Noninvasive biomarker for Parkinson's disease possibly found in EEG data

Specific angles and sharpness of brain waves seen in unfiltered raw data from scalp electroencephalograms have been tied to Parkinson’s disease. The findings, researchers say, may provide easily detectable electrophysiological biomarkers to aid the diagnosis and fine-tune therapeutic treatments for the disease and other motor disorders.
