Magnetic resonance imaging (MRI) scans to assess brain structure, connectivity, and the extent of white matter disease; Positron emission tomography (PET) scans to assess how well the brain uses glucose, and the extent of amyloid plaques and tau tangles. Neuropathological examination if a participant dies and has consented to autopsy.
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 ...
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). [159] 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.
“Amyloid PET scans are a proven tool and can be an important part of Alzheimer’s diagnosis and treatment,” Maria Carrillo, chief science officer of the Alzheimer’s Association, said in a ...
Imagine: You and your sister are 66-year-old twins on Medicare who share the same family history of Alzheimer’s disease, making an early diagnosis critical for long-term planning and preventive ...

A substantial proportion of patients with a positive florbetaben PET scan progressed to AD-dementia over a 2-year and 4-year time frame. At 4-year follow-up, 88% (21/24) of individuals with MCI and positive florbetaben uptake converted to clinical dementia due to AD, whereas none of 21 florbetaben-negative individuals with MCI experienced a ...
