Summary
Women survivors of repetitive intimate partner violence (IPV) with traumatic brain injury (TBI) showed lower white matter integrity, particularly in the corpus callosum. This brain injury impacts cognitive function, highlighting the neurological effects of repeated IPV-TBI.
Area of Science:
- Neuroscience
- Neurology
- Trauma Research
Background:
- Intimate partner violence (IPV) frequently causes traumatic brain injury (TBI) in women survivors.
- Repetitive IPV-TBI is common, yet neurological outcomes remain understudied.
- Existing research indicates structural and functional neuroimaging changes post-IPV-TBI.
Purpose of the Study:
- To investigate differences in white matter integrity between women survivors of IPV with and without a history of repetitive IPV-TBI.
- To assess the relationship between white matter integrity and fluid cognitive functioning in this population.
- To contribute to the understanding of neurological consequences of repetitive IPV-TBI.
Main Methods:
- A case-control pilot study comparing 11 women with repetitive IPV-TBI and 11 women without IPV-TBI history.
- Diffusion tensor imaging (DTI) was used to assess white matter integrity via tract-based spatial statistics (TBSS).
- Cognitive function was evaluated using the NIH Toolbox Cognition Battery.
Main Results:
- Significant differences in white matter integrity were observed between groups, notably in the posterior corpus callosum and left anterior thalamic radiation.
- Lower white matter integrity was associated with reduced fluid cognitive functioning in the overall sample (rho = -0.44, p = 0.040).
- This association was not significant when stratified by IPV-TBI group.
Conclusions:
- Repetitive IPV-TBI history is associated with reduced white matter integrity in women survivors.
- White matter integrity is linked to fluid cognitive abilities across the study sample.
- This study underscores the physical neurological impact of repetitive IPV-TBI and informs future research directions.
