Figure 1. Slow wave activity and cerebrospinal fluid Amyloid-β-40.

Figure 1

Slow wave activity, as measured by average delta power during non-rapid eye movement sleep, is negatively correlated with Aβ40 levels in the cerebrospinal fluid the following morning, in the Control group (n=29, Spearman’s r=−0.368, p=0.049). Values from the OSA group (n=10) do not have a significant correlation (Spearman’s r=0.152, p=0.676) and do not follow the same trend as the Control group. Aβ40 = amyloid-β-40. OSA = Obstructive sleep apnea.
