White matter involvement in idiopathic Parkinson disease: a diffusion tensor imaging study.
BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) offers a unique window on the connectivity changes, extending beyond the basal ganglia, which accompany the cognitive symptoms of Parkinson disease (PD). The primary purpose of this study was to assess the microstructural damage to cerebral white matter occurring in idiopathic PD. MATERIALS AND METHODS Our sample included patients with PD ...
متن کاملEvaluation of White Matter Tracts in Autistic Individuals: A Review of Diffusion Tensor Imaging Studies
Introduction: Many cognitive and social deficits in autism are caused by abnormal functional connections between brain networks, which are manifested by impaired integrity of white matter tracts. White matter tracts are like the "highways" of the brain, which allow fast and efficient communication in different areas of the brain. The purpose of this article is to review the results of autism st...
متن کاملWhite matter microstructure changes in the thalamus in Parkinson disease with depression: A diffusion tensor MR imaging study.
BACKGROUND AND PURPOSE Depression occurs frequently in PD; however the neural basis of depression in PD remains unclear. The aim of this study was to characterize possible depression-related white matter microstructural changes in the thalamus of patients with DPD compared with those with NDPD. MATERIALS AND METHODS FA and MD maps from DTI were obtained in 14 patients with DPD and 18 patients...
متن کاملGray and white matter changes in Alzheimer's disease: a diffusion tensor imaging study.
PURPOSE To investigate microstructural changes in cortical and white matter pathways in patients with Alzheimer's disease using diffusion tensor imaging (DTI). MATERIALS AND METHODS Measures of mean diffusivity (MD) and fractional anisotropy (FA) were compared in the brains of 13 Alzheimer's disease (AD) patients and a group of 13 aged-matched control participants employing an optimized DTI t...
متن کاملWhite Matter Changes in OCD Revealed by Diffusion Tensor Imaging.
UNLABELLED IntroductionThe aim of this study was to investigate white matter (WM) abnormalities in obsessive-compulsive disorder (OCD) and its relationship to severity of obsessive-compulsive symptoms. METHODS Conventional and diffusion tensor imaging were acquired in nine patients with OCD and nine gender- and age-matched healthy volunteers. Changes in fractional anisotropy (FA) and mean dif...
