In this episode of Talking Sleep, host Dr. Seema Khosla welcomes Dr. Luca Baldelli, a neurologist from the University of Bologna and Treasurer-Elect of the International REM Sleep Behavior Disorder Study Group, to discuss breakthrough research on predicting which RBD patients will develop neurodegenerative diseases.

Building on the AASM's updated RBD guidelines, Dr. Baldelli presents compelling evidence for using simple autonomic reflex testing to identify patients at highest risk for phenoconversion to conditions like Parkinson's disease and dementia with Lewy bodies. His research demonstrates that objective autonomic testing, particularly orthostatic assessments, can reveal early neurogenic orthostatic hypotension that precedes overt neurodegeneration by years.

The conversation explores practical clinical applications: How can sleep medicine practitioners implement these screening protocols? What constitutes abnormal autonomic function in RBD patients? How do we interpret changes over time, and when should patients be referred for neurological evaluation? Dr. Baldelli shares his longitudinal monitoring framework that could transform how we counsel RBD patients about their future risk.

This episode addresses critical questions about biomarker development in prodromal neurodegeneration, the timeline of autonomic changes, and evidence-based approaches to patient discussions about prognosis. Dr. Baldelli also discusses current research initiatives and potential therapeutic interventions for high-risk patients.

Whether you're a sleep medicine physician, neurologist, or researcher interested in neurodegenerative diseases, this episode provides essential insights into improving early detection and patient care in RBD.

Join us for this informative discussion that bridges sleep medicine and neurology to enhance clinical decision-making and patient outcomes.
