DeepSummary
This NPR Shortwave podcast episode discusses the connection between domestic violence and traumatic brain injuries. It features an interview with NPR's brain correspondent Jon Hamilton, who explains how repeated head injuries from domestic abuse can lead to serious brain damage, including PTSD, memory loss, thinking problems, and dementia.
The episode highlights the story of Maria E. Garaisaratos, whose mother suffered severe brain trauma due to years of abuse by her father. An autopsy on her mother's brain revealed both Alzheimer's and chronic traumatic encephalopathy (CTE), a neurodegenerative disease caused by repeated head injuries.
Researchers have been studying the brains of women who died with a history of intimate partner violence to understand the unique patterns of brain injury caused by domestic abuse. While they did not find CTE, they discovered a distinct signature of brain damage, which could potentially serve as a biomarker to detect and stop domestic violence before it causes severe injury or death.
Key Episodes Takeaways
- Unlike sports injuries, brain injuries from domestic violence often occur without opportunities for healing between incidents.
- Identifying biomarkers for brain injuries from domestic violence could help detect and stop the violence before severe injury or death occurs.
- The brain damage caused by domestic violence may differ from that caused by contact sports, warranting further research into its unique patterns and effects.
- Domestic violence is a leading cause of traumatic brain injuries, affecting more people than contact sports or military service.
- Brain injuries from domestic violence can lead to PTSD, memory loss, thinking problems, and dementia.
- Repeated head injuries in domestic violence settings can cause chronic traumatic encephalopathy (CTE), a neurodegenerative disease.
- Researchers are studying the brains of domestic violence victims to identify unique patterns of brain damage that could serve as biomarkers for detection and prevention.
- Non-fatal strangulation, which deprives the brain of oxygen, is a common form of injury in domestic violence cases, contributing to brain damage.

- “She's the one that said, you know what? Your mom had an immense amount of trauma to the head. She had the worst brain impacted by this that she had ever seen.“ by Maria E. Garaisaratos
- “If we have a biomarker where you don't actually have to look in the tissue with a biopsy or wait till the person's dead, for God's sakes, to make the diagnosis, this is what we're ultimately all trying to do.“ by Rebecca Fulcreth
- “We have heard several people make these comparisons and say, oh, well, intimate partner violence is the female equivalent of football. And that seemed to be such an unbelievably, dangerously off base comment, but we couldn't know until we studied it, because.“ by Kristen Domz O'Connor
- “On top of those patterns, we also see very high rates of non fatal strangulation.“ by Kristen Domz O'Connor
