The possibility of a new treatment for Parkinson's disease has emerged, according to U.S. researchers claiming a key finding.

They said they recently discovered a glitch in cell function that can lead to the disease. In healthy cells, damaged proteins are digested and recycled in a process called autophagy. Researchers "have found in Parkinson's there are problems in removing abnormal proteins," according to Ana Maria Cuervo, cell biologist at the Albert Einstein College of Medicine of Yeshiva University,

Cuervo and her team are hopeful that new drugs to aid in the process of cleaning up abnormal proteins in cells will be available in five years time, though they say these drugs will not be a cure for the disease.
