An acquired brain injury is brain damage/dysfunction that was caused by an event and can be either traumatic such as with concussion and TBIs, or non-traumatic such as stroke, hypoxia, ischemia, infection, or toxins/poisons. People with acquired brain injuries may or may not have finding on MRI or CT scans. Often there are symptoms regarding movement, sensation, cognition and/or emotional systems. Acquired brain injuries can occur at any age from birth as with hypoxic ischemic encephalopathy, to childhood non-fatal drowning anoxic brain injuries, to adolescent concussions and poisonings, to heart attack and stroke in adulthood.
