wiki 項目を開く25-hydroxyvitamin DThe vitamin D blood test most often used to assess vitamin D status.wiki 項目を開くAlkaline phosphataseAn enzyme signal that can come from bone, liver, bile ducts, or other tissues.wiki 項目を開くBMDBone mineral density: a measurement result, not a standalone diagnosis.wiki 項目を開くBone scanA nuclear medicine imaging test used in selected bone disease and metastasis contexts.wiki 項目を開くCRPAn inflammation marker that can support infection/inflammation context but cannot identify the cause alone.wiki 項目を開くCTXA bone resorption marker that is timing-sensitive and context-sensitive.wiki 項目を開くCultureA microbiology clue used to identify organisms in infection contexts.wiki 項目を開くDXA / DEXAA low-dose X-ray method used to estimate bone mineral density, usually at the hip and spine.wiki 項目を開くeGFR / kidney functionKidney function context that can change phosphate, calcium, PTH, vitamin D, and bone turnover meaning.wiki 項目を開くESRA nonspecific inflammation marker sometimes used with CRP and other clues.wiki 項目を開くFracture and fall historyPast low-trauma fractures and falls often matter more than any single scan number.wiki 項目を開くFRAXA fracture-risk model clinicians may use; BioConst references the concept but does not embed a calculator.wiki 項目を開くMRIAn imaging method that can show marrow, soft tissue, early osteonecrosis, infection, or occult fracture context.wiki 項目を開くP1NPA bone formation marker used as context, not as a standalone diagnosis.wiki 項目を開くPhosphateA blood electrolyte tied to bone mineral, kidney function, PTH, and vitamin D context.wiki 項目を開くPTHParathyroid hormone: a calcium-phosphate control signal that must be read with calcium and kidney context.wiki 項目を開くSerum calciumBlood calcium is tightly regulated and does not directly tell how much calcium is in bone.wiki 項目を開くT-scoreA comparison between measured BMD and a young-adult reference database, mainly used in older adult contexts.wiki 項目を開くVertebral fracture assessmentA low-dose lateral spine image often performed on a DXA system to look for vertebral compression fractures.wiki 項目を開くX-rayA basic imaging method for bone shape, fractures, sclerosis, lytic change, and deformity context.wiki 項目を開くZ-scoreA comparison between measured BMD and an age-matched reference group.

脳の変数

wiki 項目を開くActivities of daily livingEveryday function is the practical boundary between ordinary forgetfulness, MCI, and dementia-level impairment.wiki 項目を開くBeta-amyloidA protein fragment that can accumulate as plaques in Alzheimer disease and is targeted by some approved antibodies.wiki 項目を開くARIAAmyloid-related imaging abnormalities, including edema or bleeding findings that can occur with anti-amyloid treatment.wiki 項目を開くAnti-amyloid antibodiesA drug class targeting amyloid beta in certain early Alzheimer disease contexts.wiki 項目を開くBrain atrophyLoss of brain volume that can become widespread in later Alzheimer disease as neurons die and networks fail.wiki 項目を開くCognitive testingStructured tests of memory, thinking, language, judgment, and other brain functions.wiki 項目を開くDepression, delirium, and medication contextMood, acute confusion, medicines, and medicine interactions can change memory and thinking, especially in older adults.wiki 項目を開くEpisodic memoryMemory for personal events and experiences, often the type people mean when they say they are becoming forgetful.wiki 項目を開くHearing and vision inputSensory loss can affect brain health and daily cognition because less reliable input changes how people function and remember.wiki 項目を開くHippocampus / entorhinal memory networkA memory-related brain network central to forming new memories and often affected early in Alzheimer disease.wiki 項目を開くMCIA clinical category for memory or thinking problems beyond peers, with daily independence mostly preserved.wiki 項目を開くSleep and memorySleep supports brain function, and NIA lists seven to nine hours as a general older-adult brain-health target.wiki 項目を開くSynaptic plasticityThe ability of neuronal connections to change strength with experience; a core mechanism discussed in memory biology.wiki 項目を開くTauA microtubule-related protein that can form neurofibrillary tangles in Alzheimer disease.wiki 項目を開くVascular risk and brain healthBlood pressure, diabetes, cholesterol, stroke, and vascular disease can affect cognitive health and dementia risk.
