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.
