The association of motor reserve and clinical progression in Parkinson’s disease Open
The baseline MR of PD patients were associated with motor and non-motor symptoms and can predicted disease prognosis, suggesting that the initial MR in PD would be associated with the individual's capacity to cope with neurodegenerative pr…

Correlation research of susceptibility single nucleotide polymorphisms and the severity of clinical symptoms in attention deficit hyperactivity disorder Open
Objective To analyze the correlation between susceptibility single nucleotide polymorphisms (SNPs) and the severity of clinical symptoms in children with attention deficit hyperactivity disorder (ADHD), so as to supplement the clinical sig…

Long-Range White Matter Microstructural Alterations in Drug-Naive Children with Attention Deficit Hyperactivity Disorder: A Tract-Based Spatial Statistics Study Open
Background Microstructural changes might underlie white matter (WM) pathology in attention deficit hyperactivity disorder (ADHD). To investigate WM alterations, particularly the changes in long-range fibers, in drug-naive children with ADH…

Altered Variability and Concordance of Dynamic Resting-State fMRI Indices in Patients With Attention Deficit Hyperactivity Disorder Open
Objective: Attention deficit hyperactivity disorder (ADHD) is a commonly diagnosed neuropsychiatric disorder in children, which is characterized by inattention, hyperactivity and impulsivity. Using resting-state functional magnetic resonan…

Different effects of the DRD4 genotype on intrinsic brain network connectivity strength in drug-naïve children with ADHD and healthy controls Open
The dopamine D4 receptor gene (DRD4) has been consistently reported to be associated with attention-deficit/hyperactivity disorder (ADHD). Recent studies have linked DRD4 to functional connectivity among specific brain regions. The current…

Correlation analysis between CT findings and duration of initial symptoms in young and middle-aged patients with novel coronavirus pneumonia Open
Objective: To retrospectively analyze the correlation between CT findings and duration of initial symptoms in young and middle-aged patients with novel coronavirus pneumonia.Materials and methods: From January 17, 2020 to February 4, 2020,…
View article: Exploring white matter functional networks in children with attention-deficit/hyperactivity disorder
Exploring white matter functional networks in children with attention-deficit/hyperactivity disorder Open
Attention-deficit/hyperactivity disorder has been identified to involve the impairment of large-scale functional networks within grey matter, and recent studies have suggested that white matter, which also encodes neural activity, can mani…
View article: Effects of the 2-Repeat Allele of the DRD4 Gene on Neural Networks Associated With the Prefrontal Cortex in Children With ADHD
Effects of the 2-Repeat Allele of the DRD4 Gene on Neural Networks Associated With the Prefrontal Cortex in Children With ADHD Open
Objective: Genetic variation, especially polymorphism of the dopamine D4 receptor gene (DRD4), has been linked to deficits in self-regulation and executive functions and to attention deficit hyperactivity disorder (ADHD), and is related to…
View article: Disrupted Control-Related Functional Brain Networks in Drug-Naive Children with Attention-Deficit/Hyperactivity Disorder
Disrupted Control-Related Functional Brain Networks in Drug-Naive Children with Attention-Deficit/Hyperactivity Disorder Open
Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disease featuring executive control deficits as a prominent neuropsychological trait. Executive functions are implicated in multiple sub-networks of the brain; …
