Signs of domestic abuse or intimate partner violence (IPV) are often pictured as bruises, broken bones or black eyes. The concurrent invisible injury such as brain trauma in women is often unnoticed. A study of women who sustained domestic violence found that:

  • Internationally, 30% of women over the age of 15 report IPV
  • An estimated 92% reported that their partners hit them more than once
  • Up to 83% reported being both hit in the head and severely shaken
  • 8% disclosed they were hit in the head more than 20 times in the past year (Jackson, 2002) Visit
  • Up to 75% of sampled women who experienced IPV have suffered multiple partner-related traumatic brain injuries (Valera EM, 2016)  Visit


OBIA is raising awareness

OBIA is actively involved in raising awareness of the connection between IPV and concussion throughout Ontario. IPV can occur in people of all ages, genders, sexual orientations, socioeconomic classes, levels of education, races and cultures; however, it disproportionately happens to women.

If your organization is interested in finding out more about how OBIA can educate and support your front line workers in recognizing symptoms of a brain injury, please contact us at 1-800-263-5404.

For support, please contact or phone our helpline: 1-800-263-5404.
