Restless legs syndrome andperiodic leg movement syndrome have been associated with iron deficiency, kidneydisease, diabetes, and neurological, autoimmune, cardiovascular and respiratorydisorders. Rapid eye movement behaviour disorder has been described as an earlymanifestation of serious central nervous system diseases; thus, close neurologicalmonitoring of patients referring with this complaint is indicated.
SummaryIdentification and management of any sleep disorder in medical patients is important foroptimizing the course and prognosis. Of equal importance is the search for undetectedmedical disorder in patients presenting with sleep disorders.
