Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. ...
Since pseudodementia does not cause deterioration of the brain, brain scans can be used to visualize potential deterioration associated with dementia. Investigations such as PET and SPECT imaging of the brain show reduced blood flow in areas of the brain in people with Alzheimer's disease (AD), the most common type of dementia, compared with a ...
Small cell lung cancer is a particularly aggressive cancer more common in smokers and is associated with anti-Hu encephalitis. Neuroblastoma is a cancer more frequently affecting children, and despite the relatively low rates of anti-Hu among children with neuroblastoma, these are the most likely children to have anti-Hu associated encephalitis.
Some plaques occur in the brain as a result of aging, but large numbers of plaques and neurofibrillary tangles are characteristic features of Alzheimer's disease. [5] The plaques are highly variable in shape and size; in tissue sections immunostained for Aβ, they comprise a log-normal size distribution curve, with an average plaque area of 400 ...
Vascular dementia can be caused by ischemic or hemorrhagic infarcts affecting multiple brain areas, including the anterior cerebral artery territory, the parietal lobes, or the cingulate gyrus. [5] On rare occasion, infarcts in the hippocampus or thalamus are the cause of dementia. [ 12 ]
Yellow softening is the third type of cerebral softening. As its name implies, the affected softened areas of the brain have a yellow appearance. This yellow appearance is due to atherosclerotic plaque build-up in interior brain arteries coupled with yellow lymph around the choroid plexus, which occurs in specific instances of brain trauma.

This contrasts with the pseudofusion beat wherein the pacemaker impulse does not affect the complex of the natural beat of the heart. Pseudofusion beats are normal. Rare or isolated fusion beats caused by pacemakers are normal as well, but if they occur too frequently may reduce cardiac output and so can require adjustment of the pacemaker. [3]
Creutzfeldt–Jakob disease (CJD), also known as subacute spongiform encephalopathy or neurocognitive disorder due to prion disease, is a fatal neurodegenerative disease. [4] [1] Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances. [4]
