Cerebral oedema and the water content of normal white matter.
The distribution of the increment of fluid in the human brain in cerebral oedema is not uniform. Obviously, cerebral oedema is often local, being present in the vicinity of a focal oedema-producing lesion such as a metastatic carcinomatous nodule. Of greater significance is the tendency to involve white matter with great severity, while sparing or almost sparing the adjacent gray matter. These ...
متن کاملCerebral white matter lesions, retinopathy, and stroke.
and Stroke To the Editor: I read with interest the study by Vermeer and colleagues1 on the risk of stroke associated with MRI-defined white matter lesions (WML) in the Rotterdam Scan Study. As cerebral MRI becomes a routine diagnostic test for widening indications of neurological disorders, this study provides further data on the clinical significance of these lesions in asymptomatic elderly pe...
متن کاملCerebral white matter deficiencies in pedophilic men.
The present investigation sought to identify which brain regions distinguish pedophilic from nonpedophilic men, using unbiased, automated analyses of the whole brain. T1-weighted magnetic resonance images (MRIs) were acquired from men who demonstrated illegal or clinically significant sexual behaviors or interests (n = 65) and from men who had histories of nonsexual offenses but no sexual offen...
متن کاملThe microvasculature of the cerebral white matter: arteries of the subcortical white matter.
The microvascular architecture of the human cerebral subcortical white matter was studied. Most of the subcortical arteries ran straight through the cortex, but upon entering the white matter, they began to coil, loop, and spiral. Vascular stains showed wide spaces between the adventitial sheaths and blood vessels. The blood vessels coiled, looped, and spiraled within these wide adventitial spa...
متن کاملMicrostructural white matter alterations in preclinical Alzheimer’s disease detected using free water elimination diffusion tensor imaging
Brain changes associated with Alzheimer's disease (AD) begin decades before disease diagnosis. While β-amyloid plaques and neurofibrillary tangles are defining features of AD, neuronal loss and synaptic pathology are closely related to the cognitive dysfunction. Brain imaging methods that are tuned to assess degeneration of myelinated nerve fibers in the brain (collectively called white matter)...
