Early BMI Change, Cognitive Decline, and CSF AD Biomarkers Alterations in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the relationship of early BMI change with subsequent cognitive decline, CSF AD biomarkers alterations, and progression to dementia in patients with PD. Methods Study data were prospectively collected from the PPMI cohort. Weight/height data at enrollment and second‐year clinical visit were utilized to calculate BMI change.

Detecting neural activity and connectivity by perfusion-based fMRI [PDF]

arXiv, 2017
This study proposes an approach to estimate the functional localization and connectivity from CBF and BOLD signals simultaneously measured by ASL (arterial spin labeling) MRI, especially using exploratory Structural Equation Modeling analysis. In a visual task experiment, the primary visual cortices were located by analyzing the perfusion data.

Claustrum Volume Is Reduced in Multiple Sclerosis and Predicts Disability

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The claustrum is a small, thin structure of predominantly gray matter with broad connectivity and enigmatic function. Little is known regarding the impact of claustrum pathology in multiple sclerosis (MS). Methods This study assessed whether claustrum volume was reduced in MS and whether reductions were associated with specific ...

Early Language Impairment as an Integral Part of the Cognitive Phenotype in Huntington's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Huntington's disease (HD) speech/language disorders have typically been attributed to motor and executive impairment due to striatal dysfunction. In‐depth study of linguistic skills and the role of extrastriatal structures in HD is scarce.

A Novel CHMP2B Splicing Variant in Atypical Presentation of Familial Frontotemporal Lobar Degeneration

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT C‐truncating variants in the charged multivesicular body protein 2B (CHMP2B) gene are a rare cause of frontotemporal lobar degeneration (FTLD), previously identified only in Denmark, Belgium, and China. We report a novel CHMP2B splice‐site variant (c.35‐1G>A) associated with familial FTLD in Spain. The cases were two monozygotic male twins who

How transcranial direct current stimulation facilitates post-stroke rehabilitation [PDF]

arXiv, 2019
Whether transcranial direct current stimulation (tDCS) benefits stroke rehabilitation remains unclear. To investigate how tDCS reorganizes brain circuitry, nineteen post-stroke patients underwent rehabilitation sessions with bi-hemispheric real vs sham tDCS intervention. Resting motor threshold measurements showed tDCS evoked higher excitability in the

The Hyper-Cortex of Human Collective-Intelligence Systems [PDF]

arXiv, 2005
Individual-intelligence research, from a neurological perspective, discusses the hierarchical layers of the cortex as a structure that performs conceptual abstraction and specification. This theory has been used to explain how motor-cortex regions responsible for different behavioral modalities such as writing and speaking can be utilized to express ...

Cerebello‐Prefrontal Connectivity Underlying Cognitive Dysfunction in Spinocerebellar Ataxia Type 2

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 2 (SCA2) is a hereditary cerebellar degenerative disorder, with motor and cognitive symptoms. The constellation of cognitive symptoms due to cerebellar degeneration is named cerebellar cognitive affective syndrome (CCAS), which has increasingly been recognized to profoundly impact patients' quality of life;

Dynamic alterations in cortical activation during motor adaptation in table tennis using whole‑brain fNIRS

Scientific Reports
Human movements must constantly be adapted due to changing internal and external conditions in our environment. The underlying neuronal mechanisms that are responsible for motor adaptations have so far mainly been investigated in highly controlled ...
