Neuroimaging Effects of Cognitive Behavioral Therapy in Fibromyalgia

Brigham and Women's Hospital148 enrolled

Overview

This study design has two components: 1) a cross sectional assessment of brain connectivity and response to pain in healthy controls and demographically matched fibromyalgia patients, and 2) a longitudinal assessment of the same outcomes in fibromyalgia patients randomized to either CBT (Cognitive Behavioral Therapy) or a Disease Education condition. The investigators will evaluate a group of fibromyalgia patients who will receive CBT treatment once a week for 8 weeks, for a total of 8 treatments. Baseline data from these patients will be compared to results from pain-free controls and a group of education program controls. Participants will undergo experimental pain assessments as well as brain neuroimaging.

Investigators propose to use fMRI (functional Magnetic Resonance Imaging) to study CNS pain processing during the anticipation and experience of acute pain in individuals with FM and healthy controls. Investigators will recruit patients who are diagnosed with FM as well as healthy controls. After the baseline visit, FM participants will be randomly assigned into the CBT or control condition (Education). Overall, FM Participants will attend 8 treatment visits, and 6 assessment visits (two at baseline, one at mid-treatment, two at the end of treatment, and one at 6 months post-treatment). These assessment visits include a total of 3 fMRI sessions (at baseline, mid-treatment, and end of treatment). Healthy Controls will undergo the same baseline procedures as the FM subjects but will not attend any of the treatment or follow up assessment visits. Findings from this research will provide important information about catastrophizing's CNS (Central Nervous System) correlates.

Routine use of substances of abuse 5. Certain condition that interfere with Quantitative Sensory Testing (QST) and/or fMRI procedures (e.g., Peripheral neuropathy, implanted ferrous metal, claustrophobia etc) or/and any impairment, activity or situation that could prevent satisfactory completion of the study protocol Inclusion Criteria for Healthy Control Participants 1. Aged 18-65 2. Female 3. Right-handed 4. Able to provide written consent Exclusion criteria for Healthy Control Participants: 1. Any acute or chronic pain condition (e.g., FM, arthritis) 2. Current use of stimulant medications 3. Routine use of substances of abuse 4.

Outcomes

Primary Outcomes

Clinical outcome: Brief Pain Inventory (BPI)

Pain-related interference and pain severity

Time frame: Post-treatment, with long-term exploratory outcomes at 6 Months Post-treatment

Neurobiological Outcome: Pain Neurocircuitry (fMRI)

Bold responses will be assessed with fMRI (3T)

Time frame: Post-treatment

Secondary Outcomes

Catastrophizing (PCS)

Catatrophizing will be assessed with the Pain Catastrophizing Scale (PCS).Investigators hypothesize that early-treatment changes in catastrophizing will produce adaptive brain changes at post-treatment

Time frame: 4 weeks (mid-treatment), as well as Post-treatment
