Mind-body (hypnotherapy) treatment of women with urgency urinary incontinence: changes in brain attentional networks

Prior study of patients with urgency urinary incontinence by functional magnetic resonance imaging showed altered function in areas of the brain associated with interoception and salience and with attention. Our randomized controlled trial of hypnotherapy for urgency urinary incontinence demonstrated marked improvement in urgency urinary incontinence symptoms at 2 months. A subsample of these women with urgency urinary incontinence underwent functional magnetic resonance imaging before and after treatment. This study aimed to determine if hypnotherapy treatment of urgency urinary incontinence compared with pharmacotherapy was associated with altered brain activation or resting connectivity on functional magnetic resonance imaging. A subsample of women participating in a randomized controlled trial comparing hypnotherapy vs pharmacotherapy for treatment of urgency urinary incontinence was evaluated with functional magnetic resonance imaging. Scans were obtained pretreatment and 8 to 12 weeks after treatment initiation. Brain activation during bladder filling and resting functional connectivity with an empty and partially filled bladder were assessed. Brain regions of interest were derived from those previously showing differences between healthy controls and participants with untreated urgency urinary incontinence in our prior work and included regions in the interoceptive and salience, ventral attentional, and dorsal attentional networks. After treatment, participants in both groups demonstrated marked improvement in incontinence episodes (P
