How do Parkinson's disease patients manage Ramadan fasting? An observational study

Twenty-four Parkinson's disease (PD) patients who had planned to fast during the 2016 Ramadan were included in this observational study. Twenty patients fasted during the whole Ramadan. Six were able to abstain from drug intakes from dawn to dusk; the others needed 1 or 2 intakes of L-DOPA during the day. There were no serious side effects reported during the Ramadan period. Compared to before Ramadan, there were no significant changes after the fasting period in quality of life (PDQ 39), non-motor symptom scale or clinical impression of severity index scores.
