O espectro clínico e laboratorial da doença de Alzheimer: Uma perspectiva neurológica

This narrative review of the literature aims to show the most recent changes related to the diagnosis of Alzheimer's disease (AD). The diagnosis remains clinical, however, there is a growing understanding that specific biomarkers in cerebrospinal fluid and molecular neuroimaging may play an important role in the etiopathogenic definition of the disease. Biomarkers may be particularly important for the diagnosis in the early stages of AD. Considering that AD is a brain pathophysiological process, the presence of AD biomarkers indicates the diagnosis of AD. Currently, the use of biomarkers is directed towards clinical research and the development of new drugs.
