Abstract

Periodic limb movements during sleep (PLMS) are frequently observed in the general population, although such movements may be associated with a variety of medical and neurological disorders. Human T-lymphotropic virus type I-associated myelopathy (HAM) is a rare progressive disease in which abnormalities are rarely observed on spinal images. We present the case of a 55-year-old woman with PLMS who was later diag-nosed with HAM. The current case indicates that HAM can be considered a possible cause of PLMS.
