NREM sleep alpha and sigma activity in Parkinson’s disease: Evidence for conflicting electrophysiological activity?

Highlights • Sleep EEG spectral patterns investigated in eight newly diagnosed, non-depressed, non-demented, drug-naïve Parkinson’s disease patients compared to nine healthy aged controls. • Concomitantly increased scalp EEG alpha and sigma activity found during non-REM sleep in Parkinson’s disease....

Description
Summary:Highlights • Sleep EEG spectral patterns investigated in eight newly diagnosed, non-depressed, non-demented, drug-naïve Parkinson’s disease patients compared to nine healthy aged controls. • Concomitantly increased scalp EEG alpha and sigma activity found during non-REM sleep in Parkinson’s disease. • These sleep microstructure changes may represent evidence for altered electrophysiological mechanisms leading to sleep–wake instability in early disease stages.
