Ekbom’s syndrome
a sense of uneasiness, twitching, or restlessness that occurs in the legs when at rest (i.e., sitting or lying) or after retiring for the night. The cause is unknown, but it has been associated with a deficiency of iron, vitamin B12, or folic acid; nerve damage associated with rheumatoid arthritis, kidney failure, or diabetes; and the use of such drugs as lithium, anticonvulsants, antidepressants, and beta blockers. Also called restless-legs syndrome; tachyathetosis; Wittmaack–Ekbom syndrome. [Karl-Axel Ekbom (1907–1977), Swedish physician]
