1. Involvement of the monoaminergic system in pathogenesis of Alzheimer’s disease Does Aβ pathology precedes tau pathology? Andreasson et al., 2007.
1) Šimić et al., 2014.
2) Theearlyoccurrenceofbehavioral, andpsychologicalsymptomsofdementiasuggestsbrainsteminvolvement, and more specificallyoftheserotonergicnuclei. Šimić et al., 2009. 3) Plaque formation in the brain of transgenic mouse model (APPswe/PS1DE9 ) of AD causes the deterioration of sleep–wake cycle lesions of the raphe nuclei cause insomnia Roh et al., 2012.
4) exposure to inorganic mercury, bismuth and silvercan lead to AD-like pathology in noradrenergic locus coeruleus neurons spreads to neighbouring serotonergic dorsal raphe neurons locus coeruleusneurons
2. Monoamine metabolites in early diagnosis of Alzheimer’s disease • Controversialresults of the studies on CSF monoamine metabolites in AD patients
Core CSF biomarkers Aβ1-42 T-tau P-tau181 NovelCSF biomarkers P-tau231 VILIP-1 P-tau199
Noninvasivelymeasuredpotential AD biomarkers Laczo et al., 2009. Measurement od event-related potentials.
Components of event-related potentials (reaction times and P300 amplitude) differentiated two groups of MCI patients with pathological and normal levels of p-tau199 and VILIP-1.
