Alzheimer's disease (AD) is a progressiveneurodegenerative disorder that usually starts with memory loss and other cognitive deficits. At the time of clinical diagnosis,
most patients are already in the moderate to severe stages
of AD. Although there is no specific consensus definition
of moderate to severe AD [1] , patients with Mini-Mental
State Exam (MMSE) scores between 10 and 20 are usually
considered as having moderate AD and in a recent paper[2] MMSE scores were shown to be a useful surrogate
for the staging of dementia.
