Abstract

Disturbances of the circadian timing system following daylight saving time (DST) may influence the symptoms of Parkinson's disease (PD). To address this question, we compared the severity of motor fluctuations and non-motor symptoms both before and after the time change. Total daily "off-time" based on diaries, excessive daytime sleepiness (Epworth Sleepiness Scale), depressive symptoms (Beck Depression Inventory), and psychosis associated with PD were assessed both before and after the DST. Eighty-three PD patients (mean age, 67±7.7years; mean disease duration, 10.4±6.4years) were included. Thirty-six patients had motor fluctuations (mean daily "off-time", 4.8±2.4h/day). There was no significant variation of the total daily "off-time" (2.5±2.6h/day versus 2.5±2.7h/day), ESS (8.3±4.8 versus 8.1±4.9), BDI (10.4±6.2 versus 10.0±6.9), or PAPD (1.4±1.6 versus 1.1±1.6) scores (P>0.05) after DST. Our results suggest that PD patients cope relatively well with DST.
