The week from April 9th to 13th 2018 was the beginning of the i-PROGNOSIS study “Eating behavior among early and advanced patients with Parkinson’s disease”, aiming at identifying and quantifying meal-related behavioural differences (such as total food consumption and meal duration) among early and advanced Parkinson’s patients and healthy controls.

It is the beginning of a novel and productive international collaboration started with personnel from Karolinska Institute (Sweden), coming from the IMPACT group; Department of Biosciences and Nutrition to the Department of Neurology, Technical University Dresden (Germany).

During the week, a team of scientists from the two institutions recorded the patterns of eating in more than 10 Parkinson patients, using both video and a newly developed, smartwatch-based e-health toolkit (provided by the Multimedia Understanding Group of Aristoteles University, Thessaloniki, Greece). The study is ongoing, with the meals of more than 50 additional volunteers (controls and patients) being recorded in the following months, while the participants will also receive smartwatches for additional real-life monitoring of their eating behaviours in their home environment.  All participants will also undergo a medical evaluation with standardised assessments of factors possibly influencing eating behaviour, like the smell and taste function, motor functions of swallowing, as well as dietary habits and the evaluation of the personal wellbeing.

The analysis of these recordings – smartwatch, meal pictures and video based – together with the medical evaluation will help in fully describing participants eating characteristic as patients with Parkinson’s disease at different stages of the disease development and further in contrast to healthy volunteers. In parallel, the developed monitoring technologies will be included in the upcoming i-PROGNOSIS SData collection.
