown. Objective The aim was to determine whether early autonomic burden predicts incident cognitive impairment in prodromal PD.

In Vivo Mapping of Catecholaminergic Loss and Iron Deposition in Huntington's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background The pathophysiology of Huntington's disease (HD) remains obscure. Magnetic resonance imaging (MRI) can reveal in vivo molecular changes related to disease pathology. Objectives To investigate catecholaminergic neuronal integrity and subcortical brain iron accumulation in HD employing neuromelanin‐sensitive MRI, and quantitative ...

Semantic memory

Current Neurology and Neuroscience Reports, 2002
Our concepts about objects, states, and events are stored in a cognitive structure termed semantic memory. There are several types of neurologic disorders that may cause impairments of semantic memory. Clinical evaluations of these impairments are complex, because semantic memory is linked to other cognitive systems that, when damaged, may produce ...
