Main objective

Scope: Therapy

To determine the correlative links between the availability of serotonergic 5-HT2A receptors and the variations in impulsivity measured in adults with Tourette's syndrome during treatment begin in the routine care.

Secondary objectives 3

  1. To determine the correlative links between the availability of serotoninergic 5-HT2A receptors and the variations of each of the other psycho-behavioural data measured in adults with Tourette's syndrome during treatment begin in the routine care
  2. To determine the correlative links between cerebral activity measured by fMRI and variations in impulsivity measured in adults with Tourette's syndrome during treatment begin in the routine care
  3. To determine the correlative links between cerebral activity measured by fMRI and the variations of each of the other psycho-behavioral data measured in adults with Tourette's syndrome during treatment begin in the routine care.

Study design 1 period

#TitleAllocationBlindingRoles blindedArms
1 Administration of a PET radiotracer
A highly selective 5-HT2A receptor ligand ([18F]-altanserin) will be injected to patients before each PET scan. The IV injection in the arm (via a cathether) will be performed in continue during a period of 2 hours in the imaging centre (CERMEP) before the acquisition. The dose will be 2,6 MBq/kg  10 % depending the prescription of the nuclear medicine. Patients will be evaluated twice, one time free of neuroleptic treatment and a second time during stable chronic treatment by neuroleptic.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Correlation coefficients between changes in the binding potential (BPND) of [18F]-altanserin measured voxel-by-voxel in the whole brain and the evolution of scores BIS11 in TD patients.

Secondary endpoints 3

  1. Correlation coefficients between changes in the binding potential (BPND) of [18F]-altanserin measured voxel-by-voxel in the whole brain and the evolution of other clinical scores and task performance of TD patients.
  2. Correlation coefficients between changes in the BOLD signal measured voxel-by-voxel in the whole brain and the evolution of scores BIS11 in TD patients.
  3. Correlation coefficients between changes in the BOLD signal measured voxel-by-voxel in the whole brain and the evolution of other clinical scores and task performance of TD patients.
