Motor Activation in Multiple System Atrophy and Parkinson Disease: a Positron Emission Tomography (PET) Study - Full Text View

Purpose

Background: Multiple System Atrophy (MSA) is an atypical parkinsonian syndrome including cerebellar impairment and poor response to dopatherapy. The objective of the study is to assess right-hand motor activation in MSA patients before and after an acute levodopa challenge and to compare these data with those obtained in patients with Parkinson Disease (PD) and healthy volunteers (HV).

Methods: Eighteen MSA patients, eight PD patients and 10 age-matched HV will be included. rCBF measurements with H215O PET will be performed at rest and during a right hand movement. Statistical parametric mapping will be used to analyze motor versus rest in OFF and ON condition and effect of levodopa on motor activation.

Hypothesis: MSA and PD patient should recruited different motor networks.

Primary Outcome Measures:

The "movement effect" consists of comparing the images obtained during hand movement with those acquired at rest for each group (MSA, PD and Healthy subjects) using the Family Wise Error (FWE) statistical threshold in OFF and ON conditions [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Difference between motor activation of the three groups in OFF condition [ Designated as safety issue: No ]
Difference between motor activation during OFF and ON condition in each group reflecting levodopa effect on motor activation [ Designated as safety issue: No ]

Arms	Assigned Interventions
Experimental: Drug and radiation Levodopa and H215O PET	Radiation: H215O PET H215O PET investigations will be performed during two pharmacological conditions: OFF (e.g after 12 hours of usual dopaminergic treatment discontinuation) and ON (after an acute oral levodopa challenge) in all subjects. During each PET there will be two motor conditions: rest (no movement, hand and wrist lying on the joystick) and a right-hand movement, consisting of moving joystick in 4 four different directions avoiding sequence repetition performed at rest and during a right hand movement. Other Name: To measure rCBF, 300 MBq of H215O will be administered for each 80-second emission scan. Drug: Levodopa Levodopa: the dosage of levodopa challenge will be equivalent to the first morning dose increased by 100 mg of levodopa whereas the dosage will be 200 mg in healthy subjects.

Eligibility


Ages Eligible for Study:	40 Years to 75 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	Yes

Criteria

Inclusion Criteria:

MSA patients will be included if they met Gilman criteria for probable MSA. All those subjects will be distinguished between parkinsonian form (MSA-P) and cerebellar form (MSA-C). All will underwent Unified Parkinson's Disease Rating Scale UPDRS and International Cooperative Ataxia Rating Scale ICARSS. All patients will have a poor response to levodopa (<30% of the UPDRS score).
Patients with PD will be included if they suffered from idiopathic PD according to the criteria of UKPDSBB and had a positive response to levodopa (≥ 30% improvement on UPDRS part III).
All healthy subjects will have normal neurological examination and none will have a history of neurological, cardiovascular or psychiatric disturbance.
For all subjects, handedness will be determined by the Edinburg test. For all patients (MSA and PD) a MRI brain scan will be realized
