axonal water fraction
|
BMO_0000117 |
[Axonal water fraction (AWF) is a metric used in diffusion MRI (dMRI) to characterize the microstructural properties of white matter in the brain. It quantifies the proportion of water molecules associated specifically with the axonal compartments within white matter tissue.] |
wake after sleep onset
|
EFO_0803363 |

sleep efficiency
|
EFO_0803364 |
[A relative measurement of the time spent asleep to the total time spent in bed.] |
fractional anisotropy
|
BMO_0000119 |
[Fractional Anisotropy (FA) is a metric derived from diffusion tensor imaging (DTI), a magnetic resonance imaging (MRI) technique used to study the microstructural organization of tissues, particularly white matter in the brain. FA quantifies the degree of anisotropy of water diffusion within tissue. In white matter, water molecules tend to diffuse more easily along the direction of the fiber tracts (axonal bundles) than perpendicular to them. FA values range from 0 to 1, where higher values indicate greater directionality or organization of the tissue microstructure, typically reflecting intact white matter tracts.] |
sleep duration
|
EFO_0005271 |
[duration of sleep, measured either via a self-reporting questionnaire, interview or through obversation in a sleep lab] |
clusterin
|
PR_000005615 |
[A protein that is a translation product of the human CLU gene or a 1:1 ortholog thereof.] |
sleep time
|
EFO_0005274 |
[measurement of the time at which sleep begins] |
Natriuretic Peptide, Brain
|
OMIT_0020024 |
[A PEPTIDE that is secreted by the BRAIN and the HEART ATRIA, stored mainly in cardiac ventricular MYOCARDIUM. It can cause NATRIURESIS; DIURESIS; VASODILATION; and inhibits secretion of RENIN and ALDOSTERONE. It improves heart function. It contains 32 AMINO ACIDS.] |
sleep quality
|
EFO_0005272 |
[quantification of some aspect of sleep quality, such as number of awakenings during a sleep interval or time taken to get to sleep. Sleep quality can be evaluated either through self-reporting, observation in a sleep lab or using a sleep monitoring device] |
sleep depth
|
EFO_0005273 |
[self-reported assessment of how difficult an individual is to wake] |
snoring measurement
|
EFO_0008341 |
[quantification of some aspect of snoring such as frequency or severity] |
high-density lipoprotein cholesterol
|
CHEBI_47775 |
[Cholesterol esters and free cholesterol which are contained in or bound to high-density lipoproteins (HDL).] |
waist circumference
|
EFO_0004342 |
[The measurement around the body at the level of the ABDOMEN and just above the hip bone. The measurement is usually taken immediately after exhalation.] |
hippocampal volume
|
EFO_0005035 |
[Measurement of the volume of the hippocampus] |
amyloid deposition
|
BMO_0000120 |
[Amyloid deposition refers to the accumulation of amyloid proteins, specifically amyloid-beta (Aβ) peptides, in various tissues and organs throughout the body. In the context of neuroscience and neuroimaging, amyloid deposition commonly refers to the accumulation of Aβ plaques in the brain, which is a pathological hallmark of Alzheimer's disease (AD) and some other neurodegenerative disorders.
In AD, abnormal accumulation of Aβ peptides leads to the formation of plaques, which disrupt neuronal function and contribute to neurodegeneration. Imaging techniques such as positron emission tomography (PET) using radioligands targeting Aβ can detect and quantify amyloid deposition in the brain.] |
NT-proBNP measurement
|
EFO_0004745 |
[Is a quantification of NT-proBNP (N-terminal prohormone of brain natriuretic peptide) which is associated with acute congestive heart failure.] |
tau deposition
|
BMO_0000121 |
[Tau deposition refers to the accumulation of abnormal tau protein aggregates in the brain, which is a characteristic feature of several neurodegenerative disorders, including Alzheimer's disease (AD), frontotemporal dementia (FTD), and certain forms of Parkinson's disease (PD), among others.
In neuroimaging, techniques such as positron emission tomography (PET) using radioligands targeting tau can visualize and quantify tau deposition in the brain. These imaging methods enable researchers and clinicians to detect the presence of abnormal tau aggregates and assess their distribution and severity.] |
mean diffusivity
|
BMO_0000122 |
[Mean diffusivity (MD) is a metric derived from diffusion-weighted magnetic resonance imaging (DW-MRI) data. It quantifies the average magnitude of water molecule diffusion within a particular tissue or region of interest.
MD is calculated based on the diffusion tensor, which characterizes the rate and directionality of water diffusion in tissue. Unlike fractional anisotropy (FA), which measures the degree of diffusion directionality, MD represents the overall magnitude of diffusion regardless of direction.] |
