Patient preferences for prognostic counseling in idiopathic/isolated REM sleep behavior disorder

Abstract

AbstractBackgroundTo examine patient preferences regarding prognostic counseling for idiopathic/isolated REM sleep behavior disorder (iRBD). Idiopathic/isolated REM sleep behavior disorder (iRBD) carries an approximate 73‐91% long term risk for phenoconversion to dementia with Lewy bodies (DLB) and Parkinson disease (PD). Previous research has shown that most providers counsel their patients concerning this risk, yet patients’ values and preferences regarding counseling are unknown.Methods122 participants with iRBD in the Mayo Clinic iRBD Patient Registry enrolled. Participants were sent a survey concerning prognostic counseling and their experience in being diagnosed with iRBD.ResultsOf 81 respondents (67.2% response rate), 74% were men with an average age of 65.7 ± 9.7 years. Responses indicated a strong preference toward receiving prognostic information; 92.5% felt knowledge concerning neurodegenerative disease risk was important, while 87.6% felt prognostic discussion was important to maintain trust in their physician. Additionally, 95.7% indicated they desired more information, while only 4.3% would have desired less information regarding prognostic risk following iRBD diagnosis. Most respondents agreed strongly that prognostic information was important for discussions with their family and friends and future life planning, and expressed interest in learning more about future neuroprotective therapies and symptomatic treatments for parkinsonism and dementia.ConclusionsiRBD patients indicated a strong preference for disclosure of neurodegenerative prognostic risk information, preferred more rather than less information, and felt prognostic information was important for family discussions and life planning. This data informs prognostic counseling practices regarding iRBD and other neurodegenerative diseases.
