Voxel-based morphometry (VBM) studies have provided cumulative evidence of gray matter (GM) atrophy in patients with progressive supranuclear palsy (PSP) relative to healthy controls (HC). However, not all findings have been entirely concordant. Herein, we performed a quantitative meta-analysis study in order to consistently quantify GM anomalies in PSP. We conducted a systematic search for VBM studies of PSP patients and HC using PubMed and Embase databases from January 2000 to May 2012. Meta-analysis of these VBM studies was performed using a newly improved voxel-based meta-analytic technique, effect-size signed differential mapping. A total of 9 cross-sectional VBM studies that involved 143 PSP patients and 216 HC subjects met the inclusion criteria. Considerable regional GM volume decrease was detected in the thalamus, basal ganglia, midbrain, insular cortex, and frontal cortex. These findings remained largely unchanged following jackknife sensitivity analyses. The present meta-analysis provided evidence of PSP-specific GM atrophy. This finding might help contribute to our understanding of the neurobiological basis underlying PSP.

Childhood abuse represents one of the most potent risk factors for the development of psychopathology during childhood, accounting for 30-60% of the risk for onset. While previous studies have separately associated reductions in gray matter volume (GMV) with childhood abuse and internalizing psychopathology (IP), it is unclear whether abuse and IP differ in their structural abnormalities, and which GMV features are related to abuse and IP at the individual level. In a pooled multisite, multi-investigator sample, 246 child and adolescent females between the ages of 8-18 were recruited into studies of interpersonal violence (IPV) and/or IP (i.

Background: Objective Subtle Cognitive Decline (obj-SCD) can be identified through standardized neuropsychological tests and may precede the development of Mild Cognitive Impairment (MCI). Nevertheless, current clinical and research criteria lack a standardized protocol for identifying obj-SCD. This study introduces cutting-edge sensitive methods to characterize obj-SCD, defined through Alzheimer's disease (AD) biomarker-based longitudinal cognitive performance in episodic memory.

Background: Recent international work suggests that more precise subtyping within frontotemporal dementia (FTD) syndromes leads to better prediction of pathology, supporting individualized disease-specific treatments. Recent studies emphasize that identification of one such subtype, semantic behavioral variant FTD (sbvFTD), relies in part on measuring emotion recognition abilities.
Method: In order to evaluate the effectiveness of current tools, we compared the brief video-based Dynamic Affect Recognition Test (DART) against the TASIT Emotion Evaluation (EET) and Comprehensive Affect Testing System Affect Matching tests.

Objective: Peripheral nerve injury results in functional alterations of the corresponding active brain areas, which are closely related to functional recovery. Whether such functional plasticity induces relative anatomical structural changes remains to be investigated.
Methods: In this study, we investigated the changes in brain cortical thickness in patients with facial paralysis following neurorrhaphy treatment at different follow-up times.

Introduction: This study investigated the cortical and subcortical gray matter volume (GMV) and cognitive impairment (CI) in patients with Parkinson's disease (PD).
Methods: In this study, T1-weighted magnetic resonance imaging of the cortex and subcortex was conducted on 92 individuals diagnosed with PD and 92 healthy controls (HCs). PD patients were divided into three groups: PD with normal cognition (PD-NC, = 21), PD with mild CI (PD-MCI, = 43), and PD with severe CI (PD-SCI, = 28).
