Resting-state cortical alpha frequency in Parkinson’s disease and multiple system atrophy: associations with diagnosis, age, and symptom burden
Parkinson’s disease (PD) and multiple system atrophy (MSA) are clinically overlapping neurodegenerative disorders that present with a complex, heterogeneous burden of motor and non-motor symptoms. Resting-state EEG reveals that cortical alpha slowing is a hallmark of pathological aging, yet its specific presence an...
