Varsha to the head, the brain becomes in

Varsha might report visual
disturbances due to a concussion or otherwise known as mild traumatic brain
injury (TBI). A concussion is a brain injury which can affect the function of
the brain. It could either be minor or major and are usually caused by a
forceful “blow to the head” from striking an object. (HockeyCanada 2017) As Varsha was not wearing a helmet, when a
hockey stick suddenly struck her head, it may have instigated the head to snap
forward, back or to the side. The brain is surrounded by cerebrospinal fluid so
when the head snaps, to one of three directions, the impulsive force triggers
movement of the brain within the skull which generally leads to a change of
brain function. (HockeyCanada 2017) This
causes concussion signs and symptoms. The cerebrospinal fluid cushions the
brain and protects it from contacting the interior walls of the skull during
every day activity. By this the axons of the neurones in the brain are
protected. If a person was to suffer a hard blow to the head, the brain becomes
in contact with the insides of the skull. This may result in damaged axons and
also decrease normal brain function by interrupting communication between
neurones. (TBI Recovery Centre 2017) Symptoms
of concussion can be physical, cognitive or emotional. Physical symptoms
include dizziness, cognitive symptoms include memory loss and emotional
symptoms include signs of depression. Symptoms of visual disturbances such as:
blurred vision, headaches, double vision and visual field loss also tie in with
physical and cognitive symptoms and could be a result of the occipital lobe
being affected. The two main areas of the brain that are affected the most in
Varsha as a result of her attack are the frontal and temporal lobes. This is
because these two parts of the brain are naturally situated closest to the
skull and she was hit on her forehead. In addition, the neck is located behind
the skull so when the head rotates the front of the head moves further than the
rest of the head. As a result of the frontal and temporal lobes moving at
greater lengths, more damage is done to these particular areas of the brain. (Kelly 2008) The frontal lobe, which is
positioned in the front of the brain, controls personality. It encourages
cognitive functions such as organising and planning. The temporal lobe, which
is positioned in the lower central part of the cortex underneath the temples, is
associated with memory and language. Depending on the severity of the injury, if
the temporal lobe is impaired memory functions can be impacted which can have a
perpetual effect. Memory functions include verbal memory in the left hemisphere
and visual memory in the right hemisphere. Other symptoms Varsha may exhibit
include inability to focus and concentrate due to the frontal lobe being
affected; constant headaches also due to the frontal lobe being affected and
memory loss due to the temporal lobe being affected. (Kelly 2008) It could be a possibility that Varsha suffered a
coup-contrecoup injury. A coup-contrecoup injury is when the brain is damaged
on two sides. The site that she received initial impact was the forehead so the
frontal and temporal lobes were impacted. The opposite side (rear portion of
the skull) may have also been impacted. The occipital lobe is located at the
back of the skull and as Varsha suffered visual disturbances, it suggests that
the occipital lobe was also affected as a result of the injury. (TBI Recovery Centre 2017)
