Fig. 1 aFrom: Salivary beta amyloid protein levels are detectable and differentiate patients with Alzheimer’s disease dementia from normal controls: preliminary findingsSalivary Aβ42 levels (pg/ml) were significantly higher in patients with Alzheimer’s disease than in normal controls. b Salivary Aβ42 levels (pg/ml) depicted by age. The values are not age dependent (F = 2.27, p-0.14)Back to article page
