Until recently, Alzheimerâs disease (AD) was diagnosed clinically by excluding other conditions and pathologies, at best resulting in a diagnosis of probable AD . Compared to autopsy-confirmed diagnoses, only 68% of the dementia patients were correctly diagnosed using these clinical diagnostic criteria for AD . Moreover, a clinical diagnosis of probable AD was confined to the dementia stage of the disease, following several years of progressive cognitive deterioration and behavioral changes. The neuropathological brain lesions that consist of senile plaques and neurofibrillary tangles, start developing many years before the first symptoms of the disease appear.
