This white paper is the first of three parts on the complex functions of brain, what happens when an injury is acquired and how to care for and manage a life-changing brain injury. BY LINDA SIMMONS, RN BScN Senior Nurse Life Care Planner, Connect Medical Legal Experts This document will increase the health care professionals understanding of Acquired Brain Injury (ABI). ABI is defined as damage to the brain that is acquired after birth. It can affect cognitive, physical, emotional, social, or independent functioning. ABI is an umbrella term used to describe all brain injuries. ABI can result from traumatic brain injury (i.e. accidents, falls, assaults, etc.) and non-traumatic brain injury (i.e. stroke, brain tumours, infection, poisoning, hypoxia, ischemia or substance abuse). The motor vehicle related accident clients that we at Connect Experts see with ABI have often resulted from a Traumatic Brain Injury and thus ABI’s that have resulted from a TBI will be the focus of this document.
