Simple Skin Test May Spot Alzheimer's Early

A simple skin test that enables doctors to diagnose the early signs of Alzheimer's disease could be available within five years, researchers say.

The test could allow doctors to intervene early on and prevent major brain damage, they say.

Researchers at the Blanchette Rockefeller Neurosciences Institute in Rockville, Maryland, US, have identified chemical changes that distinguish early Alzheimer's from other neurodegenerative disorders.
