- Change in the Frequency of REM Sleep Behavior Disorders (RBD) From Baseline to the End of the Treatment Period (28 Days) Based on a Clinical Evaluator. [ Time Frame: 28 days ]The number of RBD (sum of simple/major and complex RBD events) per 10 minutes, based on video/audio assessment conducted at a sleep laboratory. Simple/major behaviors are jerks with higher movement amplitude, or intensity (e.g., whole body jerks, single limb jerk); Complex behaviors are Movements showing complexity of action and involving more muscle groups simultaneously or violent movements, and can be seen as the enactment of dream contents.
