For many years, investigators have been puzzled by the weak to nonexistent correlation between the amount of neuritic plaque pathology in the human brain and the degree of clinical dementia. Recent advances in our understanding of the development of amyloid pathology have helped solve this mystery. Imaging technologies, including new amyloid imaging agents based on the chemical structure of histologic dyes, are now making it possible to track amyloid pathology along with disease progression in the living patient. This raises important issues regarding the development and testing of future therapeutic agents. The methods used to assess the pathology and classify stages of AD have been standardized and codified to provide a guide for clinicians. Standard measures of pathology refer to the density of neuritic amyloid plaques and neurofibrillary tangles of tau protein in affected brain regions. Deposits of tau protein are also present, although they are also found in a number of less common neurodegenerative diseases, notably in the absence of neuritic plaques. The neurofibrillary tangles in the different diseases have some distinctive morphological features and may exhibit a distinct composition of tau isoforms that differs from AD [ 1 ]. Development of a disease stage classification for AD has not been a simple process, nor is there complete consensus with the system s that are in place.

While older NHPs typically show small amounts of amyloid deposition, this is quite abeta amyloid compared to cases of AD [ - ].

Continued and expanded research on these devastating diseases is a National Institutes of Health top priority. For example, the fibrils can cause neuronal cell damage and inflammation. While this finding caused some initial interest, it resulted in a limited line of subsequent research because of the lack of specific markers to detect it in laboratories and the inability to reproduce the initial findings.

Abeta amyloid

The oligomers are toxic to nerve cells. A study has suggested that APP and its amyloid potential is of ancient origins, dating as far back as early deuterostomes. The glymphatic system clears metabolic waste from the mammalian brain, and in particular amyloid beta. Research suggests that soluble oligomeric forms of the amyloid beta may be causative agents in the development of Alzheimer's disease. The " amyloid hypothesis " — that the plaques are responsible for the pathology of Alzheimer's disease — is accepted by the majority of researchers, but is not conclusively established.
