Association Between Gas‐Free Cerebrovascular Reactivity (CVR) and Cognitive Function in Older Adults With a High Risk for Vascular Dementia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. Cerebrovascular reactivity (CVR) is a promising biomarker for VCID. However, CVR is not commonly measured in clinical practice due to logistical difficulties in applying a hypercapnia challenge during MR imaging. Purpose To investigate whether

Spatiotemporal dynamics of brain function network during proprioception rehabilitation after anterior cruciate ligament reconstruction: A randomized trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
The improvement of proprioceptive function after ACLR is related to the optimization of spatiotemporal dynamics of SM, CC, DM, CB and VI functional networks. Rehabilitation optimization can incorporate visual–cognitive dual‐task exercises. Abstract Purpose In this study, we aimed to examine the dynamic functional network connectivity (dFNC) patterns ...

Discrepant Views of Apathy in Patients and Caregivers: the Role of Cognitive Deficits in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Apathy is a common early symptom of Parkinson's disease (PD), often co‐occurring with cognitive decline and associated with fronto‐striatal and mesocortico‐limbic dysfunctions. Discrepancies between self‐ and caregiver‐reported apathy have been preliminarily associated with cognitive impairments affecting patients’ awareness and ...

Sex Classification Based on the Functional Connectivity Patterns of the Language Network: A Resting State fMRI Study. [PDF]

Hum Brain Mapp
We classified the resting‐state functional connectivity patterns anchored to core regions of the language network in a large sample of healthy young adults. The results showed that these patterns contain information capable of predicting sex with an accuracy of 91.3% on the test set and 78.1% on the holdout set.

Brain Imaging Changes Following Deep Brain Stimulation Patients with Parkinson's Disease: A Literature Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's Disease (PD) is a progressive neurodegenerative disorder primarily characterized by motor symptoms such as tremors, rigidity, and bradykinesia. Structural brain changes, including atrophy in the midbrain, basal ganglia, and cortical regions such as the frontal and temporal lobes, are observed in advanced stages.

Preoperative Functional Connectivity Predicts Antiparkinson Drug Change after Deep Brain Stimulation

Movement Disorders, EarlyView.
Abstract Background Deep brain stimulation (DBS) can effectively ameliorate motor symptoms in Parkinson's disease (PD), but patient outcomes remain variable. Clinical predictors lack reliability and only explain a small proportion of outcome variance, outlining a need for biomarkers that can enhance prediction accuracy.

Constipation Is Linked to Neuroinflammation in Early Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Constipation is a risk factor for the onset and accelerated progression of Parkinson's disease (PD), but the mechanisms underlying this association are unknown. Neuroinflammation in PD has been demonstrated in postmortem and neuroimaging studies; however, its relationship with constipation has not been investigated.

Functional Connectivity to the Cerebellum and Resting‐State Networks Predict Earlier Improvement of Dystonia Following Globus Pallidus Internus‐Deep Brain Stimulation (GPi‐DBS)

Movement Disorders, EarlyView.
Early improvement of dystonia after globus pallidus internus‐deep brain stimulation (GPi‐DBS) is associated with stimulation of the globus pallidus externus‐subthalamic nucleus (GPe‐STN) fibers and the lenticular fasciculus. Functional connectivity to the cerebellar cortex and the limbic and default mode networks predict early improvement of symptoms ...

Longitudinal Awake Mouse fMRI During Voluntary Locomotion Using Zero TE Imaging and a Novel Treadmill Training Protocol

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Functional MRI (fMRI) in awake rodents presents countless valuable opportunities for researchers to probe questions that may not be accessible through anesthetized models, such as voluntary locomotion. The commonly used echo planar imaging (EPI) sequence is highly sensitive to motion that occurs even outside of the imaging plane ...
