Abstract: Importance of dementia and Alzheimer’s disease (AD): On Earth, there is a “country” that we call Dementia with around 50 million inhabitants and an estimated global economic cost of US $1 trillion (Wimo et al., 2017). AD may contribute to 60–70% of cases, with other major forms of dementia being vascular dementia, dementia with Lewy bodies and a group of diseases that contribute to frontotemporal dementia. However, the boundaries between different forms of dementia are indistinct and mixed forms often co-exist, which are only confirmed after postmortem neuropathological studies (Fernandez-Vega et al., 2015).
