Obstructive sleep apnea decreases central nervous system-derived proteins in the cerebrospinal fluid

Topic: Plasma and spinal-fluid biomarkers
We hypothesized that one mechanism underlying the association between obstructive sleep apnea (OSA) and Alzheimer's disease is OSA leading to decreased slow wave activity (SWA), increased synaptic activity, decreased glymphatic clearance, and increased amyloid-β. Polysomnography and lumbar puncture were performed in OSA and control groups. SWA negatively correlated with cerebrospinal fluid (CSF) amyloid-β-40 among controls and was decreased in the OSA group. Unexpectedly, amyloid-β-40 was decreased in the OSA group. Other neuronally derived proteins, but not total protein, were also decreased in the OSA group, suggesting that OSA may affect the interaction between interstitial and cerebrospinal fluid. Ann Neurol 2016;80:154-159.
Key findings
- Other neuronally derived proteins, but not total protein, were also decreased in the OSA group, suggesting that OSA may affect the interaction between interstitial and cerebrospinal fluid.

How this study scored 41/100
Published in a leading specialty journal. Scored zero for study design, sample size, effect reported, studied in people 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, multi-centre collaboration and free to read, so those were left out: it earned 23 of the 56 points we could judge it on, which is 41 out of 100.
