Skin test may be helpful to diagnose Alzheimer's disease

Researchers believe that a skin test could someday help positively diagnose someone suspected of having dementia.

Researchers in Mexico have developed the test that has ability to detect abnormal proteins related to Alzheimer's and Parkinson's disease. The group Alzheimer’s disease International informed that over 44 million people around the world get affected from Alzheimer’s and it also takes short-term memory of mostly elderly people.

The most common type of dementia is Alzheimer's disease. Other forms of progressive brain disease are also there, like vascular dementia. The movement disorder, also known as Parkinson’s disease, is another progressive neurological disease that is not easy to diagnose in its early stages.

A way to diagnose Alzheimer’s and other cognitive disorders has been developed by researchers from Mexico's University of San Luis Potosi. The researchers will make use of small piece of a patient's skin to diagnose. According to Neurologist Ildefonso Rodriguez-Leyva, who led a study, the researchers make use of skin biopsies to diagnose people with various forms of dementia.

“The skin is very closely related with the neurological system because they both have the same origin”, said Rodriguez-Leyva.

According to Rodriguez-Leyva, twenty people with diagnosis of Alzheimer’s were found to have elevated levels of a protein called tau in a 4-millimeter skin sample.
