People with Parkinson’s disease who are experiencing cognitive decline may show weaker low-frequency brain waves on an electroencephalogram (EEG), a recording of the brain’s electrical activity, according to a recent study.
Brain waves recorded at the front part of the brain were linked to measures of cognitive decline and executive function impairment.
“Our work provides insight into fundamental mechanisms of [Parkinson’s disease]-related cognitive dysfunction and could lead to novel targeted therapies and neurophysiological biomarkers for cognitive symptoms of [Parkinson’s disease],” researchers wrote.
