E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Parkinson's disease, in particular the symptom Freezing of Gait |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate whether impairments of shifting between response sets underlie motor freezing in PD an to investigate the efficacy and the neural mechanism by which methylphenidate improves gait and cognition in Parkinson's disease patients with Freezing of Gait. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Parkinson's disease according to the criteria of the UK brain bank criteria. |
|
E.4 | Principal exclusion criteria |
- Presence of neurological central nervous system disorders other than idiopathic Parkinson's disease - Surgical treatment for idiopathic Parkinson's disease, such as deep brain stimulation - Dementia (i.e. a score below the cut-off of the Mattis Dementia Rating Scale) - Other significant co-morbidity - Contraindications to MRI scanning: * metal objects in or near the body, such as a pacemaker, insuline pump, prothesis and/or metal splinters in eye. * tattoos and/or piercings * claustrophobia - Controindications to the use of methylphenidate: * cardiovascular disease, including moderate to severe hypertension * structural cardiac abnormalities * cardiomyopathy * advanced arteriosclerosis * hyperexcitability * renal impairment * porphyria * bipolar disorder * unstable personality * anxiety disorder * history of suicide attempts * gilles de la tourette syndrome * thyriod disease * glaucoma * pregnancy * use of MAO-inhibitors * use of vasopressors |

E.5 End points |
E.5.1 | Primary end point(s) |
First primary outcome: performance of Parkinson's disease patients with Freezing of Gait on behavioral tasks compared to Parkinson's disease patients without Freezing of Gait. Second primary outcome: cerebral activation patterns during shifting between response sets in Parkinson's disease patients with Freezing of Gait relative to Parkinson's disease patients without Freezing of Gait. Third primary outcome: change of performance on response set shifting task after administration of methylphenidate in PD patients with Freezing of Gait. Fourth primary outcome: cerebral activation change after administration of methylphenidate in PD patients with Freezing of Gait. |
