RESUMEN

Previous studies indicate effects of oral contraceptive (OC) use on spatial and verbal cognition. However, a better understanding of the OC effects is still needed, including the differential effects of androgenic or anti-androgenic OC use and whether the possible impact persists beyond the OC use. We aim to investigate the associations of OC use duration with spatial and verbal cognition, differentiating between androgenic and anti-androgenic OC. Using functional magnetic resonance imaging (MRI), we scanned a group of 94 past and current OC-users in a single session. We grouped current OC users (N=53) and past OC users with a natural cycle (N=41) into androgenic and anti-androgenic user. Effects of OC use duration were observed for current use and after discontinuation. Duration of OC use was reflected only in verbal fluency performance but not navigation: The longer the current OC use, the less words were produced in the verbal fluency task. During navigation, deactivation in the caudate and postcentral gyrus was duration-dependent in current androgenic OC users. Only during the verbal fluency task, duration of previous OC use affects several brain parameters, including activation of the left putamen and connectivity between right-hemispheric language areas (i.e., right inferior frontal gyrus and right angular gyrus). The results regarding performance and brain activation point towards stronger organizational effects of OCs on verbal rather than spatial processing. Irrespective of the task, a duration-dependent connectivity between the hippocampus and various occipital areas was observed. This could suggest a shift in strategy or processing style with long-term contraceptive use during navigation/verbal fluency. The current findings suggest a key role of the progestogenic component of OCs in both tasks. The influence of OC use on verbal fluency remains even after discontinuation which further points out the importance of future studies on OC effects and their reversibility.

RESUMEN

BACKGROUND: 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. OBJECTIVE: 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. STUDY DESIGN: 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. RESULTS: After treatment, participants in both groups demonstrated marked improvement in incontinence episodes (P<.001). Bladder-filling task functional magnetic resonance imaging data from the combined groups (n=64, 30 hypnotherapy, 34 pharmacotherapy) demonstrated decreased activation of the left temporoparietal junction, a component of the ventral attentional network (P<.01) compared with baseline. Resting functional connectivity differed only with the bladder partially filled (n=54). Compared with pharmacotherapy, hypnotherapy participants manifested increased functional connectivity between the anterior cingulate cortex and the left dorsolateral prefrontal cortex, a component of the dorsal attentional network (P<.001). CONCLUSION: Successful treatment of urgency urinary incontinence with both pharmacotherapy and hypnotherapy was associated with decreased activation of the ventral (bottom-up) attentional network during bladder filling. This may be attributable to decreased afferent stimuli arising from the bladder in the pharmacotherapy group. In contrast, decreased ventral attentional network activation associated with hypnotherapy may be mediated by the counterbalancing effects of the dorsal (top-down) attentional network.
