Early functional and structural hippocampal impairment in a bilateral common carotid artery stenosis mouse model.
Animal Model Exp Med
January 2025
Department of Neurology, Tianjin Neurological Institute, Tianjin Medical University General Hospital, Tianjin, China.
Background: Subcortical ischemic vascular dementia (SIVD) is a common subtype of vascular dementia. Currently, the bilateral common carotid artery stenosis (BCAS) mouse model is the most suitable SIVD rodent model. In this study, we investigated the functional and structural impairments in the hippocampus 1 month after BCAS.

January 2025
Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.
Introduction: While cerebral amyloid angiopathy is likely responsible for intracerebral hemorrhage (ICH) occurring in superficial (grey matter, vermis) cerebellar locations, it is unclear whether hypertensive arteriopathy (HA), the other major cerebral small vessel disease (cSVD), is associated with cerebellar ICH (cICH) in deep (white matter, deep nuclei, cerebellar peduncle) regions. We tested the hypothesis that HA-associated neuroimaging markers are significantly associated with deep cICH compared to superficial cICH.
Patients And Methods: Brain MRI scans from consecutive non-traumatic cICH patients admitted to a referral center were analyzed for cSVD markers.
Abnormal resting-state brain network dynamics in toddlers with autism spectrum disorder.
Eur Child Adolesc Psychiatry
January 2025
National Center for Magnetic Resonance in Wuhan, State Key Laboratory of Magnetic Resonance Spectroscopy and Imaging, Wuhan Institute of Physics and Mathematics, Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences, Wuhan, 430071, China.
Emerging evidence suggests aberrant functional connectivity (FC) of brain networks in children, adolescents, and adults with autism spectrum disorder (ASD). However, little is known about alterations of dynamic FC in toddlers with ASD. The aim of this study was to investigate the characteristics of brain network dynamics in ASD toddlers.

Psychopharmacology (Berl)
January 2025
Edith Collins Centre for Translational Research in Alcohol, Drugs and Toxicology, Royal Prince Alfred Hospital, Sydney Local Health District, Sydney, NSW, Australia.
Rationale: Both topiramate and naltrexone have been shown to affect neural alcohol cue reactivity in alcohol use disorder (AUD). However, their comparative effects on alcohol cue reactivity are unknown. Moreover, while naltrexone has been found to normalize hyperactive localized network connectivity implicated in AUD, no studies have examined the effect of topiramate on intrinsic functional connectivity or compared functional connectivity between these two widely used medications.

J Behav Addict
January 2025
1Academy of Psychology and Behavior, Faculty of Psychology, Tianjin Normal University, Tianjin, 300387, China.
Background And Aims: Behavioral addictions (BAs) represent complex and multifaceted disorders often associated with maladaptive neural alteration. To deepen our understanding of the essence of BAs, this study focuses on the neural mechanisms underlying its three stages: reward seeking, self-control, and decision-making. The aim of the current meta-analysis is to investigate the brain regions and neural networks involved in BAs.
