Rbd-399.avi

In a significant study evaluating the diagnostic accuracy of REM Sleep Behavior Disorder (RBD), the number specifically identifies a cohort of patients within a larger clinical dataset.

: The "399" figure highlights the strong correlation between RBD symptoms and long-term neurological health. RBD is often a prodromal (early) marker for synucleinopathies, including Parkinson's disease and Lewy body dementia. Core Features of REM Sleep Behavior Disorder RBD-399.avi

RBD is a parasomnia characterized by the lack of "muscle atonia" (temporary paralysis) that normally occurs during REM sleep. This leads to several distinct clinical features: In a significant study evaluating the diagnostic accuracy

To provide a feature related to , it is important to clarify that "RBD-399" appears as a specific code in neurobiological research—specifically regarding the diagnosis and progression of REM Sleep Behavior Disorder (RBD). Understanding RBD-399 in Clinical Research Core Features of REM Sleep Behavior Disorder RBD

: Research published by the American Academy of Neurology analyzed 1,130 cases with RBD diagnostic codes. Out of 499 cases identified as having secondary causes for the disorder, exactly 399 (80%) were determined to have a neurodegenerative parkinsonian disorder or dementia (NPD) diagnosis.
