Parkinson’s Brain-Heart Coupling Signals MMSE and Freezing of Gait
A 2026 EEG-ECG preprint reported that beta efficiency-sympathetic coupling differed across healthy young adults, healthy older adults, and Parkinson’s disease patients, p = 0.0032, while gamma efficiency-sympathetic coupling differed at p = 0.0003.1 The main claim is that motor, cognitive, and autonomic physiology may be coupled tightly enough to deserve biomarker-level study.
