Trial summary

Patients with Parkinson's disease (PD) are known to be affected by subtle cognitive impairment early in the disease course, mostly in the executive field. Procedural motor skills, mainly controlled by the basal ganglia associative loop (in particular dorsal caudate nucleus) (Rodriguez-Oroz et al., 2009), have also… Read more about this study

About this study

Official title: Correlation of Procedural Motor Skills Impairment and 123I-FP-CIT SPECT Uptake in Patients With Early Parkinson's Disease: a Case-control Study

Patients with Parkinson's disease (PD) are known to be affected by subtle cognitive impairment early in the disease course, mostly in the executive field. Procedural motor skills, mainly controlled by the basal ganglia associative loop (in particular dorsal caudate nucleus) (Rodriguez-Oroz et al., 2009), have also been studied in patients with PD (Schnider et al., 1995; Muslimovic et al., 2007; Terpening et al., 2013). However, the correlation of dopaminergic 123I-FP-CIT SPECT imaging and cognitive impairment has not been assessed. One reason is the absence of reference values for striatal uptake until recently. Last year, the investigators established local uptake reference values for DAT imaging based on a large cohort of subjects with non-degenerative conditions (Nicastro et al., 2016) and can therefore use these values to precisely assess uptake loss in patients with PD.

With the present study, the investigators expect to enroll patients with early PD for whom a 123I-FP-CIT SPECT has been previously performed in the center. Subjects will perform a specific motor task based on mirror-drawing of star-shaped figures. This will be done by inverting the direction of horizontal/vertical computer mouse movements on the screen. Speed and error rates will be assessed for patients as well as healthy control subjects. Correlation with striatal SPECT uptake, especially caudate nucleus uptake, will be analyzed for PD patients. In addition, resting-state EEG will be performed for all subjects. General medication and dopaminergic drugs in particular, whenever used, will not be discontinued. For all subjects enrolled in the study, cognitive and neurological examination will be performed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Procedural motor performance (error and time) in PD group

    Evaluation of error rate and speed for completion of mirror-drawing of star-shaped figures

    Measured: 2 days

Secondary outcomes (2)
  1. Resting state EEG connectivity in PD and control groups

    Evaluation of resting state EEG connectivity in both groups

    Measured: 2 days

  2. Difference >20% in error rate and speed improvement in control and PD groups

    Evaluation of a >20%-difference between PD and control groups in terms of speed and error rate for the successive procedural motor task trials

    Measured: 2 days

Questions about this trial

What is this clinical trial studying?

A study testing Procedural Motor Skills with mirror-drawing of figures in people with Parkinson Disease, run by University Hospital, Geneva at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Procedural motor performance (error and time) in PD group (time frame: 2 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jul 2017.
