Mode of Anisotropy Reveals Global Diffusion Alterations in Attention-Deficit/Hyperactivity Disorder.
OBJECTIVE Diffusion tensor imaging (DTI) can identify structural connectivity alterations in attention-deficit/hyperactivity disorder (ADHD). Most ADHD DTI studies have concentrated on regional differences in fractional anisotropy (FA) despite its limited sensitivity to complex white matter architecture and increasing evidence of global brain differences in ADHD. Here, we examine multiple DTI m...
متن کاملEvaluation of Diffusion Anisotropy and Diffusion Shape in Grading of Glial Tumors
Background: The most common primary tumors of brain are gliomas. Grading of tumor is vital for designing proper treatment plans. The gold standard choice to determine the grade of glial tumor is biopsy which is an invasive method.Objective: In this study, we try to investigate the role of fractional anisotropy (diffusion anisotropy) and linear anisotropy ...
متن کاملDiffusion tensor imaging reveals white matter abnormalities in Attention-Deficit/Hyperactivity Disorder.
The specific brain structures or neural mechanisms underlying dysfunction in individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) are not well established, particularly in regard to white matter (WM). Diffusion tensor imaging (DTI) was used to investigate WM in 12 adolescent males diagnosed with ADHD only and 12 typically developing controls (group matched; mean age=15.64 years, SD=...
متن کامل[Alterations in social reciprocity in attention-deficit hyperactivity disorder].
OBJECTIVE Social interactions in children with attention deficit-hyperactivity disorder (ADHD) are inappropriate and such social problems may originate from a failure to attend to the appropriate cues of affect. The present study aimed to determine the factors predictive of social reciprocity in ADHD and their relationship to sociodemographics. MATERIALS AND METHODS Participants were required...
متن کاملDefault mode network subsystem alterations in obsessive-compulsive disorder.
BACKGROUND Although neurobiological models of obsessive-compulsive disorder (OCD) traditionally emphasise the central role of corticostriatal brain regions, studies of default mode network integrity have garnered increasing interest, but have produced conflicting results. AIMS To resolve these discrepant findings by examining the integrity of default mode network subsystems in OCD. METHOD C...
