Skin may be a good candidate biomarker for detecting hidden brain disorders earlier. Abnormal proteins which accumulate in the brain in neurodegenerative disorders such as Alzheimer’s Disease and Parkinson’s Disease can be found in the skin too.
Research is still at an early stage, but it has been proposed that skin tests could help diagnose brain conditions such as Alzheimer’s and Parkinson’s Disease.
