Although this pattern of brain shrinkage suggests Alzheimer's, it is variable and a brain scan is insufficient for a diagnosis.

This is due to the fact that brain tissue from patients with the disease can only be studied after the person's death.
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 ...

Increasingly it is also being used for quantitative research studies of brain disease and psychiatric ...
Some are caused by brain injuries (e.g., concussion), treatable illnesses (e.g., depression), or chronic conditions (e.g., Alzheimer's disease). Memory disorders are often classified according to ...
