Similar to the NINCDS-ADRDA Alzheimer's Criteria are the DSM-IV-TR criteria published by the American Psychiatric Association. [3] At the same time the advances in functional neuroimaging techniques such as PET or SPECT that have already proven their utility to differentiate Alzheimer's disease from other possible causes, [4] have led to proposals of revision of the NINCDS-ADRDA criteria that ...
PET imaging with 18F-FDG takes advantage of the fact that the brain is normally a rapid user of glucose. Standard 18F-FDG PET of the brain measures regional glucose use and can be used in neuropathological diagnosis. Example: Brain pathologies such as Alzheimer's disease greatly decrease brain metabolism of both glucose and oxygen in tandem ...
Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
Due to low accuracy, the C-PIB-PET scan is not recommended as an early diagnostic tool or for predicting the development of AD when people show signs of mild cognitive impairment (MCI). [160] The use of 18 F-FDG PET scans, as a single test, to identify people who may develop Alzheimer's disease is not supported by evidence. [161]
Pre-dementia or early-stage dementia (stages 1, 2, and 3). In this initial phase, a person can still live independently and may not exhibit obvious memory loss or have any difficulty completing ...
The first research criteria for FTD, "Clinical and neuropathological criteria for frontotemporal dementia. The Lund and Manchester Groups", was developed in 1994. The clinical diagnostic criteria were revised in the late 1990s, when the FTD spectrum was divided into a behavioral variant, a nonfluent aphasia variant, and a semantic dementia ...
The first PiB study of a human subject with a clinical diagnosis of Alzheimer's disease was conducted by Henry Engler in February, 2002, at Uppsala University. PET scans showed that the compound was retained in areas of the cerebral cortex known to contain significant amyloid deposits from post-mortem examinations. The initial human study of ...
The CDC said 1.7% of adults ages 65 to 74 reported a dementia diagnosis, a rate that increased with age. For those ages 75 to 84, the reported dementia rate was 5.7%.
