Coping with Childbirth: Brain Structural Associations of Personal Growth Initiative.

ABSTRACT: Major life events require psychological adaptations and can be accompanied by brain structural and functional changes. The goal of the current study was to investigate the association of personal growth initiative (PGI) as a form of proactive coping strategy before childbirth, with gray matter volume after delivery. Childbirth is one of the few predictable major life events, which, while being one of the most positive experiences for many, is also accompanied by multidimensional stress for the mother. Previous research has shown that high stress is associated with reductions in gray matter volume in limbic cortices as well as the prefrontal cortex (PFC). We hypothesized that PGI before childbirth is positively related to gray matter volume after delivery, especially in the ventromedial PFC (vmPFC). In a prospective study, 22 first-time mothers answered questionnaires about their PGI level 1 month before birth (T1) and 1 month after delivery (T2). Four months after giving birth, a follow-up assessment was applied with 16 of these mothers (T3). Structural brain data were acquired at both postpartal measurement occasions. Voxel-based morphometry was used to correlate prenatal PGI levels with postpartal gray matter volume. Higher PGI levels before delivery were positively associated with larger gray matter volume in the vmPFC directly after childbirth. Previous structural neuroimaging research in the context of major life events focused primarily on pathological reactions to stress (e.g., post-traumatic stress disorder; PTSD). The current study gives initial indications that proactive coping may be positively associated with gray matter volume in the vmPFC, a brain region which shows volumetric reductions in PTSD patients.

Project description:BackgroundMedically assisted reproduction is a vulnerable time for couples' sexual health. Believing that sexual challenges can be worked through (i.e., sexual growth beliefs) or that these challenges indicate incompatibility (i.e., sexual destiny beliefs) may be related to dyadic coping-the strategies couples use to cope-with the physical and psychological stressors of medically assisted reproduction.AimIn the current study we aimed to examine the longitudinal associations between typical (i.e., average) levels of sexual growth and destiny beliefs and positive and negative facets of dyadic coping and how greater than typical levels of these constructs predicted each other across time.MethodsCouples (n = 219) seeking medically assisted reproduction were recruited for an online longitudinal, dyadic study.OutcomesCouples completed online measures of sexual growth and destiny beliefs and positive and negative dyadic coping at baseline, 6-and 12-months.ResultsRandom intercept cross-lagged panel models demonstrated that at the within-person level, reporting higher sexual growth beliefs at baseline, relative to their average across time points, was associated with lower negative dyadic coping at 6 months. Higher negative dyadic coping at 6 months, relative to their average, was linked to lower sexual growth beliefs at 12-months. When individuals reported higher sexual destiny beliefs at 6-months, relative to their average, they and their partners reported higher negative dyadic coping at 12 -months. At the between-person level, higher overall levels of sexual destiny beliefs were related to higher overall levels of negative dyadic coping. No associations with positive dyadic coping were identified.Clinical implicationsCouples may benefit from identifying and reducing unhelpful beliefs about sex and negative dyadic coping.Strengths and limitationsStrengths of this study include our large, inclusive sample, engagement of community partners, and novel analytical approach to assess change over time. However, following couples in 6-month increments and not using questionnaires specific to medically assisted reproduction may have limited our ability to detect nuanced changes that couples experience during this time.ConclusionLower sexual growth and higher sexual destiny beliefs may promote couples' engagement in less adaptive coping behaviors as they seek medically assisted reproduction.

Project description:BackgroundThe impact of cardiovascular risk burden on cognitive trajectories and brain structure changes remains unclear.ObjectivesThis study aimed to examine whether cardiovascular risk burden assessed by the Framingham General Cardiovascular Risk Score (FGCRS) is associated with cognitive decline and structural brain differences.MethodsWithin the Rush Memory and Aging Project, 1,588 dementia-free participants (mean age: 79.5 years) were followed for up to 21 years. FGCRS was assessed at baseline and categorized into tertiles (lowest, middle, and highest). Episodic memory, semantic memory, working memory, visuospatial ability, and perceptual speed were assessed annually with a battery of 19 tests, from which composite scores were derived. A subsample (n = 378) of participants underwent magnetic resonance imaging. Structural total and regional brain volumes were estimated. Data were analyzed using linear mixed-effects models and linear regression models.ResultsIn all participants, FGCRS ranged from 4 to 28 (mean score: 15.6 ± 3.7). Compared with the lowest tertile of FGCRS, the highest tertile was associated with faster decline in global cognition (β = -0.019; 95% confidence interval [CI]: -0.035 to -0.003), episodic memory (β = -0.023; 95% CI: -0.041 to -0.004), working memory (β = -0.021; 95% CI: -0.035 to -0.007), and perceptual speed (β = -0.027; 95% CI: -0.042 to -0.011) over the follow-up. In magnetic resonance imaging data analyses, higher FGCRS was related to smaller volumes of the hippocampus (β = -0.021; 95% CI: -0.042 to -0.000), gray matter (β = -1.569; 95% CI: -2.757 to -0.382), and total brain (β = -1.588; 95% CI: -2.832 to -0.344), and greater volume of white matter hyperintensities (β = 0.035; 95% CI: 0.001 to 0.069).ConclusionsHigher cardiovascular risk burden may predict decline in episodic memory, working memory, and perceptual speed and is associated with neurodegeneration and vascular lesions in the brain.
