Cortical morphology alterations in non-COVID-19 post-infectious olfactory dysfunction

Scientific Reports
While COVID-19-associated olfactory dysfunction leads to gray matter (GM) structural alterations, it remains unclear whether these structural GM alterations are specific to COVID-19.

Voxel‐Based Morphometry and Voxel‐Based Relaxometry in Parkinsonian Variant of Multiple System Atrophy

Journal of Neuroimaging, 2010
ABSTRACTBACKGROUND AND PURPOSE Multiple system atrophy (MSA) is a progressive neurodegenerative disorder divided into a parkinsonian (MSA‐P) and a cerebellar variant. The purpose of this study was to assess regional brain atrophy and iron content using Voxel‐based morphometry (VBM) and Voxel‐based relaxometry (VBR) respectively, in MSA‐P. METHODS Using

Artificial intelligence in preclinical epilepsy research: Current state, potential, and challenges

Epilepsia Open, EarlyView.
Abstract Preclinical translational epilepsy research uses animal models to better understand the mechanisms underlying epilepsy and its comorbidities, as well as to analyze and develop potential treatments that may mitigate this neurological disorder and its associated conditions. Artificial intelligence (AI) has emerged as a transformative tool across

Neural Correlates of Congenital Amusia

Pediatric Neurology Briefs, 2006
Magnetic resonance T1-weighted images were analyzed, using voxel-based morphometry (VBM), to detect brain anatomical differences in two independent groups of adults with congenital amusia (or tone-deafness) compared to controls with normal pitch ...

Disrupted Brain Structure and Function in Alzheimer's Disease Patients With Behavioral and Psychological Symptoms

iNew Medicine, EarlyView.
ABSTRACT Objective Behavioral and psychological symptoms of dementia (BPSD) are highly prevalent in Alzheimer’s disease (AD), but the underlying mechanisms are unclear. This study aims to elucidate the neuropathological mechanisms underlying BPSD by investigating gray matter volume (GMV) and brain connectivity in AD patients with and without BPSD ...
