REM Sleep Behavior Disorder as a Pathway to Dementia: If, When, How, What, and Why Should Physicians Disclose the Diagnosis and Risk for Dementia.

We provide an approach to risk disclosure for patients with iRBD. Patients should be asked if they want to know about future risks. If so, disclosure should be patient centered, focusing on what might happen. Discussion should occur early to give patients time to prepare for the future and consider participating in research.
