E.2.1 | Main objective of the trial |
To describe the critical role of the locus coeruleus-noradrenaline system in the pathophysiology of Parkinson’s tremor.

Om de rol van het locus coeruleus-noradrenerge systeem in de pathofysiologie van de ziekte van Parkinson te beschrijven.
|
|
E.2.2 | Secondary objectives of the trial |
- To test the ability of propranolol to inhibit stress-induced resting tremor. - To identify patient-specific noradrenergic markers (functional and structural) that predict how sensitive his/her tremor is to acute psychological stress and a targeted pharmacological intervention (propranolol). |
- Om te testen in hoeverre propranolol stress-geinduceerde Parkinson tremor vermindert. - Om patient-specifieke noradrenerge markers (functioneel en structureel) te identificeren die voorspellen hoe gevoelig zijn/haar tremor is voor acute psychische stress en een gerichte farmacologische interventie (propranolol). |
