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 ...
New research is contradicting previously held views that only neurons secret beta-amyloid that forms toxic plaques, a marker of Alzheimer's disease in the brain. The study points to another ...
The hallmark symptom of LATE is a progressive memory loss that predominantly affects short-term and episodic memory. [1] This impairment is often severe enough to interfere with daily functioning and usually remains the chief neurologic deficit, unlike other types of dementia in which non-memory cognitive domains and behavioral changes might be noted earlier or more prominently. [1]
Alzheimer’s, which affects memory and thinking skills, occurs when amyloids, naturally occurring proteins in the body, clump together to create amyloid plaques in the brain. Other types of ...
Studies have shown that PCA may be a variant of Alzheimer's disease (AD), with an emphasis on visual deficits. [2] [11] Although in primarily different, but sometimes overlapping, brain regions, both involve progressive neural degeneration, as shown by the loss of neurons and synapses, and the presence of neurofibrillary tangles and senile plaques in affected brain regions; this eventually ...
Binswanger's disease is a type of subcortical vascular dementia caused by white matter atrophy to the brain. However, white matter atrophy alone is not sufficient for this disease; evidence of subcortical dementia is also necessary.

Design draft for a reality orientation board used to help people with dementia or in post-operative delirium. The aim of cognition-oriented treatments, which include reality orientation and cognitive retraining is the restoration of cognitive deficits. Reality orientation consists in the presentation of information about time, place or person ...
