Abstract

OBJECTIVES: We hypothesized that CSF neurofilament light (NFL) levels would be elevated in dementias with subcortical involvement, including vascular dementia (VaD), but less elevated in dementias primarily affecting gray matter structures, such as Alzheimer disease (AD), and that elevated CSF NFL would correlate with disease severity and shorter survival time irrespective of clinical diagnosis. METHODS: We included 3,356 individuals with dementia who had CSF NFL analyzed in our laboratory between 2005 and 2012. Clinical diagnoses and Mini-Mental State Examination (MMSE) scores were obtained from the Swedish Dementia Registry, and in selected cases (n = 478), date of death from the Swedish Mortality Registry. RESULTS: CSF NFL differed among clinical diagnoses, with the highest levels seen in frontotemporal dementia, VaD, and mixed AD and VaD. Early-onset AD (younger than 65 years) had the lowest levels. High CSF NFL correlated with low MMSE score and short survival time irrespective of diagnosis, and was also particularly evident in AD. CONCLUSIONS: CSF NFL differs among different neurodegenerative diseases and is especially high in dementias engaging subcortical brain regions, such as VaD and mixed AD and VaD, but also in frontotemporal dementia. The association of high CSF NFL levels with disease severity and short survival supports the notion that high CSF NFL levels indicate more aggressive disease processes.

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.
