REM sleep behavior disorder in sleep-disordered patients with versus without Parkinson's disease: is there a need for polysomnography?
Eisensehr I, v Lindeiner H, Jäger M, Noachtar S.. Journal of the neurological sciences, 2001-05-01
Topic: Risk, prevention and care in population studies
We reviewed the polysomnograms (PSGs) of 292 consecutive patients with sleep disorders (Parkinson's disease (PD), n=19, other sleep disorders, n=273) to investigate the sensitivity and specificity of the clinical diagnosis of rapid eye movement behavior disorder (RBD) compared with polysomnographic diagnosis. Patients with dementia, multiple system atrophy, or any other neurodegenerative disease were excluded. RBD was diagnosed clinically if the minimal criteria, according to the guidelines given in the International Sleep Disorders Classification, were fulfilled. The following PSG criteria were required for diagnosis of RBD: REM sleep without muscle atonia seen in PSG associated with motor behavior visible in the PSG-synchronized videotape. Nine of nineteen PD patients (47%) had RBD. RBD occurred in only four patients without PD (1.8%). The sensitivity of specialized interviews for identifying RBD clinically was good in non-PD patients (sensitivity: 100%, specificity: 99.6%). However, the sensitivity was poor (33%) with a specificity of 90%, in patients with PD. We conclude that the diagnosis of RBD in patients with PD requires PSG, whereas interviews are sufficient for diagnosing RBD in non-PD patients.

Key findings
- We reviewed the polysomnograms (PSGs) of 292 consecutive patients with sleep disorders (Parkinson's disease (PD), n=19, other sleep disorders, n=273) to investigate the sensitivity and specificity of the clinical diagnosis of rapid eye movement behavior disorder (RBD) compared with polysomnographic diagnosis.
- The following PSG criteria were required for diagnosis of RBD: REM sleep without muscle atonia seen in PSG associated with motor behavior visible in the PSG-synchronized videotape.
- We conclude that the diagnosis of RBD in patients with PD requires PSG, whereas interviews are sufficient for diagnosing RBD in non-PD patients.

How this study scored 47/100
Published in a peer-reviewed journal. Scored zero for study design 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.
