Table 4.
Mean values (±SE) of the clinical (i.e., Geriatric Depression Scale, Clinical Dementia Rating, and Hachinski Ischemic Score) genetic (i.e., Apolipoprotein E genotyping, APOE), and cerebrospinal fluid (i.e., beta amyloid 1-42, Aβ 42; protein tau, t-tau; and phosphorylated form of protein tau, p-tau) data as the results of their statistical comparisons (p < 0.05 corrected) in the groups of noADMCI-noEEA (N = 19) and noADMCI-EEA (N = 13) patients.
| noADMCI-noEEA | noADMCI-EEA | Statistical analyses | |
|---|---|---|---|
| Clinical, genetic (APOE) and cerebrospinal fluid markers in noADMCI-noEEA and noADMCI-EEA | |||
| CLINICAL MARKERS | |||
| Geriatric depression scale (GDS) | 2.3 ± 0.5 | 2.3 ± 0.6 | T-test: p = 0.9 |
| Clinical dementia rating (CDR) | 0.5 ± 0.0 | 0.5 ± 0.0 | T-test: p = 1.0 |
| Hachinski ischemic score (HIS) | 1.2 ± 0.3 | 1.2 ± 0.2 | T-test: p = 0.9 |
| GENETIC MARKER | |||
| APOE4 (%) | 10.5% | 7.7% | Fisher test: p = 0.9 |
| CEREBROSPINAL FLUID MARKERS (pg/mL) | |||
| Aβ42 | 1,000 ± 44 | 1,087 ± 73 | T-test: p = 0.25 |
| p-tau | 43 ± 2 | 51 ± 5 | T-test: p = 0.15 |
| t-tau | 276 ± 29 | 343 ± 48 | T-test: p = 0.25 |
| Aβ42/p-tau | 24 ± 1 | 23 ± 2 | T-test: p = 0.6 |
All ADMCI patients had all values of those markers available. In line with the inclusion criteria, all noADMCI patients had CDR score of 0.5, GDS score ≤ 5, HIS score ≤ 4, and Aβ 42 level in the cerebrospinal fluid (CSF) > 550 pg/mL.
noADMCI-noEEA, patients with mild cognitive impairment not due to Alzheimer's disease and without epileptiform EEG activity; noADMCI-EEA, patients with mild cognitive impairment not due to Alzheimer's disease and epileptiform EEG activity. No significant difference was observed between the two noADMCI groups even when a marginal threshold of p < 0.05 uncorrected was used.
