Summary of total element concentrations in CSF and serum samples (mean ± SD), ratio of element concentrations. Q(CSF/serum) and comparison with Q(CSF/serum) values from [37]. Qctrl = ratio from control samples, QAD = ratio from Alzheimer’s disease samples.

| Serum (mean ± SD) | 1.35 ± 0.3 | 1220 ± 293 | 1380 ± 560 | 704 ± 159 |
| Q (CSF/Serum) (this paper) | 0.37 | 0.016 | 0.012 | 0.026 |
