Magnetic resonance imaging (MRI) studies in children with maltreatment-related posttraumatic stress disorder (PTSD) have demonstrated smaller corpus callosum area, with the greatest magnitude of change in posterior portions of the corpus callosum. The purpose of this study was to measure corpus callosum area in adult female patients with childhood abuse-related PTSD and comparison subjects. MRI...
PURPOSE To determine whether the MR findings of callosal dysgenesis suggest that the partially formed corpus callosum in humans is the result of arrested growth or delayed continued development. METHODS The MR scans of 25 patients with callosal dysgenesis were reviewed to determine whether the observed corpus callosum corresponded to the form and position of a portion of a normal corpus callo...
BACKGROUND Atrophy of the corpus callosum in the absence of primary white matter degeneration reflects loss of intracortical projecting neocortical pyramidal neurons in Alzheimer disease (AD). OBJECTIVES To determine individual rates of atrophy progression of the corpus callosum in patients with AD and to correlate rates of atrophy progression with clinical disease severity and subcortical di...
he corpus callosum is the largest white matter tract connecting the 2 cerebral hemispheres. Its embryologic development has been studied extensively.1 At 11 to 12 weeks’ gestation, axons begin to cross the lamina terminalis to form the corpus callosum. Development generally proceeds anterior to posterior (from genu to body to splenium) with the exception of the rostrum, which forms last. The ma...
As its integrity is essential for cognitive performances, it is surprising that there are no adequate studies in terms of the corpus callosum changes in diabetic patients. Consequently, the aim of this paper is to show how corpus callosum craniocaudal dimensions are changed by diabetes mellitus. The study was designed as a retrospective investigation. The study group included 50 patients who ha...
BACKGROUND Previous research has indicated that corpus callosum atrophy is associated with global cognitive decline in neurodegenerative diseases, but few studies have investigated specific cognitive functions. OBJECTIVE To investigate the role of regional corpus callosum atrophy in mental speed, attention and executive functions in subjects with age-related white matter hyperintensities (WMH...
OBJECTIVE The aim of this study was to investigate whether volumes of the corpus callosum could predict a response to antiepileptic drugs in patients with newly diagnosed focal epilepsy. METHODS Fifty-three patients with newly diagnosed focal epilepsy of unknown etiology and healthy subjects were enrolled in this study. First, we analyzed the differences in the volumes of the corpus callosum ...
