Article Abstract
Objective: To determine whether baseline cerebral atrophy can predict the rate of future chronic subdural hematoma (CSDH) after head trauma and compare indirect markers of brain atrophy with volumetric analysis of computed tomography (CT).
Methods: Single institution case-control study involving 1,476 patients who visited our hospital after head trauma from January 2009 to December 2014. Forty-one patients with delayed CSDH were identified and age, gender matched 41 patients were selected as control group. Both volumetric analyze on CT and Evans index, frontal horn index, bicaudate ratio, sylvian fissure ratio and cortical atrophy scale of 82 patients were estimated by different raters and relationship of those factors with CSDH was analyzed.
Results: Every indirect indices except cortical atrophy scale were not enough to give a good estimate of CSDH. Brain atrophy and cortical atrophy scale were predisposing factors of CSDH on multivariate analysis with statistical significance.
Conclusion: Brain atrophy was a potential prognostic factor of CSDH after trauma. In practice, patients with a value of cortical atrophy scale over moderate grade needed more attention for CSDH.

Background: The relationships between white matter microstructure, cortical atrophy, and cognitive function in cerebral small vessel disease (CSVD)-related white matter hyperintensities (WMHs) patients are unclear.
Methods: 71 right-handed WMHs patients (mild, n=23; moderate, n=27; severe, n=21) and 35 healthy controls were included. Tract-based spatial statistics (TBSS) assessed microstructure via fractional anisotropy (FA) and mean diffusivity (MD).

Compared with more typical late-onset Alzheimer's disease (AD), the mechanisms of young-onset AD (YOAD; age of symptom onset <65 years) remain less understood. Using resting-state functional MRI data and dynamic causal modeling techniques, Sacu et al. demonstrate that individuals with YOAD (amnestic AD or posterior cortical atrophy) exhibit alterations in effective (i.

Introduction: Antisocial behaviors occur in dementia, but the underlying neurocognitive mechanisms remain underexplored. We administered a decision-making task measuring patients' harm aversion by offering options to shock themselves or another person in exchange for money, hypothesizing that task performance would relate to antisocial behaviors and ventromedial/orbitofrontal cortex (vmPFC/OFC) atrophy.
Methods: Among 43 dementia patients (n = 23 behavioral variant frontotemporal dementia [bvFTD], n = 20 Alzheimer's disease [AD]), we used linear regressions to measure relationships between harm aversion and antisocial behavior, psychopathic personality traits, socioemotional functions, and vmPFC/OFC cortical thickness, controlling for age, sex, and cognitive dysfunction.

Background: Frontotemporal dementia (FTD) encompasses diverse clinical phenotypes, primarily characterized by behavioral and/or language dysfunction. A newly characterized variant, semantic behavioral variant FTD (sbvFTD), exhibits predominant right temporal atrophy with features bridging behavioral variant FTD (bvFTD) and semantic variant primary progressive aphasia (svPPA). This study investigates the longitudinal structural MRI correlates of these FTD variants, focusing on cortical and subcortical structural damage to aid differential diagnosis and prognosis.

Patients with Duchenne muscular dystrophy (DMD) may experience neurobehavioral and cognitive concerns, including psychiatric symptoms, due to the absence of full-length dystrophin (Dp427), frequently accompanied by deficiencies in shorter isoforms. The lack of dystrophin affects neurophysiological processes from the uterine phase, impacting neural circuitry in brain regions such as the prefrontal cortex, hippocampus, and cerebellum. This leads to reduced inhibitory GABAergic transmission and altered hippocampal glutamatergic signaling.
