Clinicopathologic and Neuroimaging Correlations of Nonverbal Oral Apraxia in Patients with Neurodegenerative Disease

Nonverbal Oral Apraxia in Patients with Neurodegenerative Diseases: Clinical-Pathological and Neuroimaging Correlations Research Background Nonverbal Oral Apraxia (NVOA) is a condition characterized by the inability to plan, sequence, and execute voluntary oral-facial movements without muscle weakness. NVOA was first identified in stroke patients, ...

Incidence of Primary Progressive Apraxia of Speech and Primary Progressive Aphasia in Olmsted County, MN, 2011–2022

Study on the Incidence of Primary Progressive Apraxia of Speech and Primary Progressive Aphasia in Olmsted County (2011-2022) Background and Study Objectives Primary Progressive Aphasia (PPA) and Primary Progressive Apraxia of Speech (PPAOS) are rare neurodegenerative diseases that respectively lead to the degeneration of language abilities and spe...

Graded Multidimensional Clinical and Radiologic Variation in Patients with Alzheimer Disease and Posterior Cortical Atrophy

Research Report on Progressive Multidimensional Clinical and Radiological Variations in Patients with Alzheimer’s Disease and Posterior Cortical Atrophy Background Introduction Alzheimer’s Disease (AD) has multiple phenotypes, including the typical amnestic and non-amnestic (atypical) phenotypes. Posterior Cortical Atrophy (PCA) is a prominent atyp...

Pathologic Substrates of Structural Brain Network Resilience and Topology in Parkinson Disease Decedents

Scientific Paper News Report: Pathological Basis and Topological Properties of Structural Brain Networks in Parkinson’s Disease Patients Background and Research Objectives In Parkinson’s disease (PD), α-synuclein spreads between connected brain regions, leading to neuronal loss and brain network disruption. Using diffusion-weighted imaging (DWI), t...

Diagnostic Accuracy of an Integrated AI Tool to Estimate Gestational Age from Blind Ultrasound Sweeps

Diagnostic Accuracy of AI Tools for Estimating Gestational Age Based on Blind Ultrasound Scanning Background Accurate estimation of gestational age (GA) is the foundation of good prenatal care, typically achieved through ultrasound examinations. However, many low-resource areas lack sufficient ultrasound equipment, making accurate GA estimation cha...

Blue Autofluorescence Generated by Aβ Aggregation Illuminates Senile Plaques and Complex Blood and Vascular Pathologies in Alzheimer’s Disease Research Background Alzheimer’s disease (AD) is a widespread neurodegenerative disorder globally, with senile plaques being the main pathological hallmark of AD, primarily composed of β-amyloid protein (Aβ)....

Smart (Splitting‑Merging Assisted Reliable) Independent Component Analysis for Extracting Accurate Brain Functional Networks

Smart Independent Component Analysis (SMART ICA): An Innovative Method for Extracting Accurate Brain Functional Networks Background Introduction In brain science research, Functional Networks (FNs) show great potential for understanding human brain function by exploring the integration and interaction relationships between different brain regions. ...

Compensation or Preservation? Different Roles of Functional Lateralization in Speech Perception of Older Non-Musicians and Musicians

The Impact of Music Training on Language Perception in Older Adults Under Global Aging Challenges Research Background As global population aging accelerates, the decline in language perception ability of older adults in noisy environments has become a notable issue. Older adults, even with normal hearing, often encounter the “cocktail party problem...

Sex-Dimorphic Kidney-Brain Connectivity Map of Mice

Sexual Dimorphism in the Mouse Kidney-Brain Connectome In recent years, an increasing number of studies have shown that kidney function is not only influenced by local self-regulation and hormonal systems but is also largely regulated by the nervous system. Although it is known that there are multi-synaptic anatomical connections between central au...
