As he Alzheimer's As the Parkinson they are neurodegenerative diseases that appear after the age of 50, are progressive and get worse over time; However, when treated prematurely, the quality of life of patients can be improved.
A study conducted in theCentral Hospital of the University of San Luis Potosí, in Mexico , ensures that a skin test is sufficient to detect if a person is prone to develop any of the two diseases.
The study published in the American Academy of Neurology , explains that only a skin biopsy is needed to detect if there are proteins that favor the development of Parkinson's or Alzheimer's.
"The diseases usually go unnoticed until the disease has progressed, so this skin test is very effective to detect it in time," says Ildefonso Rodríguez Leyva, one of the authors of the study.
He explains that the skin has the same origin as brain tissue, so the "abnormal proteins" (TAU) that cause the ailments are also found in the largest organ of the body.
For example, people with Parkinson and Alzheimer they register an eight times higher level of the alpha-synuclein protein than those who do not.
With a skin biopsy, doctors will identify and diagnose the diseases before they occur.
