The world has a rapidly ageing population. Neurodegenerative diseases (ND) are strongly linked with age, with older citizens more at risk. Therefore the prevalence of ND is increasing dramatically. The major problem with ND is its difficulty to be diagnosed early. The goal of biomarker characterization is to increase certainty that a person has or does not have underlying pathology. During last decades, many research projects where focused on research on biomarkers for ND and this research has blasted into hundreds of scientific articles. However, few studies assessed their use in real clinical practice conditions. This Frontiers Research Topic is focused in the use of biomarkers for neurodegenerative disorders in the clinical setting. Topics include the use of biomarkers in the differential diagnosis of ND, the use of biomarkers to assess the risk of conversion from preclinical conditions, the use of biomarkers to follow up of clinical conditions and studies comparing biomarkers. We challenge to publish studies not only for the more frequent and more studied ND (Alzheimer’s and Parkinson’s diseases), but also for other less known ND such as prion diseases, motor neurone diseases, Huntington’s disease, spinocerebellar ataxia |
