NCT02275884

Brief Summary

This study evaluates plasma concentrations of pharmacologically active constituents of chocolate and their effects on motor and non-motor symptoms of Parkinson's disease. Following one week of abstinence from cocoa-containing products, patients with Parkinson's disease will be randomized to receive either dark or white chocolate. After one week of chocolate consumption, patients will then cross over to white or dark chocolate, respectively, and take the corresponding chocolate product for another week. Blood samples will be taken at baseline, week 1 and week 2 to examine plasma concentrations of pharmacologically active constituents of chocolate at all three timepoints. Moreover, patients will be clinically examined for motor and non-motor symptoms at all visits.

Outcome Measures

Primary Outcomes (2)

  • Change in plasma concentrations of pharmacologically active constituents of chocolate after one week consumption of dark chocolate in comparison to baseline and to one week consumption of white chocolate

    7 days

  • Change in the severity of motor and non-motor symptoms of PD after one week consumption of dark chocolate in comparison to baseline and to one week consumption of white chocolate

    Changes in motor symptoms will be assessed with the UPDRS, changes in non-motor symptoms will be assessed with NMSS and NMSQuest.

    7 days

Secondary Outcomes (3)

  • Change in cognitive measures (MoCA, SCOPA-COG) after one week consumption of dark chocolate in comparison to baseline and to one week consumption of white chocolate

    7 days

  • Change in depressive symptoms (BDI-II) after one week consumption of dark chocolate in comparison to baseline and to one week consumption of white chocolate

    7 days

  • Change in the quality of life (PDQ-39) after one week consumption of dark chocolate in comparison to baseline and to one week consumption of white chocolate

    7 days

Study Arms (2)

Dark chocolate (85% cocoa)

ACTIVE COMPARATOR

Patients will initially receive 50 grams of dark chocolate (85% cocoa) b.i.d. for one week. Patients will then cross over to intake of 50 grams of white chocolate (0% cocoa) b.i.d. for another week.

Dietary Supplement: Dark chocolate (85% cocoa)Dietary Supplement: White chocolate (0% cocoa)

White chocolate (0% cocoa)

SHAM COMPARATOR

Patients will initially receive 50 grams of white chocolate (0% cocoa) b.i.d. for one week. Patients will then cross over to intake of 50 grams of dark chocolate (85% cocoa) b.i.d. for another week.
