Long-term cerebral white and gray matter changes after preeclampsia
OBJECTIVE To determine whether changes in cerebral structure are present after preeclampsia that may explain increased cerebrovascular risk in these women. METHODS We conducted a case control study in women between 5 and 15 years after either a preeclamptic or normotensive pregnancy. Brain MRI was performed. Analysis of white matter structure was undertaken using voxel-based segmentation of f...
متن کاملLong‐term white matter tract reorganization following prolonged febrile seizures
OBJECTIVE Diffusion magnetic resonance imaging (MRI) studies have demonstrated acute white matter changes following prolonged febrile seizures (PFS), but their longer-term evolution is unknown. We investigated a population-based cohort to determine white matter diffusion properties 8 years after PFS. METHODS We used diffusion tensor imaging (DTI) and applied Tract-Based Spatial Statistics for...
متن کاملLongitudinal changes in microstructural white matter metrics in Alzheimer's disease
BACKGROUND Alzheimer's disease (AD) is a progressive neurodegenerative disorder. Current avenues of AD research focus on pre-symptomatic biomarkers that will assist with early diagnosis of AD. The majority of magnetic resonance imaging (MRI) based biomarker research to date has focused on neuronal loss in grey matter and there is a paucity of research on white matter. METHODS Longitudinal DTI...
متن کاملLanguage-general and -specific white matter microstructural bases for reading
In the past decade, several studies have investigated language-general and -specific brain regions for reading. However, very limited research has examined the white matter that connects these cortical regions. By using diffusion tensor imaging (DTI), the current study investigated the common and divergent relationship between white matter integrity indexed by fractional anisotropy (FA) and nat...
متن کاملLong-term white matter changes after severe traumatic brain injury: a 5-year prospective cohort.
BACKGROUND AND PURPOSE Extensive white matter damage has been documented in patients with severe traumatic brain injury, yet how this damage evolves in the long term is not well understood. We used DTI to study white matter changes at 5 years after traumatic brain injury. MATERIALS AND METHODS There were 8 healthy control participants and 13 patients with severe traumatic brain injury who wer...
