Abstract

Although the diagnosis of dementia still is primarily based on clinical criteria, neuroimaging is playing an increasingly important role. This is in large part due to advances in techniques that can assist with discriminating between different syndromes. Magnetic resonance imaging remains at the core of differential diagnosis, with specific patterns of cortical and subcortical changes having diagnostic significance. Recent developments in molecular PET imaging techniques have opened the door for not only antemortem but early, even preclinical, diagnosis of underlying pathology. This is vital, as treatment trials are underway for pharmacological agents with specific molecular targets, and numerous failed trials suggest that earlier treatment is needed. This article provides an overview of classic neuroimaging findings as well as new and cutting-edge research techniques that assist with clinical diagnosis of a range of dementia syndromes, with an emphasis on studies using pathologically proven cases.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Positron emission tomography has shortcomings for visualizing Aβ plaques in the brain, including radioligand use, limited spatial resolution, and higher cost.

    “Positron emission tomography has been employed to visualize Aβ plaques in the brain for the diagnosis of AD, 3 however it has obvious shortcomings, such as radioligand use, limited spatial resolution and higher cost.4”

    From Amyloid Plaque Imaging with a Targeted MRI Contrast Agent in a Transgenic Mouse Model of Alzheimer’s Disease (2022) · cites this paper as [3]

    In “Alzheimer’s Disease > Other Imaging Modalities in AD” (page not provided), the paper says amyloid PET detects cortical β-amyloid and identifies high cost and the need for a specialized PET center as limitations. It does not identify radioligand use or limited spatial resolution as shortcomings. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
