BackgroundPolysomnography (PSG) data are rare in patients who have early stage idiopathic Parkinson's disease (IPD).MethodsThirty-three patients who had IPD with a disease duration ≤ 3 years and 37 age-matched controls were recruited. PSG analysis was performed on current medication.ResultsPatients with IPD had a reduced mean percentage of muscle atonia during rapid eye movement (REM) sleep (80% vs 93%; P ConclusionsThe results confirmed a reduction in muscle atonia during REM sleep as a characteristic finding in early IPD. However, there were no further disease-inherent or medication-induced changes in sleep architecture. Although sleep disturbances are considered to be an integral part of IPD, PSG cannot yet identify them objectively at an early stage.
