Traumatic Brain Injury Essay

Traumatic brain injury (TBI) is a sophisticated problem because of different reasons. Among the reasons are their difficulties to be diagnosed early in majority of the cases. This is because either the damage in most cases is not visible or the brain trauma does not receive the attention it deserves since patients with head injuries often times have other injuries. The other problem with head injury is that it is associated with numerous disorders and often results in different psychological symptoms that can complicate the diagnosis and treatment. It may be associated with depression, personality problems, anxiety, paranoia, or apathy. Impulsive aggression which this paper deals with is one of the challenging and complex problems that …show more content…
This form of aggression has also been termed predatory, instrumental, or proactive. Premeditated aggression is not invariably accompanied by autonomic arousal and is planned with clear goals in mind (Schwarzbold et, al. 2008).
Although Impulsive aggression is known to be one of the most common consequences of TBI, there are many other factors associated with human aggression. Understanding the factors that contribute to this may provide important clues for the prevention and treatment of impulsive aggression after TBI, thus improving the rehabilitation potential in the crucial early post-TBI period. With this in mind, the paper examines the neurobiological, neuropsychological and psychosocial contributors of impulsive aggression after brain injury.
Aggression after TBI is associated with multiple neurobiological neuropsychological and psychosocial factors. In the search for a neurobiological substrate of aggressive behavior, the frontal cortex has been a primary target since the case report of Phineas Gage. Many authors reported frontal lobe damage that appeared to be linked to aggressive behavior. Such cases typically involved lesions of the prefrontal, especially the orbitofrontal cortex. Blair (2003) mentioned that this aggression is almost exclusively reactive (impulsive) compared with the more instrumental, goal-directed aggression shown by individuals with ‘‘developmental’’ aggression (Weber et, al., 2008).
