New insights on Alzheimer's disease diagnostic.

One of the most common problems encountered in a world characterized by demographic ageing is Alzheimer's disease (AD) with an estimated number of 35.6 million people affected in 2010 to 65.7 million in 2030. Under recognition and delayed diagnose create problems for people diagnosed with dementia, for their families and for entirely health system. Although there have been many breakthroughs and new insights into AD etiopathogeny in the last two decades, few steps have been made toward an accurate diagnosis but all steps point into one major direction namely "personalized medicine" that could represent a future perspective for AD patients. Starting with a more accurate diagnosis not of the clinical syndrome, but of underlying molecular defects, that may eventually lead to a personalized, more effective treatment.
