In this discussion, Dr. Gulcin Benbir, a neurology professor from Turkey specializing in sleep disorders, and Dr. Lourdes Del Rosso, a UCSF sleep physician and RLS guidelines task force member, shine a light on periodic limb movement disorder (PLMD). They reveal that 30% of patients with obstructive sleep apnea still experience significant limb movements even after treatment. The duo explores the relationship between PLMD and restless legs syndrome, iron levels' role in treatment, and whether PLMs are merely symptoms or contributors to more serious health issues.
