Alzheimer’s disease (AD) is the most common type of
dementia and is prevalent worldwide [1, 2].The risk factor of
AD is aging [3].With an increase of the elderly population as
reported by the UnitedNations [4], it is expected that the AD
population will only grow in the future. Although treatment
for AD has yet to be established, medications such as acetylcholinesterase
inhibitors can delay the progress or improve
symptoms of AD in its early stages and are readily available.
With a projected increase in the AD population and rising
awareness of early intervention measures, early detection has
become an increasingly important issue, generating demand
for screening tests with higher sensitivity.
