A new study published in Frontiers in Aging Neuroscience identifies formic acid as a potential biomarker for early-stage Alzheimer’s disease. Obtained from urine, the biomarker could offer an inexpensive and efficient diagnostic tool for the neurodegenerative condition. Diagnosing Alzheimer’s disease A diagnosis of Alzheimer’s disease requires a series of clinical assessments, such as interviews, cognitive and neuropsychological tests, which can prove expensive and unsuitable for large-scale routine screening. Many patients are diagnosed later in life when the disease has progressed beyond the reach of effective treatment. “Alzheimer’s disease is a continuous and concealed chronic disease, meaning that it can develop and last for many years before obvious cognitive impairment emerges,” say the authors of a new study exploring whether a simple urine test could offer a solution. “The early stages of the disease occur before the irreversible dementia stage, and this is the gol...
