Primary objective: Despite a high prevalence of intimate partner violence (IPV) and its lasting impacts on individuals, particularly women, very little is known about how IPV may impact the brain. IPV is known to frequently result in traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD). In this overview of literature, we examined literature related to neuroimaging in women with IPV experiences between the years 2010-2021.
Research design: Literature overview.
Methods and procedures: A total of 17 studies were included in the review, which is organized into each imaging modality, including magnetic resonance imaging (structural, diffusion, and functional MRI), Electroencephalography (EEG), proton magnetic resonance spectroscopy (pMRS), and multimodal imaging.
Main outcomes and results: Research has identified changes in brain regions associated with cognition, emotion, and memory. Howeverto date, it is difficult to disentangle the unique contributions of TBI and PTSD effects of IPV on the brain. Furthermore, experimental design elements differ considerably among studies.
Conclusions: The aim is to provide an overview of existing literature to determine commonalities across studies and to identify remaining knowledge gaps and recommendations for implementing future imaging studies with individuals who experience IPV.
