LONDON: A simple skin test can now help detect Alzheimer’s and Parkinson’s disease.
Scientists have confirmed that skin biopsies can be used to detect elevated levels of abnormal proteins found in the two diseases.
“Until now pathological confirmation was not possible without a brain biopsy so these diseases often go unrecognized until after the disease has progressed,” said study author Ildefonso RodriguezLeyva from the University of San Luis Potosi in Mexico.
“We hypothesized that since skin has the same origin as brain tissue while in the embryo they might also show the same abnormal proteins.This new test offers a potential biomarker that may allow doctors to identify and diagnose these diseases earlier on,” Rodriguez-Leyva added. Article continues
