Topic: Brain imaging, connectivity and assessment
Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia defined by intermittent loss of electromyographic atonia during REM sleep with emergence of complex and vigorous behaviors. Punching, kicking, and leaping from bed during attempted dream enactment caused repeated injury in nine of our first ten adult patients. Mean age at onset was 62 years; nine of the patients were male. All patients underwent standard polysomnographic studies with videotaping of behaviors and extensive neurologic and psychiatric evaluations. The RBD was unrelated to psychopathologic conditions but in five cases was closely linked with major neuropathologic disorders: dementia (two), olivopontocerebellar degeneration, subarachnoid hemorrhage, and the Guillain-Barré syndrome. Other common polysomnographic abnormalities were high REM density, increased stage 3/4 (slow-wave) sleep, and both periodic and aperiodic limb twitching in non-REM sleep. Eight patients had dream changes involving motor overactivity and violent confrontations of dream characters. Clonazepam induced rapid and sustained improvement of dream and sleep behavior problems in seven patients, as did desipramine hydrochloride in one patient.

How this study scored 47/100
Published in a top-tier journal. Scored zero for study design, sample size, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 27 of the 58 points we could judge it on, which is 47 out of 100.
