If you live in EU you may care to participate in this survey. The more data collected in a survey of this kind the better. It is a European-only survey...the USA is not a choice...sorry.

"...a new patient survey being conducted across EPDA member countries and supported by pharmaceutical company, GlaxoSmithKline, focusing on the realities of living with Parkinson’s disease (PD) both ‘day and night’."
"The survey contains questions surrounding difficulties with daily activities such as eating and dressing, mood and possible impact on relationships plus sleep disturbances and emotional well-being. It is hoped that the results of the survey will highlight the need for better control of PD symptoms over a 24-hour period and some of the less widely addressed aspects of living with the condition."
