Conditions

ADHD - Attention Deficit Disorder With Hyperactivity, Chronic Pain, Fibromyalgia (FM)

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

BIOLOGICALSamples

Blood and urine samples including metabolomic analyses.

OTHERQuestionnaires

Completing self-assessment questionnaires

OTHERSensitivity to mechanical pain

Assessment of sensitivity to mechanical pain (by using the Von Frey monofilament test)

Primary

MeasureTime frameDescription
Percentage of patients with fibromyalgia among patients with ADHD and no prior methylphenidate treatmentBaselineComparison 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

Secondary

MeasureTime frameDescription
Percentage of patients with fibromyalgia among patients with ADHD and a current methylphenidate treatmentBaselineComparison 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
