It is only recently that Alzheimer's disease has become recognized as
a major public health concern. Not only those diagnosed with Alzheimer
's disease are impacted by the disease; the emotional toll exacted on
caregivers is enormous, and the financial costs incurred by the United
States are staggering. Early diagnosis of Alzheimer's disease can pre
vent costly and inappropriate treatment and permits earlier treatment
of symptoms. There have been several recent pharmacologic advances in
the treatment of Alzheimer's disease, including the development of ace
tylcholinesterase inhibitors. For any intervention to prove successful
, however, early and accurate diagnosis and effective disease manageme
nt are crucial.
