Troina, November 14-15, 2025

A major international meeting on the diagnostic standards for Periodic Limb Movements in Sleep (PLMS) has just concluded at the IRCCS Oasi Maria SS. Institute in Troina, Italy. PLMS is among the most widely studied sleep-related movement disorders due to its significant impact on sleep quality and daily functioning.

From November 13 to 16, 25 leading experts from around the world worked together to refine the scientific criteria that underpin the diagnosis of this condition, which affects a considerable portion of the general population.

The event, organized by Drs. Raffaele Ferri and Stephany Fulda, and endorsed by the World Sleep Society (WSS), the International Restless Legs Syndrome Study Group (IRLSSG), and the European RLS Study Group (EURLSSG), marks the third time Troina has hosted such a high-level gathering, following previous milestone meetings in 2005 and 2015.

The outcomes of this collaborative effort will now be consolidated into a consensus document to be published in Sleep Medicine. These updated standards will guide more accurate diagnosis worldwide and foster the development of future research to better clarify the neurophysiological mechanisms and health consequences of PLMS.
