People with lower B12 levels also had slower processing speeds, an effect that the researchers found increased with age, and larger volumes of white matter hyperintensities, brain changes that are ...

Introduction. White matter hyperintensities (WMHs) are imaging abnormalities observed on T2-weighted MRI scans ().These abnormalities increase with age, with an estimated 90% of individuals over 65 ...

Occipital lobe. Symptoms include color blindness , hallucinations, inability to perceive more than one object at a time, and total blindness. Cerebral Cortex Is Gray Matter ...

A 78-year-old woman with a history of breast and lung cancers presented with confusion. MRI of the head revealed hyperintensities in the anterior and medial temporal lobes. A diagnosis was made.

Although there were no significant group differences in white matter hyperintensities in the frontal region, a significant direct correlation emerged between the severity of frontal periventricular ...

Recent research reveals that the brains of superagers are subtly different from those of their peers, which makes them 'resistant' to age-related cognitive decline.

Patients with immune-mediated thrombotic thrombocytopenic purpura (TTP) were found to have white matter damage in the frontal lobe and cingulate cortex that could affect short-term memory and ...

He said Bowers had extensive “white-matter hyperintensities,” which can be caused by a number of things, including migraines. He called the MRI “a normal brain MRI,” and not diagnostically ...

COVID-19 changes the white matter in the brain." Wong is currently the Canada Research Chair in Artificial Intelligence and Medical Imaging.

The CDI imaging of frontal-lobe white matter revealed a less restricted diffusion of water molecules in COVID-19 patients. At the same time, ...

Posterior reversible encephalopathy syndrome (PRES) 1,2 is an acute or subacute cerebral syndrome, the main manifestations of which are headache, encephalopathy, seizures, or visual disturbances ...

White matter refers to the vast network of nerve fibers connecting neurons in various brain regions. These lesions, or tissue injuries, could potentially lead to physical or cognitive problems.
