ADHD - Attention Deficit Disorder With Hyperactivity, Chronic Pain, Fibromyalgia (FM)
Conditions
Brief summary
The overall objective of the research project presented here is to assess the prevalence of fibromyalgia in patients being treated for ADHD, the prevalence of ADHD in patients being treated for fibromyalgia, and the neurobiological correlates of ADHD-fibromyalgia comorbidity.
Interventions
Blood and urine samples including metabolomic analyses.
Completing self-assessment questionnaires
Assessment of sensitivity to mechanical pain (by using the Von Frey monofilament test)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of patients with fibromyalgia among patients with ADHD and no prior methylphenidate treatment | Baseline | Comparison of the observed prevalence of fibromyalgia (as assessed by the ACR diagnostic criteria) among patients with ADHD (as assessed by the DIVA-5 diagnostic interview) and no prior methylphenidate treatment versus the theoretical prevalence of fibromyalgia in the overall French population |

|---|---|---|
| Percentage of patients with fibromyalgia among patients with ADHD and a current methylphenidate treatment | Baseline | Comparison of the observed prevalence of fibromyalgia (as assessed by the ACR diagnostic criteria) among patients with ADHD (as assessed by the DIVA-5 diagnostic interview) and a current methylphenidate treatment versus the theoretical prevalence of fibromyalgia in the French overall population |
