A study finds that clonazepam may not be the best available treatment for REM sleep behavior disorder (RBD), reports Neurology Advisor.

Although regarded as the first-line treatment for RBD due to its ability to reduce injurious behaviors, there is a lack of quantitative measures evaluating treatment response for both dream-related and behavioral symptoms.

To better delineate treatment response, researchers from The Chinese University of Hong Kong, The University of Hong Kong, and the Sleep Medicine Center at West China Hospital conducted a prospective study to examine characteristic changes in the clinical and polysomnographic features of RBD in patients treated with clonazepam.
