Abstract

The presence of corpora amylacea (CA) in the CNS is associated with both normal aging and neurodegenerative conditions including Alzheimer's disease (AD) and vascular dementia (VaD). CA are spherical bodies ranging in diameter (10-50 μm) and whose origin has been documented to be derived from both neural and glial sources. CA are reported to be primarily composed of glucose polymers, but approximately 4% of the total weight of CA is consistently composed of protein. CA are typically localized in the subpial, periventricular and perivascular regions within the CNS. The presence of CA in VaD has recently been documented and of interest was the localization of CA within the hippocampus proper. Despite numerous efforts, the precise role of CA in normal aging or disease is not known. The purpose of this mini review is to highlight the potential function of CA in various neurodegenerative disorders with an emphasis on the potential role if any these structures may play in the etiology of these diseases.
