Kuvaus
Inclusion Criteria:
- Patients with PD defined according to UKPDSBB criteria;
- Men and women aged between 40 and 80 years;
- Patients with troublesome rest tremor assessed by the CGI-S scale ≥ 3 and persistent despite the initiation of ≥ two anti-parkinsonian treatments (levodopa, dopaminergic agonist, anticholinergic), which defines drug-resistant parkinsonian tremor;

Exclusion Criteria:
- Patients with tremors related to a pathology other than PD;
- Patients with atypical parkinsonian syndrome;

- Patients with hypersensitivity to the active substance or to one of the excipients (human albumin, lactulose);
- patients with atrophy of the target muscle
- patients with a urinary tract infection at the time of treatment if the patient suffers from urinary incontinence due to neurological detrusor overactivity

Kokeellinen: Botulinum toxin followed by placebo arm
In this cross-over study, the patient will be his or her own control.
The patient will receive both treatments at 6 months apart: DYSPORT followed by the placebo (the order of injections has been randomly assigned).
|
Both treatments, first DYSPORT 500UI for 6 months then placebo, also for 6 months, will be administered intramuscularly using the same schedule and procedures thus allowing the blind to be maintained.
The two injections will be carried at 6 months apart: the drug will be injected intramuscularly, into the muscles identified as responsible for the tremor, by an investigator specialized in carrying out injections.
The doses injected will depend on the severity of the tremor and the number of muscles injected, which is conditioned by the tremor phenotype.
