New York: US doctors are developing a skin test that could detect Alzheimer’s at an earlier stage.
Currently there is no way to detect the disease in which doctors believe may begin before symptoms show in old age. There is also no cure.
Early detection would mean that intervention with drugs that assist in minimising some symptoms may be more helpful if given earlier.
The new test is based on the discovery that the disease causes a change in a common body enzyme which means it can be detected by its reaction to certain chemicals.
The US team from the Blanchette Rockefeller Neurosciences Institute in Maryland hope to bring the test to patients within five years. Doctors Tapan Khan and Daniel Alkon report their findings in the Proceedings of the National Academy of Sciences.
