Etymology: "Bradykinesias" is the plural of "bradykinesia," a medical term for slowness of movement. The word is built from two Greek-derived parts: "brady-," from Greek "bradys," meaning "slow," and "-kinesia," from Greek "kinēsis," meaning "movement." The second element also appears in "hyperkinesia" (excessive movement) and in "akinesia" (absence of movement), so the same building blocks describe a whole range of motor conditions. The "-kinesia" ending is a suffix that clinicians and scientists have used for a long time to name conditions affecting movement, which is why the word reads as a technical coinage rather than an everyday term. "Bradykinesia" belongs to that modern medical vocabulary: it names a symptom that doctors observe and measure, most often in conditions such as Parkinson's disease, where slowed movement is one of the core features.
