This damage can be focal, or restricted to a single area of the brain, or diffuse, affecting more than one region of the brain. (encyclopedia.com)
Diffuse brain damage associated with closed head injury may result from back-and-forth movement of the brain against the inside of the bony skull. (encyclopedia.com)
Because of the location of these prominences and the position of the brain within the skull, the frontal lobes (behind the forehead) and temporal lobes (underlying the temples) are most susceptible to this type of diffuse damage. (encyclopedia.com)
Diffuse axonal injury, or shear injury, may follow contrecoup injury even if there is no damage to the skull or obvious bleeding into the brain tissue. (encyclopedia.com)

Although the association between GCIP and brain atrophy in relapsing-remitting MS is impressive, the association in progressive MS, particularly secondary progressive MS, appears to be exceptional," Dr. Saidha stated. (medscape.com)
The relationship between GCIP and brain atrophy was affected by history of optic neuritis, which reduced the strength of the correlation, especially in the relapsing-remitting population. (medscape.com)

An MRI or 'magnetic resonance imaging' scan uses strong magnetic fields and radio waves to take detailed photos of the brain or spinal cord. (msif.org)

A key question is whether it is just the decrease in oxygen to the brain that is causing these white matter changes or whether the virus is itself attacking the white matter," says MGH neuroradiologist Otto Rapalino, MD, who shares first authorship with Harvard-MGH postdoctoral research fellow Akila Weerasekera, PhD.
