Symptoms of Acquired Brain Injury
Unlike a traumatic brain injury, an acquired brain injury occurs on a cellular level within the brain, which means that instead of one area of the brain being affected – such as the one that governs speech or movement – cells throughout the entire brain are affected. Despite the difference in the type of injury, signs and symptoms of an acquired brain injury are strikingly similar to those of a traumatic brain injury. However, some signs or symptoms are experienced more frequently or are more pronounced in people with acquired brain injuries. In particular, these are:
- Cognitive impairment when it comes to thinking skills, memory skills in particular
- Longer time spent in a coma or vegetative state
- More pronounced behavioral issues such as anger, hostility, combativeness, depression, restlessness, and psychosis
- Muscle movement issues
If a person experiences the above signs or symptoms following a blow to the head or after experiencing one of the major causes of acquired brain injury, such as airway obstruction, electrical shock or lightning strike, vascular disruption, infectious disease, or toxic exposure to poisonous chemicals or gases, a physician should be seen immediately.
