biomarker
A measurable biological indicator of normal or pathological processes in neurological conditions.
Full Definition
In neuroinformatics, a biomarker is an objective, quantifiable characteristic of biological processes that can be measured accurately and reproducibly. Neurological biomarkers may include brain volume measurements, protein levels in cerebrospinal fluid, genetic variants, or imaging-derived metrics. These markers are essential for early detection, monitoring disease progression, and evaluating treatment responses in neurological disorders.
Usage
Usage note: Write as one word, not 'bio-marker' or 'bio marker'.
