In a latest study of the brains of 84 deceased ladies who skilled intimate companion violence, Dr. Kristen Dams-O’Connor and colleagues discovered that the brains constantly confirmed indicators of traumatic brain injury however that none met the factors for persistent traumatic encephalopathy (CTE). Mount Sinai Medical Center emphasizes the groundbreaking nature of this examine, saying, “Regardless of how frequent intimate companion violence is – it impacts one in three ladies sooner or later of their lives – remarkably little is understood concerning the neuropathology of companion violence.”

The examine, revealed in Acta Neuropathologica, was divided into two case sequence. The primary sequence examined the brains of 14 ladies from New York, obtained over two years. The second was an archival case sequence that examined 70 brains, 61 of which got here from ladies from Manitoba and 9 of which got here from Join-TBI, a multi-center examine. The entire brains in each sequence got here from ladies who have been confirmed to have skilled intimate companion violence. Additionally they got here from a racially numerous group of individuals and ranged in age from their 20s to their 70s. 

Dams-O’Connor et al. obtained the ladies’s medical histories for the primary case sequence and the brains obtained by Join-TBI. They then evaluated the brains for neuropathologic modifications indicative of CTE and different neurodegenerative ailments by staining samples and taking a look at particular slides through ex vivo neuroimaging. The brains from Manitoba have been break up into two teams; 29 had a whole examination by a neuropathologist, whereas the opposite 31 have been photographed and stained.

Almost the entire brains confirmed “vascular and white matter pathologies” related to traumatic brain injury, in addition to some proof of neurological ailments. Nonetheless, none confirmed indicators of CTE, a progressive neurodegenerative illness generally discovered within the brains of male contact athletes who’ve suffered repeated traumatic mind accidents and, particularly, repetitive head impacts of all ranges. This discovering raises questions on underneath what circumstances CTE can happen and reveals that there’s a want for extra analysis into the long-term results of traumatic mind accidents in populations who’re underrepresented in concussion analysis, like survivors of intimate companion violence.

Whereas this examine does give some perception into the connection between intimate companion violence and traumatic brain injury, Dams-O’Connor et al. acknowledge that the examine was carried out on a comparatively small pattern, so the generalizability of the outcomes is unclear. Nonetheless, this examine does pave the best way for additional analysis into how traumatic mind accidents current in populations whose brains haven’t been studied extensively on this subject.
