  • Acquired Brain Injury (ABI) is an injury to the brain that occurs after birth, on a cellular level. Different factors can cause an ABI:
  • Traumatic Brain Injury (including concussion)
  • Anoxic Injuries (A Prolonged Lack of Oxygen)
  • Hypoxia (Decreased Oxygen Flow)
  • Neurotoxic Events (Exposure to toxic Chemicals)
  • Cerebral Ischemia (Restricted Blood Flow)
  • Infections, such as encephalitis or meningitis)
