  Purpose

About 46% of patients suffering from Parkinson's disease present pain disorders. Parkinson disease is characterized by loss of dopaminergic neurons. The aim of this study is to assess the relationship between the loss of dopaminergic neurons and the existence of pain in Parkinson's disease. Using single photon emission computerized tomography (SPECT) imaging (123I FP-CIT, which binds dopamine transporter) and the determination of subjective pain threshold, the investigators will establish correlations between dopaminergic degeneration and pain perception.

Primary Outcome Measures:
  • Single photon emission computerized tomography (SPECT) will be used to evaluate binding of 123I FP-CIT to dopamine transporters. This exam will allow calculation of the ratio of specific to non specific binding of 123I FP-CIT to dopamine transporters. [ Time Frame: Image acquisition (SPECT) will be performed after three hours post-injection of 123I FP-CIT. ] [ Designated as safety issue: No ]
  • Pain perception will be evaluated by the determination of subjective pain thresholds (thermal pain thresholds, thermotest). A thermode will be used to determine the heat and cold pain thresholds. [ Time Frame: Image acquisition (SPECT) will be performed after three hours post-injection of 123I FP-CIT. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Severity of Parkinson's disease will be evaluated with the Unified Parkinson's disease Rating Scale (UPDRS) and the Hoehn and Yahr scale [ Time Frame: Evaluation will be done within three hours before image acquisition (SPECT). ] [ Designated as safety issue: No ]
  • Short French version of McGill pain questionnaire (MPQ). [ Time Frame: Evaluation will be done within three hours before image acquisition (SPECT). ] [ Designated as safety issue: No ]
  • Pain intensity will be assessed using a 10 cm visual analogue scale (VAS) (0 = no pain; 10 = worst possible pain). [ Time Frame: Evaluation will be done within three hours before image acquisition (SPECT). ] [ Designated as safety issue: No ]
  • DN4 scale [ Time Frame: Evaluation will be done within three hours before image acquisition (SPECT). ] [ Designated as safety issue: No ]
  • Brief Inventory Pain [ Time Frame: Evaluation will be done within three hours before image acquisition (SPECT). ] [ Designated as safety issue: No ]
  • Hospital Anxiety and Depression (HAD) scale [ Time Frame: Evaluation will be done within three hours before image acquisition (SPECT). ] [ Designated as safety issue: No ]

Detailed Description:

Parkinson's disease is a frequent neurodegenerative disease leading to motor handicap, cognitive and pain disorders. These pain disorders could be correlated to dopaminergic loss.

The clinical trial will be conducted in a single center (Neurology Department, Purpan Hospital, Toulouse, France). The study is classified as a physiopathology one. Twenty patients with Parkinson's disease, presenting pain disorders or not, will be selected. This clinical trial will last one year. All the exams, including image acquisition will be done the same day. These will take about 6 hours for each patient.

Expected results: Binding of 123I FP-CIT to dopamine transporters should negatively correlate with pain intensity and also with thermal pain thresholds in patients suffering from Parkinson's disease.

Ages Eligible for Study:   30 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients with clinically established Parkinson's disease according to the UKPDSBB (UK Parkinson's Disease Society Brain Bank) (Gibb et Less, 1998; Hugues et al, 1992).
