The study of brain injury has been an area of interest for many scientists in the world. For
instance, scientists in the fields such as psychiatry, neuropsychology, and neurosurgery as well as
neurology, have conducted studies on the injured brains, especially on the members of the
military from war zones. Many of those who experience brain injuries are either in the army or
the boxing or other sports involving fighting. Based on the type or the extent of the brain injury
sustained, most of the affected people often develop some kinds of behavior which lead to
deaths. This article explains, based on research, how damaged suffered by the brain can lead to
behavior changes.
Brain injury is damage which leads to the destruction of specific cells of the brain. There
are two main types of the brain. These include the traumatic brain injury (TBI) and Acquired
brain injury (ABI) (Chakraborty, et al., 2018.). These two damages disrupt the functionality of
the brain leading to different kinds of behavior in a person. TBI results from external forces, like
a blow or kick on the head, or even a fall on a hard surface, leading to the damage of the skull
and consequently the brain. On the other hand, ABI occurs in the cells and often results from the
pressure put upon the brain such as from tumors or other neurological conditions (Durham &
Ramcharan, 2018 ). When the brain is thus affected, the standard functionalities are interfered
with, and this may include making impaired judgments as well as actions (Raymont, et al.,
2011).
Research suggests that most of the people who commit crimes have at one time been
affected in their brain. For instance, some of the domestic violence perpetrators have been
identified to have suffered brain damages earlier in life. According to, Grafman et al. (2011), in
the "Vietnam Head Injury Study," suggests that most people behave the way they do base on

their past experiences and damages sustained on the head which led to the destruction of brain
tissues. This, in essence, suggests that most of the crimes committed by some of the ex-military
personnel may not be from their judgmental perception, instead of their inability to make
informed decisions (MacDonald, et al., 2014). Different disorders may result from brain injuries,
which also define the extent of change in behaviors among the affected individuals.
In conclusion, brain injury is related to human behavior and the scientists, especially over
recent years, are seeking for ways through which they can make the connections and understand
different behavioral changes resulting from the various extents of brain damage, and how such
damages can be medically addressed to make sure that the people affected are not adversely
affected after treatment.
