Cortical thinning in chemotherapy-treated older long-term breast cancer survivors
AbstractCognitive decline is an increasing issue for cancer survivors, especially for older adults, as chemotherapy affects brain structure and function. The purpose of this single center study was to evaluate alterations in cortical thickness and cognition in older long-term survivors of breast cancer who had been treated with chemotherapy years ago. In this prospective cohort study, we enrolled 3 groups of women aged ≥ 65 years with a history of stage I-III breast cancer who had received adjuvant chemotherapy 5 to 15 years ago (chemotherapy group, C +), age-matched women with breast cancer but no chemotherapy ...

Relationship between visuoperceptual functions and parietal structural abnormalities in temporal lobe epilepsy
AbstractProgressive gray matter volume reductions beyond the epileptogenic area has been described in temporal lobe epilepsy. There is less evidence regarding correlations between gray and white matter volume changepres and multi-domain cognitive performance in this setting. We aimed to investigate correlations between volume changes in parietal structures and visuospatial performance in temporal lobe epilepsy patients. we performed a cross-sectional study comparing global and regional brain volume data from 34 temporal lobe epilepsy patients and 30 healthy controls. 3D T1-weighted sequences were obtained on a 3.0 T magnet...

Grey matter volume and its association with cognitive impairment and peripheral cytokines in excited individuals with schizophrenia
In conclusion, our results confirm GMV changes in excited patients with schizophrenia, and characterize the GMV as an important interface between inflammatory cytokines and cognitive impairment. Therefore, targeted anti-inflammatory adjuvant antipsychotic therapy may im prove cognitive function and volumetric brain abnormalities in these patients. (Source: Brain Imaging and Behavior)

Altered spatio-temporal state patterns for functional dynamics estimation in first-episode drug-naive major depression
AbstractPatients with major depressive disorder (MDD) display affective and cognitive impairments. Although MDD-associated abnormalities of brain function and structure have been explored in depth, the relationships between MDD and spatio-temporal large-scale functional networks have not been evaluated in large-sample datasets. We employed data from International Big-Data Center for Depression Research (IBCDR), and comparable 543 healthy controls (HC) and 314 first-episode drug-naive (FEDN) MDD patients were included. We used a multivariate pattern classification method to learn informative spatio-temporal functional state...

Brain microstructural abnormalities in patients with Wilson ’s disease: A systematic review of diffusion tenor imaging studies
ConclusionsDTI allows early detection of brain abnormalities associated with WD, prior to the occurrence of morphological brain changes by MRI. Correlations with treatment outcomes and clinical severity may provide objective and quantitative assessment of early and ongoing treatment response. Future studies are required to elucidate the role of DTI in WD clinical practice and find the most consistent DTI markers that may improve clinical outcome. (Source: Brain Imaging and Behavior)

Degree centrality and functional connections in presbycusis with and without cognitive impairments
AbstractPresbycusis is a major public issue that affecting elderly adults. However, the neural substrates between normal cognition and cognitive deficits in these patients need to be illustrated. 47 patients with presbycusis and 33 well-matched healthy controls were recruited in present study. Each subject underwent pure-tone audiometry (PTA), MRI scanning and cognition evaluations, then we found 22 patients with cognitive deficits and 25 patients with common cognition. We analyzed the Degree centrality (DC) characteristics among three groups, and try to recognize key nodes which contribute significantly. Subsequent functi...

Relationships between physical activity, healthy eating and cortical thickness in children and young adults
AbstractPrior neuroimaging studies have shown associations between healthy lifestyle factors and cortical thickness; however, results on the direction of this association have been inconsistent. While the majority of studies were performed in older adults within specific weight status categories, little has been reported in younger populations with a range of adiposity, including groups with healthy-weight, overweight, and obesity. Here we investigated relationships between indices of physical activity (PA) and healthy eating with cortical thickness in children and youth/young adults and examined whether these relationship...

Obsessive-compulsive symptoms and resting-state functional characteristics in pre-adolescent children from the general population
AbstractWhile functional brain characteristics of obsessive-compulsive disorder have been extensively studied, literature on network topology and subnetwork connectivity related to obsessive-compulsive symptoms (OCS) is sparse. Here we investigated the functional brain characteristics of OCS in children from the general population using a multiscale approach. Since we previously observed OCS-related differences in thalamus morphology, we also focused on the network participation of thalamic subregions. The study included 1701 participants (9 –12 years) from the population-based Generation R study. OCS were measured using...

Psychological resilience mediates the association of the middle frontal gyrus functional connectivity with sleep quality
AbstractPsychological resilience is characterized as the ability to recover from stress, which is essential for sleep quality. However, the neurological underpinnings of psychological resilience and the neural substrates of the links between psychological resilience and sleep quality in healthy brains remain not well understood. To address these issues, we adopted the method of resting-state functional connectivity (rs-FC) analysis in 144 young college students. The functional connectivity analysis indicated that psychological resilience was associated with the middle frontal gryus (MFG) functional connectivity, which main...

The experience of vertigo: A systematic review of neuroimaging studies
AbstractOur primary objective was to assess consistent activation and deactivation among healthy participants and patients reporting vertigo. Our secondary aim was to evaluate the influence of the stimulus and the direction of the perception of self-motion We realized a systematic review with an extensive data visualization. We included neuroimaging studies (e.g., functional magnetic resonance imaging [fMRI], positron emission tomography [PET] or near infrared spectroscopy [NIRS]) that have measured functional activity in human adults reporting vertigo and/or dizziness. We included 21 studies (n = 336 participants), ...

Trait related aberrant connectivity in clinically stable patients with schizophrenia: A seed based resting state fMRI study
In this study, we used a seed-based functional connectivity analysis to investigate brain networks in schizophrenia patients who are in the stable phase of their illness and assess functional connectivity using seeds in the lingual gyrus, the posterior cingulate, the right dorsolateral prefrontal cortex (dlPFC), the right anterior insula (rAI) and the right orbital frontoinsula. Twenty patients with schizophrenia in a stable phase of their illness (as defined by the course of illness and Signs and Symptoms of Psychotic Illness (SSPI) scores) and 20 age and sex-matched healthy controls underwent resting-state functional Mag...
