V5 Neuropsychology,Patient Impact And Family Considerations


After an individual damages the MT/v5 area of the

occipital lobe, it can be very beneficial for the

individual to go through neuropsychological evaluations to

assess their perceptual and cognitive abilities post-trauma

or surgery. A Neuropsychologist determines what tests are

appropriate to adequately identify the extent of the

cognitive and behavioral consequential effects associated

with the damage sustained by the MT/v5 area.

In the example of SF, the epileptic mentioned earlier

by (Nawrot et al, 2000), SF had a series of motion

perception test administered to determine the effects of

her surgery. In the case of SF, pre and post-surgery tests

were given to measure how the removal of the lesion in the

MT+ area of her occipital lobe effected her perceptual

abilities. The random dot cinematograms (RDC) test, was

selected to measure SF perception and the consequential

effects of damage sustained to her occipital lobe areas.

After these tests were administered, the Neuropsychologist

is able to rank the patients test score against the mean

scores that represent normal performance range. In the

case of SF, the perception tests were able to show the

amount of time it took for her MT/v5 area to adapt to its

new conditions. The Neuropsychologist then compares SF's

perceptual performance to her pre-surgery ranges. These

results helped (Nawrot et al, 2000) suggest that either

dendritic sprouting or the opposite hemisphere compensation

occurred in order to compensate for damage of SF MT/v5

area. The importance of these tests, are to help the

Neuropsychologist determine the necessary steps needed for

the rehabilitation of the patient. In the case of SF,

these results helped conclude that the removal of lesion in

the MT to reduce her seizures was worth it. The amount of

seizures was greatly reduced post surgery and the visual

and perceptual deficits experienced by SF after the surgery

were short lived.

Another example of the types of tests used by

Neuropsychologist to identify the effects of head trauma,

are illustrated in the case study of BC, a 45 year old

women with visual-perceptual deficits. (Vaina et al, 2002,

p. 465) The Performance part of the Wechsler Adult

Intelligence Scale-Revised (WAIS-R) was administered by the

Neuropsychologist to assess BC's perceptual and cognitive

abilities. Three tests in the Performance IQ set were

administered, Picture Completion, Block Design, and Object

In this essay, the author

  • Explains the importance of neuropsychological evaluations after an individual damages the mt/v5 area of theoccipital lobe.
  • Explains how the removal of the lesion in the mt+ area of sf's occipital lobe affected her perceptualabilities.
  • Describes how the neuropsychologist evaluates sf's perception and the consequential effects of damage sustained to her occipital lobe areas.
  • Explains the importance of these tests to help the neuropsychologist determine the necessary steps needed for rehabilitation of the patient.
  • Explains that the mt to reduce her seizures was worth it. the visual and perceptual deficits experienced by sf after the surgery were short lived.
  • Explains that the neuropsychologist administered the wechsler adult intelligence scale-revised (wais-r) to assess bc's perceptual and cognitiveabilities.
  • Explains that the neuropsychologist gave bc a test to determine her ability to interpret complex pictures or visual fields.
  • Explains the significance of this test to help the neuropsychologist identify whether or not bc would experience problems with object recognition.
  • Explains that mt/v5 area of the occipital lobe would cause temporary problems with visualperception, especially in motion perception. lesions within the area improve or even completely recover their previous perceptual abilities within a few days.
  • Explains that a head injury can cause emotional and other side effects beyond the occipital cortex. dr. dell orto and dr power's theorized in their book head injury and the family some of the potentialdetermining factors.
  • Explains that the personality type of an individual before the trauma seems to be the first important factor in how anindividual responds. dependent personality types are more inclined to become even more dependent onothers and social support post-trauma.
  • Explains that people who are concerned about their body image might have a hard time seeing themselves post-trauma that could lead to symptoms of depression.
  • Explains that a person who is blind or has limited visual processing is less likely to freak out after the affects of v5 trauma.
  • Explains that a neuropsychologist can give tests to see the extent of the trauma and givepotential rehabilitative activities for the patient topractice.
  • Explains that the fifth factor that impacts a patients reaction to head trauma isfamilial and societal reactions to the injury.
  • Explains that they experienced guilt, depression, and inadequacy after recognizing the financial consequences of their brain injury.
  • Opines that the family plays a significant role in the patient's reaction to the head injury.
  • Opines that the negative consequences of their condition were easily observed through their family members'thoughts and actions.
  • Explains that they felt guilty because it made their parents lifeharder. they adapted the behavior of not taking prescription medication, along with not seeking medical attention because of the absurd cost of medical care.
  • Narrates how their father reinforced the idea that if they were ever put on lifesupport, their parents would pull the plug, resulting in their death.
  • Narrates how they began to deny the severity of their head trauma condition due to their parents' reactions to it. this denial led them to lie to the theneurologist about the extent of my seizures.
  • Explains that they felt like they would die rather than live with this condition that has caused pain and suffering to their family as well as themselves.
  • Explains that visual deficits in a patient with kaleidoscopic disintegration of the visual world are related to regional cerebral correlates of global motion perception.
