  2. NINCDS-ADRDA Alzheimer's Criteria - Wikipedia

    en.wikipedia.org/wiki/NINCDS-ADRDA_Alzheimer's...

    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 ...

  3. Posterior cortical atrophy - Wikipedia

    The cause of PCA is unknown, and there are no fully accepted diagnostic criteria for the disease. [2] [10] This is partially due to the gradual onset of PCA symptoms, their variety, the rare nature of the disease, and the younger age of onset typically 50–60 years. [20] In 2012, the first international conference on PCA was held in Vancouver ...

  4. Brain positron emission tomography - Wikipedia

    PET scanning is also used for diagnosis of brain disease, most notably because brain tumors, strokes, and neurondegenerative diseases (such as Alzheimer's disease and Parkinson's disease) all cause great changes in brain metabolism, which in turn causes detectable changes in PET scans. PET is probably most useful in early cases of certain ...

    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 variant. [20] The most recent revision of the clinical research criteria was by the International Behavioural Variant FTD Criteria Consortium in 2011. [50]

    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 ...

  8. Positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Positron_emission_tomography

    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.

    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%.
