Since Alzheimer's disease (AD) is a progressive neurodegenerative brain disease, the altered cognitive symptoms in the very early stage of AD involve mild learning, memory or planning problems. Eventually, AD patients will lose their ability to carry out the simplest tasks of daily living when in the later severe stage. Currently, no medical tests are available to diagnose AD conclusively pre-mortem. The goal of our research is to confirm the preclinical cognitive markers of AD with neuropsychological approach used for AD early detection.
