The brain can receive several different types of injuries depending on the type of force and amount of force that impacts the head. The type of injury the brain receives may effect just one functional area of the brain, various areas, or all areas of the brain.
Acquired brain injury takes place at the cellular level within the brain. Therefore, injury from acquired brain injury can effect cells throughout the entire brain, instead of just in specific areas as with traumatic brain injury.
Most symptoms of acquired brain injuries are very similar to that of traumatic brain injuries; however, there are some difficulties that are experienced more frequently or to a greater degree by persons with acquired brain injuries. These symptoms can include:
Cognitive impairment- Thinking skills, especially memory
Longer lengths of time spent in a vegetative state
Severe behavior problems- Psychosis, depression, restlessness, combativeness, hostility
Muscle movement disorders
